Measurement of health and disability trends, compression of morbidity aging study

说明(由申请人提供)：2001年，国家研究委员会认识到需要对老龄化问题进行多学科研究和纵向研究，强调跨国家研究可以为政策提供比单一国家研究多得多的有用证据。理事会还强调需要统一各国的数据收集并使之标准化。在2008年最近的一份出版物中，它强调，“在社会调查中纳入生物指标将……鼓励更广泛的综合思维，加深对机制和因果联系的理解”。正是出于这一目的，世卫组织关于全球老龄化和成人健康的研究(SAGE)使用了一套方法来提供可比的跨国数据，这些数据可以与美国的健康和退休研究(HRS)等工作进行比较。这项拟议的研究旨在衡量世界卫生组织(WHO)S全球老龄化与成人健康研究(SAGE)中老年队列中残疾(被理解为非致命性健康后果)的趋势。其目的是改进对家庭调查环境中的非致命性健康结果、慢性病和风险因素的衡量，并审查非致命性健康结果及其决定因素(如慢性病和风险因素)与包括死亡率在内的未来健康结果之间的联系。它还旨在研究低收入和中等收入国家老龄人口的经济活动、生活质量、幸福感和非致命性健康结果之间的关系。通过改进对发病率的衡量和随着时间的推移跟踪答复者，它将试图回答与老龄人口未来健康有关的关键问题。第三波数据将提供至少3个数据点，对于一些受访者来说，将提供4个数据点(SAGE波0-3)。参与国覆盖的人口占世界60岁及以上人口的40%以上。这项研究的数据将对了解美国老年人的健康状况产生直接影响，特别是那些来自较低社会经济阶层的老年人和健康状况最差的少数群体。拟议的研究将向研究人员提供所有匿名的微观数据，并按照现行标准提供所有元数据的完整文件。

DESCRIPTION (provided by applicant): The National Research Council in 2001, recognizing the need for multi-disciplinary research and longitudinal studies on aging, emphasized that cross-national studies can provide substantially more useful evidence for policy than can single country studies. The Council also stressed the need for harmonizing and standardizing data collection across countries. In a more recent publication in 2008, it stressed that "including biological indicators in social surveys will ....encourage broader integrative thinking and produce deeper understanding of mechanisms and causal linkages". It is with this intent that WHO's Study on Global Ageing and Adult Health (SAGE) has been designed using a set of methods to provide comparable cross-national data that can be compared to efforts in the US such as the Health and Retirement Study (HRS). The proposed study aims to measure trends in disability (understood as non-fatal health outcomes that capture a state less than full health) in aging cohorts in the World Health Organization (WHO)'s Study on Global Aging and Adult Health (SAGE) across the age range of older adults. It aims to do this by improving the measurement of non-fatal health outcomes, chronic diseases and risk factors in household survey settings and examine the links between non-fatal health outcomes, their determinants such as chronic disease and risk factors and future health outcomes including mortality. It also aims to examine the relationship between economic activity, quality of life, well-being and non-fatal health outcomes in aging populations in low and middle income countries. By improving the measurement of morbidity and tracking respondents over time it will attempt to answer the critical questions related to the future health of ageing populations. Wave 3 data will provide at least 3, and for some respondents 4, data points (SAGE Waves 0-3). The populations covered by participating countries covers over 40% of the world's population aged 60 years and older. Data from the study will have direct implications for understanding the health of older adults in the US, especially those from lower socioeconomic classes and minority populations that are at greatest risk of poor health. The proposed study will make all anonymized micro data available to researchers along with a full documentation of all metadata as per current standards.
