title: The correlation of depression with Internet use and body image in Korean adolescents.
abstract: OBJECTIVE
  To examine the correlation of depression with Internet use and body image perception, and to analyze the risk factors of depression in a total of 920 students in Seoul, Korea.
  
  
  METHODS
  Students were recruited by contacting school principals and teachers and were encouraged to fill out a self-report questionnaire designed specifically for this study in July of 2008.
  
  
  RESULTS
  Female participants had an increased risk for depression than did male participants (adjusted odds ratio [aOR], 1.790; 95% confidence interval [CI], 1.330-2.410,P<0.001). Older students were more susceptible to depression (aOR, 1.246; 95% CI, 1.115-1.392,P<0.001). Longer daily Internet use and more frequent Internet use were analyzed as risk factors for depression. No physical activity was a risk factor for depression (aOR, 0.392; 95% CI, 1.264-4.526,P=0.014). Dissatisfaction with one's body image increased the risk for depression (aOR, 1.373; 95% CI, 1.169-1.613;P<0.001). Obesity and perception of body image showed no significant relationship with increased risk for depression.
  
  
  CONCLUSIONS
  Prevalence of depression was 13.8% in adolescents in Seoul, Korea, in July 2008. Female sex, age, daily Internet use duration, weekly Internet use frequency, physical activity, and dissatisfaction with one's body image independently increased risk of depression.
