Abstract: A longitudinal double blinds study was designed to investigate the impact of urinary schistosomiasis on the nutritional stats of school children, in Rahad area of Northern Kordofan. The children were allocated at random to either praziquantl treatment or placebo and followed for one year. The effect of the infection and resulted pathology, enviromental and demographic factors, the dietary practiece and socio-economic conditions on the nutritional status of 800 children was studies crosssectionally. Anthropometry and iron status were the indicators to nutritional status in the study. The effect of praziquantel treatment on the nutritional status was assessed after 6 and 12 months. The data revealed a prevalence rate of 24.4 percent among 3880 boys and girls screened for urianry schistsomiasis in the town and villages surrounding the lagoon TURADA. The study revealed statistically significant differences in intensity of infection when analysed against sex, ethnic group and frequency of visits to TURDA. The intensity was greater among boys (t-value equal 245, p equal0.015), non-arabs (t-value equal 2.35 and p equal 0.009) and in those who visited the Turda grater than 4 times a week (t-value equal 2.35 and p equal 0.017) than girls, arabs or those who less frequently visited Turda. Alternatively, no significant differences were found with age, rural or urban residence, parents literacy, house-latrine availability or closeness of home to Turda. The assessment of nutritional status revealed that 6 children (0.9 percent) were severely wasted i.e. very thin, mildly wasted were 70 cases (10.9 percent), while severely stunted children i.e. very short, were 8 (1 percent) and mildly stunted were 69 (8.9 percent). Severe under nutrition was indicated in 3 cases (0.4 percent) and mildly under nourished were 100 cases (12.8 percent). When these indicators were interpreted together, according to the criteria set by the WHO, it was found that 4 cases were perviously underfed and were still so when examined. Another 96 cases (15 percent) were normally fed in the past, but currently improved.
