Background: We investigated 18-month incidence and determinants of death and loss to follow-up of children after antiretroviral therapy (ART) initiation in a multiregional collaboration in lower-income countries.

Methods: HIV-infected children (positive polymerase chain reaction <18 months or positive serology ≥18 months) from International Epidemiologic Databases to Evaluate AIDS cohorts, <16 years, initiating ART were eligible. A competing risk regression model was used to analyze the independent risk of 2 failure types: death and loss to follow-up (>6 months).
