Assessment of condom use among Bolivian truck drivers through the lens of social cognitive theory.

This study demonstrates that Bolivian long distance truck drivers are a high risk population of HIV infection and transmission, supporting other global studies involving truck drivers and their high risk. The aims of this investigation were to estimate the prevalence of high risk behaviors and to identify predictors of condom use in this population. Analysis was completed on survey results from 246 male truckers (aged 18-67).
