To compare health and growth outcomes in children infected with HIV, children exposed to but uninfected with HIV, and children unexposed to HIV.Study designOur cohort included 3554 Tanzanian children enrolled in 2 trials of micronutrient supplementation. Among infants born to mothers infected with HIV, 264 were infected with HIV and 2088 were exposed to but uninfected at 6 weeks of age. An additional 1202 infants were unexposed to HIV. Infants were followed until 18 months of age, death, or loss to follow-up. Morbidity and growth were assessed at monthly nurse visits.ResultsCompared with unexposed infants, hazard ratios (95% CI) for all-cause mortality in infants infected with HIV and infants who were exposed to but uninfected with HIV were 28.99 (14.83-56.66) and 2.79 (1.41-5.53), respectively, after adjusting for demographic and nutritional covariates. Compared with infants unexposed to HIV, infants infected with HIV also had a significantly greater risk of all measured morbidities, while infants who were exposed to but uninfected with HIV were significantly more likely to suffer from cough, fever, unscheduled outpatient visits, and hospitalizations. Infants infected with HIV also were more likely to experience stunting, wasting, and underweight at baseline and during follow-up. Infants exposed to but uninfected with HIV were more likely to be underweight at baseline (adjusted relative risk, 2.05; 95% CI, 1.45-2.89), but on average, experienced slower declines in height-for-age z-score, weight-for-age z-score, and weight-for-height z-score as well as a lower rate of stunting over follow-up, compared with unexposed infants.ConclusionIn addition to preventing and treating HIV infection in infants, prevention-of-mother-to-child-transmission of HIV and child health services should also target children exposed to but uninfected with HIV to improve health outcomes in this vulnerable population.Trial registrationClinicaltrials.gov: NCT00197730 and NCT00421668.
