The purpose of this study was to investigate the association of interpersonal relationships with snack preference and the intake frequency of snacks with a primary focus on obesity index and snack preparations in upper grade (5~6th) elementary school students. A total of 719 students in Gyeongsangnam-do province were recruited and a questionnaire-based survey was conducted. Data were analyzed using the SPSS V18.0. The results were as follows : A total score of interpersonal relationships was 94.5 (full marks 125), and the scores of 7 factors consisting interpersonal relationships were over 3.50(full marks 5.00). Overweight group had the lowest score in interpersonal relationships (p<0.01) and purchase group by oneself had a low score than the other groups in snacks preparation (p<0.001). Most favorite snacks were ice cream. Additionally, the snack purchase group showed higher scores than the cook group by family in 8 types of snack and a total score of preference (p<0.05~p<0.001). Milk and dairy products had the highest score in frequency of snack intake. And purchase group by oneself or family was a higher than cook group by family (p<0.01). Interpersonal relationships showed a positive effect on preference and intake frequency of milk and dairy products but their explanation powers (R2) were very low. The findings of this study provide fundamental information impact factor in snack preference and frequency of snack intake.

The purpose of this study was to compare the validity of obesity indices among the body mass index (BMI), waist circumference (WC), and body fat percentage (BF%), and to determine which is the most useful index to predict the risk of chronic diseases of elderly people. This study was conducted as a cross-sectional study at welfare centers in Seoul. The total number of subjects was 261 (68 men and 193 women) with age ≥60 years. The distribution of obesity using 3 obesity indices in the subjects with hypertension, diabetes, or arthritis was BF%>WC>BMI in elderly men and WC>BF%>BMI in elderly women. In elderly women, odds ratios (ORs) for hypertension in BMI and WC quartiles were significantly increased in quartile 2 and 3 (p<0.05). The ORs for hypertension, hyperlipidemia, and arthritis in BF% quartiles were significantly increased in quartile 3 and 4 (p<0.05). The BF% was sensitive obesity index for predicting the occurrence of chronic disease in men, and the WC was sensitive index in women. Our results suggested maintaining BMI less than 23.5 kg/m2, WC less than 82 cm, and BF less than 35% in order to prevent chronic diseases in elderly women.

This study was performed to examine the relationship between the body mass index (BMI), the body fat, and the serum lipids of post-menopausal women in rural areas. The subjects were 510 women aged 50 and over. As a result of this study, we found a trend of decreasing BMI as age increased, but body fat increased. In addition, there was a significant decreasing of the lean body mass than an increasing of the body mass index according to increasing age. Therefore, this study confirmed that a main cause of rural women being classified as obese is a decrease in lean body mass, rather than an increase in of body fat. Of all subjects, 36.3% (18.5≤BMI 〈 23) of all subjects were classified as having normal BMI, whereas only 21.4% were classified as having normal body fat. Out of 190 subjects who were body fat 30% and over, 38 subjects were classified as obese (BMI≥25) and 113 subjects were classified as overweight (23≤BMI 〈 25). The percentile of those with a BMI of 25kg/m2 was 70, and they had 30.82% body fat. HDL cholesterol showed a negative correlation with anthropometric factors (height, weight, body mass index, waist circumference, waist hip ratio, body fat), and total cholesterol, LDL cholesterol, and triglycerides showed a positive correlation. Especially, total cholesterol, LDL cholesterol, and hip circumference showed significant correlations. Because of differences in the body fat and lean body mass by age group, it seems difficult to assess obesity via BMI only. The elderly especially should have a higher significance placed on body fat or abdominal fat than only BMI.

