COSTA, Karen Sarmento et al. Use of medication and associated factors: a population-based study in Campinas, São Paulo State, Brazil. Cad. Saúde Pública [online]. 2011, vol.27, n.4, pp.649-658. ISSN 1678-4464. http://dx.doi.org/10.1590/S0102-311X2011000400004.
This article analyzes prevalence rates in the use of medication according to demographic, socioeconomic, and health-related behavioral variables through a population-based cross-sectional study of individuals 18 years and older (n=941) in Campinas, São Paulo State, Brazil. The study used multistage sampling, both stratified and cluster. Chi-square test was performed, and adjusted prevalence ratios were estimated by gender and age, both with 95% confidence intervals. A Poisson multiple regression model was developed, and the following factors were associated with use of medication: female gender, age 40 and over, reported illness in the previous two weeks, and number of chronic diseases. The most widely consumed drugs were for the cardiovascular and nervous systems, besides herbal remedies. Prevalence of medication in Campinas was lower than in most studies. Local health surveys could help identify drug use patterns and guarantee more appropriate interventions for pharmaceutical care policy.
