Changes in body mass index and hemoglobin concentration in breastfeeding women living with HIV with a CD4 count over 350: Results from 4 African countries (The ANRS 12174 trial)

Longitudinal interrelationship between HIV viral suppression, maternal weight change, breastfeeding, and length in HIV-exposed and uninfected infants participating in the Kabeho study in Kigali, Rwanda

PURPOSE

The health of infants that are HIV-exposed and -uninfected (HEU) is a major public health concern as HIV becomes a chronic condition. We investigate the interrelationship between maternal viral suppression, maternal weight status, breastfeeding, and infants that are HEU.

METHODS

The Kabeho study followed 502 HEU infants in Kigali, Rwanda, for 24 months from 2013 to 2014. We use a structural equation modeling approach to investigate the dynamic relationships between viral suppression, maternal weight change, breastfeeding, and infant length-for-age z-score (LAZ) as defined by the WHO.

RESULTS

Older mothers are more likely to be virally suppressed and to breastfeed. Viral suppression and the mother being on antiretroviral treatment for longer were related to lower infant LAZ at three months. A more positive maternal weight change was related to higher infant LAZ at the end of each period. At 12 months, a higher infant LAZ was related to increased probability of continued breastfeeding. At 18 months, continued breastfeeding was related to lower LAZ, and food shortages were related to higher LAZ.

CONCLUSION

There is a complex interrelationship between viral suppression, maternal weight change, breastfeeding, and infant LAZ. These relationships demonstrate the link between maternal and infant health in the context of HIV.
