Abstract

INTRODUCTION: Factors associated with precarious living and environmental conditions are frequently cited as major obstacles for the control of cholera outbreaks and epidemics. The purposes of the study are to evaluate the contribution of factors associated with the population living conditions and correlate the environmental problems with the onset of cholera and its subsequent impact. METHODS: Using a multiple linear regression by the backward stepwise method, and with the researcher's interaction, the study correlated socioeconomic indicators with cholera incidence rates in some counties of Pernambuco State, Brazil, during the year of 1992. RESULTS/CONCLUSIONS: The results of the adjusted model showed that the proportion of households without tap water was the variable that contributed the most to the increasing fluctuation of cholera incidence rates. Two other factors, the proportion of households without sewage and the proportion of householders with an income less than or equal to the minimum wage, also revealed a positive association with cholera incidence rates with statistically significant regression coefficients. The proportion of households with no sanitary installations whatsoever showed a negative association with cholera incidence rates, suggesting that sewage disposal, such as open-air sewage ditches, that is not part of the public sewage disposal system, increases the risk of environmental contamination The results indicate that having an adequate tap water supply is of maximum priority for cholera prevention.

INTRODUÇÃO: Fatores relacionados às condições de vida da população e condições ambientais precárias são freqüentemente citados como os maiores obstáculos para o controle de surtos e epidemias por cólera. Nesse sentido, realizou-se estudo com o objetivo de avaliar o peso de fatores referentes às condições de vida da população, relacionando questões ambientais com a instalação e o impacto da cólera. MÉTODO: Através de uma regressão linear múltipla, pelo método "backward stepwise", com influência do investigador, foram correlacionados os indicadores socioeconômicos com as taxas de incidência por cólera observadas nos municípios do Estado de Pernambuco, no ano de 1992. RESULTADOS/CONCLUSÕES: O modelo ajustado indica que a proporção de domicílios que utilizam água não proveniente de uma rede geral é a variável que tem maior peso na flutuação positiva das taxas de incidência de cólera. As variáveis "proporção de domicílios não ligados à rede geral de esgotos" e "proporção de chefes de família com renda igual ou menor do que um salário-mínimo mensal" também se associam positivamente, com coeficientes de regressão estatisticamente significativos, às taxas de incidência de cólera. A proporção de domicílios sem nenhuma instalação sanitária, por outro lado, se associa negativamente às taxas de incidência de cólera, sugerindo que instalações sanitárias, sem existência de rede de esgoto, aumentam o risco de contaminação ambiental. Os resultados apontam que a maior prioridade em saneamento é a oferta de água de boa qualidade.
