背景本研究提出了一个新的概念，双功能，整合身体和认知功能。我们使用的概念来定义一个衡量的双功能预期寿命（2FLE）和评估种族，民族的不平等aging.MethodsDrawing从全国健康访谈调查相关死亡率文件和健康和退休研究的数据，我们定义的双重功能，没有限制的日常生活活动和免费的痴呆症。我们使用该指标和沙利文生命表来估计4个种族-民族和出生群体中女性和男性的50岁总预期寿命和50岁2 FLE。结果在50-54岁之间，79.0%（95% CI：73.5，84.5）和87.6%（95% CI：84.0，91.2）（非西班牙裔）黑人、外国出生的西班牙裔和美国-出生的西班牙裔女性和男性保持双重功能，而（非西班牙裔）白色女性和男性分别为90.4%（95% CI：89.3，91.4）和91.4%（95% CI：90.2，92.5）。这些以及85岁及以上双重功能中相应的种族-民族差异转化为2FLE中的巨大不平等。例如，50岁2FLE的黑人-白人差距为女性6.9年（95% CI：-7.5，-6.4），男性6.0年（95% CI：-6.6，-5.4）。据估计，出生的西班牙裔老年人在其剩余岁月中具有双重功能的比例小于白色老年人。这些结果揭示了老龄化中明显的种族-民族不平等，对生活质量、生育和健康需求有重大影响。
BackgroundThis study develops a new concept, dual functionality, that integrates physical and cognitive function. We use the concept to define a measure of dual-function life expectancy (2FLE) and assess racial–ethnic inequalities in aging.MethodsDrawing on data from the National Health Interview Survey Linked Mortality Files and the Health and Retirement Study, we define dual functionality as having no limitations in activities of daily living and being free of dementia. We use this measure and Sullivan life tables to estimate age-50 total life expectancy and age-50 2FLE for women and men across 4 racial–ethnic and nativity groups.ResultsAt ages 50–54, between 79.0% (95% CI: 73.5, 84.5) and 87.6% (95% CI: 84.0, 91.2) of (non-Hispanic) Black, foreign-born Hispanic, and U.S.-born Hispanic women and men remain dual functional as compared with 90.4% (95% CI: 89.3, 91.4) and 91.4% (95% CI: 90.2, 92.5) of (non-Hispanic) White women and men, respectively. These and corresponding racial–ethnic disparities in dual functionality through ages 85 and older translate into substantial inequalities in 2FLE. For instance, the Black–White gap in age-50 2FLE is 6.9 years (95% CI: −7.5, −6.4) for women and 6.0 years (95% CI: −6.6, −5.4) for men.ConclusionsBlack, foreign-born Hispanic, and U.S.-born Hispanic older adults are estimated to live a smaller percentage of their remaining years with dual functionality than White older adults. These results reveal stark racial–ethnic inequalities in aging that have significant implications for quality of life, caregiving, and health needs.
