This study was conducted among 1170 children aged 6 to 65 months in Faki Hashim and Gezira Slanj villages, Sudan, to determine the impact of malaria and insecticide-impregnated bednets on anthropometry and growth. Impregnated bednets were distributed to 581 of 611 F.Hashim children. From June 1997 through March 1998, children were followed up with quarterly anthropometric and blood film surveys, and fortnightly child health questionnaires. In the first survey at the end of June 1997, mean weight-for-age scores corresponded to 87.8% of the NCHS median for females and 85.7% for males. Weight, height and arm circumference appeared to be largely accounted for by age and sex (up to 73%, 86% and 21% of the variance respectively) and by socio-economic influences (0.4% to 3.5%). In contrast, much of the variation in Z scores could not be explained. Quarterly changes in weight averaged +0.4 to +0.7 kg, while mean height gains were between +1.7 and +2.4 cm in 3 months. During the 9 months follow-up, 55.1% of children in F.Hashim and 32.6% in G.Slanj experienced an episode of malaria. The distribution was seasonal with point prevalences ranging between 5.1% and 12.1% in F.Hashim and 0.8% to 3.8% in G.Slanj. Fevers were associated with smaller changes in weight, weight-for-age and arm circumference in the first interval, but only arm circumference in the second interval. Malaria was associated with smaller changes in weight-for-age in the first and second intervals, and with a higher risk of developing stunting over the 9 months, particularly during the third interval. Because the bednets had been introduced into a community without a tradition of using nets, mothers' compliance with using the impregnated bednets was poor. A comparative stub-study among 148 children not using bednets was conducted in the Atashab sector of F.Hashim from January to March 1998. Despite, some evidence of reduced malaria, the impregnated bednets could not be shown to influence anthropometry or growth in F.Hashim.
