Male partner involvement and successful completion of the prevention of mother-to-child transmission continuum of care in Kenya

Objective: To examine the relationship between male partner involvement (MPI) in prevention of mother-to-child transmission (PMTCT) activities and successful completion of the PMTCT continuum of care, which remains sub-optimal in settings with high prevalence of HIV. Methods: A cross-sectional survey was administered in June–August 2017 to a sample of 200 postpartum Kenyan women with HIV enrolled in a parent trial. Composite PMTCT and MPI variables were created. Descriptive, simple and multivariable regression, and mediation analyses were performed. Results: Of the women, 54% reported successful completion of PMTCT. Depression and internalized HIV stigma were independently associated with lower likelihood of successful completion of PMTCT (adjusted risk ratio [aRR] 0.97; 95% confidence interval [CI] 0.94–0.99; aRR 0.92; 95% CI 0.88–0.98, respectively). Each MPI activity was associated with 10% greater likelihood of successful completion of PMTCT (P < 0.05). The relationship between MPI and the successful completion of PMTCT was partially mediated through women's reduced internalized HIV stigma (β −0.03; 95%CI −0.06 to −0.00). Conclusion: Greater MPI in PMTCT activities has direct and indirect effects on women's successful completion of all necessary steps across the PMTCT continuum. Reduced internalized HIV stigma is likely a key mechanism in the relationship.
