Rev Peru Med Exp Salud Publica [online]. 2010, vol.27, n.4, pp.506-511. ISSN 1726-4634. http://dx.doi.org/10.1590/S1726-46342010000400003.
Objective. To evaluate the proportion of children under five with access to quality water and its behavior according to geographical location, water supply and poverty status. Material and methods. Continuous survey (repeated cross), with multistage random sampling, being the universe children under five years living in Peru. We evaluated the presence of free chlorine in drinking water samples in the dwellings of 3570 children (Metropolitan Lima 666, Rest of Coast 755, Urban Sierra 703, Rural Sierra 667, and Jungle 779). We evaluated the presence of total coliforms and E. coli in water samples of 2310 households (445 Metropolitan Lima, Rest of Coast 510, Urban Sierra 479, Rural Sierra Selva 393 and 483). Results. The national proportion of children under five years living in households with adequate free chlorine in drinking water reaches 19.5% of the total, while water free of coliforms and E. coli is 38.3%. There is a marked difference in results by area of residence (the most affected areas were rural Sierra and Jungle), public network at home inside the dwelling and income quintiles. Conclusion. Children under five years living in households belonging to the rural areas and extreme poverty, have a great disadvantage to access quality water consumption. This situation represents a serious problem for the control of diarrheal diseases and children malnutrition.
