Systematization of food and nutrition education content based on national kindergarten curriculum: a qualitative formative study: Jung-Hyun Kim, Eugene Shim, Eunyoung Baik; Korean J Community Nutr 2023;28(6):509-522. Published online December 31, 2023; DOI: https://doi.org/10.5720/kjcn.2023.28.6.509

Abstract PDF: Objectives
This study is intended to develop a curriculum for kindergarten food and nutrition education aimed at preschool children, reflecting government policy and meeting the demands of preschool settings.
Methods
Existing educational materials were analyzed, and key elements of the 2019 Revised Nuri Curriculum (“Nuri Curriculum”) and Guidelines for Nutrition and Food Education in Kindergartens, Elementary, Middle, and High Schools (“Guidelines”) were examined as foundational information for developing the curriculum for food and nutrition education.
Results
Basing ourselves on the five domains of the Nuri Curriculum, “Physical Activity and Health,” “Communication,” “Social Relationships,” “Art Experience,” and “Natural Science Inquiry,” we integrated three areas from the Guidelines, namely “Dietary Habits and Health,” “Dietary Habits and Safety,” and “Dietary Habits and Culture,” to structure the curriculum for kindergarten food and nutrition education. Three specific domains, “Nutrition and Health,” “Food and Culture,” and “Safe Dietary Practices,” were tailored for preschool children, each comprising core concepts, content elements, and educational materials. In the “Nutrition and Health” domain, core concepts such as “nutrition” were addressed through content elements such as “balanced eating” and “vegetables and fruit,” while “health” included elements such as “eating regularly” and “nutrients for disease prevention,” each with two educational content components. The “Food and Culture” domain focused on “food” with content on “local foods (vegetable-garden experience)” and “food culture” with content on “our dining table (rice and side dishes),” “our agricultural products,” “global cuisine (multiculture),” and “considerate dietary practices,” each with four educational content components. The “Safe Dietary Practices” domain included core concepts such as “hygiene” with content on “hand-washing habits” and “food poisoning management,” and “safety” with content on “food labeling.” Conclusions: The systematized curriculum for kindergarten food and nutrition education aligns with the Nuri Curriculum and is interconnected with the Guidelines. This curriculum can be used as foundational material for developing educational resources tailored to the characteristics of preschoolers, contributing to effective implementation in early childhood education.

Screen time, mealtime media use, and dietary behaviors in Korean preschoolers : a cross-sectional study: Young-Hee Han, Saerom Shin, Eun Yeol Woo, Hye-Kyung Park, Taisun Hyun; Korean J Community Nutr 2023;28(3):206-219. Published online June 30, 2023; DOI: https://doi.org/10.5720/kjcn.2023.28.3.206

Abstract PDF: Objectives
Screen time refers to the time spent using screen media, such as televisions, smartphones, computers, or tablets. Excessive exposure to screen media has been reported to negatively impact young children’s health and development, including overweight, short sleep duration, and language delays. This study examined the association of screen time and mealtime media use with dietary behaviors among preschool children.
Methods
A cross-sectional survey was conducted on parents of children aged three to five years using the online questionnaires of the Nutrition Quotient for Preschoolers (NQ-P) and the Dietary Screening Test (DST). Data from 261 children’s parents were analyzed.
Results
Of the 261 children, 96.9% used screen media, 55.6% used screen media for two hours or more daily, and 30.7% were exposed to screen media during meals. The NQ-P scores were significantly lower in the children with longer screen time and mealtime media use. Children who used screen media for two hours or more and those exposed to screen media during meals consumed kimchi less frequently and confectionery and sugar-sweetened beverages more frequently than children who used less than two hours and were not exposed to screen media during meals. In addition, they were more likely to be picky about food, refuse to eat, and less likely to feed themselves than children with shorter screen time and no mealtime media use.
Conclusions
This study reported an association between unhealthy dietary behaviors, feeding difficulties, and screen time and mealtime media use among preschool children. Further research should explore effective strategies for reducing children’s screen time.

Development of a Zinc Database to Estimate the Zinc Intake Levels in the Korean Toddlers and Preschool Children: Su-In Yoon, Jae Eun Shim; Korean J Community Nutr 2021;26(2):103-110. Published online April 30, 2021; DOI: https://doi.org/10.5720/kjcn.2021.26.2.103

Abstract PDF

Objectives
The objective of this study was to develop a zinc database (DB) to estimate the intake levels of zinc in Korean toddlers and preschool children using the data from the Korea National Health and Nutrition Examination Survey (KNHANES). Methods: A total of 3,361 food items for the DB representing the usual diet of Korean toddlers and preschool children were selected based on KNHANES (2009~2013) and the food composition table of Rural Development Administration (RDA). The existing values of zinc in foods were collected from the latest food composition tables of RDA (9th revision) and the US Department of Agriculture (legacy release). The zinc contents were filled preferentially with these collected values. The missing values were replaced with the calculated values or imputed values using the existing values of similar food items from the data source. The zinc intake levels of Korean toddlers and preschool children were estimated using KNHANES and zinc DB Results: A total of 1,188 existing values, 412 calculated values, and 1,727 imputed values were included in the zinc DB. The mean intake levels of zinc for 1-2-year-old children and 3-5-year-olds were 5.17 ± 2.94 mg/day and 6.30 ± 2.84 mg/day, respectively.There was no significant difference in the zinc intake levels between boys and girls in each group. Conclusions: This newly developed zinc DB would be helpful to assess the zinc nutritional status and investigate the association between the zinc intakes and related health concerns in Korean toddlers and preschool children.

Relationship between the Dietary Behavior of Young Children and Their Mothers in Daejeon, Korea Using the Nutrition Quotient for Preschoolers and Adults: InYoung Jeong, SuJin Song; Korean J Community Nutr 2021;26(1):12-22. Published online February 28, 2021; DOI: https://doi.org/10.5720/kjcn.2021.26.1.12

Abstract PDF

Objectives
This study examined the association between the dietary behavior and weight status of preschool children and their mothers in Daejeon, Korea. Methods: A total of 301 mother–preschool children (aged 3~6 years) dyads were included in this study. The dietary behavior of children and their mothers was assessed using the Nutrition Quotient (NQ) questionnaire for preschoolers and adults, respectively. The NQ questionnaires were completed by the mothers. The overweight/ obesity status of children and their mothers was determined using data on height and body weight reported by the mothers. Multiple logistic regression was performed to examine the relationship between the dietary behavior and weight status of children and their mothers. Results: The mean NQ score was 58.9 ± 9.7 in children and 55.6 ± 9.2 in mothers. The NQ score was higher in boys than girls but did not vary by age. The prevalence of overweight/obesity was 27.5% in children and 46.5% in mothers. The physical activity level of mothers and their NQ scores were positively associated with the NQ scores of the children. After adjustment for covariates, the mothers in the highest tertile of NQ scores showed a lower odds ratio (OR) for the unhealthy dietary behavior of children (OR = 0.24, 95% CI = 0.11~0.53, P< 0.001) compared to those in the lowest tertile. The obese mothers showed a higher OR for children’s overweight/obesity (OR = 3.38, 95% CI = 1.68~6.80, P = 0.001) compared to normal weight mothers. Conclusions: The dietary behavior and weight status of young children and their mothers were closely linked. Nutrition education programs targeting mothers are necessary for improving maternal and child nutrition. Specifically, these programs need to be tailored to the socioeconomic characteristics or weight status of mothers.

