Disclosure of one's HIV status can help to improve uptake and retention in prevention of mother-to-child transmission of HIV services; yet, it remains a challenge for many women. This systematic review evaluates disclosure rates among pregnant and postpartum women in sub-Saharan Africa, timing of disclosure, and factors affecting decisions to disclose. PubMed and EMBASE databases were searched to identify relevant studies published between January 2000 and April 2014. Rates of HIV serostatus disclosure to any person ranged from 5.0% to 96.7% (pooled estimate: 67.0%, 95% CI: 55.7%-78.3%). Women who chose to disclose their status did so more often to their partners (pooled estimate: 63.9%; 95% CI: 56.7%-71.1%) than to family members (pooled estimate: 40.1; 95% CI: 26.2%-54.0%), friends (pooled estimate: 6.4%; 95% CI: 3.0%-9.8%), or religious leaders (pooled estimate: 7.1%; 95% CI: 4.3%-9.8%). Most women disclosed prior to delivery. Decisions to disclose were associated with factors related to the woman herself (younger age, first pregnancies, knowing someone with HIV, lower levels of internalized stigma, and lower levels of avoidant coping), the partner (prior history of HIV testing and higher levels of educational attainment), their partnership (no history of domestic violence and financial independence), and the household (higher quality of housing and residing without co-spouses or extended family members). Interventions to encourage and support women in safely disclosing their status are needed.
