Temporal and spatial convergence: the major depressive disorder burden attributed to intimate partner violence against women

Le résumé fourni par la source

Background: There is a strong causal relationship between intimate partner violence and major depressive disorder, which partly endangers women's safety across the life course and potentially affects the development of future generations. The international community has placed a high priority on addressing the intimate partner violence and the resulting burden of mental illness. Data collection needs to be captured across the temporal trend and spatial distribution for major depressive disorder attributed to intimate partner violence, to reflect the priorities and expectations of survivors.Method: This research obtained raw disability-adjusted life years (DALYs) information for major depressive disorder attributed to intimate partner violence from the Global Burden of Disease 2019. Using estimated annual percentage change and two-way fixed effects models, a secondary spatio-temporal analysis of the age-standardized DALYs rate from 1990 to 2019 was performed.Results: In 2019, DALYs lost among women experiencing major depressive disorder (3.16 million) accounted for 37.18% of the DALYs lost worldwide due to intimate partner violence. The age-standardized DALYs rate of major depressive disorder attributed to intimate partner violence was 108.57 per 100,000. The highest was concentrated in the menopausal transition (45-55), with 133.61 per 100,000, and particularly distributed in Uganda (429.31 per 100,000). The early reproductive period (15–19) showed the increasing age-standardized DALYs rate from 1990 to 2019, which was mainly driven by Malaysia (3.73% per year). Furthermore, countries with higher initial levels of the age-standardized DALYs rate were growing faster than those with lower levels.Conclusions: The burden of major depressive disorder attributed to intimate partner violence showed biological and spatial inequality, prioritized intervention should be targeted at vulnerable stage women in their early reproductive period and menopausal transition. Combined political, socio-cultural as well as medical measures to prevent violence and treat major depressive disorder should be implemented and developed.
