Injecting drug use is associated with HIV risk perception among Mexican Americans in the Rio Grande Valley of South Texas, USA

Summary Objectives Injecting drug use (IDU) remains an actual risk variable in human immunodeficiency virus (HIV) infection in most ethnic populations, and the association between actual risk and individual perception of HIV risk varies across studies and samples. This study aimed to examine the relationship between IDU and HIV risk perception among Mexican Americans residing in Rio Grande Valley, South Texas. Study design A cross-sectional study of IDU as a predictor of HIV risk perception. Methods Two hundred and seventy-five participants [IDUs 11.9%, non-IDUs 88.1%] were assessed for an association between IDU and individual risk perception for HIV infection, as well as history of drug use and HIV risk perception, using Chi-squared statistic for independence and a logistic regression model for the prevalence odds ratio (POR). Results There was no statistically significant difference between IDUs and non-IDUs with respect to the sociodemographic variables, except for income and gender ( P
