Abstract Background HIV-exposed but uninfected (HEU) children are at increased risk for poorer growth outcomes compared with HIV-unexposed/uninfected (HUU) children. Mechanisms underlying the poorer growth and delays in development of HEU children compared HUU children are not fully understood. We sought to define the relationship between child CMV status and HIV− exposure status and determine if a correlation existed between CMV status and growth (and neurodevelopmental) outcomes by 24 months of age in Botswana. Methods We used existing data and samples from the observational Botswana Tshipidi study, pregnant women living with HIV (WLHIV) and those without HIV, as well as their infants were enrolled and followed prospectively through 2 years postpartum. We tested 18-month child plasma samples from all available children for anti-HCMV IgG. We evaluated the association between positive (vs. negative) child CMV status at 18 months, and child growth, using the World Health Organization’s Growth Standard adjusted for age and sex and neurodevelopment at 24 months of age, using the Bayley Scales of Child Development (BSID) III. Results Of 317 children tested for CMV IgG at 18 months, 215 (67.8%) tested positive. Significantly higher proportions of HUU children had positive CMV serology (82.6%) compared with HEU children (47.4%, P < 0.01); 96.7% of HUU vs. 10.5% of HEU children breastfed. Child CMV infection was not associated with head circumference, weight-for-age, weight-for-height, nor height-for-age z-scores at 24 months. BSID III scores in receptive and expressive language, fine and gross motor, and cognitive domains at 24 months of age also did not differ by child CMV status. Conclusion We observed high rates of CMV seropositivity in 18-month-old children in Botswana with significantly higher CMV seropositivity among HUU children likely owing to breastfeeding. Positive CMV serostatus was not associated with child growth or neurodevelopmental outcomes at 24 months. Disclosures All authors: No reported disclosures.
