Abstract:
Background and Aim : Background:: HIV testing plays an important role in any public health strategy for reducing HIV transmission and controlling the HIV/AIDS among PWIDs. It is important to clarify whether HIV risk behaviors are explained by differences in the distributions of sociodemographic or socio-economic factors or some combination of both. In this study, we used a Blinder–Oaxaca decomposition for non-linear models to explore the relative contributions of variations in the distributions of socio-demographic vs their differential effects in producing economic inequalities in HIV testing in Tehran.Methods : This study is a cross-sectional survey on PWIDs in 2016 in Tehran. Participants were reported injecting drug use in the past month, were able to speak and comprehend Farsi enough to respond to survey questions, and were able to provide informed consent to complete the interview. Income of the participants which was used as a proxy of economic status was the key explanatory variable. Economic status was measured by a composite index created by principal component analysis (PCA) using income information. we used Blinder– Oaxaca (BO) method to decompose the economic inequality in HIV testing.Results : A total of 520 people were interviewed for the study. Data for these analyses are limited to the 500 who fully completed the questionnaire. The proportion of never- married was 40%, 73.3% had less than 6 years of schooling. Almost one quarter (24%) of participants had a monthly income of more than 150 dollars and almost half (42%) reported more than 2 injections of illicit drugs per day. The most important factors in the explained component were Knowledge of HIV (6.2%) and access to NSP 4.2%). The lower level of knowledge of HIV in the low-economic group was the main factor responsible for the explained component.Conclusion : The results showed that economic inequalities in HIV/AIDS risk testing were primarily explained by the differential effects of access to harm reduction and HIV knowledge for low and high economic rather than by the differential distributions of these characteristics. Increasing access to harm reduction programs and in turn HIV knowledge inequalities are essential to efforts to eliminate HIV
