The Impact of Water Supply and Sanitation on Child Health: Evidence from Egypt
نویسندگان
چکیده
Using a combination of qualitative and quantitative data, this paper investigates whether access to improved sources of water and sanitation is an effective ―treatment‖ for the incidence of diarrhea among children under five years of age in Egypt. The qualitative component of the paper draws on in-depth interviews and focus group discussions with residents of three governorates to present an account of Egypt’s drinking water and sanitation services. The quantitative analysis then uses 2008 Egypt Demographic and Health Survey data to investigate the insights obtained from the qualitative research conducted on a large nationally representative sample. Both the quantitative and qualitative components of the study indicate that widespread access to improved sources of drinking water and toilet facilities exists across Egypt; however, service quality remains a significant problem in many areas. In particular, cuts in water supply— and the resulting practice of storing water—are quite common. A sizable percentage of flush toilet facilities are not connected to the public sewer system, and evacuation and disposal services for septic tanks are inadequate. Quantitative analysis, using propensity score matching techniques, indicates that having an uninterrupted water supply has a significant negative effect on the incidence of childhood diarrhea. Nevertheless, having a flush toilet facility connected to the sewer system is found to have a positive effect on the incidence of childhood diarrhea, leading us to conclude that there are other important measures of service quality not captured by the survey data used.

The effect of water and sanitation on child mortality in Egypt
This paper assesses water and sanitation’s impacts on child mortality in Egypt. The analysis is conducted using a three-part model specification, comprising discrete choice to model the child prospects of dying during the neonatal period. The remaining parts uses transition models to model infant and childhood risk of death where unobserved heterogeneity is accounted for. The results show that ...
متن کاملImproved water and child health in Egypt: impact of interrupted water supply and storage of household water on the prevalence of diarrhoea.
Egypt is approaching universal access to improved water supply, but the variable quality of improved water may have a measureable health impact. We investigated the impact of different measures of improved water access on the prevalence of diarrhoea among children aged under 5 years. Using data from the 2008 Egypt Demographic and Health Survey and propensity score matching techniques we compare...

A total of 144 studies were analysed to examine the impact of improved water supply and sanitation facilities on ascariasis, diarrhoea, dracunculiasis, hookworm infection, schistosomiasis, and trachoma. These diseases were selected because they are widespread and illustrate the variety of mechanisms through which improved water and sanitation can protect people. Disease-specific median reductio...

This study estimates the impact of improved sanitation on diarrhoeal incidence among Nepalese children below the age of five. Using 2006 cross-sectional survey data from the DHS for Nepal, I employ non-parametric techniques to match children belonging to ”treatment” groups with children in a ”control” group without access to the facilities to explain the decline in diarrhea rates among children...
