Background
To eliminate mother to child transmission of HIV (EMTCT), the World Health Organization (WHO) recommends that breastfeeding should cease at one year for infants born to HIV infected mothers but data are limited. We examined the magnitude and factors associated with breastfeeding cessation at one year among HIV infected postpartum mothers at Ndejje Health Center IV, a large peri-urban health facility in Uganda.
Methods
We conducted a retrospective cohort study involving all HIV infected postpartum mothers enrolled on EMTCT program for at least 12 months, between June 2014 and June 2018, abstracted data from EMTCT registers, held four focused group discussions with HIV infected postpartum mothers and four key informant interviews with healthcare providers. Breastfeeding cessation was defined as the proportion of HIV infected postpartum mothers who stopped breastfeeding an HIV exposed infant (HEI) at one year. We summarized quantitative data descriptively, tested differences in outcome with the Chi-square and t-tests, and established factors independently associated with breastfeeding cessation using modified Poisson regression analysis at 5% statistical significance level, and thematically analyzed qualitative data to enrich and triangulate the quantitative results.
Results
Of 235 HIV infected postpartum mothers, 150 (63.8%) ceased breastfeeding at one year and this was independently associated with the HEI being female than male (Adjusted risk ratio (aRR): 1.25, 95% confidence interval (CI), 1.04, 1.50), the mother being multiparous than primparous (aRR, 1.26; 95% CI, 1.04-1.53), and breastfeeding initiation on same day as birth (aRR, 0.06; 95% CI, 0.01-0.41). Qualitative results showed that maternal demands of work, high demand for breastfeeding among male HEIs, and low breastfeeding interest among primarous mothers were reasons for cessation of breastfeeding before one year.
Conclusion
Breastfeeding cessation at one year among HIV infected postpartum mothers was suboptimal. This might increase the risk of mother to child transmissions of HIV. Breastfeeding cessation at one year was more likely when the HEI was female than male and when the HIV infected postpartum mother was multiparous than primparous, but less likely when breastfeeding was initiated on same-day as birth. Interventions to enhance breastfeeding cessation at one year should target these areas.
