Notes: Predicted probabilities (in %) were obtained from ordered probit models controlling for body image stress, self-reported health status, father’s and mother’s education, household economic status, number of cars at home, having no bedroom for the student, number of computers at home, residence area type, school level, and survey year. Confidence Intervals are based on bootstrapped standard errors obtained from 1 000 replications.
