Resumo: | OBJECTIVE: Data from two consecutive household surveys undertaken in mid-80s and mid-90s allow to characterize and analyse secular trends in infant and child diarrhea in the city of S. Paulo, Brazil. METHODS: The two surveys included random population samples aged from zero to 59 months of age (1,016 in the period of 1984-85 and 1,280 in 1995-96). In both surveys the instant prevalence of diarrhea (proportion of examined individuals reporting three or more episodes of liquid stools in 24 hours) and the annual incidence of hospitalizations due to the disease were calculated. These two indicators were estimated from household interviews conducted by pediatricians with the children's mothers. In both surveys the interviews were distributed throughout a period of almost 12 months to assure a uniform coverage of the various areas of the city during the four seasons. For each survey, the study of the social distribution of the disease took into account tertiles of the per capita family income. For the study of the determinants of secular trends, hierarchical causal models, multivariate regression analyses and calculations analogous to the ones used to assess population attributable risks were applied. RESULTS/CONCLUSIONS: In the time span from the first to the second survey, there was substantial reduction in both the prevalence of diarrhea (from 1.70% to 0.90%) and the hospitalizations due to the disease (from 2.21 to 0.79 hospitalizations per 100 children-year). A more significant reduction was observed among the third poorest families, narrowing the social gradient relative to the disease. An increase in family income and improvement in water supply could substantially explain part of the decline in the disease and, for children under two years of age, a discrete increase in breast-feeding may have also played a positive role. |

OBJETIVO: Estimar a prevalência e a distribuição social da doença diarréica na infância, estabelecer a tendência secular dessa enfermidade e analisar sua determinação, através dos dados coletados por dois inquéritos domiciliares realizados na cidade de São Paulo, SP, em 1984/85 e 1995/96. MÉTODOS: Os inquéritos estudaram amostras probabilísticas da população residente na cidade com idades entre zero e 59 meses (1.016 em 1984/85 e 1.280 em 1995/96). Nos dois inquéritos foram estimadas a prevalência instantânea da diarréia (proporção de crianças com três ou mais evacuações líquidas no dia da entrevista domiciliar) e a incidência anual de internações hospitalares pela doença. Esses dois indicadores foram calculados a partir de entrevistas domiciliares feitas por médicos pediatras e respondidas pelas mães das crianças. Nos dois inquéritos, as entrevistas foram distribuídas ao longo de um período de cerca de 12 meses, de modo a garantir uma varredura uniforme das várias áreas da cidade ao longo das quatro estações do ano. O estudo da distribuição social da doença diarréica levou em conta tercis da renda familiar per capita em cada um dos inquéritos. A estratégia analítica para estudar os determinantes da evolução da prevalência da doença na população empregou modelos hierárquicos de causalidade, análises multivariadas de regressão e procedimentos análogos aos utilizados para calcular riscos atribuíveis populacionais. RESULTADOS/CONCLUSÕES: Houve entre os inquéritos reduções expressivas na prevalência instantânea da diarréia (de 1,70% para 0,90%) e na incidência anual de hospitalizações pela doença (de 2,21 para 0,79 internações por 100 crianças-ano). O declínio desses indicadores foi mais intenso no terço mais pobre da população, o que contribuiu para reduzir a desigualdade social quanto à ocorrência da doença. Melhorias no poder aquisitivo das famílias e na cobertura da rede pública de abastecimento de água justificariam parte considerável do declínio na prevalência da diarréia, havendo ainda indicação de que, entre crianças menores de dois anos, esse declínio possa ter sido favorecido por um aumento discreto na freqüência da amamentação.
