The purpose of this study was to examine the effect of body image distortion on health behaviors practice in high school students.

This study used a secondary data analysis study with the data derived from the 2019 Korea Youth Risk Behavior Web-based Survey. The study sample included 20,787 high school students. Collected data were analyzed with SPSS program using Rao-Scott x ² test and complex samples general linear model analysis.

The prevalence of adolescents with body image distortion was 24.5% in this study. Health behaviors practice had significant differences according to body image distortion (t=10.29, p<.001), and the score for health behaviors practice in adolescents with body image distortion was lower than those without body image distortion. Gender, grade, school type, school achievement, economic status, and perceived health state were found to be significantly related to health behaviors practice. After controlling significant variables, body image distortion (b=.14, p<.001) was significantly related to health behaviors practice in adolescents, accounting for 4.0% of the variance in health behaviors practice (Wald F=52.75, p<.001).

These findings suggest that body image distortion has negative effects on health behaviors practice and healthcare professionals need to consider enhancing body image for improvement of health behaviors practice in adolescents.

The purpose of this study was to examine the self-control, depression, and eating attitude according to weight control behaviors, and to develop intervention for education and counseling for weight control of female college students and healthy weight control behaviors.

It was cross-sectional descriptive study conducted for female college students. A total of 376 completed responses were collected and analyzed. Data were analyzed using descriptive statistics and a linear model using demographic characteristics as a control variable.

This study were as follows. The self-control was higher in the cases of regular exercise and reducing of meal than fast or meal skip in the main weight control behavior. The risk of eating disorder in fast or meal skip was higher than that of reducing of meal.

Based on these results, it is necessary to implement customized education and counseling according to weight control behaviors for healthy weight control behavior. A program should be planned to improve self-control, reduce depression, and manage the risk of ingestion disability for the fast or meal skip group.

The current study aimed to investigate the reliability and validity of the Self Rated Abilities for Health Practices: Health Self-Efficacy Measure (SRAHP), originally developed by Becker et al. (1993).

Two hundred and seventy-eight college students participated in this study.

The inter-item reliability was high (Cronbach alpha=0.909). Factor analysis produced 6 factors of subscales (i.e., exercise, illness, emotion, nutrition, stress, and health practice subscales), which is more ramified compared to original study with 4 subscales (i.e., exercise, well-being, nutrition, health practices). The correlation analyses between K-SRAHP and the self-promoting lifestyle profile, the generalized self-efficacy scale, the perceived benefits scale, and the social desirability scale supported criterion-related validity.

The reliability and validity of K-SRAHP to measure self-efficacy of health practice was validated. Additionally, the limitations and suggestions for further studies were provided.
