Socio-demographic associations of HIV among antenatal care attendees in selected rural primary care facilities in South Africa's Eastern Cape province
Abstract Background To effectively reduce vertical HIV transmission requires a reduction of HIV prevalence and incidence among pregnant women and a full understanding of its epidemiology. There is, however, literature paucity of HIV studies focusing on women attending antenatal care in rural areas in South Africa. Methods A Cross-sectional study of women attending antenatal care in four Primary Care facilities was conducted using an interviewer-administered questionnaire which collected information on socio-demographic characteristics and medical history. Binomial logistic regression analyses were used to determine factors associated with HIV and to estimate the prevalence ratio (PR). The 95% confidence interval (95%CI) is used for precision of estimates; p ≤ 0.05 for statistical significance. Results A total of 343 participants were recruited. The antenatal HIV prevalence was 38.2% (95%CI: 33.2–43.9). Participants older than 40 years were 4.6 times significantly more likely to be HIV positive compared to teenagers (p-value = 0.019). Furthermore, multiparous, unemployed and employed participants, were significantly associated with 40%, 60% and 70% higher antenatal HIV prevalences respectively when compared to primigravidas or tertiary students (p-value < 0.0001). Conclusion Despite a 100% antenatal HIV testing rate, the antenatal HIV prevalence remains high and is increasing in this population, coupled with no spousal attendance in antenatal care and poor condom compliance. It is therefore important to remain vigilant and monitor mother-to-child transmission that could be associated with this increased prevalence.
