The Status of Eating Habits and Nutrient Intakes of Preschool Children in Kyungjoo: Mi Ja Choi, Youn Soo Jung; Korean J Community Nutr 2006;11(1):3-13. Published online February 28, 2006

Abstract PDF: The purpose of this study is to estimate the nutrient intakes and food habits among preschool children in Kyungjoo city. The subjects were 210 preschool children, aged 4-6 years. Measurements of the weight, height, chest circumference, and head circumference of the children were conducted. And general home environment and factors related to eating habits for preschool children were collected using a questionnaire that included information about family income, parents' education and occupations. The average weight-length index (WLI) for the subjects was 103.9%. Using the WLI, 20.0% of the preschool children were underweight, 48.6% were normal, 19.0% were overweight, and 12.3% were obese. On the Rohrer index, 13.8% of the preschool children were underweight, 38.5% were normal, and 47.7% were over weight or obese. The average daily intake (% of RDA) of energy and each nutrient was 1323.5 kcal (81.3%), Ca 484.3 mg (80.7%), Fe 7.05 mg (88.1%), vitamin A 420.0 RE (105%), vitamin B1 0.76 mg (95.0%), vitamin B2 0.87 mg (87.0%), and vitamin C 53.1 mg (106.2%), respectively. In particular, older subjects had lower intake in RDA % of calcium and iron. The energy intake ratio from snacks was much higher than the recommended level of the preschool children. With regard to frequency of regularity of breakfast, 1.9% of preschool children skipped every morning and 7.6% of the children skipped more than 5 per week. With regard to the intake frequency of vegetables, fruits, complex carbohydrates, and milk, 13.3%, 19.9%, 22.8%, and 41.8% of the children ate more than 5 times per week. The eating habit score was positively correlated (r = 0.18, p < 0.05) with household income. This study suggests that nutrition education to increase fruit and vegetable consumption for preschool children should be emphasized. Also a nutrition education program is needed to enhance consuming calcium and iron intake for adequate growth.

Relation among Dietary Habits, Nutrient Intakes and Bone Mineral Density in Korean Normal and Obese Elementary Students: Yun Jung Bae, Eun Yeong Kim, Hye Kyung Cho, Mi Hyun Kim, Mi Kyeong Choi, Mi Kyung Sung, Chung Ja Sung; Korean J Community Nutr 2006;11(1):14-24. Published online February 28, 2006

Abstract PDF: The purpose of this study was to investigate the relation between bone mineral density and nutrient intake among normal and obese elementary students. Each subject was assigned to one of such as normal (n = 69) and obese groups (n = 94) according to their obesity indices. And they were asked for general characteristics, dietary habits and nutrient intakes using questionnaires and 24-hr recall method. They measured the sound of speed (SOS) of calcaneus using quantitative ultrasound. The averages age of the subjects were 10.6 years in normal and 10.7 years in obese group. The averages weight (p < 0.001) and obesity index (p < 0.001) of the normal group were significantly lower than those of the obese group. In dietary habits, the obese group in boys was the higher skipped breakfast than normal group (p < 0.01). The plant calcium intake of obesity in girls was lower than those of normal group (p < 0.05). The SOS in the calcaneus was 1697.6 m/s in the obese group and 1763.7 m/s in the normal group (p < 0.01). The SOS in the calcaneus was negatively correlated to weight (p < 0.01), obesity index (p < 0.001) and percent of body fat (p < 0.01). Also the SOS in the calcaneus was positively correlated plant calcium intake (p < 0.05). In conclusion, the excessive increase of weight and percent of body fat in elementary students appeared to have negative impact to bone health. And based on these results, further studies on the effects on bone mineral density of obese and nutrient intakes in needed for proper bone health.

