Burden and Correlates of HIV, Coinfections, and Risk Behaviors among Prison Inmates: Evidence from HIV Sentinel Surveillance in Three States of India.

Abstract

Background: The global prison population exceeds 11.5 million, with a 3% Human immunodeficiency virus (HIV) infection rate, significant burden of Hepatitis C, and risk of undiagnosed infectious diseases due to limited prior healthcare access. On release, prisoners may reintegrate into society, contributing to the spread of infections.

Objectives: To estimate the burden and correlates of HIV, coinfections, and risk behaviors among prison inmates in three Indian states.

Materials and methods: This study utilizes data from the 17 th round of HIV Sentinel Surveillance Plus 2021, among prison inmates in Chhattisgarh, West Bengal, and Nagaland. Participants were interviewed using a structured questionnaire, and blood specimens were tested for HIV, Syphilis, Hepatitis B virus (HBV), and Hepatitis C virus (HCV). Data were analyzed using STATA version 17. Stratified data analysis was done employing Pearson Chi-square testing. Factors associated with HIV and any infection were assessed with multivariable logistic regression analysis controlling sociodemographic factors as potential confounders.

Results: Nagaland records the highest HIV (4.6%), Syphilis (3.6%), and HCV (1.0%), and West Bengal has the highest HBV burden (1.5%). Logistic regression revealed higher odds of HIV infection among those with a history of imprisonment, undertrial status, and good HIV knowledge. The burden of any infection was higher in the 30-39 age group and those with a prior history of imprisonment.

Conclusion: This study highlighted the interplay between sociodemographics and high-risk behaviors within prison settings and the concentrated HIV epidemic. The findings should drive actionable strategies, guiding strategic planning, intervention prioritization, and resource allocation to enhance overall public health outcomes beyond prison confines.