This study was conducted to investigate the change in the anthropometric values, biochemical index, nutritional knowledge, food habits and nutrient intakes in obese children after a weight control program. The subjects of the study were 22 obese children with an obesity index over 120%. The children that participated in this study took nutritional education for weight control along with exercise once a week. The weight control program was conducted for 10 weeks. The BMI, WHR (Waist-Hip ratio), body fat (%) significantly decreased at the end of the weight control program. Total cholesterol and LDL cholesterol were also significantly decreased. The nutritional knowledge scores and knowledge score about obesity were slightly improved. Energy intake significantly decreased from 1768 to 1421 kcal. Intake of Ca, Na, K, vitamin A, vitamin B6, vitamin C and folate increased, while intakes of P, Zn, vitamin B1, vitamin B2, vitamin E and niacin decreased. The distribution of energy intake was significantly changed for the better. The percent fat consumed decreased from 26.5 to 19.7%. In addition, the distribution of energy intake in the meals was changed, where the percent calories consumed during lunch significantly increased from 31.4 to 40.1% and the calorie percentage consumed from snacks significantly decreased from 17.6 to 10.7%. In conclusion, the nutritional education in the weight control program, which was conducted for 10 weeks, was effective in improving the anthropometric values, biochemical index and nutrient intake although nutrition knowledge and eating behaviors only changed slightly. Thus, nutritional weight control programs for obese children should be continuously provided under the proper cooperation of a nutritional teacher at elementary schools.

Recently, obesity that is increasingly becoming a major cause of various diseases and safety accidents in work places is emerging as a serious social problem. It is due to economic growth and improvement of living environments. Many researches are trying to find the root cause of obesity. Thus, the main objective of this study is to analyze obesity index of citizens in Seoul which is a metropolis of Korea and a densely populated district. The data used in this study included 179 men and 152 woman subjects who are living in Seoul. Somatotype using Rohrer Index can be classified by 3 types (thin, standard, obesity). In order to analyze a detailed somatotype of citizens, age groups are divided into 30~34, 35~39, 40~49, and 50~59 years according to gender, respectively. In order to compare and analyze data, Coefficient of Variance, Cronbach's Alpha, Rohrer Idex and Drop Value were used in this study. The results of this study can be applied to the comfortable and safe work environments for workers.

Nowadays obesity has been become a serious social issue. Many researches are trying to find the root cause of obesity. Obesity causes various kinds of disease and safety accidents in work places. Thus, the main objective of this study is to analyze obesity index of citizens in Seoul which is a metropolis of Korea and a densely populated district. In order to analyze a detailed somatotype of citizens, age groups are divided into 30-34 years, 35-39 years, 40-49 years, and 50-59 years according to gender respectively. The result of this study can be applied to the comfortable and appropriate design for workers.

Recently, due to economic growth, living environment has been convenient and comfortable and so human activities were decreased. Consequently energy consumption was also decreased. Also the habit of food intake has been changed and the tendency of obesity has been increased. The main objective of this paper is to provide analysis of obesity index of residents in six metropolitan cities. According to analysis of Rohrer Index, there were significant differences regionally between men and women in metropolitan cities. Through analysis of Drop Value, it was found that there were significant differences regionally between men and women in metropolitan cities on circumferences of chest, waist and buttocks. The result of this research can be utilized in manufacturing and design of uniforms and equipments for safety.

This study was carried out to compare UCP2 polymorphism, dietary habits, and obesity index in normal and obese university students. The survey was carried out using self-questionnaires collected from the 126 normal and 60 obese university students. The results are summarized as follows. Breakfast was skipped in 43.7% of normal and 49.3% of obesity students and it appeared obese students eat faster than normal students. The percentage of weight control experience were 49.2 and 71.0 in the normal and obese students, respectively. Blood levels of lipid profiles(triglyceride, LDL cholesterol, and HDL cholesterol), hemoglobin, AST and ALT were anaylzed. In UCP2 genes, the frequency of deletion homozygote(DD) was 71.5%, heterozygote(DI) was 26.9% and insertion homozygote(II) was 1.6%. Plasma levels of triglyceride, total cholesterol, LDL cholesterol, and HDL cholesterol of normal students were 79.06, 172.25, 100.86 and 57.03 mg/dl, and those of obese students were 93.06, 173.22, 101.22 and 54.39 mg/dl, respectively. Blood parameters were in normal range in both group. Plasma triglyceride, total cholesterol and LDL cholesterol levels of obese students were higher than those of normal students. On the other hand, plasma HDL cholesterol levels of obese students were lower than those of normal students. Plasma levels of AST and ALT were in normal range in both group. However, AST and ALT levels of obese students were higher than that of normal students. Thus, it was recommended for them to have a nutritional education program to improve their dietary and living habits for obese students’health. Nutritional education program should also be organized practically and systematically.

