Comportamentos em saúde e exames preventivos entre adultos filiados ou não a planos de saúde na Região Metropolitana de Belo Horizonte, Minas Gerais, Brasil, 2003-2010

This study analyzed indicators for health behaviors and use of preventive services in two probabilistic samples of adults, one in 2003 (n = 13,757) and the other in 2010 (n = 12,983), with and without private health insurance in Greater Metropolitan Belo Horizonte, Minas Gerais State, Brazil. After adjusting for demographic variables, temporal variation, and source of care, there was a reduction in smoking prevalence, similar between individuals with and without private health insurance, from 2003 to 2010. During this same period the prevalence of excessive alcohol intake and sedentary lifestyle increased in both groups; with the same magnitude, there was a decrease in the prevalence of leisure-time physical activity. No changes were observed in the prevalence of blood pressure measurement, but the prevalence of cholesterol testing, mammogram, and Pap smear increased more sharply in individuals without health insurance.
