Concerns about contracting HIV, knowing partners' HIV sero-status and discussion of HIV/STI with sexual partners as determinants of uptake of HIV testing.

Worldwide, adolescents and young adults (aged 15-25 years) account for the highest proportion of new HIV infections, yet the uptake of HIV testing among this cohort is sub-optimal. Understanding factors that predict the uptake of HIV testing among adolescents and young adults is critical for designing effective and relevant interventions to increase testing. Drawing from the psychosocial constructs of the Health Belief Model, the study examined the effects of HIV risk perception, discussion of HIV with partners and knowing partners' HIV status on HIV testing uptake among adolescents and young adults in two Nigerian universities.
