OBJECTIVE: To analyze factors associated with low adherence to drug treatment for chronic diseases in Brazil. METHODS: Analysis of data from Pesquisa Nacional sobre Acesso, Utilizacao e Promocao do Uso Racional de Medicamentos (PNAUM - Brazilian Survey on Access, Use and Promotion of Rational Use of Medicines), a population-based cross-sectional household survey, based on a probabilistic sample of the Brazilian population. We analyzed the association between low adherence to drug treatment measured by the Brief Medication Questionnaire and demographic, socioeconomic, health, care and prescription factors. We used Poisson regression model to estimate crude and adjusted prevalence ratios, their respective 95% confidence interval (95% CI) and p-value (Wald test). RESULTS: The prevalence of low adherence to drug treatment for chronic diseases was 30.8% (95% CI 28.8-33.0). The highest prevalence of low adherence was associated with individuals: young adults
no education
resident in the Northeast and Midwest Regions of Brazil
paying part of the treatment
poor self-perceived health
three or more diseases
reported limitations caused by a chronic disease
using five drugs or more. CONCLUSIONS: Low adherence to drug treatment for chronic diseases in Brazil is relevant, and regional and demographic differences and those related to patients' health care and therapy regime require coordinated action between health professionals, researchers, managers and policy makers.
