This study is to investigate the concerns about obesity and diet behaviors among 565 middle and high school students in Ulsan. The results indicated that high school students rather than middle school students and girls rather than boys had higher concerns about obesity and diet behaviors. For the socio-economic variables, being female, a high school student, and a group with the least monthly allowance was higher concern about obesity and diet; and household income, educational level and occupation of the fathers also had significant impacts on the student concerns about obesity and diet behaviors. The variables of height, weight, PIBW (Percentage of Ideal Body Weight), and BMI (Body Mass Index) had significant impacts on the concerns about obesity and diet behaviors. Especially, students with normal weight had the highest concerns about obesity and diet, while obese students had the lowest concerns. (J Community Nutrition 7(4): $184\∼192$, 2005)

Obesity is an increasing public health and medical issue worldwide. It has been associated with several comorbidities, including diabetes, cardiovascular disease, stroke, and cancer. Chronic kidney disease (CKD) is another important comorbidity of obesity. Other major causes of CKD include hypertension and diabetes. However, the association between obesity and CKD is often overlooked. Among patients with CKD, patients with obesity were more vulnerable to have rapid kidney function decline than that of those with normal weight. Additionally, CKD is more prevalent among patients with obesity. These aggravations are induced through multiple mechanisms, specifically metabolic impairment of obesity and mechanical burden because of increasing intraabdominal renal pressure. Furthermore, the inflammation and lipotoxicity, caused by obesity, are critical in the CKD aggravation in patients with obesity. To prevent this, all adult patients with obesity are tested for CKD. The workup includes the estimated glomerular filtration rate and regular follow-up. Step-wise management is required for patients with obesity with CKD. Prompt reduction and management of obesity effectively delay CKD progression among patients with obesity and CKD. Therefore, weight loss is a core management for patients with obesity and CKD. Based on several studies, this article focused on the association between CKD and obesity, as well as the diagnosis and weight management of patients with obesity and CKD.

Since obesity has been a crucial issue regarding children's health in Korea, numerous studies have been conducted. However, it is difficult to locate studies that can help researchers and/or medical professionals who want to study behavioral differences between obese and normal weight (non-obese) children. The collected literature about obese childrens behaviors were accumulated by performing 'key word' searches from several web engines: 'obesity' 'children obesity' 'behavior' 'habit' 'eating behavior or habit' 'exercise' 'physical activity' and 'daily behavior'. The information was extracted and the behaviors were reviewed utilizing 30 papers that revealed any differences from normal weight children with at least p .05 level of significance. According to those studies, the obese children tended to skip meals more often as a method of losing weight. They also have an increased appetite, eat larger portions and rarely leave food on their plates. The obese children prefer to eat high fat, high calorie foods and eat faster than their normal weight counterparts. Also, the children usually eat alone and eat at irregular meal times. Beside the behaviors related to the standard three meals a day, obese children have high preferences for snacking. The children reported that with pocket money they usually eat certain types of snacks without parent approval. The children stated that they exercise more on a regular basis. However, when asked about their participation they were not likely to engage actively. Meanwhile, they tend to spend free time doing sedentary activities such as watching TV or playing on the computer. Since these studies used self -reported questionnaires with a small sample, size there may be difficulty in forming a basis about obese children's behaviors. Nevertheless, these findings are in accordance with other studies conducted in local as well as western countries. In conclusion, obese children have different daily behaviors or routines from normal weight children. It is recommended that altering these behavioral patterns to match those of normal weight children should be encouraged.

Purpose: The purpose of the study was to investigate the relationships between objective obesity, subjective obesity, body attitudes and dieting among college women. Method: The convenience sample consisted of 531 women. BMI was calculated based on self-reported weight and height. Body Attitudes Questionnaire (BAQ) was used to evaluate attitude toward women's body. Result: BMI mean score was 19.75. Based on BMI, 84.2 percent of the subjects were in a normal weight range and 0.9 percent of the subjects were obese. However, 26.9 percent of the subjects evaluated themselves as obese. Forty-one percent of the subjects were on a diet to reduce thier body weight. Body attitudes were associated with BMI and subjective obesity. BMI of the dieters was higher than that of the subjects who were not on a diet. Subjective obesity was associated with dieting. BAQ subscales except 'attractiveness' were associated with dieting. Conclusion: Many subjects were on a diet since they wanted to be thinner. Body attitudes were associated with dieting. Therefore, proper education is needed in weight management for young adult women.

