Abstract
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.
