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

描述（由申请人提供）：2001年，国家研究理事会认识到需要对老龄化进行多学科研究和纵向研究，强调跨国研究可以为政策提供比单一国家研究更有用的证据。理事会还强调需要协调各国的数据收集工作并使之标准化。在2008年最近的一份出版物中，它强调，“将生物指标纳入社会调查将.。鼓励更广泛的综合思维，加深对机制和因果关系的理解”。正是出于这一目的，世卫组织的全球老龄化和成人健康研究（SAGE）采用一套方法设计，以提供可与美国的健康和退休研究（HRS）等工作进行比较的可比跨国数据。这项拟议的研究旨在衡量世界卫生组织（WHO）全球老龄化和成人健康研究（SAGE）中老龄化队列中老年人年龄范围内的残疾趋势（理解为非致命性健康结果，即捕获不到完全健康的状态）。其目的是通过在住户调查中改进对非致命性健康结果、慢性病和风险因素的计量来做到这一点，并审查非致命性健康结果、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化人口的经济活动、生活质量、福祉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长期跟踪调查对象，它将试图回答与老龄人口未来健康有关的关键问题。第3波数据将提供至少3个数据点，有些答复者将提供4个数据点（SAGE第0-3波）。参与国覆盖的人口占世界60岁及以上人口的40%以上。该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，特别是那些来自社会经济地位较低的人群和健康状况不佳风险最大的少数群体。拟议的研究将向研究人员提供所有匿名的微观数据沿着按照现行标准提供所有元数据的完整文档。 公共卫生相关性随着全球人口和流行病的迅速转变，包括在低收入和中等收入国家，迫切需要生成关于老年人群体健康、财富和福祉动态的数据，这些数据在不同人群之间和不同时间具有可比性。从这些研究中获得的见解将有助于规划医疗保健和社会政策，以保持人口健康，并在他们继续长寿时保持他们的福祉。这些研究还将有助于提高我们对老年人健康和幸福的决定因素的理解。可以确定一些重要战略，以防止老年群体的健康不良和残疾负担，以及扩大慢性病的保健，从而促进福祉和提高生活质量。作为拟议研究的一部分，收集的数据也被设计为与高收入国家和不同人口财富水平的类似研究相比较。

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. PUBLIC HEALTH RELEVANCE With the rapid demographic and epidemiological transition occurring globally, including in low and middle income countries, there is an urgent need to generate data with regard to the dynamics of health, wealth and well-being in the older adult segment of the population that is comparable across populations and over time. Insights obtained from such studies will help plan health care and social policy to keep populations healthy and maintain their well-being as they continue to live longer. These studies would also help to improve our understanding of the determinants of health and happiness into older ages. Important strategies to prevent the burden of ill-health and disability in older age groups, as well as to extend health care for chronic diseases, can be identified to promote well-being and improve quality of life. Data collected as part of the proposed study have also been designed to be comparable to similar studies in higher income countries and across levels of population wealth.
