Purpose
The aim of this study was to assess the body weight perception of adolescents and to investigate the difference between mental health and weight control behavior according to body weight perception.
Methods
Study data on 12-18 years old adolescents with normal BMI was obtained from the 6th Korea National Health and Nutrition Examination Survey (2013-2015). Rao-Scott Chi-square test and ANOVA were used for the analysis.
Results
The percentage of adolescents with a misperception of body weight was 43.3%, and their subjective health status (p=.013), stress perception (p=.001), and depression (p=.001) were worse than for adolescents who had the correct perception of their body weight. The percentage of adolescents who were trying to lose weight while perceiving their body weight as normal was 36.9%. Body weight control behavior had significant differences according to dietary intake (frequency of eating dinner (p=.015)), energy intake (p=.004), and carbohydrate intake (p<.001), but there was no significant difference according to exercise.
Conclusion
Parents, school teachers, and nurses should make efforts to ensure that Korean adolescents perceive their body weight correctly, and prevent unhealthy weight control behaviors.

PURPOSE
The purpose of this study was to identify the Health Promotion Life Profile of normal-weight and obese children, and factors related to obesity in elementary school children, and provide basic data for the development an obesity management program for these children.
METHOD
The survey participants were 878 fourth to sixth grade elementary school children in Gwangju. chi-square-test, t-test, ANOVA and multiple logistic regression with the SPSS program were used to analyze the collected data.
RESULTS
The Health Promotion Life Profile showed significant differences between normal-weight and obese groups according to food habits (t=3.305, p= .001) and exercise habits (t=-4.065, p=< .001). The Health Promotion Life Profile of obese children was also significantly different according to interest in weight control (F=3.044, p= .050), regular breakfast (F=3.699, p= .014), regular meals (F=6.868, p= .002). The multiple logistic regression analysis, showed that factors in obesity were significantly different according to gender, interest in weight control, fast eating, overeating and predilection for some food.
CONCLUSION
The results of this study suggest that items on Health Promotion Life Profile such as food habits and exercise habits should be included in education programs to prevent obesity in elementary school children.

PURPOSE
This study was done to evaluate the effects of Yoga exercise on improvements in physical flexibility, posture management behavior, and self-efficacy in adolescents.
METHOD
In this study, the design was a quasi-experimental research design with a one group pretest-posttest design. Participants were 32 students from one high school in Busan Metropolitan City, Korea, who did not engage in regular aerobic exercise and were willing to participate in this study. Yoga exercise was conducted for 70 minutes twice a week for 15 weeks. The data were collected from March 16 to June 22, 2004. The data were analyzed using descriptive statistics, and paired t-test with SPSS Win 12.0.
RESULTS
Trunk flexibility, posture management behavior, and self-efficacy significantly increased after the yoga exercise.
CONCLUSION
Yoga exercise is recommended as a useful nursing intervention that could help prevent spinal-curvature-related disorders among adolescents.

PURPOSE
This study was performed to test an obesity management program for elementary school children. The program was assessed by examining its effects on the obesity, dietary attitudes, dietary habits, and exercise habits.
METHODS
The participants were 65 elementary school children, of which 32 were assigned for the experimental group and 33 for the control group. The experimental group received an 8 weeks obesity management program. The outcome variables were measured before and after the program. chi2-test and t-test were used to analyze the data.
RESULTS
After the obesity management program, the BMI and fat mass percentage in the experimental group were significantly reduced. The score for dietary attitudes and dietary habits changed in a positive direction.
CONCLUSIONS
The findings from this study suggest that the obesity management program was effective in decreasing the rate of obesity and increasing the score for dietary attitudes and dietary habits. The program should be effective in the management of obesity in elementary school children.
