WHO Study on Global AGEing and Adult Health (SAGE): Wave 0, 2002-2004

The World Health Organization (WHO)'s Study on Global Ageing and Adult Health (SAGE) is a longitudinal follow-up of a cohort of ageing and older adults. SAGE has been built on the experience and standardized instruments of WHO's 2000/2001 Multi-country Survey Study (MCSS) and the 2002/2004 World Health Surveys (WHS). These surveys focused on health and health-related outcomes and their determinants and impacts in nationally representative samples. These data aim to address data gaps on ageing, adult health and well-being in lower and middle income countries, whilst being comparable to surveys conducted in higher income countries (such as the Health and Retirement Study (HRS), English Longitudinal Study of Ageing (ELSA), and the Survey of Health, Ageing and Retirement in Europe (SHARE)). One of the major drivers of this effort has been the lack of comparability of self-reported health status in international health surveys due to systematic biases in reporting, despite using similar instruments and attempts at making questions conceptually equivalent in translation. SAGE uses standard instruments developed over the last decade, a common design and training approach with explicit strategies for making data comparable to cover a wide range of issues that directly and indirectly impact health and well-being. The survey methodology and research design has included a number of methods to address methods for detecting and correcting for systematic reporting biases in health interview surveys, including vignette methodologies, objective performance tests and biomarkers. A number of techniques have also been employed to improve data comparability, including using common definitions of concepts, common methods of data collection and translations, rigorous sample design and post hoc harmonization. The 2002-2004 WHS data from six countries (China, Ghana, India, Mexico, Russia, and South Africa) constitute Wave 0 of WHO's Study on Global Ageing and Adult Health (SAGE). A sample of these respondents were included in the follow-up 2007-2010 SAGE Wave 1 in these six countries, with new respondents added to ensure a nationally representative sample.

世界卫生组织（World Health Organization, WHO）的全球老龄化与成人健康研究（Study on Global Ageing and Adult Health, SAGE）是针对老龄化及老年人群队列开展的纵向追踪研究。SAGE依托世界卫生组织2000/2001年多国家调查研究（Multi-country Survey Study, MCSS）与2002/2004年世界卫生调查（World Health Surveys, WHS）的实践经验与标准化调研工具。此前的相关调查均以具有全国代表性的样本为研究对象，聚焦健康及健康相关结局、其决定因素与影响。本数据集旨在填补中低收入国家在老龄化、成人健康与福祉领域的数据空白，同时可与高收入国家开展的同类调查（如健康与退休研究（Health and Retirement Study, HRS）、英国老龄化纵向研究（English Longitudinal Study of Ageing, ELSA）以及欧洲健康、老龄化与退休调查（Survey of Health, Ageing and Retirement in Europe, SHARE））开展可比分析。此项工作的核心动因之一在于：尽管国际健康调查采用了相似的调研工具，并尝试在翻译环节实现问题的概念等效，但因报告过程中的系统性偏差，自我报告健康状况的国际可比性仍存在显著不足。SAGE采用近十年间研发的标准化工具、统一的研究设计与培训方案，并配套明确的数据可比化作法，覆盖一系列直接或间接影响健康与福祉的广泛议题。本次调查的方法学与研究设计纳入了多种用于检测并校正健康访谈调查中系统性报告偏差的手段，包括情境测试法（vignette methodologies）、客观性能测试与生物标志物检测。此外，团队还采用多项技术提升数据可比性，例如统一概念定义、标准化数据收集与翻译流程、严谨的抽样设计以及事后数据协调。来自中国、加纳、印度、墨西哥、俄罗斯与南非6个国家的2002-2004年WHS数据，构成了世界卫生组织全球老龄化与成人健康研究（SAGE）的第0波次（Wave 0）。在上述6国中，部分受访对象被纳入2007-2010年开展的SAGE第1波次追踪调查，同时新增受访对象以确保样本具备全国代表性。

背景概述

该数据集是WHO全球老龄化和成人健康研究（SAGE）的Wave 0阶段，覆盖2002-2004年，基于六个国家（中国、加纳、印度、墨西哥、俄罗斯和南非）的世界健康调查数据，旨在填补中低收入国家老龄化健康数据的空白。其特点包括使用标准化工具和纵向设计，通过概率抽样获取全国代表性成人样本，并整合了自报健康、性能测试和生物标志物等多种方法，以增强数据的国际可比性和可靠性。
