BACKGROUND: Prescription medication use and extended sedentary time are independently related to poor health outcomes (e.g., diabetes, metabolic syndrome, mortality). Historically, survey methods have been used to obtain estimates of total sedentary time (ST), however, recent use of accelerometers avoids self-report bias and affords more characteristics of ST that may be factors in health outcomes (e.g., frequency and duration of sedentary bouts). The aims of this pilot study were to 1) examine the association between objectively measured ST via accelerometers and self-reported prescription medication use in adults and 2) examine the independent association of sedentary bout length and frequency with prescription medication use.

METHODS: Adults (N=32) were asked to wear an accelerometer continuously on their right hip for seven days while manually recording sleep times and instances of activity monitor removal. Participants were also asked to report the number and type of medications they were currently prescribed. Poisson regression analysis was used to predict the number of prescriptions medications an individual consumed based on the average hours of ST per day, average number of bouts per day, and average time (min) of sedentary bouts.

RESULTS: Analysis revealed a significantly higher prevalence of prescription medications for each hour of ST per day (PR 1.66; 95% CI 1.25-2.19; P

CONCLUSIONS: Our findings suggest that increased sedentary time is associated with greater prescription medication use among adults.
