DESCRIPTION (provided by applicant): Household air pollution (HAP) is a top-priority public health problem in developing countries. According to the most recent comparative risk assessment, 3.5 million people die prematurely each year as a result of HAP exposures. While uncertainties remain regarding causal links between HAP exposures and health, the time is ripe for focused research into effective interventions. Limited past research has shown that the demand for clean cookstoves is low, and that households continue to use traditional hearths even when they have clean stoves. These behaviors threaten to undermine cookstove intervention programs, such as those promoted by the Global Alliance for Clean Cookstoves. We propose to harness an existing cohort in Ghana to study factors that increase the adoption of clean cookstoves, and to test strategies to promote adoption and continued use. Our work draws heavily on the availability of reliable low cost stove use monitors (SUMS), which record stove temperature and other key parameters to provide an objective measure of daily use over long periods of time. Additionally, our work examines the adoption both of efficient biomass cookstoves and liquefied petroleum gas (LPG). Our study is structured around four main activities. First, we will measure stove use in our current intervention (n=1415) and test a series of hypotheses about household characteristics that predict increased use of clean stoves. Second, we will assess the effects of stove type and usage on household time allocation using time activity diaries, to test the hypothesis that clean cookstoves free up substantial time for household members, particularly women. Third, we will carry out a small-randomized trial to test the effects of health education delivered by community health workers and by local opinion leaders. Finally, we will use a simple bidding procedure to elicit willingness-to-pay (WTP) for high efficiency cookstoves, and will examine how WTP varies in function of the way in which the stove is marketed. Collectively, these activities will substantially enhance the knowledge base for effective household energy interventions that reduce air pollution exposures and prevent disease.

描述（由申请人提供）：家庭空气污染（HAP）是发展中国家最优先的公共卫生问题。根据最近的比较风险评估，每年有350万人因接触HAP而过早死亡。虽然接触HAP与健康之间的因果关系仍存在不确定性，但对有效干预措施进行集中研究的时机已经成熟。过去有限的研究表明，对清洁炉灶的需求很低，即使有了清洁炉灶，家庭仍继续使用传统炉灶。这些行为有可能破坏炉灶干预计划，例如全球清洁炉灶联盟所推动的计划。我们建议利用加纳现有的队列来研究增加清洁炉灶采用的因素，并测试促进采用和继续使用的策略。我们的工作很大程度上依赖于可靠的低成本炉子使用监视器（sum），它记录炉子温度和其他关键参数，以提供长期日常使用的客观测量。此外，我们的工作考察了高效生物质炉灶和液化石油气（LPG）的采用。我们的研究围绕四个主要活动展开。首先，我们将测量当前干预中炉子的使用情况（n=1415）并进行一系列测试
