Objective: To compare the anthropometric characteristics of children with and without HIV-1 infection.
Methods: In a prospective cohort study of 218 children born to HIV-1 seropositive mothers and 218 children born to HIV-1 seronegative mothers in Kigali, Rwanda, 3 groups were compared: infected children (n = 46); uninfected children born to seropositive mothers (n = 140); and uninfected children born to seronegative mothers (n = 207). Weight, height and head circumference were measured at birth, every 3 months during the first year of life and every 6 months thereafter. The weight-for-age, height-for-age, weight-for-height and head circumference-for-age mean z scores were calculated.
Results: The weight-for-age, height-for-age and head circumference-for-age mean z scores were lower among HIV-infected children than among uninfected ones at each time period. The reduction in the weight-for-age mean z score was the greatest between 12 and 36 months. The reduction in the height-for-age mean z score of HIV-infected children was persistently below 2 SD after 9 months of age. On the other hand the weight-for-height mean z score was not consistently lower in HIV-infected children when compared with uninfected ones. The anthropometric characteristics of uninfected children born to seropositive mothers were similar to those of children born to seronegative mothers.
Conclusions: In this study HIV-infected children were more frequently stunted (low height-for-age) than uninfected ones. Wasting (low weight-for-height) was not common among HIV-infected children.
