Relationship between Dietary Behaviors and Life Stress of Middle School Students in Gyeonggi Area: Kyung Ae Park, Myoung Sook Lee, Kyung Hee Song; Korean J Community Nutr 2019;24(5):384-394. Published online October 31, 2019; DOI: https://doi.org/10.5720/kjcn.2019.24.5.384

OBJECTIVES
The study was performed to examine the dietary behaviors and life stress of middle school students in the Gyeonggi area.
METHODS
A total of 580 middle school students (295males, 285 females) in the Gyeonggi area participated in the study between July and August in 2011. The study was a questionnaire-based survey that included dietary habits, dietary behaviors, and life stress.
RESULTS
For dietary habits, the score for drinking milk was higher in male students than in female students, whereas the score for eating fruits was higher in female students compared to male students. There were significant differences in foods eaten and preferred under stress between male and female students. Male students showed significantly less changes in the number of meals, amount of meal intake, number of snacks, snack intake, frequency of overeating, and appetite during stress than female students. Life stress score of students largely came from academic factors, and female students showed higher stress levels in personal and surrounding environment factors than male students. Life stress score was significantly lower in students with high and moderate levels of dietary habits than in students with a low level of dietary habits. Total score for dietary habits and scores for eating adequate amounts of foods for each meal, considering a combination of food groups at each meal and eating green and orange vegetables, were significantly negatively correlated with life stress score. Life stress score was significantly negatively correlated with meal regularity and positively with the level of overeating.
CONCLUSIONS
This study may provide basic information on dietary habits and life stress according to gender and the relationship between dietary behaviors and life stress of middle school students, and it suggests gender-based nutrition education programs to solve undesirable dietary habits and dietary behaviors in students with higher stress.

OBJECTIVES
The rapidly changing dietary environment requires a study that addresses the status of middle and high school students regarding their consumption of convenience food sold at convenience stores.
METHODS
This study examined adolescents' lifestyle patterns, dietary habits, and status of consuming convenience food at convenience stores. A total of 659 students (329 middle school students and 330 high school students) in Incheon participated in this questionnaire survey.
RESULTS
The mean age of the subjects was 13.7 years for the middle school students, and 16.6 years for the high school students. The gender and grade distributions in the middle and high school students were similar. The middle school students reported that they spent more time using electronic devices (p<0.001) or watching TV (p<0.001) than high school students. More than 60% of middle and high school students consumed convenience food at convenience stores without statistical difference between the two groups. The main reason for consuming convenience food from convenience stores was its convenience followed by taste in both groups. Despite the high frequency of consuming convenience food, the students rarely checked the nutrition labels at the time of purchase. On the other hand, they were still most concerned about the nutritional value of the convenience foods when they consumed convenience foods. The most frequently consumed convenience food was ramyon in both groups. Significant positive correlations were observed between the frequency of consuming convenience food at convenience stores and lifestyle factors for the middle school students, including monthly allowance, time for using electronic devices, and number of private lessons. For the high school students, however, the only monthly allowance had a significant positive correlation with the consumption.
CONCLUSIONS
Adolescents are increasingly exposed to convenience foods and relevant nutritional issues are a concern. Therefore, a dietary environment that is adequately formed for the healthy development of youth as well as systematic nutrient education that is appropriately designed for both middle and high school students is required.

Abstract PDF PubReader: OBJECTIVES
The study was performed to investigate the relationship between snack intake and oral health behavior in middle school students in Gyeonggi-do area.
METHODS
The survey questionnaire was recorded by middle school students from July 6 to August 24, 2011. The questionnaire included items on general characteristics, snack intake status, and oral health behavior. Among collected survey questionnaire, a total of 620 questionnaires (320 males and 300 females) were analyzed using SPSS 15.0 program.
RESULTS
Frequencies of snack and beverage intakes were significantly higher in males than in females (p < 0.001). Oral health behavior was significantly higher in students with lower snack intake compared to those with higher or average snack intake (p < 0.05). Oral health behavior for tooth brushing and toothbrush care were significantly higher in females than in males (p < 0.05).
CONCLUSIONS
Oral health behavior score that reflected better oral health of the subjects were higher as the snack intake was lower. Oral health behavior score was higher in females than in males. We conclude that the contents for oral health and nutrition education focused on snack intake need to be developed to induce changes in oral health behavior in middle school students.

