Breastfeeding Among Women Living With HIV in the Era of Lifelong ART: An Observational Multicountry Study in Eastern and Southern Africa.

ABSTRACT:

Background

Lifelong antiretroviral treatment (ART) use is recommended for pregnant and breastfeeding (BF) women living with HIV (WLWH) to prevent perinatal HIV transmission and improve maternal health. We address 2 objectives in this analysis: (1) determine timing and factors associated with BF cessation and (2) assess the impact of BF on health of WLWH on ART.

Setting

This multicountry study included 8 sites in Uganda, Malawi, Zimbabwe, and South Africa.

Methods

This was a prospective study of WLWH on lifelong ART. These women initially participated from 2011 to 2016 in a randomized clinical trial (PROMISE) to prevent perinatal HIV transmission and subsequently reenrolled in an observational study (PROMOTE, 2016-2021) to assess ART adherence, safety, and impact.

Results

The PROMOTE cohort included 1987 women on ART. Of them, 752 breastfed and were included in analyses of objective 1; all women were included in analyses of objective 2. The median time to BF cessation varied by country (11.2-19.7 months). Country of residence, age, and health status of women were significantly associated with time to BF cessation (compared with Zimbabwe: Malawi, adjusted hazard ratio [aHR] 0.50, 95% confidence interval [95% CI]: 0.40 to 0.62, P < 0.001; South Africa, aHR 1.49, 95% CI: 1.11 to 2.00, P = 0.008; and Uganda, aHR 1.77, 95% CI: 1.37 to 2.29, P < 0.001). Women who breastfed had lower risk of being "unwell" compared with women who never breastfed (adjusted rate ratio 0.87, 95% CI: 0.81 to 0.95 P = 0.030).

Conclusion

Women on lifelong ART should be encouraged to continue BF with no concern for their health. Time to BF cessation should be monitored for proper counseling in each country.