An Exploratory Study for Identifying Factors Related to Breakfast in Elementary, Middle and High School Students: Bo Sook Yi, Il Sun Yang; Korean J Community Nutr 2006;11(1):25-38. Published online February 28, 2006

Abstract PDF: This study was carried out to identify factors related to breakfasts in elementary, middle and high school students. This study was surveyed by questionnaires and data was analyzed by SPSS program. Exploratory analysis was conducted according to three school student groups (elementary children, middle school students, and high school students). The subjects were 1,886 school students (female 893, male 959) of 51 schools in the nationwide region. The distribution of subjects was elementary school children 544, middle school students 661 and high school students 681. The results are summarized as follows. Only sixty percent of the subjects had breakfast regularly. About one fourth of the subjects had the habit of skipping breakfast or eating it 2~3 times per week. Frequency of having breakfast and reasions of skipping breakfast were significantly different according to school student groups (p < 0.001 respectively). The rate of skipping breakfast was 14.4% in elementary school, 16.1% in middle school, and 25.0% in high school. The main reason for skipping breakfast was "not delicious or poor appetite" in elementary school (42.5%), but "busy" in middle (50.2%) and high school (61.1%). There was no significant difference in frequency of having breakfast according to living areas (rural and urban). There were not significant differences between frequency of having breakfast and BMI and degree of satisfaction on body weight. But there were significant difference in frequency of having breakfast according to economical status (p < 0.05). There were significant differences in degree of school performance according to frequency of having breakfast (p < 0.001). There was significant relationship between the time of attending school and the frequency of having breakfast. But there were significant relationships between frequency of having breakfast and time of rising. These findings suggested that the time of rising was controlled by having enough time that students eat breakfast. And mother (or person who prepares meals) must have more concerns about preparing breakfast for children and students.

The Comparison in Daily Intake of Nutrients, Quality of Diets and Dietary Habits between Male and Female College Students in Daejeon: Mee Sook Lee, Chung Shil Kwak; Korean J Community Nutr 2006;11(1):39-51. Published online February 28, 2006

Abstract PDF: This study was conducted to investigate the differences in daily nutrient intakes, dietary habits and nutrition knowledge between male and female college students. Male undergraduate students (104 subjects) and female undergraduate students (229 subjects), enrolled at H University in Daejeon, were recruited for this study. The mean age of the subjects was 22.9 year in male and 20.4 year in female students. Daily intakes of energy and nutrients were calculated from the records of one day of dietary food intakes by 24-hour recall method, and general information, dietary habits and attitudes, food intake frequency and food preferences and knowledge for food and nutrition were surveyed through a questionnaire. About 70.1% of male and 66.1% of female students were in the normal range of BMI (18.5 - 23), and 25.2% of male students were over-weighted in contrast to 27.7% of female students were underweight. Males and females were taking 77.2% and 77.9% of RDA for energy, respectively, and 54.8% of male and 48.0% of female students were taking energy under 75% of RDA. Many of them showed deficient intakes of calcium, iron, vitamin A and riboflavin. Average of MAR was 0.75 in male and 0.72 in female students. NAR for calcium, iron, vitamin A and riboflavin in male students were 0.55, 0.69, 0.75 and 0.61, respectively, compared to 0.53, 0.51, 0.70 and 0.67 in female students. The nutrients, which have INQ less than 1, were calcium and riboflavin in male, compared to calcium, iron, and riboflavin in female students. There were no gender differences in meal regularity and meal skipping rates, but female students showed higher rates of skipping dinner than males (p < 0.001). About 50.8% of female students were ingesting snacks 1 - 2 time/day, compared to 27.1% of male students. For the food intake frequency, fruit group was significantly eating more for female than male students (p < 0.001). Though female students got higher scores for nutritional knowledge test (p < 0.01) than male students, they did not show better dietary habits or dietary attitudes than male students actually. Therefore, a more active and actual education program accustomed to the different genders and ages with focus on real changing of dietary behaviors needs to be developed and run in schools and local departments.

