    Abstract:
    BACKGROUND: The risk of HIV-1 infection is high among breast-fed children in sub-Saharan Africa. Monitoring the nutritional status can provide useful information to determine the effect of HIV infection and breast-feeding on child growth and development. We longitudinally assessed the nutritional status and determined its association with HIV infection and breast-feeding among Malawian children. METHODS: We analyzed data from 2 clinical trials to prevent mother-to-child transmission of HIV in Malawi. These trials were conducted during 2000-2003 before the current guidelines were implemented to breast-feed exclusively during the first 6 months and wean thereafter. The nutritional status of children was measured up to age 24 months, using z-scores. Age-specific differences in length-for-age (L/A), weight-for-age (W/A), and weight-for-length (W/L) were compared stratifying by gender and HIV infection status. Multivariable models examined the mean change in z-scores controlling for breast-feeding and other factors. RESULTS: In this analysis, 1589 children were included. Boys had significantly lower L/A scores and became stunted (z-score -<2 standard deviations) earlier than girls. HIV-infected children had significantly lower mean L/A and W/A z-scores than HIV-uninfected children and became stunted and underweight at an earlier age. In multivariable analysis not being breast-fed and being HIV infected were significantly (P < 0.001) associated with decreases in mean L/A, W/A, and W/L z-scores. CONCLUSIONS: This study shows the impact of infant HIV infection on growth and supports the critical importance of breast-feeding. Mother-to-child transmission of HIV programs should endeavor to preserve breast-feeding and find alternative measures to prevent postnatal HIV transmission.