Association between Picky Eating Behavior, Growth, and Dietary Practices in Preschool Children: Jisun Kim, Sukyoung Kang, Seunghee Kye; Korean J Community Nutr 2021;26(1):1-11. Published online February 28, 2021; DOI: https://doi.org/10.5720/kjcn.2021.26.1.1

Abstract PDF

Objectives
This study was conducted to assess the eating behavior, growth, and dietary practices of children aged 3~5 years living in the Seoul and Gyeonggi Provinces. Methods: Self-administered questionnaires were completed by 237 mothers of preschool children between April and June 2018. Z-scores for weight-for-age, height-for-age, and BMI-for-age were calculated to determine the children’s growth status. Dietary practices were evaluated using the nutrition quotient for Korean preschoolers (NQ-P). Results: In our study, 29.5% of children were in the eating-small-amounts group, 46.8% of children were in the neophobic behavior group, and 61.2% of children were in the refusal-of-specific food group. Specific foods found to have a high frequency of rejection are listed in descending order as follows: shellfish, soy, mushroom, shrimp, vegetables, milk, eggs, yogurt, seaweed, meat, fruits, and fish. The eating-smallamounts group had lower Z-scores for weight-for-age, height-for-age, and BMI-for-age than the non-picky eaters’ group. Compared to the non-picky eaters' group, the eatingsmall-amounts group of picky eaters had lower scores on the moderation and environment items of the NQ-P, the neophobic behavior group had lower scores on the balance and environment items of the NQ-P, and the refusal-of-specific food group had lower scores on the balance, moderation, and environment items of the NQ-P. Conclusions: Children classified with picky eating behavior had lower growth and development, lower diet diversity, less balanced food intake, and had greater difficulty in abstaining from eating unhealthy foods than non-picky eaters. Therefore, a lot of patience and intensive efforts are needed to encourage children to encounter, experience, and accept unfamiliar food. It is more effective to provide eating behavior guidance by gently encouraging children, than by being strict and forceful. Besides, since the eating behavior of children is influenced maximally by the dietary lifestyle at their homes, it is important to ensure that a healthy dietary lifestyle is maintained at home.

Evaluation of Nutritional Status among Primary School Children in Uganda: Comparison of Urban and Rural Areas: Ji-Yeon Lee, Hye-Jung Park, Min Yu, Ha-Yeong Hwang, Jung-Rim Sung, Hee-Seon Kim; Korean J Community Nutr 2020;25(2):91-101. Published online April 30, 2020; DOI: https://doi.org/10.5720/kjcn.2020.25.2.91

Abstract PDF: Objectives
The aim of this study was to investigate dietary intakes and nutritional status among Uganda primary school children from two selected schools in urban and rural areas.
Methods
Data were collected from 350 pupils (6-14 years) in Mpigi district, Uganda. All participants were offered a school lunch meal (usually maize porridge and boiled beans). Dietary survey was conducted in October 2016. Data for dietary intake levels were collected by the 24-hour recall method with trained school staffs. The data were converted into nutrient intakes using the CAN-Pro 5.0 Program and compared with KDRIs to evaluate the nutritional status of the subjects. Diet quality indexes such as nutrient density, nutrient adequacy ratio (NAR), mean adequacy ratio (MAR), and index of nutritional quality (INQ) and a diet diversity index such as diet diversity score (DDS) were calculated to evaluate nutritional status among subjects. Data were analyzed using SPSS statistical programs.
Results
Results show that the intakes of most nutrients were significantly different by schools. The nutritional status of micro-nutrients was very low in both schools according to analysis of nutritional indexes such as NARs and INQs. Students from both schools should improve intakes of micro-nutrients related to child growth such as calcium, Vitamin B6, zinc and folate. According to the analysis of dietary diversity, there was difference in dietary patterns by schools presumably due to their locations.
Conclusions
This suggests that current meals could not provide adequate nutrients for the subjects and urgent nutrition interventions for school food services are needed to improve their nutritional well-being. New foods supplements based on local cuisine are also needed to ensure dietary diversity and sustainable development plans.

Relationships between Obesity and Dietary Habits of Preschool Children and Their Parents in Dongducheon Based on the Nutrition Quotient (NQ): Ji Myung Kim, Hye Jeong Song, Young Ji Ahn; Korean J Community Nutr 2018;23(3):216-225. Published online June 30, 2018; DOI: https://doi.org/10.5720/kjcn.2018.23.3.216

Abstract PDF PubReader

OBJECTIVES
This study was conducted to investigate the associations between obesity and the children's Nutrition Quotient (NQ) and to further examine the relationships between NQ and mini dietary assessment (MDA) of their parents.
METHODS
The subjects were 355 children aged 3 to 5 years and their parents in Dongducheon. We collected parental-reported NQ questionnaires for children and MDA of parents. Anthropometric measurements, height, weight and BMI by BIA were measured in children. Overweight and obesity were determined according to age- and sex-specific BMI percentile from the 2007 Korean national growth chart. Statistical analyses consisted of the chi-squared test, ANOVA, partial correlations and logistic regression analysis adjustments for parents BMI.
RESULTS
Approximately 20.8% of preschool children were classified as overweight or obese. Underweight children showed a significantly higher score for balance than overweight children. The NQ of the children was 61.9 Â± 11.6, and NQ scores and their parents' MDA did not exhibit any significant differences according to degree of obesity. After adjusting for parent's BMI, children's BMI was significantly correlated with balance and moderation among NQ factors. Parent's MDA showed significant correlation with their children's NQ, balance, diversity, moderation, regularity, practice and NQ grade, except for diversity of father. Additionally, NQ grade had a significantly increased (150.1%) odds ratio (OR) of being overweight (95% CI 1.008â€“2.234).
CONCLUSIONS
These results show that NQ for children is influenced by their parents' MDA and BMI. Furthermore, our findings support the association between overweight prevention and improvement of NQ grade among preschool children.

