ABSTRACT

OBJECTIVE: Incident HIV infections in pregnant and breastfeeding mothers pose significant challenges to prevention of mother-to-child HIV transmission efforts in sub-Saharan Africa. We identified the predictors of willingness to self-test for HIV when retesting in pregnancy and postpartum among antenatal clients in a tertiary hospital in Northern Nigeria.

METHODS: Structured and validated questionnaires were administered to a cross section of antenatal attendees (n = 370) in March 2021. Willingness to self-test and adjusted odds ratios of potential predictors were generated from logistic regression models.

RESULTS: Of the 317 respondents who agreed to repeat HIV test during pregnancy, 29.3% (n = 93) were willing to self-test. Similarly, of those (n = 350) willing to retest after delivery, 27.4% (n = 96) were willing to self-test. Willingness to self-test during pregnancy was higher among respondents who were multiparous (2-4 births) (adjusted odds ratio, aOR = 2.40, 95% confidence interval CI, 1.14-6.43), employed (aOR = 1.49, 95% CI, 1.13-4.53) and those with at least secondary education (aOR = 2.96, 95% CI, 1.43-11.47). In contrast, willingness to self-test was lower among those who were unaware of the husband’s HIV status (aOR = 0.05, 95% CI, 0.02-0.13). Willingness to self-test after delivery was higher among respondents who were married (aOR = 15.41, 95% CI, 3.04-78.2), multiparous (aOR = 2.01, 95% CI, 1.27-5.63), employed (aOR = 1.59, 95% CI, 1.08-2.35) and had at least to secondary education (aOR = 6.12, 95% CI, 1.36-27.47). In contrast, willingness to self-test postpartum was lower among those who booked late (≥29 weeks) (aOR = 0.11, 95% CI, 0.022-0.52), those who were unaware of the risk of HIV transmission during breastfeeding (aOR = 0.29, 95% CI, 0.12-0.68) and participants who were unaware of the husband’s HIV status (aOR = 0.076, 95% CI, 0.03-0.19).

CONCLUSION: Willingness to self-test for HIV in pregnancy and postpartum was low in this population and was influenced by risk perception, socio-demographic and obstetric attributes. Communication interventions and training of potential mentor mothers among early adopters could improve self-testing in this group and similar settings.
