ABSTRACT
Injection users are at risk for vascular injuries resulting in chronic venous disease (CVD). The authors examined walking mobility in relation to CVD for 713 individuals in methadone treatment. The authors used a cross-sectional, comparative design that was stratified on age, sex, ethnicity, and drug use. CVD was present in 92.3% of participants. The structural equation model supported the causal link between leg injection and CVD (.40, P<.001). The worse the mobility, the greater was the CVD classification (−.21, P<.001). CVD had an indirect effect on mobility through pain. CVD and pain need to be considered when assessing mobility in illicit drug users.