Comparison of Physical Activity Level, Physical Activity Pattern and Energy Expenditure in Male and Female Elementary School Soccer Players using Accelerometer and Physical Activity Diary: Hae Sun An, Su Ji Choi, Mo Ran Lee, Jung Sook Lee, Eun Kyung Kim; Korean J Community Nutr 2017;22(6):529-542. Published online December 31, 2017; DOI: https://doi.org/10.5720/kjcn.2017.22.6.529

Abstract PDF PubReader

OBJECTIVES
The purpose of this study was to compare the physical activity level (PAL), the physical activity pattern and the energy expenditure in male and female elementary school soccer players using the accelerometer and the physical activity diary.
METHODS
Twenty-five (male 11, female 14) elementary school soccer players (9â€“12 years) participated in this study. During their daily activities, they wore an accelerometer for seven days (five weekdays and two weekend days) and completed the physical activity diary for three days (two weekdays and one weekend day). PAL was calculated by using the physical activity diary and three equations (Pate Preschool, Freedson Children, and Freedson) were used to calculate the intensity of physical activity and energy expenditure from the counts of accelerometer.
RESULTS
The average of physical activity by day of the week, CPM (Counts Per Minute) and METs (Metabolic Equivalents) were significantly higher in males (723.3 Â± 149.2 CPM, 2.07 Â± 0.18 METs) compared to females (505.6 Â± 119.9 CPM, 1.79 Â± 0.20 METs), but there was no significant difference in PAEE (Physical Activity Energy Expenditure) between the two groups (males: 15.5 Â± 9.1 kcal/day, females: 11.5 Â± 6.0 kcal/day). During weekdays, physical activity intensity was significantly higher in males compared to females at lunch time and training time than at other times. In both genders, the PAL was higher during weekdays (males 1.98, females 1.89) compared to weekend (males 1.62, females 1.61) (p<0.05).
CONCLUSIONS
Our study observations suggest the necessity to develop an accelerometer equation for accurately evaluating the physical activity of elementary school athletes.

Abstract PDF PubReader

OBJECTIVES
This study was conducted to investigate the nutritional status and dietary behavior of Korean and Chinese elementary school children using Nutritional Quotient (NQ).
METHODS
The survey was conducted by distributing questionnaires to the parents of the child, after selecting four elementary schools located in Pusan city of Korea and three elementary schools located in Luoyang city, Henan Province of China, from Grade 1 to Grade 6 in each school.
RESULTS
The NQ scores of Korean children and Chinese children were 64.99 and 66.57, respectively, which did not show a statistically significant difference. Korean children significantly showed higher diversity score (p<0.001) than Chinese, but Chinese children significantly showed higher moderation (p < 0.001), regularity (p < 0.001) and practice score (p < 0.01) than Korean. NQ grades showed a statistically significant difference. According to food security of the household, NQ scores of the Chinese children of secure household were significantly higher than those of food insecurity household (p < 0.01). In particular, it showed a significant difference in the practice (p < 0.001), moderation (p < 0.05) and regularity score (p < 0.05). Korean children's NQ score showed a significant correlation with the score of following the Dietary Guidelines of parents, but Chinese did not show such a correlation.
CONCLUSIONS
There were differences in children's dietary behaviors and parents' impact to children's dietary attitude between Korean and Chinese. NQ developed for Korean could be successfully applied to Chinese.

Mother's Parenting Style at Meal Time and Their Preschooler's Dietary Behavior: Soyeon Park, Youngmee Lee; Korean J Community Nutr 2017;22(1):13-21. Published online February 28, 2017; DOI: https://doi.org/10.5720/kjcn.2017.22.1.13

Abstract PDF PubReader

OBJECTIVES
This study was conducted to evaluate the nutrition quotient (NQ) by mother's parenting style which may influence the NQ in preschool children.
METHODS
Subjects were 310 mothers and their 4-6 year old children. The questionnaire composed of demographic characteristics, mother's parenting style at meal time and eating behavior as measured by NQ questions. The NQ questions consisted of 19 food behavior checklist items and all items were grouped into 5 factors: balance, diversity, moderation, regularity, and practice. Mother's parenting style was classified by using words for nutrition education at meal time. All data were statistically analyzed by SPSS program (Ver. 23) and the statistical differences in variables were evaluated by Student's t-test, Ï‡Â²-test, One-way ANOVA.
RESULTS
We observed that in children whose mothers use the parenting style at meal time of â€˜explanationâ€™ and â€˜compliment & cheer upâ€™ had high dietary regularity, diversity, practice. The children of mothers who use the parenting style at meal time of â€˜persuasionâ€™ and â€˜rewardâ€™ were found to have a lower degree of balance, diversity, and practice. Especially, children of â€˜rewardâ€™ style mothers had lower moderation of dietary life. On the other hand, among the parenting style at meal time of â€˜comparison & demandâ€™, â€˜treatingâ€™ and â€˜faireâ€™, there was no significant difference in the NQ factor by each group. NQ grade was higher among those who used more explanation (p < 0.001) and persuasion (p < 0.01) and with use of less persuasion (p < 0.01) and reward (p < 0.01). The positive association observed between the frequency of dietary education of mothers and higher NQ grade indicated the degree of dietary practices of those children. On the other hand, the children of mothers who rarely practice the dietary education at home had lower NQ grade (p < 0.001).
CONCLUSIONS
In order to promote children's proper dietary behaviors, it is important to provide nutrition education to children as well as provide guidance on parenting style at meal time.

Food Allergy Awareness and Nutritional Management by the Parents of Preschool Children: Soo Bin Kim, Jung Hee Kim; Korean J Community Nutr 2016;21(5):426-439. Published online October 31, 2016; DOI: https://doi.org/10.5720/kjcn.2016.21.5.426

Abstract PDF PubReader

OBJECTIVES
This study was performed to measure the food allergy (FA) awareness and management by the parents of preschool children.
METHODS
A questionnaire survey was conducted with the parents of preschool children. The questionnaire was designed to identify the prevalence of food allergies, requirements of food allergy support and differences in food management according to the presence or absence allergic diseases, using a modified International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire. After excluding incomplete responses, the data of 158 parents of preschool children (90.3%) was used for statistical analysis.
RESULTS
The rate of the preschool children who had experienced food allergy (FA, ever) was 38.6% while diagnosed for food allergy by doctor (Diagnosis of FA, ever) was 17.7%. Forty nine preschool children (80.3%) had food restriction, and twenty three of them (37.7%) had self-restriction without diagnosis. The consumption frequencies of allergenic foods in FA group, such as ramyeon, noodles, bread, eggs, yogurt and ice cream were significantly (p<0.001) lower than those of the other two groups. The major allergenic foods were eggs, milk, wheat and processed foods in FA group. The overall food allergy-related knowledge level of parents was insufficient. Only 26 parents (16.5%) had received training about food allergies. All parents wanted to receive food allergy-related supports. In addition, most of parents wanted information on substitute menu for children with food allergy.
CONCLUSIONS
This study identified a lack of food allergy training for the parents of preschool children and the necessity for food allergy education. Food allergy-related supports, such as menus without allergenic ingredients, guidelines for managing food allergy & anaphylaxis emergency care plan etc, should be provided to the parents in order to avoid events related to food allergies.

