Bottled water is a rapidly growing yet relatively understudied source of drinking water globally. In addition to concerns about the safety of bottled water, the adverse environmental health and social impacts associated with bottled water production, distribution, consumption, and reliance are considerable. Our objective was to comprehensively revi...

BACKGROUND: Inadequate access to safe drinking water remains a global health problem, particularly in rural areas. Boiling is the most commonly used form of point-of-use household water treatment (HWT) globally, although the use of bottled water in low-and middle-income countries (LMICs) is increasing rapidly. OBJECTIVES: We assessed the regional...
Article
Intermittent water supply (IWS) is a relatively common phenomenon across the world as well as in rural and peri-urban areas across China, though there has been little IWS-focused research from China published to date. IWS consumers typically adopt a range of strategies to cope with insufficient water supply, poor drinking water quality, and associa...
Article
Context: Appalachia, a socioeconomically disadvantaged rural region in the eastern U.S., has one of the nation's highest prevalence rates of smoking and some of the poorest health outcomes. Effective interventions that lower smoking rates in Appalachia have great potential to reduce health disparities and preventable illness; however, a better und...
Article
The application of Water Safety Plans (WSPs) in China varies throughout the country. Although pilot WSP projects in China were initiated shortly after WSP was introduced by the World Health Organization (WHO) in 2004, they have yet to be used for water supply facilities at a large scale. To better understand the evolution of WSP application in Chin...

In China, achieving rural drinking water safety—meaning access to a safe, affordable, sufficient, and sustainable drinking water supply—remains a key challenge for government agencies and researchers. Using cross-sectional data at the provincial level, in this paper we examine the impacts of socioeconomic development on drinking water safety in rur...
Article
Full-text available
The rapid growth of bottled water use in low- and middle-income countries, and its normalization as a daily source of drinking water, does not provide a pathway for universal access. Generous and sustained investment in centralized and community utilities remains the most viable means for achieving safe water access for all. OPEN-ACCESS LINK TO PA...

Globally, approximately 2 billion people lack microbiologically safe drinking water. Boiling is the most prevalent household water treatment method, yet evidence of its health impact is limited. To conduct this systematic review, we searched four online databases with no limitations on language or publication date. Studies were eligible if health o...

目的 了解农村家庭饮水行为现状及影响因素,探讨除烧开水以外有效的饮用水处理方法。方法 通过面对面问卷调查方式,于2013—2014年对广西2个县的450户家庭进行调查,收集十类与农村家庭饮用水相关的指标情况,多因素logistic回归分析农村家庭饮用水行为的影响因素。结果 调查的450户农村家庭中,47.5%的家庭烧开水,35%喝桶装水,17.5%喝生水。A县喝开水率显著高于B县(χ2=9.547,P=0.002)。多因素logistic回归分析结果显示,影响农村居民烧开水的因素包括知识水平(OR=0.290,95%CI=0.097~0.865)、污水处理(OR=0.295,95%CI=0.112~0.776)、储存水(OR=0.059,95%C=:0.013~0.269)、喝开水态度(OR...

Approximately two billion people drink unsafe water. Boiling is the most commonly used household water treatment (HWT) method globally and in China. HWT can make water safer, but sustained adoption is rare and bottled water consumption is growing. To successfully promote HWT, an understanding of associated socioeconomic factors is critical. We coll...

Background: In rural China ~607 million people drink boiled water, yet little is known about prevailing household water treatment (HWT) methods or their effectiveness. Boiling, the most common HWT method globally, is microbiologically effective, but household air pollution (HAP) from burning solid fuels causes cardiovascular and respiratory diseas...

Introduction to the Multidimensional Poverty Assessment Tool and related resources (2014)
Article
This article discusses the participatory creation of the Multidimensional Poverty Assessment Tool (MPAT), a survey-based thematic indicator developed in China and India. The core of the article focuses on the use of expert elicitation to inform the construction of MPAT’s household and village surveys, the cardinalisation of survey responses, and th...
Article
The Multidimensional Poverty Assessment Tool (MPAT) measures fundamental dimensions of rural poverty in order to support poverty-alleviation efforts in the less developed world. This article's primary purpose is to introduce MPAT and describe its theoretical rationale. It begins with an overview of the importance of creating enabling environments f...
Article
This paper describes the theoretical foundations and development of a multidimensional, water-focused, thematic indicator of rural poverty: The Water, Economy, Investment and Learning Assessment Indicator (WEILAI). The WEILAI approach was specifically designed for application in rural China, to support poverty alleviation project planning, monitori...
