Depressive disorders attributable to childhood sexual abuse and bullying victimization: Temporal trends and socio-demographic inequalities.

BACKGROUND

Childhood sexual abuse and bullying victimization are critical risk factors for depressive disorders, contributing significantly to the global health burden. This study evaluates the global, regional, and national burden of depressive disorders attributable to these factors from 1990 to 2021, focusing on trends, age and sex disparities, and socio-demographic inequalities.

METHODS

Using Global Burden of Disease 2021 data from 204 countries, we measured the burden in disability-adjusted life years (DALYs) with 95 % uncertainty intervals (UI). Temporal trends were assessed via estimated annual percentage change (EAPC), with COVID-19-related changes represented by percentage change. Socio-demographic influences were examined using the Socio-demographic Index and inequality indices. Future trends were forecasted using Bayesian models.

RESULTS

The global age-standardized DALYs rate (ASDR) for depressive disorders attributable to childhood sexual abuse was 18.08 (95 % UI: 8.75-30.97) per 100,000 population, while bullying victimization accounted for 44.32 (95 % UI: 18.72-83.89). From 1990 to 2021, the burden linked to childhood sexual abuse decreased, whereas bullying victimization steadily increased. Females experienced a higher burden from childhood sexual abuse, while bullying-related depressive disorders peaked in males aged 15-24. In 2021, depressive disorders attributable to childhood sexual abuse displayed negative slope index of inequality values (-14.42, 95 % confidence intervals: -19.04 to -9.80). By 2035, ASDRs for both factors are projected to increase by 37-50 %.

CONCLUSIONS

This study highlights the substantial burden of depressive disorders due to childhood trauma, emphasizing the need for tailored interventions, equitable mental health care, and global collaboration to address these challenges.