This study was an investigation of obesity, food habits and daily nutrient intakes of the 4th grade elementary school students in daejeon. A total of 148 children(male:71, female:77) participated in the study. We classified the subjects into normal group and obese group according to the grade of obesity indices by body fat ratio(BFR), 70% of the male and 31% of the female were obese group. The average height, weight were $140.1{\pm}4.9cm$, $33.0{\pm}3.6kg$(obese group), $141.9{\pm}5.7cm$, $42.0{\pm}3.6kg$(normal group) for the male, $141.2{\pm}6.4cm$, $42.4{\pm}6.2kg$(obese group), $139.5{\pm}6.4cm$, $33.0{\pm}4.5kg$(normal group) for the female. Weight showed a noticeable increase in the obese group, but height was not statistically significant. In dietary habits, it wasn't statistically significant but male obese group showed statistically increase in terms of eating fast(p>0.05) and eating snacks before sleeping(p>0.01) and female obese group was higher in frequency of eating out a month than normal group. Energy intakes of obese group was more than normal group and the average intakes of Vit. A, folic acid, Ca, were below the RI. The average intakes of vit A, vit C, folic acid, Ca, were also below the RI in normal group. The average intakes of vit A, folic acid, Ca, Fe were below the RI in female. Especially in female the intake of Ca was only 53.6%(obese group), 56.4%(normal group) of RI. From these results, we knew prevalence of obesity in elementary school students were high and obese groups were high in energy intakes but low in essential nutrients. Therefore we have to try to prevent and treat childhood obesity. So nutrition education of balanced diet and good dietary habits is needed for elementary school students.

The aim of this study was to provide fundamental data by degree of obesity which was necessary to nutritional education for the formation of right eating and dietary guideline by researching food habits of children. In order to achieve this purpose, a survey was conducted on 3, 4, 5, 6th grade of students from 4 schools in S and G city in Jeolla-Namdo. The results was as follows. There were 384(44.4%) students were normal weight, 193(22.3) were overweight, and 287(33.2) were low weight by obesity indices. Comparing the student's subjective health condition among the degree of obesity, 40.4% of overweight recognized they were healthy, 30.1% recognized ordinary, and 57.1% of lean recognized they were healthy, 34.5% recognized ordinary. It was turned out that most students who were overweight and lean recognized healthy and normal. Family was reported to be the most impact factor on student's diet habits, and then Multimedia such as TV seemed to have a effect on overweight and lean students, but nutrition teachers had a direct influence on normal weight students. The most thing which eating habits for a reform was unbalanced diet. The students in this research have breakfast everyday and regularly. Regarding dietary attitudes, overweight group enjoyed eating healthy food more than normal and low body weight group did, and tried to eat what they have never eaten before. In conclusion, it's necessary for elementary school students that increase the control ability of self perceived health condition with education for good eating habit and grasp their condition themselves through the nutrition education in school.

The purpose of this study was to identify the adolescent girl's weight control practices, degree of obesity and body image. The data were collected from July 1st to 15th, 1996 using the questionnaire and the physical examination record. The subjects of this study were 295 junior high school girls. Darta were analyzed with percentages, means, t-test, ANOVA, Kruscal-Wallis one way ANOVA, Scheffe test and pearson correlation coefficients using the SPSS program. The results were as follows: 1. The mean for the degree of obesity in subjects was -1.26%. The 34.2% of the subjects were underweight, the 46.8% were normal, the 9.2% were overweight and the 9.8% were obese. The girls who perceived themselves obese were 39% and only the 47% of them were really over-weight and obese. 2. The mean score of body image was 139.30. It was 145.51 for underweight girls, 128.07 for normal weight girls and 125.17 for obese girls. The higher the degree of obesity was, the lower body image score was. The body image score of the girls who perceived themselves obese was significantly lower than that of the girls who perceived themselves normal or underweight. 3. The 65.1% of subjects experienced weight control practices. They reported that they had used the following weight control methods such as diet(42.2%), exercise(35.9%), diet and exercise(15.1%) and others including drug(6.8%). The degree of obesity was significantly higher and the body image score was significantly lower in the case of the girls who had weight control experiences than in the case of those who had no weight control experiences. 4. The 60% Of the subjects often had 2 meals per day. The 48.8% of the subjects tended to skip breakfast, the 7.8% would skip lunch and the 20% did not have dinner. The higher the degree of obesity was and the lower body image score was, the more the girls would skip their meals. In conclusion, many adolescent girls tended to believe their body weight heavier than their real body weight. Many girls who were not overweight and obese tried to lose weight. In the case of the girls whose degree of obesity was high or who perceived themselves obese, the body image score tended to get lower and the weight control practices tended to be increased.

