ABSTRACT Objective There is a growing body of data that demonstrates increased infectious disease outcomes for HIV-exposed uninfected (HIV-EU) infants as compared to their HIV-unexposed (HU) counterparts. We hypothesized that these HIV-EU infants are at greater risk for infectious morbidity and mortality when compared to the general childhood population. We therefore aimed to characterize infections and growth outcomes among HIV-EU infants in Jamaica during their first two years of life. By identifying these outcomes, specific interventions could be implemented to mitigate this risk of morbidity and mortality. Methods HIV-EU infants born between 1 January 2004 and 31 December 2006 in Kingston, Jamaica, were enrolled and followed in multicenter health facilities, using standardized protocols. HIV status was determined by RNA/DNA polymerase chain reaction (PCR) and confirmatory HIV enzyme-linked immunoassay (ELISA). Data were collected on demographic and anthropometric characteristics, infectious morbidity and mortality, and hospitalizations. Outcomes (incidence of infections and hospitalizations; growth (z scores for weight)) were determined, using univariate analyses. Results Of 195 HIV-EU infants followed for 25.9 months (standard deviation, 10.9 months), 102 (52%) were male, 185 (95%) were non-breast-fed, 161 (83%) experienced at least one infection, and 58 (30%) were hospitalized at least once. Infectious disease incidence per 1 000 child-weeks included upper respiratory tract infection of 7.25 (95% confidence interval (CI): 5.92–8.90), otitis media of 4.12 (3.21–5.20), and acute gastroenteritis (AGE) of 1.92 (1.35–2.65). Hospitalization incidence per 1 000 child-weeks included lower respiratory tract infections (LRTIs) of 0.89 (0.53–1.40), sepsis of 0.48 (0.23–0.89), and AGE of 0.43 (0.20–0.81). These infection incidence rates among the HIV-EU infants were higher than those for published community controls. Among the HIV-EU infants, the low-birthweight ones and those born via cesarean section had ...
