Background: The prevalence of HIV among young people aged 15–19 years in Nigeria is estimated as 3.5%, the highest among West and Central African countries. Comprehensive knowledge of HIV is associated with increased awareness of preventive interventions and a reduction in the spread of HIV. Therefore, this article seeks to assess and determine the associated factors of comprehensive HIV knowledge among youths in Nigeria.

Methods: The study used the 2018 Nigerian Demographic Health Survey, a cross-sectional survey that employed a two-stage cluster sampling method. Comprehensive knowledge of HIV was assessed based on five questions. The data were analysed separately for men and women aged 15–24 years. A multivariable log-binomial regression model was used to determine factors associated with comprehensive HIV knowledge. All analysis was performed using Stata 15.0 and adjusted for weighting, clustering and stratification.

Results: A total of 15,267 women and 4019 men aged 15–24 years were included in this study. The prevalence of comprehensive knowledge of HIV was higher among women than among men (42.6% versus 33.7%; p < 0.001) and lower among younger ages 15–17 years compared with other ages. The findings revealed that age, ethnicity, wealth, education and exposure to mass media were statistically significant factors associated with comprehensive knowledge of HIV. In addition, religion, place of residence, phone ownership, internet use, currently working and having initiated sex were significant factors among women and modern contraceptive use among men.

Conclusion: Key findings from this study imply that public health programmes in Nigeria should focus on providing information on HIV/AIDS using different approaches, including comprehensive sex education as well as health promotion and education strategies in the formal and informal sectors. Because media exposure is a common and cost-effective way of public health promotion and education in modern times, emphasis could also be placed on using this channel to reach the target population.