Dietary Macronutrients and VO2 by BMI among Female College Students in Seoul: Jae Yeon Lim, Hae Bok Na; Korean J Community Nutr 2006;11(1):52-62. Published online February 28, 2006

Abstract PDF: This study was conducted to investigate dietary macronutrient and VO2 by BMI. The subjects consisted of 50 female college students. They were divided into three groups: Below BMI 18.5 kg/m2 (n = 9), BMI 18.5 - 23 kg/m2 (n = 28), above BMI 23 g/m2 (n = 13). Health-related questionnaires, dietary macronutrients, macronutrient compositions, food frequency questionnaires, body compositions and VO2 were studied. Macronutrient compositions that macronutrient intakes were expressed by the percentage of daily energy intakes. There were significant differences in body fat, percent of body fat, and fat distribution by BMI. Also, significantly increasing of basal metabolic rate (BMR) was shown by BMI, but BMR per body weight was decreased by BMI. Overall, there were no significant differences in health-related questionnaires, food frequency questionnaires (FFQ), dietary macronutrients and VO2 by BMI but salty taste preferences and carbohydrate intakes, FFQ of beans, white vegetables rand, yellow-green vegetables in the above BMI 23 g/m2 group were significantly higher than other groups. There were no significant differences in macronutrient composition but the lipid composition of subjects was shown above 20%. Also, energy intakes of subjects were shown to be low; especially the below BMI 18.5 kg/m2 group was very low (55% of RDA). Significantly positive correlation was found in BMR and body composition such as skeletal muscle & lean body mass, but significant correlation was not found in BMR and dietary macronutrients. Overall, researched energy metabolism factor was not different by BMI. Only in the BMI 18.5 - 23 kg/m2 (normal) group, significantly positive correlation was found in VO2peak and body fat oxidation. Therefore, proper nutritional education for female college students is needed in order to improve their obesity-related health. Moreover, a nutritional survey method of finding diverse factors that affect their health should be developed to meet various needs.

Comparison of Nutrient Intake and Antioxidant Status in Female College Students by Skin Types: Hyun Sook Bae, Yunhi Cho, Ju Young Kim, Hong Seok Ahn; Korean J Community Nutr 2006;11(1):63-71. Published online February 28, 2006

Abstract PDF: The objective of this study was to evaluate whether nutrient intakes and serum biochemical indices are associated with the skin condition of humans. Anthropometric data, skin surface hydration, ceramide content, dietary intake of nutrients and serum lipids (total cholesterol, HDL-, LDL-cholesterol, TG, MDA: malondialdehyde, TAS: total antioxidant status) were obtained from 36 healthy young women. Subjects were classified into 2 groups {LM: Low Moisture Group (n = 20), HM: High Moisture Group (n = 16)} by forehead skin hydration. The results of this study were as follows: The average age, BMI, total body water, LBM, body fat%, WHR, forehead hydration, ceramide content were 20.2 yrs, 20.7, 28.8 l, 39.2 kg, 28.0%, 0.8, 44.3%, and 1.05 microgram/microgram protein, repectively. The intakes of SFA (saturated fatty acid), MUFA (monounsaturated fatty acid) in the HM group were significantly higher (p < 0.05) than in the LM group, but zinc intakes in the LM group were higher than in the HM group. Serum levels of TAS in the LM group (1.27 mmol/l) were significantly higher (p < 0.05) than that of in the HM group (1.20 mmol/l). Whereas other lipid levels were not significantly different, intakes of vitamin B6 and folate showed significant positive correlation with the forehead hydration (r = 0.447, r = 0.377). Intakes of calcium and phosphorus showed significant negative correlation with forearm ceramide content (r = -0.496, r = -0.485). Several associations between nutrient intakes and skin conditions were observed, indicating that changes in baseline nutritional status may affect skin health.

A Study on Body Compositions and Food Behaviors of Middle Aged Men Living in Jeonbuk Province by Percentage of Body Fat: Hye Soon Chang, Mi Ra Kim; Korean J Community Nutr 2006;11(1):72-82. Published online February 28, 2006

