This study proposed to estimate the prevalence of behavioral disorders and associated factors in adolescents (11-15 years), using a cross-sectional design (n = 1,145). Subjects answered a self-administered questionnaire. Behavioral disorder was assessed with the Mini International Neuropsychiatric Interview (MINI). The study analyzed disorders in relation to gender, age, socioeconomic status, schooling, failure in school, religion, smoking, sedentary lifestyle, alcohol consumption, drug use, depression, and bullying (as victim). Ordinal regression was used for the statistical analysis, with a hierarchical model for the outcome. An estimated 29.2% of the sample presented behavioral disorders. In the multivariate analysis, the odds ratio for a male adolescent to present one additional point on the behavioral disorder scale was 2.04 (95%CI: 1.53-2.71). Alcohol consumption, drug use, and suffering bullying were associated with higher scores on the behavioral disorder scale. The findings also showed that the factors associated with behavioral disorder showed a strong interrelationship between health behaviors in adolescence.
