Global comparisons and large samples are needed to inform policy makers about aging trends among people aged older than 60 years. Using harmonized data gathered from the Gateway to Global Aging data, we introduce a new framework to measure healthy aging across 13 OECD countries.
First, we developed an original measure of physiological age (PA), that is, a measure of age weighted for the influence of frailty, activities of daily living limitations, and comorbidities. Second, we compared healthy aging measures across 13 countries based on a ranking of the countries according to the discrepancy between estimated PA and chronological age (CA). Third, we explored the socioeconomic factors associated with healthy aging.
We found a strong correlation between our PA measure and biological age. Italy, Israel, and the United States are the 3 countries where PA is the highest (independent of CA), thus indicating aging in poor health. In contrast, Switzerland, The Netherlands, Greece, Sweden, and Denmark have much lower PA than CA, thus indicating healthy aging. Finally, the PA-CA discrepancy is higher among poorer, less educated, and single older individuals.
Countries with higher PA need to implement or reinforce healthy aging measures and target the disadvantaged populations.
需要进行全球比较和大样本研究，为决策者提供有关 60 岁以上人群老龄化趋势的信息。本研究利用全球老龄化数据网关收集的协调数据，提出了一种衡量 13 个经合组织国家健康老龄化的新框架。
首先，我们开发了一种生理年龄（PA）的原始衡量标准，即根据虚弱、日常生活活动受限和合并症对年龄的影响进行加权的衡量标准。其次，我们根据各国根据估计的 PA 与实际年龄（CA）之间的差异进行排名来比较 13 个国家的健康老龄化衡量标准。第三，我们探讨了与健康老龄化相关的社会经济因素。
我们发现我们的 PA 衡量标准与生物学年龄之间存在很强的相关性。意大利、以色列和美国是 PA 最高的 3 个国家（独立于 CA），这表明健康状况不佳的老龄化。相比之下，瑞士、荷兰、希腊、瑞典和丹麦的 PA 远低于 CA，表明健康老龄化。最后，PA-CA 差异在较贫穷、受教育程度较低和单身的老年人中更高。
PA 较高的国家需要实施或加强健康老龄化措施，并针对弱势群体。
