The purpose of this research was to study food behaviors and nutrient intakes according to body mass index(BMI) and body image recognition in 211 female university students in Incheon. The majority of the surveyed subjects were in the normal range for BMI. Most of these female university students preferred a thin body type and were not satisfied with their body shapes. Most also controlled their body weight for appearance by exercising and limiting food intake. The obese group often ate processed foods(p<0.01) and ate out(p<0.05). The underweight group and normal-weight group took vitamins and supplements more frequently(p<0.001). Those students who recognized their body image as a 'fat shape' had good appetites(p<0.05) and those who recognized themselves as 'normal shape' considered food formulations ate every meal (p<0.05) and consumed vitamins and other supplements frequently(p<0.01). The mean calorie intake of all students was about 80% of the recommend amount, so there was a risk of lack of various nutrients. The 'fat' students by body image recognition had lower calorie intakes in order to reduce body weight. In all the groups, there was a lack of vitamins $B_1$ and $B_2$, as well as the minerals Ca and Fe. Therefore, education on correct body image recognition and training on proper weight control are deemed necessary. In addition, education and counseling on nutrition that are tailored to individual status are needed.

Two hundred sixty six children were retrospectively surveyed from first to fifth grade to find out the status of obesity during four years. The obesity index was gained by height and weight data from student's health file and the data about eating behaviors and weight control behaviors, etc. were collected by questionnaires. Children assigned to one of the following groups : underweight, normal, overweight and obese. The results were as follows ; 1. Obese children were 18.6%(n=27) of boys and 10.8%(n=13) of girls at fifth grade. 2. Twenty eight children among forty obese children at fifth grade were also overweight or obese at first grade, and the other twelve was normal. 3. Breakfast skipping rate was significantly high among underweight and obese group of boys(p<0.01).The most children(87.6%) had prejudice for special foods. 4. The rate of agreement between obesity index and self recognition of body image was 60.7% in boys and 63.6% in girls. 5. Forty two point five percent of children have ever tried weight control as exercise(35.7%), reducing sugars and snacks(27%), fasting(23.8%), avoiding fatty foods(12.7%), taking diet food or drug(0.8%). In conclusion, the prevalence of children obesity is gradually increasing and children tried weight control without right guidances. In order to prevent progress into adulthood obesity, nutrition education should be followed with school foodservice including the right perception for obesity, proper weight control and eating behavior modification.

The objective of this study was to investigate the prevalence rate and correlates of weight control behaviors among adolescents in Korea. We analyzed data on 37,472 adolescents aged 12-18 years from the 2011 7th Korea Youth Risk Behavior web-based Survey. The results of this study was as following. First, the prevalence rate of healthy, unhealthy and extreme weight control behaviors was significantly higher in girls than in boys. Second, in both genders, healthy and unhealthy weight control behaviors were more common among obese adolescents than non-obese adolescents. But, use of diet pills were not prescription by doctor was more common in underweight boys and obese girls than others. Third, gender, school, family affluence scale, mother's education level, body shape perception(BSP), weight status predicted prevalence rate of healthy weight control behaviors. Gender, school, region, father's education level, BSP predicted prevalence rate of unhealthy weight control behaviors. Gender, school, BSP, weight status predicted prevalence rate of extreme weight control behaviors. These findings suggest the needs to design appropriate prevention program that can induce healthy weight control behaviors.

This study was conducted to investigate the effects of weight control programs on BMI, serum profiles, nutrition knowledge and eating behaviors of adult obese women. The subjects of this study were 33 adult obese women aged 30-65 years residing in Seoul. The weight control program for obese women included nutritional education, cognitive behavioral therapy and exercise for 12 weeks. The weight control experience of the subjects was 60.6%. They preferred physical exercise and diet restriction to weight control and 72.7% of subjects answered that the reasons for wanting to control their weight was health. The BMI of test subjects significantly decreased (p<0.001) from 28.3 to 27.1 after the 12 weeks of the weight control program. In addition, the % body fat significantly decreased (p<0.001) from 36.4% to 34.5% after completion of the weight control program. SGPT levels in the serum were also significantly decreased (p<0.05) after the program. Triglyceride levels significantly decreased from 194.9 mg/dL to 98.1 mg/dL (p<0.01) and the HDL cholesterol level significantly increased (p<0.01) from 55.8 mg/dL to 60.0 mg/dL after completion of the weight control program. Nutritional knowledge and eating behavior scores were significantly increased (p<0.001). In addition, the eating self-efficacy of the subjects was significantly increased (p<0.01); however, the food diversity scores were not changed after the program. These results suggest that the weight control program for adult obese women may be effectively used to promote weight reduction and improve nutritional knowledge and eating behavior.

