[Individual and family factors associated with depressive symptomatology in adolescents from public schools of Mexico].

Objective: To estimate the prevalence of depressive symptoms (DS) and to explore associated individual and family factors in high-school students from public schools of Mexico.
Materials and Methods: Cross-sectional study of a representative sample of 9 982 students aged between 14 and 19 years. Logistic regression models were used to estimate odds ratio (OR) with 95% confidence interval (CI95%).
Results: 27% of students presented DS, with higher proportion among women (34%) than among men (18%). Factors associated with DS were being female (OR=2.25 CI95% 1.86-2.71); low self-esteem (OR=2.77 CI95% 2.41 -3.19); consuming alcohol (OR= 1.72 CI95% 1.46-2.02), consuming tobacco (OR= 1.57 CI95% 1.31-1.88), consuming illegal drugs (OR=1.63 CI95% 1.29-2.05), domestic violence (OR=2.05 CI95% 1.77-2.39), and low communication between parents and their children (OR=1.78 CI95% 1.59-2.00).
Conclusions: Depressive symptomatology among high-school students in Mexico is a public health issue.There is a need for intervention programs aimed at tackling the associated risk factors.