The main objective of this paper is to provide analysis of obesity index of residents in six metropolitan cities. According to analysis of Rohrer Index, there was significant difference regionally between men and women in metropolitan cities. Through analysis of Drop Value, it was found that there were significant differences regionally between men and women in metropolitan cities on circumferences of chest, waist and buttocks. The result of this research can be utilized in manufacturing and design of uniforms and equipments for safety.

The study aims to examine whether regular leisure activity of the elderly with active and passive types has a beneficial effect to enhance their health condition. The elderly subjects of 164 (82 of elderly who do active leisure and 82 of elderly who do passive leisure) aged over 60 years in Suwon area were employed. Survey questionnaires were administered to investigate general characteristics, life style, and health status along with anthropometric measurement. From the findings, the elderly who do active leisure were highly educated and better in living status. The elderly who do passive leisure showed higher drinking and smoking rates as well as higher obesity and overweight rates in comparison to the other counterpart. Furthermore, the elderly who do passive leisure were poor in health status. 'Painful knee and eye', 'lower back pain', and 'fatigue' were the most prevalent among subjective symptoms of the elderly. In conclusion, the elderly with active leisure activity seemed to have better life style and maintain good health status. Therefore, it is critically important to establish the health program combined with various leisure activity for the seniors to promote and energize the later years of life.

This study was conducted to examine the correlation among meals variety, obesity index, blood pressure, and lipid profiles of Korean adults. A total of 308 adults(men 124, women 184) measured the anthropometric characteristics, blood pressure, dietary intake using 24-hour recall method, and serum lipid profile. The average ages of the study subjects were 50.9 yrs in men and 51.4 yrs in women. The average height, weight and BMI were 166.3 cm, 68.4 kg, 24.7 kg/cm2 in men and 154.3 cm, 59.8 kg, 25.0 kg/cm2 in women, respectively. The numbers of food items in meal of men and women were 14.1, 15.9 for breakfast, 15.7, 15.9 for lunch, 14.7, 14.1 for dinner, respectively. The numbers of dish items in meal of men and women were 4.0, 4.3 for breakfast, 4.3, 4.3 for lunch, 4.2, 3.9 for dinner, respectively. The average blood pressure, total cholesterol, triglyceride, HDL-cholesterol, LDL-cholesterol and atherogenic index were 126.6/76.0 mmHg, 181.0 mg/dL, 157.7 mg/dL, 40.9 mg/dL, 108.6 mg/dL, 3.5 in men and 123.2/73.6 mmHg, 185.0 mg/dL, 137.3 mg/dL, 44.8 mg/dL, 112.7 mg/dL, 3.2 in women, respectively. The total cholesterol was negatively correlated to the number of food item for lunch(p〈0.05). Therefore, more systematic studies to investigate the meal variety roles of blood lipids in meals of adults were required.

The factors of obesity related with food habits were assessed to provide information for nutrition education database. The subjects in this study were 234 primary school children in Busan. Children were classified into normal and obese groups(mildly obese, moderately obese and severely obese) by obesity index. In self-recognition of body image, only 28.6% of MI group considered themselves as 'overweight or obese'. 87.2% of the subjects controlled their weight method with exercise. With regard to meal speed, 64.5% of the subjects ate fast(≤15 min.). The study also found that 79.8% of the subjects ate breakfast, 56.4% of the subjects them were moderate by obese, 40.8% of the subjects ate snacks after dinner. Eating speed, meal volume and snacks money per day were significantly different in obesity. Preference for eating out was Korean Chinese, Western and Japanese food, in order. Favorite food for snack, such as ddukbokki, fruits, milk. fried foods and candy and caramel were significantly different in obesity(p〈0.05). However hamberger, pizza and chocolate were not significantly different in obesity. The most preference snack for all the subjects were fruits and ice cream. In food preference, potato, dduk, meats, fishes, cheese, milk, ice cream were significantly different in obesity. The distasteful food for subjects were patbab, vegetables, shellfishes and salt-fermented foods. From above results, obesity of children was related to meal speed, meal volume and snacks motley per day. Therefore, these results suggest that continuous and practical nutrition education to change food habits art necessary to avoid child obesity.

