BACKGROUND: The relationships among weight and height growth, viral load and survival in HIV-infected children remain unclear. OBJECTIVES: To determine whether weight or height growth velocity independently predicts survival and to investigate associations of weight, height and head circumference growth velocities with viral loads in symptomatic HIV-infected children. METHODS: We analyzed data from a prospective antiretroviral study utilizing clinical endpoints (PACTG 152). Viral load [log(RNA PCR)] and anthropometric measures 12 weeks before and after viral load measures were available in 494 of 831 children. Interval changes during 24 weeks in z-scores for weight-for-age (DeltaWAZ), height-for-age (DeltaHAZ) and head circumference-for-age (DeltaHCZ) were used as growth velocity surrogates. Logistic regression determined whether DeltaWAZ and/or DeltaHAZ correlated with survival when age, viral load and CD4+ cell count were controlled. Bivariate analysis assessed correlation among viral load and DeltaWAZ, DeltaHAZ and/or DeltaHCZ. RESULTS: Survival related significantly to height growth velocity (P = 0.03, n = 434) but not to weight growth velocity (P = 0.84, n = 446) or head circumference growth velocity (P = 0.67, n = 148). Viral load was not significantly associated with changes in weight-, height-, or head circumference-for-age z scores (P = 0.86, n = 235; P = 0.07, n = 226; and P = 0.09, n = 165, respectively) in children <30 months of age or with changes in weight- or height-for-age z scores (P = 0.27, n = 259; P = 0.11, n = 251) in older children. CONCLUSIONS: Height growth velocity predicted survival independently of age, viral load and CD4+ cell count. Weight, height and head circumference growth velocities were not significantly associated with viral load in symptomatic HIV-infected children in this large prospective trial of nucleoside reverse transcriptase therapy.