Survey on Foodservice Satisfaction and Dietary Education needs for Improvement of School Foodservice in Middle School Students in Seoul: Kyung Hee Shin, Youngmee Lee, Wookyoun Cho; Korean J Community Nutr 2017;22(2):127-135. Published online April 30, 2017; DOI: https://doi.org/10.5720/kjcn.2017.22.2.127

Abstract PDF PubReader

OBJECTIVES
This study was conducted to examine the satisfaction of school cafeterias among the surveyed group at two middle schools located in Seoul.
METHODS
574 out of 600 middle school students in Seoul (95.7%) completed the study.
RESULTS
Satisfaction rate of school meals was significantly higher among girls (73.2%) compared to boys (45.1%). The reasons for satisfaction factors of school meals were with the taste of school meals (55.1%), menu (19.3%), nutrition (14.2%), and food hygiene safety (7.0%). Students who had a double-income family, well-educated mother and higher happiness in their life reported a higher satisfaction with school meals. Both boys and girls who consumed milk frequently showed significantly higher satisfaction with school meals. Factors that were related to satisfaction of school meals were food temperature, the amount of food (especially among boys). Variety in the menu and food distribution speed were less related to the satisfaction of meals. In the case of girls, waiting time, food distribution speed were more important to them while the kindness of school staff was a less important factor. Improvements that were needed to increase the satisfaction for the school lunch meals, from the most important to least important were as follows: variety of meals (36.6%), food distribution speedÂ·waiting time (24.6%), taste of food (15.7%), amount of food (7.7%), hygienic management (5.1%), food quality (4.7%), kindness (3.0%), temperature of the food (2.8%). Students preferred to broadcast on campus and cooking practice for the dietary education.
CONCLUSIONS
To improve school meal satisfaction, it is necessary for food distribution facilities to make improvements with regard to variety of meals and reduced waiting time.

The Influence of Self-resilience on Dietary Management in Middle School Students: Yunhwa Kim; Korean J Community Nutr 2015;20(6):399-410. Published online December 31, 2015; DOI: https://doi.org/10.5720/kjcn.2015.20.6.399

Abstract PDF PubReader

OBJECTIVES
This study aims to identify self-resilience factors that drive right dietary and food safety practices in middle school students.
METHODS
Data was collected from 438 middle school students in Daegu using a self-administered questionnaire in December, 2013. The questionnaire consisted of 81 items with the following categories: general information, self-resilience, right dietary and food safety practices. Statistical analyses to determine frequency, average, ANOVA, factor analysis, reliability analysis, and regression analysis were performed using SPSS 21.
RESULTS
The results of factor analysis indicated that self-resilience was classified into challenge, adaptability, patience and achievement needs, and right dietary practices were sub-grouped into family meals, experience of dietary life, eco-friendly, balanced food, economy and bad food control, and food safety practices consisted of management of bacteria, hand washing and eating off a plate, safety food and food purchasing. The score of right dietary and food safety practices showed significant differences by sex, grade, and school achievement (p < 0.05). The economy factor of right dietary practices was significantly affected by the management of bacteria (p < 0.001), hand washing and eating off a plate (p < 0.001), safety food (p < 0.01), food purchasing of food safety practices (p < 0.05). The challenge factor of self-resilience significantly affected family meals, experience of dietary life, balanced food, economy, bad food control, management of bacteria, hand washing and eating off a plate, and safety food (p < 0.05). The adaptability factor of self-resilience was associated with factors such as eco-friendly, balanced food, economy, bad food control, management of bacteria, hand washing and eating off a plate, and food purchasing (p < 0.05).
CONCLUSIONS
This study suggests that dietary education programs for middle school students could incorporate food safety practices, and self-resilience such as challenge, adaptability, patience and achievement needs to be effective.

