Objectives : The purpose of this study was to determine what is useful index of abdominal visceral fat area among Korean obese adolescents. Methods : 35 obese adolescents who had visited Kirin Oriental Hospital from August 2004 to May 2006 were included in the study. Weight, height, waist and hip circumferences were measured. Abdominal visceral fat areas at L4-5 level were measured by computed tomography. The subjects were divided into two groups, according to sex. In each group, we investigated the correlation among waist circumference, waist/hip ratio, waist/height ratio, obesity degree and abdominal visceral fat area and evaluated that which one of these kinds of indices is the most useful predictor for visceral fat area in Korean obese adolescents. Results : There were significant correlation between waist circumference, waist/hip ratio, waist/height ratio and obesity index in both group. In boys waist/hip ratio had correlation with abdominal visceral fat area and in girls obesity index had significant correlation with abdominal visceral fat area. Conclusions : Our study suggests that waist/hip ratio in boys, obesity degree in girls can be a relatively good parameter for predicting abdominal visceral fat area.

To study the correlation with increasing body fat mass for the Standard Guideline for Korean Dietary Life, a nationwide, cross-sectional survey was performed with 178 male college students in december 2005. Among the student subjects, 76 were analyzed for body protein mass, body mineral mass, body fat mass, percent body fat, waist-hip ratio(WHR), body mass index(BMI) and obesity degree using Inbody 3.0(Biospace Co, Seoul, Korea). Body protein mass was at a high level of 92.1%, body mineral mass was at a low level of 94.7%. Body fat mass was at a high level of 28.9%, percent body fat was at a high level of 37.3%, WHR was at a high level of 31.6%, and obesity degree was at a high level of 38.2%, BMI was at a high level of 24.3% and BMR was observed at a high level of 41.8%. WHR was correlated with '7. Prepare food proper amount sanitarily.' and obesity degree, while BMl was were correlated with '4. Increase movement and eat proper amount.' positively. BMR was correlated with '6. Enjoy 3 meal a day regularly.' ArmCircle was correlated with '4. Increase movement and eat proper amount.' and fitness score was corrected with '4. Increase movement and eat proper amount', and '8. Enjoy Korean rice food style.' positively. Body protein mass and body mineral mass were negatively correlated with fruit, ArmCircle was positively correlated with fish, obesity degree was positively correlated with soup and BMI and ArmCircle were positively correlated with sweet. '8. Enjoy Korean rice food style.' was negatively significantly correlated with overweight, over percentage body fat, obesity degree > 120 and BMI. Male students were not practicing the Standard Guideline for Korean Dietary Life well with an average score of 37.7%. However, male students who are within the normal range of body composition analysis value have to notice that over range of weight, protein, percentage body fat, WHI and obesity degree was observed above average score of 30%.

Purpose: The purpose of this study was to evaluate the effects of an integrative weight control program including East Asian traditional medicine on the degree of obesity and body compositions. Method: Using one group pre-post test design, 63 subjects aged 19 years or older were conveniently recruited from D University hospital. The weight control program consisted of acupuncture, aerobic exercise, moderate caloric restriction, and behavioral modification for weight loss. Paired t-tests were conducted using the SPSS V18.0. Results: Body weight (t=10.44, p<.001), body fat mass (t=11.47, p<.001), percentage of body fat (t=11.49, p<.001), the degree of obesity (t=10.48, p<.001), body mass index (t=10.66, p<.001), waist circumference (t=10.25, p<.001), hip circumference (t=6.10, p<.001), and WHR (t=2.21, p=.040) decreased after administering the integrative weight control program. Conclusion: This integrative weight control program effectively reduced the obesity degree and percentage of body fat. Further study is needed to replicate our program in a larger sample with control group to validate the findings.

