HIV and AIDS-related knowledge, HIV risk perception, uptake of HIV testing and its predictors among prison inmates in Bauchi State, Nigeria: a cross-sectional study

INTRODUCTION: globally, HIV infection among prison inmates is significantly higher than in the general population. Therefore, it is important to identify inmates-living-with-HIV, through HIV-testing, in keeping with the target of UNAIDS vision 90-90-90. We assessed HIV/AIDS-related knowledge, HIV-risk perception and predictors of HIV-testing-uptake in Bauchi Prison. METHODS: we conducted a cross-sectional study among 310 inmates selected with 2 stage sampling. Data was collected using a pretested, structured, interviewer-administered questionnaire. Inmates that consented to HIV-test were tested. We estimated inmates' knowledge about HIV/AIDS, the level of HIV testing uptake and predictors of HIV testing-uptake using multiple logistic regression at 5% significant level. RESULTS: the mean age (SD) was 32.3 (±9.4) years and 94.8% were males, 47.1% (95% CI: 41.6-52.7) of the respondents had good knowledge of HIV/AIDS. Fifty-five percent (95% CI: 49.9-60.9) felt they were not at risk of contracting HIV. Uptake of HIV-testing was 58.1% (95% CI: 52.5-63.4). Independent predictors for the uptake of HIV-testing were age 35-44 years (aOR= 3.3; 95% CI: 1.4-7.7), positive risk perception (aOR= 3.3; 95% CI: 1.8-6.2), good knowledge of HIV (aOR= 9.6; CI: 5.1-18.0) and knowing someone who had died of AIDS (aOR= 4.1; 95% CI: 1.9-6.4). CONCLUSION: good knowledge of HIV/AIDS and HIV-testing-uptake was low among the inmates. We recommended the development and implementation of targeted HIV-testing interventions that cater to the specific needs of different age-groups within the prison population. The prison authority should develop prison-specific health education programme and awareness campaigns aimed at promoting accurate HIV-risk perception, improving their knowledge and help inmates make informed decisions that will prevent them from contracting HIV.
