Water, Waste, and Well-Being: A Multicountry Study

摘要: Data collected in the late 1980s from eight countries Sub-Saharan Africa (Burundi, Ghana, Togo, and Uganda), Asia/North (Sri Lanka Morocco), Americas (Bolivia Guatemala) were combined analyzed to test whether incremental health effects regarding diarrhea nutritional status result improvements water sanitation conditions. Rural (n = 11,992) urban 4,888) samples separately. Optimal (i.e., on premises) intermediate (improved public water) supplies compared with unimproved (flush toilets or water-seal latrines) (latrines) levels sanitation. Nationally representative (random) of ever-married women aged 15-49 years, without children, interviewed all countries, children 3-36 months available weight height data included analyses. Multiple linear regression controlled for household, maternal, child-level variables ; addition, dummy each country. Improvements resulted less taller heavier three supply. Incremental benefits associated additional increases weights heights children. The improved greater among dwellers than rural dwellers. Health pronounced those Benefits occurred only when was optimal present. These findings suggest that interventions should balance epidemiologic cost services demand water. There be efforts develop compatible technologies so service can made.
