Background:
HIV/AIDS is a major public health concern globally. In Africa 25.7 million people are infected with HIV. HIV Preva- lence rate among pregnant women in Namibia is 17.2%. Zambezi region has the highest (32.9%) HIV/AIDS preva- lence in Namibia. The aim of study was to determine the prevalence and trend of HIV among pregnant women in Katima Mulilo maternity ward, from 2013 to 2017.
Methods:
We conducted a cross-sectional study and reviewed delivery registers in the maternity ward from 2013-2017. We defined a case as any HIV positive pregnant women who presented at Katima Mulilo maternity ward for delivery between 2013- 2017. Variables reviewed included age, physical address, parity, HIV and Antiretroviral Therapy (ART) status. Data was analyzed using Epi info 7 software. We calculated frequencies and proportions of deliveries among HIV positive pregnant women. Statistical significance was determined at P-value <0.05.
Results:
There were 11647 total deliveries recorded between 2013 -2017 in Katima Mulilo maternity ward. At the time of delivery 3590 (30.8%) were HIV positive. HIV positive cases increased over the years: 336 (9.7%) in 2013, 759 (21%) in 2014, 700 (18.6%) in 2015, 915 (24%) in 2016, and 1064 (26 %) in 2017, with a p-value=0.001. Women 20-29 years of age had the highest 3451(45%) HIV prevalence compared to other age groups (p-value=0.001). Overall, HIV prevalence was highest in multi-gravida 3070 (82%) compared to primi-gravida 695 (18%). Most HIV cases came from Chotto 501(13%) and Cowboy residential areas 301(8%). A total of 3078 (86.2%) HIV positive mothers were on ART for >4 weeks, 10 (0.3%) were on ART for <4 weeks, 345 (9.7%) were given a combination of Nevirapine, Zidovudine and Lamivudine at onset of labour, 130 (3.6%) were not on any ART at the time of delivery and 7 (0.2%) refused ART at the time of delivery.
Conclusion
HIV/AIDS remains a major public health problem in Namibia specifically in Zambezi region. HIV prevalence in- creased yearly among pregnant women who presented in Katima Mulilo maternity ward. We recommended age and location specific targeted interventions to reduce new infections among women.
