Social-epidemiological study for evaluation of water supply and sanitation systems of low-income urban community in Dhaka, Banglades

摘要

This study aims at quantification of health losses, considering social and environmental factors.nMorbidity and mortality cases of diarrhoea for children under five years old were used to estimatenthe disability adjusted life years (DALYs) lost for the target households in low-income communitiesnin Dhaka, Bangladesh. Water supply facilities and sanitation systems, along with hygiene practicesnand their health outcomes, were studied at community level. Demographic, socio-economic andnsocio-cultural aspects were also studied to support the research findings and give a betternunderstanding of the local conditions. The four selected communities, Ward 60 (W60), Ward 61n(W61), Ward 62 (W62) and Ward 65 (W65), all had different existing urban services such as waternsupply, sanitation, garbage management and drainage facilities. All of these services existed innW62, but W60 did not have any of the services; W61 had sanitation and drainage coverage,nwhereas W65 had only a water supply facility. The results conclusively showed that, comparednwith the null (absence of services) scenario (W60), the other three scenarios (W61, W62 and W65)nshowed a substantial decrease of diarrhoea (1.219, 1.284 and 2.052 DALYs/household/year,nrespectively) reported for children under five years old. Besides urban services, othernsocio-economic characteristics might also influence the prevalence of diseases.
