O objetivo deste estudo foi avaliar fatores associados ao uso de medicamentos por idosos. Foi realizado um inquérito postal nacional, com 3 mil idosos, selecionados com base no cadastro do Instituto Nacional do Seguro Social. Foram estimadas a prevalência e a média de medicamentos utilizados nos 15 dias anteriores à pesquisa, segundo faixas etárias.

A national postal survey was conducted with a random sample of 3,000 elderly individuals selected from the registry of the Brazilian National Social Security Institute. The study estimated the prevalence and average number of medicines used in the 15 days prior to the survey, according to age bracket. Prevalence of use of medication was 83.0%: 78.8% in the 60-69 year bracket and 87.3% in individuals 70 years or older (p < 0.05). Older elders had taken an average of 4.4 drugs, as compared to 3.3 among younger elders. Drugs for the cardiovascular system were the most widely used. Age 70 years and older, female gender, poor self-rated health, interruption of routine daily activities, six or more medical visits in the previous year, private health insurance, and reporting of four or more illnesses were independently associated with use of medications (p < 0.05). The results expand the knowledge on use of medications among elderly Brazilians, emphasizing the need to improve pharmaceutical care focused on this subgroup of the population.