Abstract PDF: The purpose of this study was to compare the body compositions and food behaviors of middle aged men with different obesity indices. The subjects were 62 middle aged men who lived Gunsan city. Heights, body weights, soft/lean masses, fat masses, percentages of body fat, and fat distributions were measured. Food habits and health-related lifestyle habits were evaluated based on questionnaires. The subjects were assigned to one of the following groups based on their percentage of body fat (%Fat); normal, overweight and obesity. The results were as follows: their heights, fat masses, percentages of body fat, WHR, RBW, BMI and fitness scores were significantly higher in the obese subjects when compared to the normal and overweight subjects. Self-perceptions of weight and desires of weight control were significantly related with their percents of Fat. The overweight and the obese groups skipped meals, ate supper out, ate snacks, smoked tobacco, and exercised less frequently than the normal group. There were no significant differences in the scores of the dietary habits and drinking of alcohol among the three groups. Therefore, proper nutritional education on regular meals and intervention is required if middle aged men want to be of normal weight and have healthy lifestyles.

A Study on the Dietary Habit in Residents of Rural District Muan of Chonnam: Bok Mi Jung, Yoo Hyang Cho, Hae Ok Jung; Korean J Community Nutr 2006;11(1):83-97. Published online February 28, 2006

Abstract PDF: This study was to investigate dietary habit for residents in the rural area of Chonnam, Muan. The subjects were composed of 61.2% male and 38.3% female (510 adults). In regularity of meal time, 56.3% of the subjects had meals regularly. The older people were significantly higher than the younger people at regular intervals of meal times (p < 0.0001). The majority of the subjects had appropriate meal amounts. 73.5% of the subjects had balanced diets. Unbalanced diet was higher in younger people than in older people. The highest frequency to dining out was once a month and the lower age was significantly higher than older age (p < 0.001). When dining-out, the most important criteria for selecting a meal was the taste of food. 62.4% of the subjects ate meat and greasy animal food more than once a week. The younger in age and higher in educational levels have increased meat intake frequency. In the eating methods of animal fat, 37.5% of the subjects were high by eating generally untouched. The older in age, lower in education level have more increased animal fat intake frequency. 60.7% of the subjects took snacks. The kinds of snacks were fruits, coffee, alcoholic drinks, candies and confectioneries, drinkables and tea, milk and dairy products, in order. Consequently, nutrition education is for them with special emphasis on regularity of meal times, unbalanced diets, dining-out and snacks to the younger people, whereas it is the necessary eating methods of animal fat and snacks to the older people.

Food Preference Test of the Korean Elderly Menu Development: Seon Joo Park, Hae Jeung Lee, Wan Soo Kim, Jae Yeon Lim, Haymie Choi; Korean J Community Nutr 2006;11(1):98-107. Published online February 28, 2006

Abstract PDF: This study was performed to test food preferences of the Korean elderly for Korean elderly menu development. The elderly subjects preferred steamed rice cooked with 1.2 times water than that with 1.5 times water (p < 0.001), whole rice grain gruel than the gruel with ground grain (p < 0.05). Green tea powder gruels developed as a snack, there were no significant differences in the preference of the elderly between gruel with different contents of green tea powder (2, 3, 4%). The preferences of the salt concentration of the soup were tested by using soybean sprout soup and soybean paste soup. The elderly preferred 0.7 - 0.8% salted bean sprout soup and 7% soybean paste soup. The elderly preferred Kimchi cut in widths of 1 - 2 cm than that in 0.5 cm. The elderly preferred sweeter grape jam (67% vs. 50% or 37% sugar content) and were not concerned about chewing seeds. This result could be useful to develop menus for the elderly.

Effect of Nutrition-Related Education on the Acceptance of TV Food Advertisement in Middle School Students: Hae Ran Ko, Myoung Soon Park, Mi Young Song, Joung Won Lee; Korean J Community Nutr 2006;11(1):108-115. Published online February 28, 2006

