[Common mental disorders and social support in a rural community in Zona da Mata, Pernambuco State, Brazil].

The objective of this study was to determine the prevalence of common mental disorders and the association with social support in a community located in the Zona da Mata, a sugar cane plantation area in the State of Pernambuco, Brazil. A household survey was carried out and the Self-Reporting Questionnaire (SRQ-20), the Medical Outcomes Study, and socioeconomic questions were administered to all residents over 19 years of age. Total prevalence of common mental disorders was 36.0%. Multivariate logistic regression analysis showed that individuals with low social support had twice the probability of suffering from common mental disorders (OR: 2.09; 95%CI: 1.35-3.24) as compared to those with greater support, even after adjusting for age, schooling, and work force participation. The results show the importance of investments in social support networks to promote interactions between individuals and increase individuals' self-confidence and power to deal with problems.
