BACKGROUND: The pathological significance of adolescent obesity is increasing, as research results indicate that about 80 percent of obese teenager becomes obese as adults. However, most studies on obesity have been mainly centered on the biomolecular aspect of obesity, thereby offering little solution to the clinical application and the promotion of overall health for people. This study investigates into the psychological factors of adolescent obesity, mainly that relating to stress. METHODS: After having chosen 14 third year classes from two middle schools, one from the Kang nam and the other from the Kang puk region of Seoul, I have distributed questionnaires to the total of 501 students. For calculating the degree of stress among the students, I have employed the BEPSI (Brief Encounter Psychosocial Instrument) K, transforming each 5 positive questions into 1 point, which were summed up and divided by 5 (the BEPSI K score). RESULTS: Controlling the confounding factor, the regression coefficient regarding the Body Mass Index of the BEPSI K score was 0.661, t as 3.122, and R Square as 0.05, indicating the statistical relevance of the two factors. A multiple linear regression analysis of theses data yielded the following equation: Body Mass Index=15.6+0.661 x BEPSI K score(R2=0.05) Although the R Squre, as 0.05, was relatively low, this statistical result proves that the rise in stress contributes to the increase of Body Mass Index, thereby indicating that stress functions as an important factor for adolescent obesity. CONCLUSION: For remedying and preventing adolescent obesity, one must make use of the BEPSI K examination and calculate the degree of stress among the adolescent. This study further implies that the best solution to the problems of obesity among adolescent is for the family members, the educational institutions, and the society as a whole to understand and to help the adolescent overcome frequent mental stress resulting from their daily living.