A Comparison of Dietary Habits, Weight Control Behaviors, Eating Disorder Risk, and Depression of Middle School Girls according to Various Stages of Dieting: Aekyung Jung, Hyunsuk Ryu, Kyunghee Song, Hongmie Lee; Korean J Community Nutr 2015;20(3):178-187. Published online June 30, 2015; DOI: https://doi.org/10.5720/kjcn.2015.20.3.178

Abstract PDF PubReader

OBJECTIVES
This study was conducted to compare dietary habits, weight control behaviors, eating disorder risk and depression among middle school girls who were at various stages of dieting.
METHODS
Subjects were 391 girls attending a middle school in Kyeonggido, Korea. All the information was gathered by self-administered questionnaires. Eating disorder risk and depression were assessed using EAT-26 and PHQ-9, respectively. Data were compared among 4 groups; no interest in a diet (N=112), had experienced dieting (N=86), on diet currently (N=71), and plan to diet (N=122).
RESULTS
A higher number of students currently on diet tended to be unsatisfied with their own weight (p < 0.01), overestimated their weight (p < 0.05), and weighed own body frequently (p < 0.001), compared to those with only experienced dieting in the past or those who plan to diet, despite similar weights and body mass index. The students who experienced dieting in the past or those who plan to diet appeared to have several undesirable as well as desirable dietary habits and their risk of eating disorder was significantly more prevalent compared to those without an interest in dieting (p < 0.01), although significantly less prevalent compared to those currently on a diet.
CONCLUSIONS
We conclude that unnecessary dieting is common among middle school girls and providing proper education with regard to healthy weights is needed to enhance their physical as well as psychological wellbeing.

Middle School Students' Perception of Environment-friendly Agricultural Products (EAPs) and the Degree of Confidence about the Certification Mark in Daegu: Ji Yeon Jang, Mi Kyung Choi; Korean J Community Nutr 2013;18(4):324-332. Published online August 31, 2013; DOI: https://doi.org/10.5720/kjcn.2013.18.4.324

Abstract PDF PubReader: The purpose of this study was to investigate middle school students' perception of environment-friendly agricultural products (EAPs) and the degree of confidence about the certification mark. Questionnaires were distributed to 444 students of 6 middle schools located in Daegu, and a total of 416 responses were used for analysis. 28.6% of the respondents were using EAPs at home, and 62.0% of respondents didn't know whether to use EAPs at home. The 6 items representing the perception of EAPs were analyzed, resulting in 2 distinct dimensions-'benefits of EAPs' and 'attitude toward EAPs'. Regarding Benefits of EAPs, the score of 'EAPs better for health' was the highest, followed by 'EAPs have higher quality', 'EAPs were better for environmental protection', respectively. The proportion of students responded that 'the amount of pesticides should be reduced gradually' was 65.5% and only 3.4% for 'current level of pesticide use is not a problem'. There were significant differences between male and female students with regard to an interest in EAPs (p < 0.05) and opinion on the use of pesticides (p < 0.05), while no significant difference was found between groups with different education level of mothers. The respondents who use EAPs at home showed significantly higher scores with attitude toward EAPs (p < 0.001), and higher response rate for 'pesticides should not be used even if the price increases' (p < 0.05). Degree of confidence about the EAPs certification mark also affected students' perception of EAPs (p < 0.001). Our results indicate the importance of education for students on EAPs to enhance students' attitude towards EAPs and improve school meal satisfaction.

A Study on the Correlation between Middle School Students' Eating Disorder Behavior and Scholastic Adjustment: Joo Yeon Yoo, Yang Ho Jin, Se Jeong Bae; Korean J Community Nutr 2012;17(6):707-713. Published online December 31, 2012; DOI: https://doi.org/10.5720/kjcn.2012.17.6.707

Abstract PDF PubReader

The purpose of this study was to verify the difference of middle school students' eating disorder behavior and scholastic adjustment according to the gender and weight group and evaluate correlations between their eating disorder behavior and scholastic adjustment. A survey was conducted in middle school second graders attending five schools located in Seoul. Results from 355 questionnaire sheets were utilized for statistical analysis, and the results were gained as below: With regard to eating disorder behavior by gender, female students showed more eating disorder behavior than male students (p < 0.01); however, scholastic adjustment did not indicate significant differences by gender. According to the result of analyzing scholastic adjustment according to the weight group, the obese group showed lower scholastic adjustment (p < 0.05) and adjustment to studying (p < 0.01) than other groups; however, the eating disorder behavior, attachment to school, and adjustment to school did not indicate significant differences. According to the results of analyzing scholastic adjustment by eating disorder group, the normal group showed higher adjustment to studying than the risky group (p < 0.01). And scholastic adjustment, attachment to school, and adjustment to school did not indicate significant differences. The eating disorder behavior showed negative relationship with adjustment to studying. They showed more eating disorder behavior, their adjustment to studying became lower. Therefore, it is necessary to provide nutritional education at home and at school for them to have appropriate dietary habits as well as health education for them to maintain normal weight.

