Weight loss is a major complication in children infected with HIV. Very few studies have focused on the nutritional management of malnourished HIV-positive children, particularly in developing countries, although there have been some studies in adults. Therefore, the aim of this retrospective study was to evaluate, as a function of HIV status, the effect of a nutritional rehabilitation program on the mortality of malnourished children in an Ivory Coast nursery. We studied 193 malnourished children over the age of 15 months from January 1 1994 to December 31 1996; 41 % of these children (80 of 193) were HIV-positive. The nutritional rehabilitation program was introduced in 1995. It had a beneficial effect in HIV-negative children because the setback rate (the number of deaths and transfers x 1,000/the number of child-months at risk) decreased significantly over the three years of the study (1994: 130; 1995: 113; 1996: 26; p < 0.05). The rate in HIV-positive children did fall slightly, but this decrease was not statistically significant. These results demonstrate the difficulties involved in the nutritional management of malnourished HIV-positive children. However, recent studies have suggested that nutritional rehabilitation (by mouth) combined with total vitamin and mineral supplementation may be more effective. Given the frequency of malnutrition in HIV-positive children, clinical studies aimed at improving the nutritional management of these children should be a priority in developing countries.