Abstract PDF PubReader

OBJECTIVES
This study was conducted to evaluate the nutrition quotient (NQ) by gender and understand which factors influence NQ in preschool children.
METHODS
Subjects were 245 children (110 boys, 135 girls) aged 4-6 years and their parents. The questionnaire composed of demographic characteristics, eating behavior factors and the NQ questions. The NQ consisted of 19 food behavior checklist items and all items were grouped into 5 factors: balance, diversity, moderation, regularity, and practice. Inbody J05, a measurement device that measures individual's body composition was used to measure children's anthropometric data. All data were statistically analyzed by SPSS program (Ver. 20) and the statistical differences in variables were evaluated by Student t-test, chi2-test, One-way ANOVA and Duncan's multiple range test.
RESULTS
The total NQ score of the subjects was 65.3. The NQ score of girls (67.0) was significantly higher than that of the boys (63.2) (p<0.01). The girls' average scores of NQ factors including diversity (p<0.01) and practice (p<0.05) were higher than those of the boys. The analysis of related-factors influencing NQ scores showed that there was a significant difference among the groups according to feeding methods during infancy (p<0.05), breast feeding group being the highest. Furthermore, the NQ score showed a significant difference depending on how to correct children's unbalanced diet as well as parents' nutrition knowledge. The NQ score of obesity group tended to be lower than that of underweight group although there was no significant difference.
CONCLUSIONS
Overall results indicated that the girls had better quality of diet and eating habits than the boys. Children and their parents need proper nutrition education and counseling to correct children's eating habits and to improve diet quality in kindergartens and in children care centers.

Evaluation of Food Behavior and Nutritional Status of Preschool Children in Nowon-gu of Seoul by Using Nutrition Quotient (NQ): Jung Hee Kim, Yeon Hyang Jung; Korean J Community Nutr 2014;19(1):1-11. Published online February 28, 2014; DOI: https://doi.org/10.5720/kjcn.2014.19.1.1

Abstract PDF PubReader

The objectives of this study were to assess food behavior and nutritional status of preschool children by using the Nutrition Quotient (NQ) for children and children's growth index. The subjects for this study were 424, 5-year old children, who enrolled in child-care centers (n = 219) and kindergartens (n = 205) in Nowon-gu, Seoul. The NQ was examined by NQ questionnaire which consisted of 19 food behavior checklist items. Their items were grouped into 5 categories: balance, diversity, moderation, regularity, and practice. Children's anthropometric measurements were performed by using InBody J05. All data were statistically analyzed by SAS 9.3 and significant difference was evaluated by Student's t-test and X2-test. The rates of overweight and obesity for subjects were 11.1% and 3.3%, respectively. Total NQ score of the subjects was 65.1, which was within medium grade. The NQ score of kindergartens (66.1) was higher than that of child-care center (64.2), showing significant difference by institution type. In addition, the NQ score of obesity was significantly lower than that of normal weight subjects. The scores of balance (p < 0.05) and regularity factor (p < 0.001) were higher in kindergarten compared to child-care center. Particularly, the frequency of consumption of white milk and Ramyeon was higher (p < 0.001) and lower (p < 0.05) respectively in kindergarten compared to child-care center. Frequencies of meal regularity (P < 0.01) and breakfast eating (p < 0.001) were also higher in kindergarten compared to child-care center. These results indicate that kindergarten's children had better eating habits than those of child-care center. Overall analysis of items for food behavior checklists implies that children in Nowon-gu are short of vegetables consumption. Therefore, children and their parents need proper nutrition education and counseling to correct their eating habits and to improve their nutritional status.

Factors Related to Calceneal Broadband Ultrasound Attenuation, Anthropometric Indexes and Nutrient Intakes among Elementary School Children in Chungnam: Ye Jung Kim, Yoon Jeong Choi, Hee Seon Kim; Korean J Community Nutr 2013;18(4):312-323. Published online August 31, 2013; DOI: https://doi.org/10.5720/kjcn.2013.18.4.312

Abstract PDF PubReader

Variables affecting bone heath of growing children were analyzed among forty nine 10-12 year old elementary students in three rural regions of north west Chungnam area. Information on age of the parents, duration of breast feeding and birth weight were collected from the guardians of the participants and nutrient intake and diet quality were assessed by average of three-day food records of participants with the help of dietitians. Bone health status was measured by calceneal broadband ultrasound attenuation (BUA) using quantitative ultrasound (QUS). Results showed that anthropometic indexes and nutrient intake levels were not different between boys and girls. However, iron intake was significantly lower in girls than in boys. Girls after menarche showed lower intake levels for thiamin, riboflavin, pyridoxine and niacin than girls before menarche. z-scores of BMI were lower than -1 and higher than +1 showed shorter breast feeding period than others but the difference was statistically non-significant. Overall, the subjects did not consume enough s of calcium, vitamin C and folic acid. Zinc intake and BMI were the most significant factors affecting BUA by the results of backward elimination in multiple regression models. Phosphorous and beta-carotene intakes showed significant negative relation with BUA. This study showed that children living in the rural area of Chungnam need extra care to keep their health and nutrient intakes especially for the nutrients known to affect growth. Tailored nutrition education needs to be more focused on the improvement of bone health status of children.

Implementation and Evaluation of Nutrition Education Programs Focusing on Increasing Vegetables, Fruits and Dairy Foods Consumption for Preschool Children: Su Min Oh, Ye Lee Yu, Hye In Choi, Kyung Won Kim; Korean J Community Nutr 2012;17(5):517-529. Published online October 31, 2012; DOI: https://doi.org/10.5720/kjcn.2012.17.5.517

Abstract PDF PubReader

The purpose of the study was to implement and evaluate a nutrition education program for preschool children. Applying the PRECEDE-PROCEED model, the nutrition education program was developed and focused on changing beliefs, increasing nutrition knowledge and consumption of vegetables & fruits (V/F) and dairy foods. Subjects were children attending a childcare center in Seoulwho were grouped into education (n = 33) and control group (n = 32). Education group received four sessions of nutrition education during 2011 fall. Both groups completed the questionnaire at pretest and posttest, measuring nutrition knowledge, beliefs, and preferences of V/F and eating behaviors. Compared to control group, education group made significant gains in total score of nutrition knowledge after the education (p < 0.05). In addition, the pretest-posttest changes in total score of beliefs regarding V/F consumption and eating behaviors were higher in the education group than in the control group (p < 0.05). Two groups were significantly different in the pretest-posttest changes in specific beliefs regarding the benefits of V/F consumption and some eating behavior. However, there were no changes in the preferences of vegetables or fruits between the two groups after the education. The consumption of V/F and dairy foods was not significantly different after the education. This study revealed that nutrition education for preschoolers was effective in improving nutrition knowledge and perceived benefits regarding V/F consumption and specific eating behavior. This study suggested that more intensive education is needed to induce changes in eating behaviors. This program can be used in nutrition education of children at the childcare centers or kindergartens.

