Abstract

A double-blind, placebo-controlled trial of nine months duration was carried out to investigate the impact of malaria and its prevention on the educational attainment of school children in a malaria-endemic area in southern Sri Lanka where both Plasmodium falciparum and P. vivax infections are prevalent. A total of 587 children attending grades 1-5 in four schools and resident in the area were randomly allocated to chloroquine (n = 295) and placebo (n = 292) arms. Language and mathematics scores of end-of-term school examinations for 1998 and 1999 and number of days absent and reasons for absenteeism during seven months pre-intervention and nine months of the intervention were recorded. The results indicate that there were no differences in language (95% confidence interval [CI] = 48.44-53.78 in chloroquine group and 50.43-55.81 in placebo group) and mathematics (95% CI = 49.24-54.38 in chloroquine group and 51.12-56.38 in placebo group) scores between the two groups prior to the intervention. During the intervention, the malaria incidence rate decreased by 55% (95% CI = 49-61%) and school absenteeism due to malaria was reduced by 62.5% (95% CI = 57-68%) in children who received chloroquine compared with the placebo group.
