Abstract:

The objective of this article is to analyze the prevalence of polypharmacy and excessive polypharmacy , as well as its associated factors among the elderly attended at two Basic Health Units of Belo Horizonte, MG. Cross-sectional observational study performed through information resultinga structured interview to the patient. We analyzed the individual associations of each explanatory variable with polypharmacy and with excessive polypharmacy. For the variables that showed a significant association with polypharmacy, a multivariate analysis was performed using the logistic regression model. The elderly used, on average, 5.2 drugs. The prevalence of polypharmacy was 57.7% and excessive polypharmacy was 4.8%. In univariate analysis the variables associated with polypharmacy were: conditions age ≤70 years, schooling > 8 years, presence of more than three diseases and presenting symptoms of depression. For excessive polypharmacy, the presence of more than three diseases, self-perception of negative health, and partial dependence on instrumental activities of daily living were associated with conditions. In the final multivariate model for polypharmacy, the variables age ≤70 years and presence of more than three diseases remained.