A Study on Vegetable Intakes and Dietary Habits of Middle School Students in Chungnam: Hyun Sun Cho, Myung Hee Kim, Mi Kyeong Choi; Korean J Community Nutr 2010;15(4):525-535. Published online August 31, 2010

Abstract PDF: The purpose of this study was to provide basic data for nutritional education for juveniles' desirable vegetable intake by analyzing their vegetable intake, dietary habit and nutrient intakes according to gender of middle school students in Chungnam. The average age of the subjects was 15.0, height was 162.5 cm, weight was 53.5 kg and their average BMI was 20.1 kg/m2. The frequency of eating supper in girls was lower than that in boys. Many respondents answered that a meal-time was 10~20 minutes. Without gender difference, more than 90% respondents thought that vegetables were good for health. As for the preference of vegetable, subjects responded, "I am in the middle", "I like them", "I dislike them", "I like them very much", and "I dislike them very much" in order, without gender difference. The frequent eaten leaf vegetable was Chinese cabbage, the frequent eaten fruit vegetable was cucumber, and the frequent eaten root vegetable was radish. The favorite leaf vegetable was lettuce, the favorite fruit vegetable was corn, and the favorite root vegetable was sweet potato. The preference degrees of taro and ginger were very low. The reasons why they liked a vegetable were that it was delicious and they ate it at home often. In addition, the reason why they disliked vegetables was that they are untasty in flavor or texture and it showed that many students had a prejudice that vegetables were untasty. The intakes of plant protein, dietary fiber, ash and INQs of dietary fiber, calcium, vitamin C, folate, vitamin E in the group with high preference of vegetables were significantly higher than those of low preference group. The study results indicate that intake frequency and preference of root vegetables in juveniles are low and the major reasons of these results are taste and eating experience of vegetables. In addition, the intake amounts of dietary fiber and folate are poor in the subjects with low preference of vegetables. Therefore, families and schools should make efforts that juveniles can recognize the importance of vegetable intake and select various vegetables properly through the development of cooking methods and systematic nutrition education.

A Study on Middle School Students of Gwangju, Chonnam in Terms of Dietary Life, Dietary Related Self-efficacy According to Body Mass Index: Hyun Hwa Kim, Hee Kyong Ro; Korean J Community Nutr 2009;14(5):483-494. Published online October 31, 2009

Abstract PDF: In order to give basic data to teenager's healthcare, we investigated the food habits according to BMI (Body Mass Index), life style, dietary related self-efficacy and food intake through conducting a research surveying 732 middle school students of the Kwang-ju and Chonnam areas. The results of this study were compared groups in under weight (UW), normal weight (NW), and overweight (OW) groups according to BMI levels. In the male students, height was significantly differently in the UW group as 158.2 +/- 0.7 cm compared to other NW and OW groups respectively as 163.7 +/- 0.6 cm and 162.6 +/- 0.7 cm but in the female students there was no significantly difference within groups. Weight was significantly different between the groups in the male students, whereas there were minor differences in the female students. The average of BMI was 20.7 +/- 0.1 on the male students and 20.6 +/- 0.1 on the female students which were all within the average, and their obesity was increased as the school grade was higher. Under less than 30,000 won of pocket money was dominating, and most of the students were in a nuclear family. In all male and female students, the inactive hours like watching TV and using computers had no differences between groups. The difference between groups was minor on breakfast time and most of the students thought their problems on unbalanced diet. There was significant difference in the OW group in female students as they thought their problems on unbalanced diets. The frequency of snack was significantly low in the OW group of male students but there were no differences in snack and eating-out food. All students chose fruits as snack food and Korean-style food as eating out food. The OW group in male students were significantly low in the dietary related self-efficacy when they were with their families and feeling depressed but there were no differences in female students between groups. When all students were getting higher BMI, they evaluated themselves badly in their self-dietary habits. Also the more male students had non-physical activity time, the less they had the dietary related self-efficacy and the more female students had physical activity time, the higher they had the dietary related self-efficacy. In conclusion, the OW group had good habits in physical activities for weekends, meal times, frequency of snack consumption but it showed undesirable when they were low in dietary related self-efficacy. Therefore we will provide the systematic nutrition education to them through this study.

