Objectives: To determine if maternal education and wealth status predicts maternal self-reported unknown HIV status among women in Kenya. Methods: Kenya Demographic Health Survey (KDHS) 2008 – 2009 was used to examine the association between unknown HIV status and education and wealth, controlling for age, place of residence, place of delivery, history of intimate violence, knowledge of prevention of mother to child transmission (PMTCT), and health decision-making. Results: 617 (21.8%) had unknown HIV status. Education was not associated with unknown HIV status. Only women in the richest wealth category reported less unknown HIV status. Home and private facility births, high PMTCT knowledge and antenatal care (ANC) visits significantly decreased likelihood of unknown HIV status in education and wealth status model. Rural residence significantly predicted unknown HIV status in education model. Conclusion: There is a need to improve PMTCT knowledge and services in rural areas, and to maximize counseling and testing through antenatal care visits.
