Description
Summary:OBJECTIVE: To analyze published evidence from the Latin America and Caribbean (LAC) region pertaining to risk factors for completed suicide and suicide attempts among psychiatric populations. METHODS: Potential studies were identified through systematic electronic searches in MEDLINE and LILACS. Included studies were cohort, case-control, and cross-sectional designed investigations of psychiatric samples in which suicide or a suicide attempt was reported as an outcome and evaluated with some measure of impact (odds ratio, risk ratio, or hazard ratio). Methodological quality was assessed using the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) recommendations. RESULTS: Of the 2 987 identified studies, a total of 17 studies were reviewed to determine potential suicidal risk factors. Eleven studies used a case-control design, five used a cross-sectional design, and only one study used a prospective-cohort design. The main risk factors for suicide attempts in LAC included major depressive disorder (MDD), family dysfunction, and prior suicide attempt, while the main risk factors for completed suicide were male gender and MDD. The methodological quality of most of the studies was low. CONCLUSIONS: This review provides evidence that the majority of relevant risk factors for suicide and suicide attempts in the LAC region are similar to those observed in Western societies but different from those reported in Eastern societies. Studies of higher methodological quality from the region are needed to support these results.