Snacking Behaviors of Middle and High School Students in Seoul: Seul Ki Choi, Hyeon Jeong Choi, Nam Soo Chang, Sung Hee Cho, Young Sun Choi, Hye Kyung Park, Hyo Jee Joung; Korean J Community Nutr 2008;13(2):199-206. Published online April 30, 2008

Abstract PDF: The purpose of this study was to investigate snacking behavior in adolescents. We selected one middle school and one high school in 11 school districts in Seoul. The subjects were 1,813 students (904 boys and 909 girls) in 21 schools (11 middle schools and 10 high schools). Subjects reported their snacking behavior: snack frequency, snack type, snack time, with whom to eat snack, place to purchase snack. The subjects were classified into four groups by gender and schooling. The mean snack frequency was 2.8. Girls ate snacks more frequently than boys (p < 0.001). More than half of subjects ate 1 to 3 snacks a day. Only 9.3% of them did not eat any snack. Tangerine was highly ranked in snack type. Each subject groups had different snack time (p < 0.01) and type of snack (p < 0.001). Most snack was consumed alone (46.6%), however they mainly ate fruits and other foods with family. 46.9% of snacks were purchased outside. A typical snack time was 'before dinner' for most snacks except fruits. Unhealthy foods like soft drinks, cookies, chips, candies, chocolates, ice creams had relatively high proportion in snack consumption with friends. In conclusion, adolescents had different snacking behaviors by their age and gender. These results indicate necessities of multi-dimensional efforts at home, school, media and government level considering adolescents' age and gender for their healthy snacking behavior.

Weight-related Perceptions, Practices and Eating Behaviors of Middle School Students: Associations with BMI: Ji Eun Kim, Hye Sun Min; Korean J Community Nutr 2008;13(1):13-23. Published online February 29, 2008

Abstract PDF: This study investigated the association between the weight status of middle school students and the various weightrelated characteristics including desired weight, weight perception, weight-related practice, physical activity, and overeating behavior. Questionnaires were administered to 473 middle school students (178 boys and 295 girls) in Daejeon. Boys and girls were divided into three groups respectively; (1) underweight (BMI < 5th percentile) (2)normal weight (5th percentile < or = BMI < 85th percentile) (3) overweight (BMI > or = 85th percentile). Using BMI calculated from measured height and weight, 14.0% of boys and 6.8% of girls were underweight, and 16.3% of boys and 14.2% of girls were overweight. However, among this sample of students, 38.4% of boys and 13.6% of girls perceived themselves as underweight and 29.4% of boys and 44.9% of girls perceived themselves as overweight. We found that overweight students reported their body weights lower and their heights higher compared to nonoverweight students, resulting in an underestimation of BMI. Based on desired BMI, 79.9% of the girls desired to be underweight and 73.0% of the boys desired to be normal weight. Overweight or normal weight students were less satisfied with their body weights than underweight students. Girls had more weight control experience and concern compared to boys. Overweight girls spent longer times in watching TV compared to non-overweight girls (p < 0.001) and had more overeating behaviors (p < 0.05). Overweight students reported that they ate snacks less frequently than non-overweight students, which may be due to their tendency to report less eating. In conclusion, significant gender differences and weight status differences existed in weight perception, weight satisfaction, and weight control experience and concern. Because perception of overweight is likely to lead to unhealthy eating behaviors and weight control, efforts for adolescents to improve accuracy of weight perceptions and to understand the benefits of being healthier are needed.

Relationships among Personality Preferences, Psychosocial Factors and Dietary Habits of Middle School Students: Hye Sung Kim, Hye Young P Kim; Korean J Community Nutr 2007;12(5):511-518. Published online October 31, 2007

Abstract PDF: The purpose of this study was to obtain an understanding of the association of personality preferences and food behavior factors in middle school students. The subjects were 319 boys and girls in a middle school located in Kyunggi province. A self-administered questionnaire was used to assess demographic factors, dietary habits and psychosocial factors including self-efficacy, perceived benefits and barriers. The MMTIC (Murphy-Meisgeier Type Inventory for Children) test was used to assess the personality preferences of the students. Sixty-seven percent of the subjects were extrovert, 53.9% were the sensing type, 76.8% were the feeling type and 81.8% were the perceiving type in personality preferences. The extrovert had higher self-efficacy than the introvert. The feeling type perceived more benefits and fewer barriers than the thinking type. The education levels of the parents, especially mothers, were positively related with self-efficacy and dietary habit scores of the students. The self-efficacy and perceived benefits and barriers were significantly associated with dietary habits of the students (explained variance: 17.9%). Results of this study presented the relationship of character types and parents' education levels on psychosocial food behavior factors and a need for the development of tailored nutrition education program considering these factors.

