OBJECTIVES: To identify potential predictors of mortality, to determine mortality rate and to identify prevalent causes of death in a cohort of HIV-1 exposed uninfected infants. DESIGN: Prospective cohort study. SETTING: Kenyatta National Hospital, Nairobi, Kenya. SUBJECTS: Three hundred and fifty one HIV-1 exposed uninfected post-neonatal infants who survived to one year of age. RESULTS: Sixteen infants died (post-neonatal mortality rate of 47/1000 live births), 14 (88%) before six months of age. The most frequently identified medical conditions at death included bronchopneumonia, diarrhoea and failure to thrive. In multivariate analysis, prematurity (RR=10.5, 95%CI 3.8-29.1, p<0.001), teenage motherhood (RR=3.6, Cl 1.0-13.2, p=0.05) and symptomatic maternal HIV-1 disease (RR=2.7, CI 0.9-7.7, p=0.06) were associated with infant mortality. CONCLUSION: Prematurity, teenage motherhood and symptomatic HIV-1 maternal disease were important predictors for post-neonatal mortality in this cohort of HIV-1 exposed uninfected infants. These factors should be considered in monitoring and follow up in prevention of mother-to-child HIV-1 transmission (PMTCT) programs.