Effects of Fusion-Food Cooking Activity on Elementary School Students' Knowledge, Preferences and Perceptions of Korean Traditional Foods: Jeong Hae Bae, Kyoung Ae Lee; Korean J Community Nutr 2012;17(4):376-389. Published online August 31, 2012; DOI: https://doi.org/10.5720/kjcn.2012.17.4.376

Abstract PDF PubReader

The purpose of this study was to develop a fusion-food cooking program and apply that to sixth grade elementary school students, and to investigate its' effects on their knowledge, preferences, and perceptions of Korean traditional foods. The program focused on ten components. Students learned the general features of Korean traditional foods and Western foods in the 1st lesson. They learnt about kinds, nutrition value, and histories of kimchi, Tteok (rice cake), and Jeon (pan fried food), and cooked two fusion-foods of kimchi, Tteok, and Jeon each. As a result of learning about those food items, the students advanced their knowledge (p < 0.001) of kimchi, Tteok, and Jeon. Their preferences for Tteok (p < 0.05) and Jeon (p < 0.01) were increased, but those for kimchi remained unchanged. The interest (p < 0.05) and preferences (p < 0.01) for the general Korean traditional foods were increased. In conclusion, our results suggested that the fusion-food cooking program had the ability to improve elementary school students' perceptions of Korean traditional foods by increasing their knowledge, preferences, and interest in them. Furthermore it was considered that the program could help students understand the value of Korean traditional foods and in turn may encourage them to consume such food items more frequently. Since the fusion-food cooking activity program can be a good learning program as shown by the results of this study, more fusion-foods cooking activity programs, which are not discussed in this study, should be evaluated and developed in the future.

Effects of Short-Term Food Additive Nutrition Education Including Hands-on Activities on Food Label Use and Processed-Food Consumption Behaviors: among 5th Grade Elementary School Students: Ji Hye Kim, Seungmin Lee; Korean J Community Nutr 2011;16(5):539-547. Published online October 31, 2011; DOI: https://doi.org/10.5720/kjcn.2011.16.5.539

Abstract PDF PubReader

This study evaluated effects of food additive nutrition education on food additives-related knowledge, subjective awareness, and perception and dietary behaviors of food label use and processed-food intake. The study subjects were 5th grade students attending an elementary school in Seoul. A total of 101 subjects were assigned to either education (N = 50) or control (N = 51) group, and 3 food additive nutrition education classes were implemented to the education group. Self-administered questionnaires were collected from all the participants twice, a week before and after the nutrition education to compare the changes between two groups. The food additives-related knowledge and subjective awareness significantly improved in the education group compared to the control group. The changes in perceived harmfulness and perceived necessity for taste were also detected significantly different between the two groups, with more positive changes in the education group. Dietary behaviors of checking food labels and trying to purchase processed-foods with less food additives improved in the education group at a significant level in comparison with the control group. Additionally changes in intake frequency of several processed-food items were significantly different between the groups, again in a more positive direction in the education group. The study findings showed short-term food-additive nutrition education including hands-on activities could positively modify elementary school children's food additives-related knowledge, perception, and certain dietary behaviors, stressing better settlement of in-class nutrition education within an elementary school's education curriculum.

Evaluation of a Nutrition Education Program for 3rd Grade Elementary School Students: Duk Ha Kwon, Sung Nim Han, Hye Kyeong Kim; Korean J Community Nutr 2011;16(2):183-194. Published online April 30, 2011; DOI: https://doi.org/10.5720/kjcn.2011.16.2.183

Abstract PDF PubReader

This study examined the effects of a nutrition education program on nutrition-related knowledge, eating habits, and dietary behavior. Subjects were 3rd grade elementary school students in Anyang, Gyeonggi-do. A 5-week nutrition education program was implemented to 28 children and another 26 children were included in the study as a control group. A self-administered questionnaire was used to assess the effects of nutrition education program. Mean nutrition related knowledge score was improved after education (p < 0.001). There was a significant improvement in knowledge of nutrient source (p < 0.05), role of protein (p < 0.05), food tower (p < 0.001), getting information from nutrition labeling (p < 0.05), and proper way of snacking (p < 0.001). Eating habits and self-efficacy also tended to improve by nutrition education, especially eating habit of snack and self-efficacy on balanced diet reached significant improvement (p < 0.05). Food consumption frequency was not changed significantly, only consumption of sea weeds which is considered as a reluctant food among children was increased after education (p < 0.05). In addition, the number of leftover food items and total amount of leftover at school lunch reduced significantly after education when compared with the same 10-day menu prior to education (p < 0.01). This result suggests that unbalanced dietary behavior has been changed with the nutrition education program. In conclusion, the nutrition education program was found to be effective in improving nutrition-related knowledge, eating habits, and dietary behavior.

Abstract PDF: This study was carried out to examine the effects of nutrition education program developed by Jincheon Public Health Center on preschool children's nutrition knowledge and dietary habits and the parents' dietary attitudes. The subjects of this study were five- and six-year-old children as well as their parents. A 5-week nutrition education program was implemented to 104 children in five day care centers, and 107 children in three day care centers were investigated as a control group. Activity tools designed for each lesson such as puzzles, food magnets, story, songs, Pierrot costume, and balls were used. Nutrition knowledge and dietary habits of children and dietary attitudes of parents were evaluated before and after education. Mean nutrition knowledge score in the education group was significantly higher than that in the control group after education (p < 0.001). Mean dietary habit score of three questions (three meals a day, eating at fixed time, eating breakfast) in the education group was also significantly higher than that in the control group after education (p < 0.01). In addition, parents in the education group showed significantly higher mean dietary attitude score than those in the control group even though they did not receive education (p < 0.001). Our nutrition education program was found to be effective in improving nutrition knowledge and dietary habits in preschool children as well as improving dietary attitudes in their parents.

