Abstract


Objectives: The purpose of this study was to examine the mediating effect of body image distortion on the relationship between body mass index and weight loss behaviors among underweight and normal weight adolescents.

Methods: Using statistics from 15th (2019) Korea Youth Risk Behavior Webbased Survey, Rao-Scott χ2 test and complex samples logistic regression was conducted. The study sample included 44,057 middle and high school students.

Results: Weight loss behaviors had significant differences according to body mass index and body image distortion. Gender, grade, school type, school achievement, economic status, and father’s and mother’s education levels were found to be significantly related to weight loss behaviors. After controlling general characteristics, body mass index was influenced to weight loss behaviors, and body image distortion partially mediated it (Z = 13.94, p< 0.001).

Conclusions: Findings suggest that it is crucial to perceive accurate body weight and to prevent body image distortion for the improvement of healthy weight control behaviors among underweight and normal weight adolescents.
