Factors associated with history of HIV testing among pregnant women and their partners in Cameroon: baseline data from a Behavioral Intervention Trial (ANRS 12127 Prenahtest).

Background: We investigated HIV testing practices at baseline among pregnant women and their partners within a multicountry randomized trial aiming to evaluate the effect of enhanced prenatal posttest HIV counseling on men's involvement.

Methods: In Yaoundé, Cameroon, 484 pregnant women with stable partners were recruited on their first antenatal care visit. We analyzed the coverage of previous HIV testing among women and their partners and looked for the factors associated with previous HIV testing, using multivariable logistic regression.

Results: Among 476 pregnant women who completed the baseline questionnaire, 408 (85.7%) reported having been tested for HIV already once in their life, 48.3% of them during a previous pregnancy. Women previously tested for HIV were more likely to be in a stable relationship for >5 years than those never tested (P < 0.001). In multivariable analysis, tested women were more likely to be aged between 25 and 30 years compared with women <20 years [odds ratio (OR) 5.5, 95% confidence interval (CI): 1.4 to 22.1], to be able to say whether they felt at risk for HIV infection (OR 2.1, CI: 1.1 to 3.9), and to have ever discussed about HIV with their partner (OR 2.7, CI: 1.1 to 6.4). Most women (85.1%) reported that their partner had already been tested for HIV. Reasons for partner HIV testing were related to self-motivation (30.0%) and clinical symptoms (12.7%).

Conclusions: Strategies aiming at improving knowledge and couple communication about HIV risks need to be considered to address the remaining barriers to HIV testing and contribute to a couple approach to HIV prevention.
