Prevalence and attributable risk of depressive and anxiety symptoms among secondary school students: the role of maternal mental health and other risk factors.

BACKGROUND

Depressive and anxiety symptoms among secondary school students have become significant public health concerns; however, comprehensive studies examining their prevalences and associated factors (particularly regarding the influence of maternal mental health) are limited.

METHODS

A cross-sectional study was conducted among 7850 secondary school students. The Patient Health Questionnaire-9, Generalized Anxiety Disorder-7, and Perceived Social Support Scale questionnaires were used to assess depressive symptoms, anxiety symptoms, and social support, respectively.

RESULTS

The self-reported prevalences of depressive and anxiety symptoms were observed to be 11.6% and 18.1%, respectively, among secondary school students. Multivariable analysis revealed significant risk factors, including female sex, suburban region, and maternal depressive and anxiety symptoms (all P < 0.001), along with parental discord, academic stress, insufficient physical activity, excessive screen time, and moderate household income (all P < 0.05). Population attributable risk (PAR) analysis revealed that academic pressure accounted for the greatest contribution to both depressive (PAR%=34.5%, 95% CI: 23.6-47.8%) and anxiety symptoms (PAR%=45.8%, 95% CI: 36.3-58.1%). Suburban residence (33.2% for depression, 45.0% for anxiety), insufficient physical activity (26.0% for depression), and excessive screen time (25.4% for depression, 21.0% for anxiety) were substantial contributors. Maternal anxiety symptoms explained 20.4% (95% CI: 15.7-25.7%) of the prevalence of depressive symptoms and 23.4% (95% CI: 18.8-28.6%) of the prevalence of anxiety, whereas maternal depressive symptoms contributed 12.9% (95% CI: 8.7-18.8%) to student depression despite demonstrating the strongest individual-level association (aOR = 5.497). Social support demonstrated a protective effect against both conditions (P < 0.05).

CONCLUSION

The findings highlight the considerable prevalences of depressive and anxiety symptoms among secondary school students and underscore the significant role of maternal mental health and other modifiable risk factors.
