Background
The purpose of the study was to assess the prevalence and associated factors of major depressive disorder (MDD), generalized anxiety disorder (GAD), and past 12-month suicidal behaviour (PSB) among adolescents in Mozambique.
Methods
Data from 3,109 females (aged 15–19 years) and 1,439 males (aged 15–19 years) that participated in the 2022-23 Mozambique Demographic and health Survey were analysed. MDD was assessed with the PHQ-9 and GAD with the GAD-7.
Results
Results indicate that among girls the prevalence of PSB was 4.3% (attempt 1.0%, plan 1.9% and/or ideation 3.6%) and among boys 2.5% (attempt 0.3%, plan 0.7% and/or ideation 2.4%). Among girls and boys, the prevalence of MDD (≥ 8 scores) was 15.5% and 3.7%, respectively, and the prevalence of GAD (≥ 5 scores) was 25.0% and 10.3%, respectively. In adjusted logistic regression analysis, among girls, GAD was positively and solid fuel use was negatively associated with PSB, while among boys MDD and urban residence were positively associated with PSB. Among female adolescents, currently being pregnant and “big problem to get money for medical treatment” increased the odds of MDD. While among male adolescents, urban residence, having a genital sore or ulcer, has living children, and early sexual debut were positively associated with MDD. Urban residence, current alcohol use, and early sexual debut were positively associated with GAD in male adolescents, while poorer wealth status, being pregnant, and having a “big problem to get money for medical treatment” were positively associated with GAD in female adolescents.
Conclusion
About 3% of participants had PSB, among girls one in five had MDD or GAD and among boys more than 5% had MDD or GAD. Public health interventions can be guided by several associated factors that have been identified.
