Abstract
Background and Objective: Retaining women in Option B+ services is crucial for eliminating new pediatric HIV infections. However, there are few studies on factors influencing retention at the district level. This study evaluates the factors associated with retention in two health districts of Cameroon.
Methods: From September 1, 2015, to February 29, 2016, we reviewed the records of pregnant and breastfeeding women initiating Option B+, a lifelong approach to preventing mother-to-child transmission (PMTCT) of HIV, between October 2013 and July 2014. We abstracted sociodemographic and clinical data from registers in 22 health facilities in the Bamenda urban and Kumba rural districts into spreadsheets. Cox regression age-adjusted survival curves were used to compare retention probabilities at 6 and 12 months post-antiretroviral therapy (ART) initiation. Multivariable modified Poisson regressions were run to estimate adjusted relative risk (aRR) of factors associated with retention in PMTCT care at 12 months post-ART initiation. STATA software was used for the analyses.
Results: Of the 560 files reviewed, majority, 62.7% (n=351), were above 24 years of age and married, 68.9% (n=386). From the multivariable analysis, enrolling early in antenatal care (ANC) (aRR: 1.50, 95% CI: 1.17- 1.93) and knowing the male partner’s HIV-negative status (aRR: 1.16, 95% CI: 1.00-1.34) were significantly associated with higher retention in care, adjusting for maternal age, marital status, and distance from the health facility. By health district, knowing the male partner’s HIV-negative status (aRR: 1.30, 95% CI: 1.13-1.50) in the Bamenda urban and enrolling early in ANC (aRR: 2.03, 95% CI: 1.21-3.41) in the Kumba rural district, had significantly higher retention rates after adjusting for the same covariates.
Conclusion and Global Health Implications: Overall, factors influencing retention varied by urban or rural district. Therefore, tailored district-level interventions are needed to enhance early ANC enrollment in the rural and partner HIV status disclosure in the urban districts to improve retention in PMTCT care.
