The objective of this study was to investigate the prevalence of polypharmacy and the association between medication use and cognitive impairment among elderly residents in the community. 1.554 (from a total of 1.606) participants of Bambuí baseline cohort were enrolled in the study. Cognitive function was evaluated by Mini-mental Exam State (MEM).The analysis of data was based on the ordinal regression model. The prevalence of polypharmacy (2+ medicines used) was 70.4% and the number of medicines used presented a negative and independent association with cognitive impairment (OR=0.72; CI95% 0.55-0.95). When this association was stratified for personal income (<2 Minimum Wage versus 2 Minimum Wage), it was observed a negative association between medication use and cognitive impairment among elderly with low income (OR=0.64; CI95% 0.48-0.86), but not among those of high income (OR=1.74; CI95% 0.81-3.74). With reference to the association between cognitive impairment and number of medicines used, the results indicate social inequality in the use of medication. It is possible that those elderly are not consuming the necessary medicines to the appropriate treatment of your health problems
