title: The impact of vascular leg disorders on physical activity in methadone-maintained adults.
abstract: Chronic venous disorders (CVD) and peripheral arterial disease (PAD) may affect diverse physical activity domains. How CVD and PAD and other relevant variables affect physical activity was examined in 569 opioid-addicted adults. Both CVD and PAD were significantly inversely related to daily walking, sports, and active living. Effects remained significant in the latent variable regression after controlling covariates. Overall activity was very low; most participants walked less than a half mile daily and rarely engaged in sports. Motivation for physical activity was the strongest predictor (β = .55) of daily physical activity. Health-care professionals promoting physical activity for injection users should consider the vascular health of their legs and motivational variables in addition to general health.
