Abstract:
Mood disorders are a consequence of the interaction between environmental and biological factors. The objective of this study was to identify associations between stressful life events (LEs) and mood disorders in a community sample of young people in southern Brazil. It is a cross-sectional population-based study on young people between 18 and 24 years of age. The selection of the sample was conducted via conglomerates. Mini International Neuropsychiatric Interviews were used to evaluate mood disorders, and the Social Readjustment Rating Scale to assess stressful life events. The sample included 1172 young people. Of the total sample, the proportion of stressful life events in the last year in each category was: 53.8% work, 42.4% loss of social support, 63.8% family, 50.9% environmental changes, 61.1% personal difficulties, and 38.7% finances. A significant relationship was found between categories of stressful life events and mood disorder episodes. A higher incidence of stressful life events was found among young people in a mixed episode compared to young people in a depressive, (hypo)maniac episode with controls. This finding suggests a psychosocial interaction between stressful life events and the occurrence of mood disorders.