Purpose : This study examines the differences in self-efficacy and health promoting behavior between obese students and normal weight students by gender; it tries to obtain basic data for the health guidance of obese students. Methods : Data were collected from 360 students (90 normal weight males, 90 obese males, 90 normal weight females, 90 obese females) using questionnaires about general characteristics, self-efficacy, and health promoting behavior. There were analyzed with descriptive statistics (frequency, percentage, mean, standard deviation), and a x$^2$ test, ANCOVA, and a Pearson's correlation of coefficient at the 0.05 significance level by using the SAS (version 8.01) Win Program. Results : The score of self-efficacy appears that in the case of boys, obese students are significantly lower than their normal weight counterparts (F=25.85, p=<.0001), while in the case of girls there is no significant difference between the two groups (F=.01, p=.9118). The score of health promoting behavior appears that in the case of boys, obese students are significantly lower than their normal weight counterparts (F=28.61, p=<.0001), while in the case of girls there is no significant difference between the two groups (F=1.25, p=.2643). The relation of self-efficacy and health promoting behavior shows a statistically significant correlation in all cases: obese boys (r=.69, p=<.0001), normal weight boys (r=.51, p=<.0001), obese girls (r=.67, p=<.0001), and normal weight girls (r=.49, p=<.0001). Conclusions : An evaluation study needs to see whether a program to encourage the self-efficacy of obese boys can be effective in health promoting behavior or weight control in the long run. As in this study more than half of the obese girls have mild-level obesity, a follow-up study should be conducted to examine the self-efficacy and health promoting behavior between middle or highly obese students and normal weight students.

The purpose of this study was to investigate the relationship among nutritional status, serum lipids and leptin of 134 elementary school students with different obesity index residing in Kyunggi-do, Korea. Subjects were assigned to under weight, normal weight or over weight group according to the their obesity index. Their nutritional status, serum lipid and leptin levels were evaluated based on 24-hr dietary recalls, anthropometric measurements and blood analysis. The mean weight, height and obesity index of total subjects was 150.8cm, 45.6kg and 5.4%. The mean % of body fat was higher while LBM and TBW (total body water) were lower in over weight subjects than those of other two groups. Total food, plant protein, carbohydrate, and vitamin C intakes of underweight male students were lower than those of overweight male students. The consumption of total fat was the highest in the female normal weight subjects and the lowest in female overweight subjects. Male students consumed more plant protein and vitamin C than female students. The mean daily intake of vitamin B$_2$, calcium and zinc of all subjects did not meet the Korean RDA. Also, iron intake of female students was lower than the Korean RDA. The mean level of serum leptin was the highest in male and female overweight subjects (p＜0.001). The HDL-cholesterol level was the highest in the underweight group of male subjects (p＜0.05) and in the normal weight group of female subjects (p＜0.001) The serum level of leptin and atherogenic index (AI) of females were higher than those of males. Serum leptin of total subjects had significantly positive correlation with obesity index, weight, SBP, body fat, cholesterol intake, serum triglyceride, and AI. However, serum leptin was negatively correlated with LBM, TBW, intake of plant protein, vitamin B$_1$, vitamin C and serum HDL-cholesterol. Obesity index was also positively correlated with weight, SBP, body fat, serum triglyceride and AI. To summarize the results, the vitamin B$_2$, calcium, zinc, iron and fiber intakes should be supplied to elementary school students, especially those who were overweight. The average serum leptin level of students showed remarkably positive correlation with obesity index, body fat, serum lipids and AI. Also, it was suggested that the serum leptin might be related to the dietary factors like cholesterol, plant protein, vitamin B$_1$ and vitamin C of elementary school students.

The purpose of this study was to compare weight control behaviour, eating habits and health-related life habits according to the obesity degree by body fat percentage (%Fat) among middle-aged women. The subjects were 170 middle-aged women who lived Gunsan City, and they were assigned to one of the following groups based on their %Fat; normal weight group (18% - < 28%), overweight group (28% - < 33%) and obesity group (over 33%). The height, body weight, %Fat, the circumference of waist and hip of them were measured. Eating habits and health-related life habits were evaluated based on questionnaires. The results were as follows. Their weight, %Fat, body mass index (BMI), relative body weight (RBW), waist, hip, and waist-hip ratio (WHR) were significantly higher in the obesity subjects when compared to the normal and overweight subjects. Self-perception for weight (p < 0.001), desire for weight control (p < 0.01), and reasons of weight control (p < 0.05) were different among three groups. The main skipped meal was breakfast (67.9%), reasons of skipping meals were different among three groups (p < 0.05), and main reasons were "lose one's appetite" and "have not enough time". Food habits score for each food was not significantly different among three groups, but eating the meal on thinking with food combination in normal group was higher than overweight and obesity group (p < 0.01). Correlation coefficients of food habits score and anthropometric measurements were that salty of food was negative and food habits scores were positive correlation for anthropometric measurements and obesity index (p < 0.05 - p < 0.001). Frequency of exercise and fitting exercise for body were different among three groups (p < 0.05). Obesity group was lower frequency of exercise than the other groups. Regular diet was positive correlation with food combination (p < 0.01), taking fish (p < 0.05), taking vegetables (p < 0.01), taking bean products (p < 0.01) and food habits score (p < 0.01), frequency of eating out and snacks were negative correlation with taking fruits and fishes. Therefore, proper nutritional education for middle-aged women in obesity group is recommended regular diet, good food habits and exercise. The middle-aged women must decrease the frequency of eating out, snack and the salty foods, and increase the fruits and vegetables. They must have healthy life styles for exercise, smoking, and drinking.
