Health related quality of life among elderly living in region of high vulnerability for health in Belo Horizonte, Minas Gerais, Brazil.

OBJECTIVE To investigate whether social relations, sociodemographic characteristics, lifestyle, and health conditions are associated with health-related quality of life (HRQOL) among elderly persons living in regions classified as high vulnerable in terms of health. METHODS A cross-sectional study conducted with a population-based random sample of 366 elderly (≥ 60 years of age) persons registered at a primary health-care unit in Belo Horizonte, Minas Gerais, Brazil. HRQOL was measured using the Medical Outcomes Study 12-Item Short-Form Health Survey (SF-12) and the scores obtained in the physical component score (PCS) and mental component score (MCS) were our response variables. Social relations, sociodemographic characteristics, lifestyle, and health conditions were considered our groups of explanatory variables. Multiple linear regression models were used for the analysis. RESULTS In the final multivariate models, we found that elevated number of diagnosis of chronic diseases, and being bedridden for the last 15 days were variables associated with worse PCS and MCS. However, lack of education, dissatisfaction with personal relationships, lack of support and help when bedridden or to go to the doctor, and to prepare meals were associated with worse HRQOL only in MCS. Participants who reported black race/color, absence of work activity, lack of physical activity, no alcohol consumption, and hospitalization in the last 12 months had worse HRQOL only in PCS. CONCLUSION In addition to the aspects related to social adversity, lifestyle, and health conditions, some functional aspects of social relations were important for understanding the HRQOL in elderly persons living in social vulnerability.