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.

Nutrient Density of Fast-Food Consumed by the Middle School Students in Cheongju City: Kinam Kim, Enjoo Park; Korean J Community Nutr 2005;10(3):271-280. Published online June 30, 2005

Abstract PDF: The purpose of this study was to investigate fast-food consumption and it's nutrient density, and the correlation between subject's characteristics and consumption frequency of fast-foods among middle school students. The questionnaires were distributed to 150 male and 190 female students in Cheongju city. The data were analyzed using SAS and statistics used were percent of frequency, chi-test, t-test, and pearson's correlation coefficient. The main reasons for using fast-food restaurants were 'good taste' and 'convenience'. The major concerns when the subjects choose fast-foods were 'taste (65.9%), price (20.3%) and 'nutrition' (6.0%). The consumption pattern of fast-foods go as follows: twice a month (42.3%), once a week (31.5%), and less than once a week. The number of fast food items that the subjects ate for one meal was two (46.0%) or three (33.2%). The most frequently chosen combination of foods for number of two choices was beefburger and cola . The mean average energy intake from fast foods for one meal was 620.7 kcal for male, 504.5 kcal for female. The energy ratio of carbohydrate :protein :fat from fast foods was 49 :14 :43, which means fat intake is much higher than recommended level (20%). Fiber was appeared to be the lowest on the nutrient density which was 17.7% of the recommended level for Koreans, vitamin C was next (22.8% for male, 20.7% for female). In mineral, iron was the lowest (71.8% for male, 67.1% for female), and protein was over 100% for both males and females. Frequency of fast food intake was positively correlated with eating frequency of the salty, the sweets, ham, caffeine containing foods, instant noodles, and cookies. In conclusion, frequent consumption of fast foods can lead unbalanced nutrient intakes for middle school students, and those who consumed fast foods frequently showed undesirable food habits in their daily meal. Therefore, nutrition education for middle school students should be needed to encourage them to choose more nutritious food and have healthier dietary pattern.

A Study on the Status of Beverage Consumption of the Middle School Students in Jeonju: Moon Ja Song, Eun Mi An, Hee Sook Shon, Suk Bae Kim, Youn Soo Cha; Korean J Community Nutr 2005;10(2):174-182. Published online April 30, 2005

Abstract PDF: To investigate how the beverage consumption of middle school students are different in some respects; favorite kinds, drinking time and so on. 579 middle school students in Jeonju were participated in this study. This study shows the frequency of drinking beverage and the correlation between the frequency and the various factors to have effects on the frequency. The students usually drink water 8.55 times, milk or yogurt 3.01 times, sport beverage 2.13 times, soft drink 1.93 times, and fruit and vegetable juice 1.85 times for one week. The boy students prefer more soft or sport drink to the girl students. However the drinking of other beverages such as water, milk, juice, traditional ones don't have any meaningful differences between the boys and the girls. The students drink water mostly when they have meals. And the second consuming beverage is milk at table. It explains the students who drink more milk than water with bread. There is a big difference according to their excercise frequency. The students who excercise regularly or excercise over 3 hours drink more soft or sport drink and milk or yogurt than the students who exercise less than 1 hour. The beverages are firstly needed during the exercise because they sweat. And the second beverage time is when they have snacks and when they take a break. It should be suggested that nutrition education targeted to middle school students and their parents should encourage limited consumption of soft drinks. Therefore, policies that limit students' access to soft drinks at schools should be promoted.

