To analyze the contributions of the socioeconomic, hygienic, and sanitation improvements in reducing the prevalence of diarrhea in a city of the Amazon. In this population-based cross-sectional study, we analyzed data from surveys conducted in the city of Jordão, Acre. In 2005 and 2012, these surveys evaluated, respectively, 466 and 826 children under five years old. Questionnaires were applied on the socioeconomic conditions, construction of houses, food and hygienic habits, and environmental sanitation. We applied Pearson's Chi-squared test and Poisson regression to verify the relationship between origin of water, construction of homes, age of introduction of cow's milk in the diet, place of birth and the prevalence of diarrhea. The prevalence of diarrhea was reduced from 45.1% to 35.4%. We identified higher probability of diarrhea in children who did not use water from the public network, in those receiving cow's milk in the first month after birth, and in those living in houses made of paxiúba. Children born at home presented lower risk of diarrhea when compared to those who were born in hospital, with this difference reversing for the 2012 survey. Sanitation conditions improved with the increase of bathrooms with toilets, implementation of the Programa de Saúde da Família (PSF - Family Health Program), and water treatment in the city. The multivariate regression model identified a statistically significant association between use of water from the public network, construction of houses, late introduction of cow's milk, and access to health service with occurrence of diarrhea.

Neste estudo transversal de base populacional, foram analisados dados dos inquéritos realizados no município de Jordão, Acre. Em 2005 e 2012, foram avaliadas, respectivamente, 466 e 826 crianças menores de cinco anos. Foram aplicados questionários sobre as condições socioeconômicas, construção dos domicílios, hábitos higiênicos e alimentares e saneamento ambiental. Foi aplicado o teste Qui-quadrado de Pearson e a Regressão de Poisson para verificar a relação existente entre procedência da água, tipo de construção do domicílio, idade de introdução de leite de vaca na dieta e local de nascimento e a prevalência de diarreia. A prevalência de diarreia foi reduzida de 45,1% para 35,4%. Foi identificada maior probabilidade de desenvolvimen
