Integrated Demographic and Health Survey Data for Population Health Research

项目摘要/摘要 这项提案寻求继续提供资金，以扩大和加强IPUMS国土安全部，从而消除过度- 利用世界上运行时间最长的人口与健康调查(DHS)进行的时间和跨国分析 关于低收入和中等收入国家健康和生育率的调查系列。借助强大的数据发现工具， 数以千计的协调变量、易于获取的文档以及社会和环境背景 变量链接到单个记录，IPUMS DHS极大地降低了成本，增加了范围，严谨， 以及人口健康研究的可重复性。IPUMS国土安全部的时间和地理范围 数据库支持关于生育、避孕、新生儿等主题的尖端人口健康研究 以及五岁以下儿童死亡率、低出生体重、儿童发育迟缓和消瘦、腹泻、营养、食品安全、肥胖、 危险的性行为、获得保健、妇女赋权、亲密伴侣暴力、水和 环境卫生，以及武装冲突对生殖选择的影响。建议的创新和扩展 下一阶段数据库的更新将指数级地增加IPUMS支持的潜在研究主题 国土安全部。续建项目有五个具体目标：目标1.实现全球覆盖。IPUMS国土安全部现在 纳入了来自41个非洲和亚洲国家的170项国土安全部调查的微观数据，但还不包括 拉丁美洲、加勒比、中亚和东亚、东欧或大洋洲。下一阶段将添加 来自新地区的调查系列，同时也增加了来自非洲和南亚的最新调查。目标2.解锁 跨IPUMS全球健康数据库的比较研究。IPUMS国土安全部将变得更加强大 在数据库可与其他全球健康数据系列互操作的下一阶段，例如 儿童基金会的多指标类集调查(MIC)。与来自MICS的数据相结合，几乎90%的 国土安全部国家将有三个或更多样本可以跨时间进行比较，98%的国家将拥有来自 21世纪。目标3.推动关于社会和环境背景对以下方面影响的前沿研究 健康。第三个项目阶段将使综合方案管理系统中的社会和环境背景变量的数量增加两倍 国土安全部。有了这些新数据，研究人员将进行开创性的研究，例如对 海平面上升对海岸线附近社区个人健康的影响。目标4.加快数据传输 通过简化或消除研究人员的数据管理任务进行分析。拟议的增强功能将 使用户能够根据主题内容、可变可用性和国家/地区特征过滤样本。我们会 还开发了应用程序编程接口(API)，允许用户自动执行定义和 正在执行数据提取。目标5.支持和扩大我们的用户社区。IPUMS国土安全部致力于 使人口数据的获取民主化。该项目将继续提供强有力的个性化用户支持， 在关键会议上举办网络研讨会和讲习班，同时介绍在线教程和代码共享机会。

Project Summary/Abstract This proposal seeks continued funding to expand and enhance IPUMS DHS, which eliminates barriers to over- time and cross-national analyses with the Demographic and Health Surveys (DHS), the world's longest running survey series on health and fertility in low- and middle-income countries. With powerful data discovery tools, thousands of harmonized variables, easy-to-access documentation, and social and environmental context variables linked to individual records, IPUMS DHS dramatically reduces the cost and increases the range, rigor, and reproducibility of research on population health. The temporal and geographic scope of the IPUMS DHS database enables cutting-edge population health research on topics including fertility, contraception, neonatal and under-five mortality, low birth weights, child stunting and wasting, diarrhea, nutrition, food safety, obesity, risky sexual behavior, access to health care, women’s empowerment, intimate partner violence, water and sanitation, and the impact of armed conflict on reproductive choices. The proposed innovations to and expansion of the database in the next phase will exponentially increase the potential research topics enabled by IPUMS DHS. The continuation project has five specific aims: Aim 1. Achieve global coverage. IPUMS DHS now incorporates microdata from 170 DHS surveys from 41 African and Asian countries, but it does not yet cover Latin America, the Caribbean, Central and East Asia, Eastern Europe, or Oceania. The next phase will add survey series from new regions, while also adding the latest surveys from Africa and South Asia. Aim 2. Unlock comparative research across IPUMS global health databases. IPUMS DHS will become even more powerful in the next phase when the database is made interoperable with other global health data series, such as UNICEF’s Multiple Indicator Cluster Surveys (MICS). When coupled with data from MICS, almost 90 percent of DHS countries will have three or more samples to compare across time, and 98 percent will have data from the 21st century. Aim 3. Enable cutting-edge research on the impact of social and environmental context on health. The third project phase will triple the number of social and environmental context variables in IPUMS DHS. With these new data, researchers will conduct path-breaking research, such as global comparisons of the impact of rising sea levels on the health of individuals in communities near coastlines. Aim 4. Expedite data analysis by simplifying or eliminating researchers’ data management tasks. Proposed enhancements will enable users to filter samples based on topical content, variable availability, and country characteristics. We will also develop an Application Programming Interface (API), allowing users to automate the tasks of defining and executing data extracts. Aim 5. Support and expand our user community. IPUMS DHS is committed to democratizing access to population data. The project will continue to provide robust individualized user support, webinars, and workshops at key conferences, while introducing online tutorials and code-sharing opportunities.