Abstract PDF: Proper nutrient intakes and physical fitness focus one's attention on health promotion. This study was conducted to investigate nutrient intakes and physical fitness by BMI in middle school students. Health-related questionnaire, dietary intakes, food frequency questionnaire and physical fitness were studied. There were no significant differences in health-related questionnaire, food frequency questionnaire and physical fitness by BMI, but several nutrition intakes, preference of salty tastes and the proportion of iron deficiency of female students were significantly different by BMI. Although the female obese group (BMI 85 - 100 percentile) had decreased the proportion of iron deficiency and increased fish intake frequency than other groups, obese females did not show better physical fitmess than other groups. And the average Ca intake was below 75% of Korean RDA in both male and female students. Significantly positive correlation was found between calorie intake and push-up of normal (BMI 15 - 84 percentile) male students (r = 0.29), also significantly negative correlation was found between protein intake and 50m dash of normal female students (r = 0.22). And significantly positive correlation was found between beans and bent knee sit-up of normal male students (r = 0.25), and significantly positive correlations were found between beans, meat, eggs, green & yellow vegetable and sit and reach (r = 0.20, r = 0.28, r = 0.21, r = 0.19) and significantly negative correlation was found between beans and long distance race of normal female students. Therefore, this study suggests that proper nutrition and non-obese states should be achieved for health promotion in middle school students.

Abstract PDF: This research was to investigate the operation of contracted food service management and menu preferences of middle school students in Seoul. Questionnaires were distributed between Dec. 1 and 20, 2000 in 10 middle schools. Statistical data analyses were completed using the SAS package, including the mean, standard deviation and frequency analysis. The results can be summarized as follows: The average number of meals per middle school was 1,000 and only lunch was served in each school. In terms of facilities and equipment, low rates of the possession of cooking equipment and food carts were the major hindrance to work and production efficiency. The students' main demands were taste, sanitation, variety of food, the introduction of brand foods, the price of foods, and the speed of reaction to their dissatisfaction. Most of the schools provided rice for lunch, while the students preferred noodles, mandu and bread. beef-rib soup was preferred to broth. For side dishes, fish, roasted meat and fried foods were highly favored, along with processed foods, with low preferences for vegetables. The middle school students favored fruits.

Smoking Status and Dietary Habits of Middle School Students: Eun Hee Jung; Korean J Community Nutr 2002;7(1):14-22. Published online February 28, 2002

Abstract PDF: Adolescent smoking has been a great concern with respect to it's causing more serious health problems than adult smoking. The smoking status and habits of middle school students were studied using anonymous questionnaires, and their dietary habits were compared. Ninety-two of 4l4 students (22.2%) had experienced smoking, and 62.0% of them began in primary school, mostly out of curiosity. The most plausible reasons for smoking were 'boredom' and/or 'stress reduction'. Dietary habits were generally inadequate in the smoking group. Compared with the non-smoking group, the smoking group paid less attention to a balanced diet, more skipped breakfasts, more had irregular meal times and fewer snacked. There was no significant difference between the smoking and non-smoking groups in food intake frequency, except of sweet foods and caffeinated foods, which were more frequent consumed by the smoking group. These results suggest that more attention needs to be paid to nutrition and health education programs in elementary schools and also that proper support programs for smoking by themselves.

Abstract PDF: This study was conducted to evaluate the eating behavior and to analyze the various factors affecting eating behavior among middle school students. The subjents consisted of 212 middle school students(106 boys and 106 girls between 13-14 years) residing in Seoul. A questionnaire was used as the questionnaire consisted of four parts : the socio-demographic characteristics of the subjects, value toward food and nutrition, diet diversity(the number of food items) and eating behavior. Results showed that fifty three point five percent of males and fifty seven percent of females skipped breakfast. The main reason for skipping breakfast was shortage of time. Fifty five percent of the total number of subjects stated that they had more than two plasant meals a day. The number of food items eaten was significantly higher in males than in females. In only 16.4% of total subjects(18.5% of male and 14.2% of female), the primary pursuit in having meals was not to satisfy hunger but to consider nutrition and health. The eating behavior of the adolescents showed that 65% of the subjects had a 'good' eating behavior score and 17.4% had scores of 'excellent' and 'poor' respectively. The existence of parents, the economic level of the family, and concern of health and nutrition affected the eating behavior score. The less the subject skipped breakfast, the greater they placed a value toward food and nutrition. Value toward food and nutrition had a significant influence on their eating behavior. Those who placed a value toward food and nutrition had a higher eating behavior. Those who placed a value toward food and nutrition had a higher eating eating behavior. As a result of the multiple regression analysis, factors affecting eating behavior were 'pleasant meal' , 'the value toward food and nutrition' and 'the numbers of food items' in order(R2=0.2984).
