Abstract

Advances have occurred in relation to the coverage of water supply and sanitation in Brazil, however inequalities are still observed in relation to the coverage of these services, reflecting the importance of diarrheal disease in the Brazilian epidemiological context. The aim of this study was to measure the impact of the water supply and sanitation system on diarrheal diseases among children aged under five. The global burden of diarrhea was calculated based on the attributable population fraction, using information on prevalence and relative risks from the 2000/2010 censuses and a study by Pruss et al. The north of the State of Minas Gerais, the Northeast and Jequitinhonha regions had the highest disability-adjusted life year (DALY) rates and ratios. The fraction of diarrhea attributable to the water supply and sanitation system was 83%, decreasing to 78.3% where sanitation had 100% coverage. An inverse relationship was found between DALY rates and attributable fractions and per capita GDP. Broadening the scope and coverage of services and improving the quality of water available in homes is an urgent requirement. These measures will bring economic and social benefits related to the reduction of diarrheal diseases and consequent improvement of the quality of life of children aged under five.
