Breastfeeding cessation in the era of Elimination of Mother to Child Transmission of HIV in Uganda:

Abstract

Background: Among human immunodeficiency (HIV) infected mothers, the World Health Organization (WHO) recommends cessation of breastfeeding at one year to prevent HIV transmission but data are limited. We examined the frequency and factors associated with cessation of breastfeeding at one year among HIV infected postpartum mothers at Ndejje Health Center IV, a large Peri-urban health facility in Uganda.

Methods: This retrospective cohort study involved all HIV infected postpartum mothers enrolled in HIV care for at least 12 months between June 2014 and June 2018. We abstracted data from registers, held focused group discussions with HIV infected postpartum mothers, and key informant interviews with healthcare providers. Cessation of breastfeeding was defined as the proportion of HIV infected postpartum mothers who had stopped breastfeeding at one year. We summarized quantitative data descriptively, tested differences in outcome with the Chi-square and t-tests, and established independently associated factors using the modified Poisson regression analysis at 5% statistical significance level. We 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 HIV exposed infant (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 partner reminders about breastfeeding adequacy of BF knowledge and maternal literacy facilitated continued breastfeeding until one year. Inadequate breastfeeding knowledge, casual and formal work demands, in addition to increased breastfeeding demand among boys led to cessation of breastfeeding before one year.

Conclusion. Cessation of breastfeeding at one year among HIV infected postpartum mothers was sub optimal and this might increase risk of mother to child transmissions of HIV. Cessation of breastfeeding was more likely among female HEIs and multifarious mothers, and less likely when breastfeeding is initiated on same-day as birth. Interventions to enhance cessation of breastfeeding at one year should target groups of women with lower rates.
