Association between levels of physical activity and use of medication among older women

Abstract

The aim of this study was to determine the association between levels of physical activity and usage of medication in older women. The level of physical activity was assessed using a pedometer. Use of medication was assessed through medical records supplied in reports kept by the Family Health Program, City Health Department, São Caetano do Sul, São Paulo State, Brazil. Regular use of pharmaceuticals, regardless of type of illness or treatment, was listed. Data analysis was performed using Poisson regression to estimate the prevalence ratio. The results of the study indicated that, amongst the 271 eligible women, 84.9% had been classified as active. Only 23.2% did not use any type of medication while 29.8% used three or more medications. The level of physical activity was inversely associated with the number of medications used, under both crude analysis and after adjustment. The study concluded that higher volumes of physical activity were significantly associated with lower usage of pharmaceuticals in women who are involved in a physical activity program.
