Abstract

This longitudinal study investigates the relationship between maternal depressive symptoms and the development of unhealthy behaviors in adolescents over a 15-year period. Utilizing a sample of 500 motheradolescent pairs, data were collected at multiple time points, assessing maternal depressive symptoms through standardized questionnaires and adolescent behaviors, including substance use, unhealthy eating habits, and risky sexual behavior. The findings reveal a significant association between persistent maternal depressive symptoms and an increase in various unhealthy behaviors in adolescents. Additionally, the study identifies mediating factors such as parental involvement, family dynamics, and socioeconomic status that contribute to the observed relationship. These results underscore the importance of addressing maternal mental health as a critical factor in promoting healthier behaviors among adolescents.
