HIV and its associated factors among people who inject drugs in Mizoram, Northeast India

Abstract

Aim To estimate the prevalence and associated factors with the human immune-deficiency virus (HIV) among people who inject drugs (PWID) in Mizoram, Northeast India. Methods The data source for the analysis was the 2019–2020 Mizoram State AIDS Control Society (MSACS) survey from 2695 PWID registered for the Targeted Intervention (TI) services. Logistic regression analysis was conducted to examine the factors associated with HIV among PWID after adjusting for sociodemographic characteristics, injection, and sexual behaviours. Results 21.19% of the participants tested positive for HIV and the prevalence of HIV among male and female participants were 19.5% and 38.6%, respectively. Multiple logistic regression analysis revealed that female (AOR 1.74; 95% CI 1.26–2.41), 35 years or older (AOR 1.45; 95% CI 1.06–1.99), married (AOR 1.41; 95% CI1.08–1.83), divorced/separated/widowed (AOR 2.12; 95% CI 1.59–2.82) and sharing of needle/syringe (AOR 1.62; 95% CI 1.30–2.00) were all positively associated with HIV infection. We also found that concomitant alcohol use was reduced by 35% (AOR 0.65; 95% CI 0.51–0.82) among HIV positive PWID, and HIV infection was also reduced by 46% (AOR 0.54; 95% CI 0.44–0.67) among those PWID who use a condom with a regular partner. Conclusion The findings of this study suggested that there is a high prevalence of HIV among PWID with 1 in 5 PWID reported to have HIV. HIV among PWID was significantly higher among those over 35 years of age, females and divorced/separated/widowed participants. Needle/syringe sharing behaviour is an important determinant of HIV infection. The high prevalence of HIV among PWID population is multifactorial. To reduce HIV among PWID in Mizoram, interventions should target those sharing needles/syringes, females, especially those over 35 years of age and unmarried participants.

Finding a way forward with the community: qualitative inquiry in the generalized HIV epidemic in Mizoram, India

“…Thus, drug-sex interface between men and women surfaced as an intervention area requiring urgent attention. This was also revealed in a recent study from Mizoram (19). Young age were at onset of injecting drugs, as revealed by the present study and by other researchers, and during analysis of the National Integrated Bio-Behavioral Survey (IBBS) 2014-2015 (20,21) and unsafe sexual practices, such as inconsistent condom use during casual and commercial sex, were individual-level risk behavior.…”

High Diversity and Transmission Dynamics of HIV-1 Non-C Subtypes in Bangladesh

“…According to reports, 25–40% of new HIV infections in various Asian countries are caused by the wives and girlfriends of males who acquired the virus through paying women for sex, engaging in sexual activity with other men, or injecting drugs with non-sterile needles or syringes [ 5 , 6 ]. In addition, in many Asian countries, HIV has been detected among returnee migrants who acquire the infection while abroad and then transmit the virus to the local population [ 7 , 8 ].…”