The purpose of this study was to compare nutrient intakes, blood lipids and bone mineral density of male (n = 59) and female (n = 172) teachers according to the obesity index by percentage of body fat and age. The energy intakes of obesity group were higher than normal group in male (p < 0.05), but were not significant in female. The protein intake ratio among three energy nutrients for male was higher than female (p < 0.001), and lipid intake ratio of obesity group in female was a little higher than male that was not significant. TC, LDL, TC/HDL, risk of coronary heart disease, blood glucose and blood pressure of obesity group were higher than normal group in female (p < 0.01 ~ p < 0.001), but were little significance in male. Risk of coronary heart disease was affected by gender (p < 0.001), obesity degree (p < 0.01), age (p < 0.001), and interaction of gender and age (p < 0.001). Blood glucose was affected by obesity degree (p < 0.05), but was not affected by age. T-scores of forearm for female (= -1.42) were lower than that of male = -0.95), and T-scores of obesity group in male (= 0.12) were higher than that of normal group (= -0.33) but were not significant in female. The T-scores of forearm for female were affected by age (p < 0.05) and gender (p < 0.01), but calcaneus was not affected by gender. These results suggest lipid intake ratio should be balanced for obesity group in female. Nutritional education for treatment obesity to prevent hyperlipidemia and arteriosclerosis is necessary for obesity group and older age groups. T-scores of forearm were lower than calcaneus, so arm exercise would be especially required to prevent osteoporosis for older age women groups.

Early evaluation of obesity is important. Obesity is defined as an excessive accumulation of fat that causes harm to health. Among patients who visit a hospital for weight-related issues, diseases other than body fat gain may be present; however, people often cannot distinguish between these issues and concerns. Therefore, among patients who visit the hospital with weight gain concerns, it is necessary to determine whether the weight gain is actually the result of excessive fat accumulation. After being diagnosed with obesity, the cause and degree of obesity, the amount and distribution of body fat, and the degree of risk should be evaluated. Additionally, obesity-related complications should be identified and, even if there are no complications, all related risk factors should be evaluated and managed. In all these processes, diagnostic methods such as history taking, physical examination, body fat measurement, blood tests, and imaging tests are necessary, but history taking and physical examination, which can provide a lot of information from the beginning, should not be overlooked.

Objectives The objectives of this study were to evaluate the correlations between the indices of obesity and percentage body fat by bioelectrical impedance analysis(BIA). Also, this study was designed to define the cut off values of percentage body fat by BIA which would represent BMI and degree of obesity in order to detect overweight and obesity in preschool children. Methods The height and weight of 683 children aged four to six years old were measured. Also, percentages of body fat were measured by BIA. Results There were high correlations between the boy's body fat percentages and degree of obesity(r=790). Also, there were high correlations between the girl's body fatpercentages and BMI(r=778). The cut off values of body fat percentage, which would correspond to those of BMI percentiles, were calculated by ROC curve analysis. To classify as an overweight, the correspondent cut off values of body fat percentage were 19.55% in boys and 22.35% in girls. For obesity, the cut off values were 28.80% in boys and 27.60% in girls. The cut off values of body fat percentage, which would correspond to degree of obesity were calculated by ROC curve analysis. To classify as an overweight, the correspondent cut off values of body fat percentage were 19.75% in boys and 22.35% in girls. For obesity, the cut off values were 29.05% in boys and 28.75% in girls. Conclusions According to the BMI criteria by the Korean pediatrics society in 2007, the most appropriate cut off values of body fat percentage in for four to six years old children were follows; for boys, 19.55% considered as overweight, and 28.80% as obese while for girls, 22.35% considered as overweight and 27.60% as obese. According to suggested degree of obesity criteria, the most appropriate cut off values of body fat percentage in for four to six old children were were follows; For boys, 19.75% was considered as overweight, and 29.05% as obesity. For girls, 22.35% was considered as overweight, and 28.75% as obese.

The purpose of this study was to investigate the variables which had effects on deit behavior of male and female high school students. The proposed variables are their body-related variables(body satisfaction, weight control experience, the degree of diet interest, and obesity) and self-esteem. The sample group used for the study consisted of 359 high school students(male=168, female=191). Measurement scales used for the study were those of body-related variables, self esteem and eating disorder behavior, and data analysis was performed using $X^2$, t-test, Pearson's correlation, regression analysis. The results are as follows. First, there is a significant difference between male and female high school students regarding their obesity perceived by themselves, body satisfaction, the degree of diet interest, weight control experience, and deit behavior. Second, In male students, diet behavior shows a positive correlation with the degree of diet interest, weight control experience, and body satisfaction, but shows a negative correlation with body satisfaction. In female students, diet behavior is positively correlated with the degree of diet interest, weight control experience, and obesity, but negatively correlated with body satisfaction and self-esteem. Third, in male students, the variables that showed a influence on diet behavior as an eating disorder are weight control experience, body satisfaction and obesity, in that the explanatory power of the variables is 51.7% with the highest mark on obesity. In female, the variables that showed a influence on diet behavior as an eating disorder are the degree of diet interest, weight control experience, body satisfaction and obesity, in that the explanatory power of the variables is 66.0%.

