Research On How Accessibility To Safe Drinking Water Influence Health Of The Residents

Since the reform and opening up, China’s rapid economic development, ignoring the carrying capacity of the environment, drinking water safety issues caused by frequent incidents of water pollution have become increasingly prominent. At the same time, long-term exposure to contaminated environments, as well as use unsafe drinking water, to a certain extent, changed the habits of residents and improved the health of the shadow price, that not conducive to improving residents’ health needs. Although there are a large number of domestic and foreign literature research on how accessibility to safe drinking water influence health of the residents, but almost invariably only investigated the relationship between accessibility to safe drinking water and residents’health from a certain angle and the health indicators more single, few literature across the country, in a different perspective and the internal of perspective, select variety health indicators to analysis how accessibility to safe drinking water influence health of the residents.In this paper, after sorts out the research on accessibility to safe drinking water influence health of the residents nowadays, analyzes the condition and regional differences on accessibility to safe drinking water, residents’ health status and differences. Then using Chinese45years old and above residents as the research object, on the basis of relevant theories and draw on existing research, based on the overall perspective, the level of regional perspective, the age structure perspective, the perspective of differences gender and income hierarchical perspective, to establish binary Logit model researching the affect of safe drinking water on residents’health. Through indepth analysis how accessibility to safe drinking water influence health of the residents for government at different stages of economic development and urbanization of the population by addressing the problem of accessibility to safe drinking water to improve residents’health status put forward policy recommendations.The results of this study indicate that:(1) Through the analysis of the current situation of accessibility to safe drinking water and regional differences, we find that there are many water shortage areas in China, a large number of industrial wastewater emissions, using agricultural fertilizer and pesticide causing the water environmental quality in a sharp falling. There exists obvious urban-rural differences of accessibility to safe drinking water, in the urban cities, accessibility to safe drinking water generally reached more than90%, and the highest and lowest areas differ by63.4%. In the most of the rural areas accessibility to safe drinking water less than60%, and the highest and lowest areas differ by88%. There also exists regional differences of accessibility to safe drinking water, in the eastern cities, accessibility to safe drinking water is98.7%, the central cities is80.9%, the western cities is86.7%. In the eastern rural areas, accessibility to safe drinking water is98.7%, the central rural areas is38.1%, the western rural areas is44.4%.(2) From the statistical analysis we find, there exist close relationship between accessibility to safe drinking water and residents’ health. Preliminary analysis shows, there exist good health benefits between accessibility to safe drinking water and residents’ health. At the same time, we find that low income residents’health poor than high income residents’health, this may probably of high income residents more easy to obtain safe drinking water.(3) This paper use chronic illness, a month sickness, a year of hospitalization and self-reported health as the overall health of the residents, using whether the family has piped water as the safe drinking water’indicator. Regression results show that, the accessibility to safe drinking water is a key factor in determining the health status of individuals, on the whole, a10%increase in piped water will lead to1.02%and1.94%decrease in the chronic diseases and a month sickness, piped water reduced a year of hospitalization rates for and improved the level of self-repored health.(4) Further research find there exists rigional, nonelderly-elderly, gender and income differences in the relationship between accessibility to safe drinking water and health. Accessibility to safe drinking water significantly reduce the nonelderly and women in chronic diseases and a month sickness at the level of1%and5%, its effect will decline as the income rise. Accessibility to safe drinking water also significantly reduce the rural residents in chronic diseases and a month sickness at the level of5%and1%, significantly reduce the western residents in chronic diseases t the level of1%.(5) From the overall perspective and regional levels, age structure, sex differences and income perspective, we find that piped water has the most obvious affect on chronic diseases, Studies have shown that long-term using low polluted dringking water may not appear obvious unhealthy symptoms in the short-term, but in the long-term will lead to suffer various chronic diseases.Compared to the existing literature, this paper has the following three main contributions:First, analysis the condition and regional differences on accessibility to safe drinking water, reveal the reasons of regional differences. Second, select national baseline survey data, use multiple health indicators and expand research perspective to reduce the may exist research bias on data regionalization, health indicators and research perspective simplification.Three, this article analyzes not only the direct impacts how accessibility to safe drinking water influence health of the residents, but also through region、age、gender and income analyzes its influence health of the residents.
