Perceived Behavioral Control and Barriers to Cleaning Skin Before Injecting Drugs.

Abstract

Skin and soft-tissue infections (SSTI) among people who inject drugs (PWID) are common and represent a significant public health burden. In the current study, we examined the relationship between perceived behavioral control and perceived barriers to cleaning skin before injecting drugs. Participants (n = 248; 37.9 [±10.7] years of age, 58.5% male, 59.3% white, 16.1% Hispanic) were patients seeking medical care at a large urban hospital in the northeastern United States. We used ordinary least squares regression to estimate the associations between perceived barriers to skin cleaning with background characteristics and perceived behavioral control. Controlling for background and other study variables, greater number of past-year skin abscesses was associated with greater level of perceived barriers to skin cleaning (P < 0.001), whereas higher level of education and higher perceived behavioral control were associated with lower levels of perceived barriers to skin cleaning (P < 0.001). Interventions aiming to reduce the likelihood for SSTI among people who inject drugs may benefit from strengthening individual's behavioral control and providing skin cleaning skills training.