The purpose of this study was to investigate dietary behavior and nutritional knowledge related to sodium intake in high school students. A questionnaire survey was conducted in 400 high school students (200 boys) in Incheon, Korea. Survey data were analyzed according to gender and degree of obesity. The distribution of the degree of obesity was the highest in 231 normal weight individuals (57.8%), followed by 89 underweight (22.3%), 41 overweight (10.3%), and 39 obese (9.8%). The sodium-related undesirable dietary behavior score was 2.9 points out of 5 points. The detailed dietary behavior scores of 'I eat kimchi when I eat instant noodles or noodles' and 'I like dried fish with salt' were significantly higher in boys than in girls (p<0.05). It was found that boys consumed more frequently high sodium foods, such as pizza, hamburger, and hotdog than girls. According to the degree of obesity, the underweight group consumed more kimchi fried rice and potato chips frequently than the other groups (p<0.05). Preference for salty taste was not significantly different among the groups by gender and degree of obesity. Sodium-related nutritional knowledge score was 5.3 points out of 10 and which was significantly higher in girls or normal weight group than in boys or obesity group. These results suggest that nutritional education on sodium intake is needed because the nutritional knowledge of adolescents is relatively low. Moreover, intensive nutritional guidance is required, especially in boys or adolescents with undesirable degree of obesity.

This study was intended to provide basic data of nutrition education to a prevention of obesity and living patterns of elementary school students. Through the measurment of the actual obesity rate of children for students who were in the fifth and sixth grades of elementary school as well as their mothers, and by analyzing obesity-related factors. Children have started to have the characteristics obesity and obesity problems. 1. There were total 234 children including 133 boys (56.8％) and 101 girls (43.2％) for the study. There were 80 children in the fifth grade (34.2％) and 154 children in the sixth grade (65.8％). 2. Among the subjects 20.1％ were obese. By gender, the obesity rate of boys (27.1％) was higher than that of girls (l0.9％)(p＜0.01). By grade, children in the fifth grade (26.3％) had higher obesity rate than children in the sixth grade (l6.9％)(p＜0.05). 3. In terms of the educational level of parents, the obesity rate of children of parents who received university and／or higher education was 27.5％ (p＜0.05). 44.1％ of parents answered ‘I almost never give snack’s’(p＜0.01). 4. There was 32.8％ for an irregular quantity of meal. There was no obese child who under-ate (p＜0.05). In terms of impulse eating, ‘I eat.’ and ‘I don't eat.’ were 24.4％ and 25.9％ respectively. The obesity rate of the case of ‘I eat only food I like.’ was 10.6％ (p＜0.05). In terms of the obesity rate based on the daily average meal frequency, there was the highest rate of 26.1％ for I average meal frequency per day, 13.0％ for 2 daily average meal frequency, and 7.4％ for over 3 average meal frequency per day (p＜0.05). For a degree of a physical activity, the group of active physical activity (p＜0.05) and the group which liked the physical exercise showed a lower obesity rate (p＜0.001). The obesity rate of children who had regular exercise was 11.8％. It was lower than the obesity rate (24.8％) of children who didn't exercise (p＜0.01). The higher exercise frequency per week was, the lower the obesity rate was(p＜0.01). In terms of the exercise time, there was 8.3％ for over 60 minutes and 28.9％ for less 15 minutes. The group which had the long exercise time showed a lower obesity rate(p＜0.05). As the result, the education for obesity must enable students to recognize the warning signs for obesity and control their own weight with proper living patterns, by modifying behaviors considering the degree of obesity. Obesity must be controlled by the prevention and education connected with the family for all students as one of the school health programs. There must be also the development of a program through individual consultation considering the degree of obesity.