Abstract PDF: This study was to investigate the effect of the education about general nutrition knowledge on the acceptance of TV food advertisements in adolescents. Twenty hours of nutrition related education in home economics classes were done during 3 months, to conveniently selected 784 first grade middle school students living in large and small cities and rural areas of Chungnam Province. The education effects were evaluated through questionnaire surveys before and after the education and their comparative analysis. Average TV watching time was 2.92 +/- 1.66 hours per day, which was about one hour longer on weekends. Nearly half of the subjects watched TV mainly after 9 PM. After nutrition education, nutrition knowledge scores of total subjects were significantly increased from 7.73 +/- 2.16 to 10.25 +/- 2.51 with a full score of 16. Food attitude and food habit scores also significantly increased from 32.45 +/- 4.65 (full score 50) to 33.93 +/- 4.68 and from 36.20 +/- 5.70 to 37.29 +/- 5.87, respectively. The general acceptance of TV food advertisements scored 25.25 +/- 4.44 (full score 40) before education and 26.90 +/- 4.55 after education, which was significantly raised by the education. Acceptance scores of TV food advertisements showed significant positive relationships with the scores of nutrition knowledge, food attitudes, and food habits. In addition, TV watching time had negative relationships with nutrition knowledge, food attitudes, and food habits scores, but not with acceptance score of TV food advertisements. The above results suggested that school-based nutrition education improved slightly but significantly the attitude of accepting TV food advertisements maybe through increasing nutrition knowledge and making food attitudes and habits better. Nutrition education focused on the evaluation and acceptance of food advertisements are further needed to improve the TV food advertisement acceptance of adolescents.

Development of Internal Branding Performance Measure and Analysis on the Difference of Internal Branding Performances between Local and International Hotels: Mi Kyung Choi; Korean J Community Nutr 2006;11(1):116-123. Published online February 28, 2006

Abstract PDF: The purposes of this study were to develop a tool for assessing internal branding performance and to identify the difference of internal branding performance between local and international hotels. The internal branding performance measure was developed through literature studies and face-to-face in-depth interviews with managers in various departments of 5 deluxe hotels. The questionnaires were distributed to 460 employees in food and beverage departments of 11 deluxe hotels in Seoul, and a total of 398 questionnaires were used for analysis (86.5%). The statistical analyses were completed using SPSS Win (12.0) for descriptive analysis, reliability analysis and t-test, and AMOS (5.0) for confirmatory factor analysis. The results of this study showed that the measure developed in this study was reliable and valid for assessing internal branding performances of hotels. In addition, the internal branding performances of hotels were high at understanding of brand dimensions and relatively low at work and organizational culture and human resource management dimensions, and local hotels showed lower levels of performance than international hotels at the dimensions of work and organizational culture (t = -3.801, p < 0.001) and human resource management(t = -5.397, p < 0.001). In conclusion, it is considered that a strong internal branding strategy should be established for successful brand management, and the practical measure for internal branding performance would be a key factor.

Effects of the APACHE III Score, Hypermetabolic Score on the Nutrition Status and Clinical Outcome of the Patients Administered with Total Parenteral Nutrition and Enteral Nutrition: Miyong Rha, Eunmi Kim, Young Y Cho, Jeong Meen Seo, Haymie Choi; Korean J Community Nutr 2006;11(1):124-132. Published online February 28, 2006

Abstract PDF: The aim of this study is to evaluate the clinical outcome. Between January 1, 2002 to September 30, 2002, we prospectively and retrospectively recruited 111 hospitalized patients who received Enteral Nutrition (ENgroup n = 52) and Total Parenteral Nutrition (TPNgroup n = 59) for more than seven days. The factors of clinical outcomes are costs, incidences of in-fection, lengths of hospital stay, and changes in weight. The characteristics of patients were investigated, which included nutritional status, disease severity (APACHE III score) and hypermetabolic severity (hypermetabolic score). Hypermeta-bolic scores were determined by high fever (>38 degrees C), rapid breathing (>30 breaths/min), rapid pulse rate (>100 beats/min), leukocytosis (WBC > 12000 mm3), leukocytopenia (WBC < 3000 mm3), status of infection, inflammatory bowel disease, surgery and trauma. There was a positive correlation between hypermetabolic score and length of hospital stay (ICU), medical cost, weight loss, antibiotics adjusted by age while APACHE III score did not show correlation to clinical outcome. Medical cost was higher by 18.2% in the TPN group than the EN group. In conclusion, there was a strong negative correlation between the clinical outcome (cost, incidence of infection, hospital stay) and hypermetabolic score. Higher metabolic stress caused more malnutrition and complications. For nutritional management of patients with malnutrition, multiple factors, including nutritional assessment, and evaluation of hypermetabolic severity are needed to provide nutritional support for critically ill patients.

