Associations of psychological distress with unhealthy dietary behaviours among adolescents, overall and by region. Multi-level mixed-effect logistic regressions were adjusted for age, sex, low socioeconomic status, survey year, close friend, bullying, parental support, peer support, cigarette smoking, physical activity, and overweight. Odds ratios (ORs) are represented by squares, and their corresponding 95% CIs are represented by lines. The area of each square is inversely proportional to the variance of the logarithm of the corresponding OR estimates, which shows the amount of statistical information involved with the estimates.
