Contextual factors associated with rushed injecting among people who inject drugs in Thailand.

People who inject drugs (IDU) often rush their injections; however, the prevalence and predictors of rushing during injecting has not been well studied. We sought to identify correlates of rushed injecting among a community-recruited sample of IDU in Bangkok, Thailand. Data were derived from IDU who participated in the Mitsampan Community Research Project in Bangkok between July and October in 2011. Multivariate logistic regression was used to identify the prevalence and factors associated with frequent rushed injecting, defined as rushing injections at least 25 % of the time in the last 6 months. Among 437 participants, 27 % reported frequent rushed injecting. In multivariate analyses, factors positively and independently associated with frequent rushed injecting included: syringe sharing, injecting in public places, and having noticed increased police presence where drugs are bought or used. Many Thai IDU in this setting reported frequent rushed injecting and factors known to increase HIV risk were found to be associated with this behavior. These findings reinforce the need for public health interventions that address the broader social and physical risk environment where drug injecting takes place.