Effects of Antioxidant Supplementation on Lipid Profiles in Elderly Women: Jae Yeon Lim, Ok Hyun Kim, Jung Hee Kim; Korean J Community Nutr 2006;11(1):133-142. Published online February 28, 2006

Abstract PDF: Antioxidant vitamin supplementation focuses one's attention on the prevention of age-related diseases. This study was conducted to investigate the antioxidant status and lipid profiles and to look into the antioxidant vitamin supplementation that affects lipid metabolism in 20 elderly non-smoking Korean women (placebo group: n = 6, vitC suppl: n = 7, vitE suppl: n = 7). Age, height, weight, muscle, percent of fat and WHR were not significantly different among the groups, however % of fat was above 33% and WHR was above 0.9. And blood pressure of the placebo group was 131.7/81.7 (border line hypertension), that of vitamin C supplement was 141.4/87.1 (hypertension) and that of vitamin E supplement was 151.4/92.9 (hypertension). Although nutrient intakes of all groups were poor, antioxidant status (blood vitamins C, E, A, and beta-carotene) and lipid profile (TG, total-cholesterol, VLDL-cholesterol, LDL-cholesterol, HDL-cholesterol) were normal. For nutritional intervention, the vitamin C supplement group received L-ascorbic acid 1,000 mg, and vitamin E supplement group received d-alpha-tocopherol 400IU for 4 weeks, showing the effects of vitamin E supplementation. Response total cholesterol of HDL-cholesterol (T-Chol/HDL) in vitamin E supplement group was significantly decreased from 4.3 to 3.2. And response LDL-cholesterol of HDL-cholesterol (LDL/HDL) in the vitamin E supplement group was also significantly decreased from 2.6 to 1.7. In addition, after the adjustment for plasma lipids (TG, total cholesterol), plasma vitamin A levels in vitamin E supplement group were significantly increased from 7.89 mg/g to 14.91 mg/g. And systolic blood pressure in vitamin E supplement group was significantly reduced. These results suggested that vitamin E supplementation affects the lipid profiles and blood pressure in elderly non-smoking women. So various nutrition programs must be implemented against age-related diseases and further studies are needed regarding sorts and amounts of antioxidant nutrients and supplementation periods.

The Effect of Combined Training at Different Times of Day on Body Composition, Plasma Lipids, Stress Hormones and Nutrient Intakes: Kyoung Young Lee, Si Young Kim, Tae Won Jun; Korean J Community Nutr 2006;11(1):143-151. Published online February 28, 2006

Abstract PDF: Regular exercise training improves body composition, blood lipid profiles and exercise adaptation. This study was conducted to investigate the effect of exercise training at different times of day on body composition, blood lipids, stress hormones and nutrient intakes. Twenty four male graduate students carried out this experiment. The subjects were divided into three groups; morning exercise group, evening exercise group and control group. Two exercise groups performed running and muscular resistance training at mid intensity for 12 week periods. Body composition, blood lipid profiles, blood cortisol, ACTH and nutrient intakes were analyzed prior to, midway and after training. There were significant differences about interaction between different exercise times and training periods in plasma TG and HDL-C of the evening exercise training (p < 0.05). Also the evening exercise group was showed the decreasing of TC after training (p < 0.05). No significant differences about interaction between different exercise times and training periods were shown in body composition, stress hormones and nutrient intakes in the three groups. But evening exercise training decreased body fat (%) and blood ACTH (p < 0.05). Also the increasing of carbohydrate intakes was shown by the evening exercise training (p < 0.05). In contrast, morning exercise group indicated a decrease of body fat (%) after 6 week training (p < 0.05), but this effect was not maintained after 12 weeks of training. These results suggested that regular evening exercise is more effect than morning exercise from the viewpoint of improving body composition, blood lipids, nutrient intakes and exercise adaptation.