Evaluation of Nutrition Education for Preschool Children Using Picture-Questionnaire: Saet Byol Hong, Hae Ryun Park, Gyeong Ah Go, Gye Ok Jeong, Kyung Hee Song; Korean J Community Nutr 2010;15(4):475-484. Published online August 31, 2010

Abstract PDF: The purpose of this study was to evaluate the effect of the nutrition education on preschool children's nutrition knowledge and behaviors. The study subjects were preschool children attending J kindergarten located in Wonju. Each of the control group and the education group consisted of 49 children and the education group was exposed to nutrition education while the control group did not. The nutrition education intervention lasted 9 weeks weekly basis. The t-test for the homogeneity of each group showed no meaningful difference at the beginning point of nutrition education. After nutrition education a test of nutrition knowledge using picture-questionnaire was carried out by the researcher for the subjects of education group and control group and the caretakers of the education group were offered self-administered questionnaire on the changes in children's dietary behaviors. The results of the study were as follows: 1. Nutrition education intervention showed a meaningful difference in children's understanding nutrition; the kinds and function of food, the relationship between food and body, the function of nutrients and enhanced their idea on hygiene compared to the control group (p < p.005). 2. However, nutrition education intervention made no statistically meaningful difference in children's dietary behaviors such as having breakfast, keeping balanced diet, washing hands before meals, saying "thanks" before and after meals, cleaning the table after meals, brushing teeth after meals and so on. Therefore, we found that it is hard to expect children to correct their dietary behaviors in such a short period of 9 weeks and nutrition education for preschool children should be offered to caretakers at the same time.

Food Habits, Eating Behaviors and Food Frequency by Gender and among Seoul and Other Regions in Upper-Grade Elementary School Children: Kyung Hee Kim; Korean J Community Nutr 2010;15(2):180-190. Published online April 30, 2010

Abstract PDF: This study was conducted to investigate the differences in food habits, eating behaviors and food frequency by gender and regions in upper grade elementary school children in Korea. Subjects of this study were 1,211 children, 645 boys and 566 girls, attending 6 elementary schools (4th, 5th and 6th graders). 389 children lived in Seoul and 822 children lived in other regions. Mean height, weight and BMI of subjects were 142.4 cm, 38.7 kg and 18.8 kg/m2 respectively. 70.5% of the subjects had breakfast every day and 12.4% of the subjects skipped breakfast. There were significant differences between boys and girls in causes of skipping breakfast, overeating, meal volume, and duration of meals. Girls showed more desirable eating behavior than boys (p < 0.001). Scores for specific eating behaviors such as unbalanced diet and intake of meats and vegetables were better in girls (p < 0.001), and boys ate meals faster than girls (p > 0.001). There were significant differences between Seoul and other regions in eating behavior. Eating behavior scores of children in other regions were higher than in Seoul (p < 0.01). Children in Seoul had a higher frequency of watching television with meals. Frequency of fruits (p < 0.001), milk products (p < 0.01), and meats (p < 0.05) of children in Seoul were higher than other regions. Otherwise the frequency of simple sugar products of children in other regions was higher than Seoul (p < 0.001). Frequency of green vegetables was higher for girls than boys, and frequency of fast foods was higher for boys than girls. These results showed that in nutrition education programs designed to improve the nutritional health of elementary school children, we need to focus more on differences in the children's food habits and eating behaviors by gender and regions. In consideration of these differences, such educational programs need to have a different emphasis for each gender and regions to serve its specific needs.

Abstract PDF: This study was conducted to investigate the body weight status (by WLI: Weight-Length Index) and dietary habits and to assess the nutritional status among preschool children in the Daegu area. Dietary habits including dietary attitude and behavior were investigated using questionnaire answered by mothers of 680 subjects aged 4 to 6 years old (508 completed). Also, dietary intake survey using 24-hour recall method was performed by mothers of the children. According to WLI, the underweight, normal, overweight and obesity level of subjects were 9.1, 62.0, 19.5, and 9.4%, respectively. As well, the number of girls was higher than boys in underweight, overweight, and obese group. There were significantly different on overeating, eating fast, and preferring eating-out by body weight status, and overweight group got higher score than underweight or normal-weight group (p < 0.01, p < 0.001). As well, there was significantly different on not moving around during mealtime by body weight status, and underweight group have lower score than obese group (p < 0.001). From the 24-hour recall survey, it was found that intakes of all the nutrients were higher than the %KDRI except energy, calcium and folate. The energy intake of underweight group of 4~5-year old (1338.2 kcal) and 6-year old was lower than Koreans %DRI for those age group. Folate and dietary fiber intakes of obese group were significantly lower than underweight (p < 0.01, p < 0.05). For 4~5-year old, vitamin B(6) intakes of obese group were significantly higher than obese group (p < 0.05). For 6-year old, obese group showed that intake of vitamin B(1) was significantly higher than the other three groups, and intake of vitamin B(1) of overweight group was significantly higher than the other three groups. Taken together, these results indicate that there were significant differences in the nutrient intake level and dietary habits of preschool children by body weight status in Daegu area. Therefore, parents (family) and caregivers should be aware of the prevalence of obesity and nutritional status of preschool children, and start nutrition education as soon as possible.

Assessment of Physical Activity, Activity Coefficient of Preschool Children and Actual Condition of Daycare Center Outdoor Play: Jae Hee Kim, Eun Kyung Kim; Korean J Community Nutr 2009;14(6):777-788. Published online December 31, 2009

Abstract PDF: The purpose of this study was to assess physical activities and activity coefficient of preschool children and was to give some concrete information to activate outdoor play and to probe the suggestions to activate outdoor play. 42 preschool children (17 boys and 25 girls) were included. Body weight and height were measured and one-day activity diaries were collected by interviewing with their parents and kindergarten teachers. To measure physical activity during outdoor play, this study was researched the current conditions and content of outdoor play activity in daycare centers, and teacher's perceptions of that outdoor play. The average age of the subjects was 5.0 years. Average height, weight, body fat and body muscle of subjects were 108.9 cm, 18.9 kg, 17.7% and 26.8%, respectively. The subjects spent about 10 hours 39 minutes sleeping; 4 hours 16 minutes personal hygiene and computer working. They spent 88.2% of 24 hours (one day) in "very light activities" and 11.3% in "light activities". Activity coefficient (1.34) of weekday was significantly higher than that of weekend (1.21). And in this study, it was found that most of daycare centers (87.7%) have outdoor play space, 95.2% of them were garden. The teachers recognized that have a outdoor play frequency everyday (48%), three or four times (46%) in a week but they have three or four times (38%), one or two times (30%) because of various indoor program. Also, they recognized that have a outdoor play expending time 21- 30 minutes (48%), 31-40 minutes (26%) but they have 21-30 minutes (64%). They answered that have frequency and expending time less than their recognition of outdoor play. Most of daycare center teachers perceived outdoor play to be as important as indoor play, and the teachers believed outdoor play supports children's physical, cognitive, social, and language development. The results of this study may be used to utilize as a basic data for estimate physical activity for preschool children and developed that exercise program to increase physical activity of daycare center outdoor play.