The present study was conducted to investigate the relation of eating behavior and food intake to 534 adolescents' obesity indices. Group means of relative body weight (RBW) were 93.66 for males and 97.12 for females. Body mass index(BMI) were 20.39 for males and 20.41 for females. Respondents were divided into 3 groups on the basis of RBW as an obesity index. Astonishingly, 44.76% of total respondents were underweight and 12.92% overweight and obese. 64.54% of respondents usually skipped their breakfasts and 24.23% their dinners. More males did not have their breakfasts than females. In contrast, more females skipped their dinners than males. A significant difference was found between males and females in their eating habits(p<.001) that should be changed. As their undesirable eating habits, males pointed out 'skipping meals', while females stressed 'overeating'. There were more overeating respondents in the overweight group, while more respondents skipping their meals were found in the underweight group. Many females(72.79%) and males(52.78%) tended to alternate consistently overeating and fasting to lose weight. The most important reason for losing weight was to improve their appearance(61.12%). In addition, nutrient score indices of respondents were very low with a mean of 33.39. Only 42.13% of total respondents showed good nutrient score indices. More males ate meat, bean, white vegetables, potato and fat than females(p<.05), whereas more females ate bread, rice cake and fruit than males(p<.01). Among the 3 groups -overweight, normal weight and underweight groups, overweight group was the most eaters of meat, fish, egg and milk; underweight group was the least eaters of them.

This survey was conducted to investigate the relation of children's obesity index to their mothers' food habit during the October in 1995. The survey covered a total of 492 mothers whose children were in the fifth grade of elementary schools in Cheju City area. The results are summarized as follows: 1.The surveyed children's average WLI(Weight-Length Index) is 107.08. WLI shows that 16.1% of them are overweight, 16.1% obese and 49.8% ideally weighted. The mothers' average BMI(Body Mass Index) is 22.4. 21.8% of them are underweight and 69.4% normal. The children's obesity index is significantly correlated to their fathers', but not significant to their mothers'. 2.As to the food habit I (balance of nutrients intake), 58.4% of the mothers have 'excellent' or 'good' food habit and the mean score is 14.95 out of maximum possible score 24.0. Concerning to the food habit II (intake of sugar, fat and salt etc.), 87.4% of mothers have 'good' or 'fair' food habit and the mean score of is 13.34 out of maximum (possible score) 20.0. The mothers' food habit I and II, as a whole, have no significant effect on the children's obesity index, but in some items the significant relations are founded. The children's chesty index is significantly related to the intake of eggs (P<0.05) and pan-broiled or fried foods (P<0.05). The amount of mothers' food intake is significantly relevant to their obesity index (P<0.001), but not significantly to their children's. The food habit of mothers who have taken midnight snack almost every day are significantly related to their children's chesty index (P<0.05). The findings of the study emphasize the importance of the nutrition education to ensure health and better physical fitness for children and their mothers.

An ecological survey of food and nutrition was conducted in April and May, among 278 children, 6 to 12 years old, of the Youido elementary school, which offers no school lunch program, and is situated in Youido delta of Han River side of Seoul, known as the location of one of the socioeconomically high groups; Eighteen percent and 18.3% of subjects were proven to be overweight and obese, respectively. With regard to frequency of skipping breakfast, 28.4% of the subjects skipped breakfast often and 2.5% of subjects skipped breakfast every morning. Obese children showed good appetite and the time consumed for eating was shorter than those of normal or overweight children. Most serious anxiety among the mothers for those children was food habit of `eating rapidly' and `overeating'. Another striking observation was that 14.4% of the subjects ate only one side-dish with boiled rice, and such a pattern was more often found in the normal or slim group. Most of the subjects had their snacks after being back in home from school. Thirty-one percent of the children had snacks when they felt hungry, 69% had snacks for various reasons such as `habitually', `for unwinding', and `mother gives me snacks'. Thirty-eight percent of the boys and 19% of the girls had physical exercise everyday and overweight and obese children got exercise more frequently. But the time consumed for exercise was much more shorter than that of normal subjects. Most of the children liked fruits, meats, and biscuit, in contrast, lowest preferency was for vegetables, fermented fish products, and boiled rice mixed with other grains. Obese children experienced more kinds of food than normal or slim group. The study found that habits of overeating due to good appetite and eating rapidly were recognized as one of dominant reasons causing obesity among children. On the other hand, serious dietary problem of children of normal or slim group was eating less variety of food. Active nutrition education for both children and mothers will be recommended with joint participation of teachers.
