Estudo da associação entre fatores socioambientais e prevalência de parasitose intestinal em área periférica da cidade de Manaus (AM, Brasil)

Abstract

This study assesses the association between socio-environmental factors and urban sanitation conditions with the prevalence of intestinal parasitosis in a community on the periphery of the city of Manaus. The study comprised a socio- environmental survey and a parasitological inquiry. A heterogeneous community was revealed with some socio-economic and environmental differences between the micro-areas evaluated, even though the urban sanitation conditions were found to be predominantly precarious. The prevalance of intestinal parasitosis was 44.2%. There was no significant difference between the microareas that could explain the occurrence of intestinal parasitosis. An association was found between intestinal parasitosis and residential building types, age bracket and the quality of the water used for personal hygiene and consumption in the home. Open air sewerage was a risk factor associated with intestinal parasitosis (OR=6.72; p=0.034) and also with intestinal protozoa (OR=21.87; p=0.004). In terms of the presence of protozoa, two risk factors were verified: the dumping of sewage directly into the river system (OR=12.98; p=0.011) and the use of rudimentary cesspits (OR=9.54; p=0.019).