Study of Food Intakes and Eating Patterns among Preschool Children in Daegu Area: Assessment of Dietary Pattern and Dietary Diversity: Ju Young Seo, In Sook Lee, Bong Soon Choi; Korean J Community Nutr 2009;14(5):521-530. Published online October 31, 2009

Abstract PDF: This study was conducted to assess dietary pattern and dietary diversity of preschool children by investigating their food consumption. To accomplish this, dietary intake survey (24 hour-recall food diary) was administered to 508 children aged between 4 to 6 years old from 4 kindergartens in the Daegu area (415 were completed). By using CAN pro 3.0 for professionals, the dietary patterns and dietary diversity scores of each food group were examined by age and sex. Data were analyzed with SPSS 12.0, and chi-square t-test and Anova test, and Duncan's multiple range test used for verifying significance. For 4~5- year-old group, boys had significantly more fruit and meats than girls (p<0.05), but girls had more dairy food than boys with no ignificance. For 6-year-old group, boys had significantly more foods, milk and dairy foods than girls (p<0.05), and also boys had more vegetables and fruit than girls with no significance. For DDS (Dietary Diversity Score), the score of 6-year-old group was significantly higher than that of younger children (p<0.05) and the older the age was, the higher the score was. Dietary Pattern (GMVFD) was verified by 8 types, and the ratio of taking all five food groups (GMVFD = 11111) of the 6-year-old group was 48.8%. Children with older ages had more various foods than younger ones (p<0.05). In addition, the ratio of taking less than the minimal intake of dairy foods of girls (48.1%) was higher than that of boys (41.3%). As results, unbalanced diet, overeating and not eating unbalanced diet were revealed as the problematic dietary habits among preschool children, and those habits may change positively with knowledge on nutrition grow on. Therefore, nutritional characteristics and importance of preschool children should be taught to parents and caregivers, and it must be practical and ready to use in cooking for these children to healthy dietary habits.

Nutrition Knowledge and Eating Behaviors of Elementary School Children in Seoul: Na Young Jeong, Kyung Won Kim; Korean J Community Nutr 2009;14(1):55-66. Published online February 28, 2009

Abstract PDF: This study was aimed to examine nutrition knowledge, dietary attitudes, and eating habits of elementary school students and to examine if their characteristics differ by gender. Subjects were 5th and 6th graders of an elementary school (n = 317) in Seoul, and the survey was done during July 2007. Mean height, weight, BMI of subjects was 148.1 cm. 41.7 kg, 19.0, and 14.3% of subjects were categorized as the overweight/obese group. Anthropometric data were not significantly different by gender. Mean score of nutrition knowledge was 14.9 out of 20 showing moderate knowledge levels, and girls scored higher on nutrition knowledge than boys (p < 0.05). Subjects showed knowledge deficit in areas such as nutrients, food groups and specific weight control information. The percentages of correct answers regarding meals for brain function were significantly higher in girls than in boys (p < 0.05). They got nutrition information mainly from mass media and family/relatives. The mean score of dietary attitudes was 41.2 (possible score: 10-50) indicating somewhat positive attitudes, and the score of eating behaviors was 34.8 (possible score: 15-45). Subjects showed problems in eating habits such as having unbalanced diets and snack foods. 82.6% of subjects had unbalanced meals, and these percentages were higher in girls (87.2%) than in boys (78.1%, p < 0.05). Vegetables and fish/shellfish were the most disliked foods. Specific eating behaviors, such as eating slowly, eating grains and having processed foods less frequently, were better in girls than in boys (p < 0.05). Results also showed that majority of subjects need to improve specific behaviors including having diverse foods, eating meals slowly, having meals at regular times, having adequate foods in each food groups, and eating sweets or salty foods less frequently. Only 52.7% of subjects perceived their body images as normal, and 56.4% had experience of weight control. Reasons for weight control were different by gender (p< 0.05). Based on these findings, nutrition education for school children should focus on modifying eating habits or eating behaviors, by suggesting practically applicable methods and providing nutrition information that is interesting and suitable to school-aged children.

Abstract PDF: This study investigated intake patterns of health functional foods (HFF) in elementary school children and requirements of their parents in the Daejeon area using a questionnaire by 432 parents. Participating parents were composed of female, 83.6% and male, 16.4%. Most of the parents were in their 40's (53.0%) and 30's (45.8%). 47.9% of the children were male and 52.1% were female. The school year of the children was distributed evenly, ranging from the first year to the sixth year. The intake rate of HFF for parents appeared to be 65.3% and for children it appeared to be 63.2%. The primary reason of using HFF to their child was 'For health promotion' (54.4%); the largest reason of non-using HFF was 'Do not feel necessity because is healthy' (48.8%). In regards to purchase place, 'Drugstore' was most selected by 26.1%, while the largest amount of purchase motive was 'Decided by oneself for children's health' (37.7%). The average expense per month was, 'Less than 50 thousand portion' (20.3%). The intake period, 'less than 6 months' was won' for 54.9%. For intake items, 'Vitamin supplementation products' was the largest portion' (20.3%) was indicated. The intake period, 'less than 6 months' was the most selected by 51.3%. Most people (66.7%) selected '1 kind' of intake item. As for intake effect, 45.4% claimed 'A little help'. In regard to experiencing side effects, 'Is not' was 92.7%, however, diarrhea, nettle rash, nausea etc. were a little. The biggest problem of HFF was 'Falsehood/exaggerative advertisement' as identified by 53.1%. For improvement of the HFF system was, 'Verify by more strict formality' as selected by 55.8%. In regards to experience of nutrition education on HFF, 'Is not' was most selected by 51.0%. The most desirous form of nutrition education was, 'Simple paper material' (31.3%). The most desirous content of nutrition education was, 'nutritional management of classified by life cycle' (37.2%). Therefore, HFF must be used properly to promote the health and growth development of children by acquiring scientific and reasonable information about the ability and usage of the food.

Assessment of Daily Steps, Physical Activity and Activity Coefficient of the Elementary School Children in the Rural Area: Hyun Mi Lee, Eun Kyung Kim; Korean J Community Nutr 2007;12(3):361-371. Published online June 30, 2007

Abstract PDF: The purpose of this study was to assess the daily steps, physical activities and activity coefficient of the elementary school children in the rural area. Body weight, height and daily steps were measured and one-day activity diaries were collected by interviewing children. The average age of the subjects was 9.96+/-1.02 years. Average height, weight, obesity index, body fat and muscle of subjects were 136.2+/-8.9 cm, 35.2+/-8.5 kg, 99.6+/-18.8%, 22.9+/-8.5% and 35.8+/-6.0%, respectively. The average daily steps of the subjects was 17,584 and daily steps (19,314) of 3rd grade students was significantly higher than that (15,712) of 5th grade children. But there was no significant difference in daily steps and activity coefficients between boys and girls. Daily steps (23,347) of exercise group showed the significantly higher than that (16,144) of nonexercise group. Gender and grade of subjects did not have significant influence on activity coefficients, but there was a significant difference in activity coefficient on weekdays between the exercise group (1.82+/-0.30) and non-exercise group (1.50+/-0.21). Analysis of variance revealed stronger associations between daily steps and body fat (%) than between daily steps and BMI. Daily steps showed significant negative correlation with body fat (%) measured using two methods r =-0.321 and r = -0.365, respectively. Activity coefficient was significantly correlated (r = 0.436) with daily steps, thus increasing daily steps can prevent and treat childhood obesity by increasing the energy expenditure. The higher activity coefficients (weekday 1.56, weekend 1.53) of the subjects was caused by the fact that rural students spent more time outside and enjoyed stronger activities than urban students. The results of this study can be used to estimate energy requirements for Korean children based on exercise levels and living areas.