The purpose of this research is to analyzed the Korean adolescents' weight control behaviors by BMI(Body Mass Index) and body shape perception. The data of this study abtained 73,238 adolescents, aged 12-18years from the '2010 6th Korea Youth Risk Behavior web-based Survey. The data were analyzed by frequency, percentile, chi-square test, Binominal Logistic Regression analysis. The results of this research were as following. First, the answer to question about adolescents' body shape perception is high in "normal" and "a little fat", but the result of BMI show that the most of them are in "underweight". Second, the female students tends to perceive themselves obese than male students do. Third, the female student try to lose weight but male student try to gain weight. Also the higher BMI is, the more the student have tendency to try to lose their weight. In conclusion, BSP leds directly weight control behavior, so in order to reduce unnecessary weight loss or improper methods weight control behavior. It is important to educate the students to have a sound perception about body shape.

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

The purpose of study was to test the hypothesis that three are differences in body size dietary behavior and nutrient intakes of adolescent girls with weight control experience. Cross-sectional survey was carried out with a questionnaire and anthropometric measurements . Subjects were 724 healthy adolescent girls from middle and high schools of urban and rural areas in Inchon and divided into two subgroups with weight control experience. Subjects trying to lose weigh were 25.1% in middle school girls and 47.1% in high school girls. There were significant differences in weight and BMI between weight control experience and non- experienced groups in middle school students. There were significant differences in skipping meals and reason of skipping meals between weigh control experience and non-experience groups which might show that skipping meal was used as a weight loss method among female school students. There was no significant difference in nutrient intakes between weight control experienced and non-experienced groups in middle and high school subjects. these results suggest that nutrition education is necessary for adolescent girls to practice appropriate weigh control strategies including desirable eating habits and adequate intake of nutrients such as energy vitamin A vitamin B$_2$calcium and iron.

This study was conducted to establish the effects of subjective body-forming perception on weight-controlling behavior and weight loss, and to suggest the need for proper information and education. Using the data from the National Health and Nutrition Examination Survey conducted in the 6th period (2013-2015), 6,238 women aged 19 and over who have a body mass index of $18.5-25kg/m^2$ were analyzed. As a result, the higher the level of education and income level, the higher they were perceived to be obese, the more they chose to lose exercise and diet in order to lose weight across the board. The weight loss effort rate was higher in the obese body type recognition group, but the body weight type was the highest in the one year body weight change group (p < .001). As a result, subjective perception of body shape affected not only weight control behavior but also weight change (p < .001). Accordingly, it is necessary to have a systematic education on healthy weight-controlling behaviors, proper body image, and healthy body type recognition.

148 male and 153 female college students attitude toward weight control, diet behaviors and food habits were investigated by self questionnaire. Among the students, underweight students were 11.0$\%$, normal weight students were 63.5$\%$ and obese students were 25.6$\%$ by RBW standard, and underweight students were 16.0$\%$, nromal weight students were 70.4$\%$ and obese students were 13.6% by BMI standard. However, more than 10% of male and 38$\%$ of female students thought they were obese even thought their body weight were normal. Female students tended to overeat when they were stressed or in a bad mood and generally all participants had poor scores on the dietary attitudes test, however, male students had significantly higher scores than female students. Female students tended to choose food more for its taste. Collegestudents are in early stage of adult life and their dietary attitudes, food behaviors and life style will continue to their later life. Therefore college students need more good nutrition knowledge, positive dietary attitudes, modified life styles to prevent and treat collegestudents obesity.

This Quantitative study was investigated to examine the relationship between self-esteem on body image and disordered eating patterns in some university students. This study used a cross-sectional study design. Total 347 students participated in this study (88 male and 259 female) among three universities. The assessment of eating disorder was conducted by Eating Attitudes Test (EAT-26), a score of >or=20 identified individuals likely have an eating disorder, including anorexia nervosa and bulimia nervosa. Ideal body weight and current body weight were completed with self-evaluation. A distorted body image was independently related to the eating problem in the Logistic regression analysis. There were stronger relationships between their EAT-26 scores and their expected weight changes and weight control behaviors. Compared with the men, women showed highly wishful to loss for current body weight. In the relationship between score of EAT-26 and BMI distance by sex, levels of eating disorder showed linearly elevated toward increased BMI distance (Ideal BMI-Current BMI) (F-value=18.794, p<0.0001) in women, but there were not significant in men (F-value=2.028, p>0.05). In estimate on state-trait anxiety inventory according to quartile of BMI distance by sex, levels of state-trait anxiety were not significant difference by degree of body dissatisfaction in all sex. In addition, higher distorted body image was significantly increased numbers of weight control method and experience of side effects in female, but there were not showed significant relation between two variables in male.
