Background : The current physical activity guidelines recommend engagement in strength activities at least 2 days per week. Currently, there is a lack of literature examining strength activities among people with disabilities. The purpose of this study is to estimate and compare the prevalence of engagement in strength activities and adherence to strength activity guidelines among adults with and without disabilities in the United States. Methods : A total of 1,005,644 adults (18–80 y old) with and without disabilities from the 2013 to 2017 Behavioral Risk Factor Surveillance System were included in this secondary data analysis. Descriptive analyses were performed to describe the prevalence of strength activity behaviors of adults with and without disabilities. Logistic and Poisson regression models were performed to evaluate the relative contribution of disability status on strength activity behaviors. Results : A higher proportion of participants without disabilities (46.42%, 95% CI, 46.18–46.65) reported engaging in strength activities compared with participants with disabilities (30.68%, 95% CI, 30.29–31.08; P < .01). Participants with disabilities were less likely to engage in strength activities (odds ratio = 0.51, 95% CI, 0.50–0.52; adjusted odds ratio = 0.75, 95% CI, 0.73–0.77) and meet strength activity guidelines (odds ratio = 0.56, 95% CI, 0.54–0.57; adjusted odds ratio = 0.75, 95% CI, 0.73–0.77) than participants without disabilities. Conclusion : Experiencing a disability is associated with lower engagement in strength activities; thus, it is important to identify effective and efficient approaches to promoting strength activities among people with disabilities.
