Prevalence and predictors of unknown HIV status among women delivering in Mulago National Referral Hospital, Kampala, Uganda.

Introduction: Knowledge of a person's HIV status during pregnancy is critical for prevention of mother to child transmission of HIV. Objectives: To determine the prevalence and factors associated with unknown HIV status among women delivering in Mulago Hospital. Methods: This was a cross-sectional study of women that had just delivered. The women's demographic characteristics, health seeking behaviour, health system-related factors and knowledge on PMTCT were collected. Fisher's exact test, Wilcoxon rank sum test and logistic regression were used to test associations. Results: The prevalence of unknown HIV status was 2.6% (10/382). Attending ANC at higher level facilities (OR = 0.1 95% CI 0.0 -0.4) and having been counselled for HIV testing during ANC (OR= 0.1, 95% CI 0.0 -0.4) were associated with likelihood of having a known HIV status. Out of the ten women with unknown HIV status, 4/6 who attended ANC in public/government accredited health facilities "opted out" of HIV testing due to personal reasons. Among the four who attended ANC in private clinics, two were not offered HIV testing and one "opted out". Conclusion: Most participants had a known HIV status at labour (97%). Private clinics need to be supported to provide free quality HCT services in ANC.
