Modeling Health Systems and Male-Partner Involvement Determinants of Prevention of Mother to Child Transmission of Human Immune-deficiency Virus among Women in Homa Bay County Referral Hospital, Kenya

Abstract

In 2017, Homa Bay County accounted for 10% of HIV cases among children aged 0-14 years in Kenya. Additionally, it reported 8.8% of new HIV infections among children of the same age group and 9.7% of annual AIDS-related mortalities. In 2018, the County reported a mother-to-child transmission (MTCT) rate of 8.1%, higher than the 5% target set by WHO. Limited studies in Kenya have documented health systems and male-partner involvement determinants of prevention of MTCT (PMTCT) of HIV, which vary by context. Thus, this paper documents health systems and male-partner involvement determinants of PMTCT outcomes among women attending Homa Bay County Referral Hospital. We used an analytical cross-sectional study design that had a sample of 274 (Fishers et al. 1998) randomly selected from 4129 women of reproductive age ever on PMTCT follow-up. Questionnaires were used to collect data from the women on child HIV status, health systems factors, and male partner-involvement factors. The mean age of the women was 32.16 years. Results show that provision and discussion of infant diagnosis results by health care providers increased the chances of occurrence of HIV seronegative PMTCT outcome by 1.5 times (OR=1.530, 95% CI: 0.361-6.486; p<0.0001). Provision of routine pre-conception counselling decreased the odds of determining PMTCT outcome by 60% (OR=0.404, 95% CI: 0.046-3.521; p=0.018). Males knowing the HIV status of their partner had higher odds of determining the occurrence of HIV seronegative PMTCT outcome (OR=6.0, 95% CI: 0.655-54.997; p<0.0001). Health systems factors aligned with the provision and discussion of infant diagnosis results by healthcare provider and male-partner involvement factor related to the male partner knowing the HIV status of participant(s) demonstrated higher chances of predicting the occurrence of HIV seronegative for the child. These findings will inform the formulation of interventions geared towards reducing the high MTCT rates in Homa Bay County
