The purpose of this study was to evaluate the obesity and weight control prevalence according to the gender and weight control attempt among middle school students in Seoul and Gyeonggi-do, Korea. The mean age of subjects were 14.4 years old. The mean height, weight and BMI value of boy students were 164.0 cm, 53.0 kg, and $19.7kg/m^2$, respectively, and the mean height, weight and BMI value of girl students were 159.4 cm, 49.8kg, and $19.6kg/m^2$, respectively. Both weight and BMI value of the weight loss attempt groups were significantly heavier and higher than those of the other groups (p < 0.01). In the perception on the body image, the girls perceived themselves to be more fat compared to boys, and the weight loss attempt group perceived their body image to be more fat compared to the other groups (p < 0.001). As for the interest degree of weight control, the interest degree of girls was higher than that of boys (p < 0.01). According to weight control attempt, in the order of the weight loss attempt group, the weight gain attempt group and the no weight control attempt group, the interest degree was significantly higher (p < 0.001). In the frequency and hours of exercise, there was significant difference by gender (p < 0.001). According to weight control attempt, the weight gain attempt group exercised more frequently than the other attempt groups (p < 0.01).

In this study, the interest of female high school students's(N=500) for weight control, as well as nutrient intake status, were analyzed. The mean age, height, and weight of the subjects were, 19.3 years, 162.2 cm and 55.4 kg respectively. Mean BMI was $21.1 kg/m^2$. According to BMI, the percentage of underweight, normal weight, overweight, and obese were 18.5 %, 60.3%, 11.3%, and 11.3% respectively. By the BMI criteria, 60.3% of the subjects were normal weight while the rate of self-recognition was 41.5%. The degree of satisfaction regarding self-body image was only 17.1% and 60.9% showed an interest in weight control. The reason for weight reduction were appearance(65.1 %) and health(24.2%). The body areas where subjects wanted to lose weight included the thighs(32.9%) and whole body(29.3%). They believed the most effective weight control strategy was exercise(81.1 %) and the strategies they used were diet(59.1 %) and exercise(40.4%). Energy intake was 1,733.4 kcal which was 86.7% of the estimated energy requirements(EER). Calcium, vitamin $B_2$, and vitamin C intakes were less than EAR by 34.4%, 40.4%, and 59.6% respectively. The intake of dietary fiber was 5.1 g only 21.1 % of the adequate intake(AI). In summary, high school females interested in weight control have significantly less calcium intake than their peers. The correlations between interest in weight control and weight and BMI were significant(p<0.001). The results of this study suggest that to achieve optimal growth, improved diets that include calcium, vitamin $B_2$, and vitamin C are recommended. High school females interested in weight control should especially be targeted for education on calcium intake.

This study aimed to investigate the association between interest in beauty care and dietary behaviors of 581 (analysis rate 96.0%) high school girls in Incheon using a survey done in May 2019. Based on the degree of interest in beauty care, subjects were classified as "Beauty care group (n=346)", and "Non-beauty care group (n=235)". The mean age of the subjects was 16.5 years old. The beauty care group had significantly lower BMI than the non-beauty care group (p<0.01). The beauty care group showed a significantly higher interest in weight control than the non-beauty care group (p<0.001). The most time-consuming preschool morning activity in the beauty care group was beauty care, while that of the non-beauty care group was eating breakfast (p<0.001). The beauty care group had significantly higher frequency of exercise than the non-beauty care group (p<0.05). The number of individuals who skipped breakfast was significantly higher in the beauty care group. In addition, the beauty care group had a significantly higher frequency of taking morning snack, convenience food (p<0.01), sweet snacks (p<0.05), and processed beverages (p<0.05) than the non-beauty care group. Our result findings provide important information on the priority groups for nutrition education based on beauty care interest.

This study examined the state of health and weight maintenance according to the body mass index (BMI) , and explored demographic variables, diet variables, the degree of stress etc. The results presented were based on data collected from 428 women who are mothers of the middle school children in Jeongeup city. Using SPSS WIN (Ver 9.0) , the frequency, percentage, mean, standard deviation, chi-square, ANOVA, and correlation analysis were provided. The mean of BMI for the subjects was 22.6, the ratio of obese women (BMI $\geq$ 25) was 22.9%. The frequency of the reported circulation or respiratory related diseases was greater in the obese group compared to the normal weight ($20 \leq BMI \leq 25$) or the lean (BMI < 20) groups. The obese group had less awareness of obesity. Those who regard themselves obese had lower rates of satisfaction with their body shape and higher rates of interest in weight control. Approximately 65% of the subjects attempted weight reduction more than once. Subjects who were obese had the most undesirable dietary behavior. In particular, this group had the higher rates of rushed meals, overeating, meals while watching TV or newspapers, and snacking, and eating out. In analyzing the correlation of variables influencing obesity, there were positive correlations between obesity and overeating, obesity and the degree of stress. Correlations between obesity and satisfaction for life found to be negative. Moreover, stress had a positive correlation with obesity and overeating, and showed negative correlation with eating behavior. Consequently, stress seemed to induce undesirable eating behaviors and increase obesity. Of the demographic background variables, subjects who were obese tended to be older, had lower levels of education, higher rates of employment, longer period of marriage, the higher number of children, preschool children or children preparing for highschool or college, lower satisfaction with children and household life.