Mothers' Perceptions on Preschool Children's Food Preference, Efforts in Improving Food Intake and Their Beliefs in Food Selection: Young Hye Jeong, Jin Sook Yoon, Dong Yean Park; Korean J Community Nutr 2006;11(6):714-724. Published online December 31, 2006

Abstract PDF: In an attempt to investigate mothers' perceptions of factors affecting preschool children's food preferences, their policy improving food intake and belief in food selection, in-depth interviews with 30 mothers who had preschool children were conducted in Daegu and Busan. The interviews were tape-recorded and the contents of interviews were analysed by researchers. Most mothers and children liked meats. It was found that children usually disliked vegetables such as onions, carrots, and green onions. Mothers perceived that many factors affected their children's food preferences: mothers' and fathers' food preferences, food offering at meals, mothers' food intake during pregnancy, children's food intake during weaning period, heredity, peer pressure, and advertisements on television. Mothers made efforts to improve childrens food intakes in many ways: change of cooking method, emphasizing function of nutrients and food for health, conciliation and enforcement, and comparison to other children. The most affecting belief for mothers in food selection was family members' food preference. Health, balance in nutrient intake, degree of food processes, food additives, chemicals, convenience, diversity, and economy were also important beliefs to select food. Convenience was especially the primary belief in choosing and preparing children's snacks. Mothers offered frozen dumplings and meat, instant noodles, tuna, and ham for snacks for convenience. These results showed that mothers understood many aspects affecting children's food preference, tried to improve children's food intakes, and had several beliefs in food selection. We concluded that it is necessary to give information for mothers to make healthy snacks in a short time and chance to learn cooking skills.

The Effect Evaluation of Nutrition Education Program for Preschool Children in Gyunggi-do: Kyung Hee Kim; Korean J Community Nutr 2006;11(5):598-607. Published online October 31, 2006

Abstract PDF: The following study has been conducted by carrying out the nutrition education program for preschool children and measuring the change in their food preference and nutritional knowledge. The 28 boys and 22 girls with the average height of 117.4 +/- 5.1 cm and weight 21.8 +/- 3.5 kg participated in the study. The favorite foods of the children were: meat (51.1%) being the highest, fruits (38.3%), carbohydrates (23.4%), while the least favored food was vegetables (75%). It indicated that 36.2% of the children were having unbalanced diets. The change in food preference after the implementation of the nutrition education program was the significant increase in preference in vegetables and fruits (p < 0.01) and proteins such as meat, fish, eggs and beans (p < 0.05). The differences in food preference among boys and girls were that the boys showed significant increase in vegetables and fruits (p < 0.01) while there was a decrease in the simple sugar groups (p < 0.01). Regarding girls, there were significant increases in vegetables and fruits as well as protein groups of meat, fish, eggs and beans (p < 0.01). The changes in the nutritional knowledge of the preschool children after the implementation of the nutrition education program were scores for the fruits and vegetables group and carbohydrates group showed a significant increase while the scores for the oil and nuts group had decreased considerably. The average score on nutritional knowledge has significantly increased from 9.07 to 10.17 (p < 0.01) and the score on the roles of the nutrients increased from 3.02 to 3.48 (p < 0.05). The changes in eating habits of the children after the nutrition education were the answer for the change in eating habits of the children after the nutrition education was "slight change" 61.4%. Also, the change in food preference was "slight change" 61.4% and the improvement in nutrition education was "slightly" 50%. According to the results of this study, it is evident that the change in eating habits and the acquisition of nutritional knowledge is very difficult, thus requiring consistent and prolonged education. Therefore, it seems to be best to include a more systematic and professional nutrition education program in preschool education. Also, the education for the parents should be implemented since the effect of education on children is greater when it is closely connected with the education at home.

Effect of Mothers' Weaning Attitudes on Their Children's Food Habits and Development: Joo Hee Lee, Changim Kim; Korean J Community Nutr 2006;11(5):551-561. Published online October 31, 2006

Abstract PDF: This study was carried out to evaluate the effect of mothers' attitudes on preparing baby foods for their children's food habits and development. The subjects were allocated to 419 preschool children, aged 3 - 5 years. This study surveyed by questionnaire, which was answered by the children's mothers. Subjects were classified by two groups, active and passive, based on their mothers' weaning attitudes. In the active group, mothers tried to make a variety of foods for preparing the baby foods, whereas mothers in the passive group didn't try to make it too much. Family income was higher in the active group and the subjects' mothers had more jobs than those in the passive group, whereas their parent's education levels showed no differences. According to Rohrer index, 2.6% of subjects were obese in the active group, whereas 7.7% in the passive group. These data were shown significantly different between the groups. There were no differences in mother's food habits and breast-feeding versus formula feeding between the two groups. However, children's food habits were shown statistically different between the two groups. Higher regularity of meals, higher frequencies of snacks at home, higher frequencies of fruit, corn, sweet potato as a snacks and less instant foods were revealed in the active group more than in the passive group. The major problem of children's food habits was an unbalanced diet (52.7%) and the major reasons for unbalanced diet were the taste (58.7%) and the texture (23.2%). The active group used more fruits and vegetables than the passive group. Also there were significant differences to solve problems of children's unbalanced diets. In the positive group, 14.4% of mothers tried to develop new cooking methods for solving the problem of an unbalanced diet, but 8.2% did in the passive group. Furthermore, 2.3% of mothers in the positive group removed unpleasant items of the food, whereas 6.9% did in the passive. The average nutritional knowledge scores on a 10 scale were 7.2 and 6.9 in active and passive groups, respectively, and they were statistically different. Mothers among the active group explained the knowledge for food and nutrition to their children more than those in the passive group. These results suggest that mothers' attitudes for baby food are an important factor for forming their children's food habits. Therefore, it is necessary to develop a nutritional education program, materials and new recipes for a variety of baby foods to mothers.
