We present baseline cross-sectional data from a nested cohort study comparing indicators of morbidity for measuring program impact. Eight hundred twenty-two schoolchildren 7\u20138 years of age from Nyanza Province, Kenya, contributed stool for diagnosis of <jats:italic>Schistosoma mansoni<\/jats:italic> and soil-transmitted helminths (STH) and blood smears for malaria, and were evaluated for anemia, quality of life, exercise tolerance, anthropometry, and ultrasound abnormalities. <jats:italic>Schistosoma mansoni<\/jats:italic>, STH, and malaria infection prevalence were 69%, 25%, and 8%, respectively. Only anemia and <jats:italic>S. mansoni<\/jats:italic> infection (adjusted odds ratio [aOR] = 1.70; confidence interval [CI] = 1.03\u20132.80), and hepatomegaly and heavy <jats:italic>S. mansoni<\/jats:italic> infection (aOR = 2.21; CI = 1.19\u20134.11) were associated. Though anemia and hepatomegaly appeared most useful at baseline, additional morbidity indicators may be sensitive longitudinal measures to evaluate schistosomiasis program health impact.<\/jats:p>","DOI":"10.4269\/ajtmh.2012.12-0397","type":"journal-article","created":{"date-parts":[[2012,9,21]],"date-time":"2012-09-21T15:15:22Z","timestamp":1348240522000},"page":"874-882","source":"Crossref","is-referenced-by-count":37,"title":["Schistosoma mansoni Morbidity among School-Aged Children: A SCORE Project in Kenya"],"prefix":"10.4269","volume":"87","author":[{"given":"Aaron M.","family":"Samuels","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elizabeth","family":"Matey","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pauline N.
