BACKGROUND We examined socioeconomic inequalities in disability-free life expectancy in older men and women from England and the United States and explored whether people in England can expect to live longer and healthier lives than those in the United States. METHODS We used harmonized data from the Gateway to Global Aging Data on 14,803 individuals aged 50+ from the U.S. Health and Retirement Study (HRS) and 10,754 from the English Longitudinal Study of Ageing (ELSA). Disability was measured in terms of impaired activities and instrumental activities of daily living. We used discrete-time multistate life table models to estimate total life expectancy and life expectancy free of disability. RESULTS Socioeconomic inequalities in disability-free life expectancy were of a similar magnitude (in absolute terms) in England and the United States. The socioeconomic disadvantage in disability-free life expectancy was largest for wealth, in both countries: people in the poorest group could expect to live seven to nine fewer years without disability than those in the richest group at the age of 50. CONCLUSIONS Inequalities in healthy life expectancy exist in both countries and are of similar magnitude. In both countries, efforts in reducing health inequalities should target people from disadvantaged socioeconomic groups.

英格兰和美国老年人的无残障人均预期寿命中的社会经济不平等：一项基于人口的跨国研究。

背景技术我们研究了英格兰和美国的老年男性和女性在无残障人均预期寿命方面的社会经济不平等现象，并探讨了英国人是否可以期望比美国的人寿命更长，更健康。方法我们使用了来自美国全球健康与退休研究（HRS）的14803名年龄在50岁以上的人和来自英国纵向老龄化研究（ELSA）的10754人的全球老龄化网关的统一数据。残疾是根据受损的活动和日常生活中的工具活动来衡量的。我们使用离散时间多状态生命表模型来估计总预期寿命和无残障的预期寿命。结果在英格兰和美国，无残疾预期寿命中的社会经济不平等程度相似（绝对值）。在这两个国家，无残障人均预期寿命的社会经济劣势对财富而言是最大的：最贫穷的人群在50岁时的预期寿命比最富有的人群要少七至九岁。结论结论健康方面的不平等两国均存在预期寿命，并且寿命相似。在这两个国家，减少健康不平等的努力应针对弱势社会经济群体的人们。
