Two contiguous villages in Tracunhaém county (State of Pernambuco), endemic for schistosomiasis, were studied: Itapinassu (138 inhabitants) and São Joaquim (91 inhabitants). Agriculture predominates in the former region while ceramics is the main activity in the latter. Although no statistical difference was found regarding prevalence, severe infection (> 400 epg) predominated in Itapinassu, probably related to the kind of occupation. No association was found between parasite burden and severity of disease, in spite of the high infection rates for Schistosoma mansoni in both communities (approx. 60%). Typical epidemiological features of schistosomiasis such as age-related prevalences and intensities of infection (high in children, low in adults) were also mutual characteristics. Nutritional status determined through anthropometric evaluation was carried out by measuring specific anthropometric indicators. A deficit of energy intake, as well as vitamin A and riboflavin deficiencies were detected. The prevalence of moderate or severe undernutrition in patients under 18 years old was 21.9% in Itapinassu and 24.1% in São Joaquim. In this group an association was found between prevalence of schistosomiasis and chronic undernutrition. Similarly, for patients over 18 year old the prevalence of undernutrition was higher than 20%. However, in this case no association between nutritional status and either prevalence of schistosomiasis or parasite burden could be detected. The two communities had not been treated for eight years.
伊塔皮纳苏（138名居民）和圣若阿金（91名居民）。前一个地区以农业为主，而后一个地区的主要活动是制陶。尽管在患病率方面未发现统计学差异，但伊塔皮纳苏严重感染（>400 epg）占主导，这可能与职业类型有关。尽管两个社区曼氏血吸虫感染率都很高（约60%），但未发现寄生虫负荷与疾病严重程度之间存在关联。血吸虫病的典型流行病学特征，如与年龄相关的感染患病率和强度（儿童高，成人低）也是共同特征。通过测量特定人体测量指标对营养状况进行人体测量评估。检测到能量摄入不足以及维生素A和核黄素缺乏。18岁以下患者中，伊塔皮纳苏中度或重度营养不良的患病率为21.9%，圣若阿金为24.1%。在这一组中，发现血吸虫病患病率与慢性营养不良之间存在关联。同样，18岁以上患者的营养不良患病率高于20%。然而，在这种情况下，未检测到营养状况与血吸虫病患病率或寄生虫负荷之间存在关联。这两个社区已有八年未接受治疗。
