RESUMEN
PURPOSE: Our study aims to evaluate the global burden of disease attributable to IPV from 1990 to 2019 at global, regional, national, and socio-demographic index (SDI) levels. Our research question is: What is the global burden of disease attributable to intimate partner violence (IPV) from 1990 to 2019, and how does it vary at global, regional, national, and socio-demographic index (SDI) levels? METHODS: Data parameters for the number of deaths, disability-adjusted life years (DALYs), and age-standardized rate were obtained from the Global Burden of Disease Study 2019. We calculated the percentage change and population attributable fraction with 95% uncertainty intervals. RESULTS: IPV directly accounted for 0.14% [95% UI 0.09%, 0.21%] and 0.32% [95% UI 0.17%, 0.49%] of global all-cause deaths and DALYs in 2019, respectively. The age-standardized deaths and DALYs rates of IPV increased by 12.83% and 4.00% respectively from 1990 to 2019. Women aged 35-39 and 30-34 had the highest deaths and DALYs rate respectively. The highest age-standardized rates of IPV-related deaths and DALYs were observed in Southern Sub-Saharan. Both of deaths and DALYs were high in low-socio-demographic Index (SDI) quintile in 2019. CONCLUSIONS: A higher level of deaths and DALYs attributable to IPV were reported in younger women, in the early 2000s, in Southern Sub-Saharan regions and in low SDI regions. Our study provides policymakers with up-to-date and comprehensive information.
RESUMEN
Background: The prevalence of mental distress is common for medical students in China due to factors such as the long duration of schooling, stressful doctor-patient relationship, numerous patient population, and limited medical resources. However, previous studies have failed to provide a comprehensive prevalence of these mental disorders in this population. This meta-analysis aimed to estimate the prevalence of common mental disorders (CMDs), including depression, anxiety, and suicidal behaviors, among medical students in China. Methods: We conducted a systematic search for empirical studies on the prevalence of depression, anxiety, suicide attempt, suicide ideation, and suicide plan in Chinese medical students published from January 2000 to December 2020. All data were collected pre-COVID-19. The prevalence and heterogeneity estimations were computed by using a random-effects model and univariate meta-regression analyses. Results: A total of 197 studies conducted in 23 provinces in China were included in the final meta-analysis. The prevalence data of depression, anxiety, suicide attempt, suicide ideation, and suicide plan were extracted from 129, 80, 21, 53, and 14 studies, respectively. The overall pooled crude prevalence for depression was 29% [38,309/132,343; 95% confidence interval (CI): 26%-32%]; anxiety, 18% (19,479/105,397; 95% CI: 15%-20%); suicide ideation, 13% (15,546/119,069; 95% CI: 11%-15%); suicide attempt, 3% (1,730/69,786; 95% CI: 1%-4%); and suicide plan, 4% (1,188/27,025; 95% CI: 3%-6%). Conclusion: This meta-analysis demonstrated the high prevalence of CMDs among Chinese medical students. Further research is needed to identify targeted strategies to improve the mental health of this population.
