Title: Factors involved in Schistosoma mansoni infection, in rural areas of northeast Brazil
Issue Date: 31-Dec-1997

Abstract: Mem Inst Oswaldo Cruz, Rio de Janeiro, Vol. 92(5), September/October 1997, pp. 707-715 Factors involved in Schistosoma mansoni infection, in rural areas of northeast Brazil Eridan M Coutinho, Frederico GC Abath, Constanca S Barbosa, Ana Lucia C Domingues, Marcelo CV Melo, Silvia ML Montenegro, Maria Anunciada F Lucena, Sylvia AM Romani, Wayner V Souza, Amaury D Coutinho; Code Number:OC97132 Sizes of Files: Text: 36.1K Graphics: Tables (jpg) - 264.3K Line drawings (jpg) - 22.9K Two contiguous villages in Tracunhaem county (State of Pernambuco), endemic for schistosomiasis, were studied: Itapinassu (138 inhabitants) and Sao 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 Sao 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. Key words: epidemiology - schistosomiasis - risk factors - nutrition Copyright 1997 Fundacao Oswaldo Cruz
