Abstract
Background
This longitudinal study explored the relationship between trajectories of maternal depressive symptoms and offspring’s risk behavior in adolescence contributing to an extremely scarce literature about the impacts of maternal depression trajectories on offspring risk behaviors.
Methods
We included 3437 11-year-old adolescents from the 2004 Pelotas Birth Cohort Study. Trajectories of maternal depressive symptoms were constructed using Edinburgh Postnatal Depression Scale (EDPS) from age 3 months to 11 years. We identified five trajectories of maternal depressive symptoms: “low” “moderate low”, “increasing”, “decreasing”, and “chronic high”. The following adolescent outcomes were identified via self-report questionnaire and analyzed as binary outcome –yes/no: involvement in fights and alcohol use at age 11. We used logistic regression models to examine the effects of trajectories of maternal depressive symptoms on offspring’s risk behavior adjusting for potential confounding variable.
Results
Alcohol use and/or abuse as well as involvement in fights during adolescence, were not significantly associated with any specific trajectory of maternal depressive symptoms neither in the crude nor in the adjusted analyses.
Conclusion
Alcohol use and involvement in fights at age 11 were not associated with any specific trajectory of maternal depression.
