目标。考察40年来(1970-2010年)美国所有年龄段男性和女性的预期寿命、残疾预期寿命和非残疾预期寿命的变化。我们使用了美国生命统计的死亡率和国家健康访谈调查中社区居住人口中残疾流行率的数据；对于机构人口，我们计算了美国人口普查中的残疾流行率。我们使用Sullivan方法估计1970年、1980年、1990年、2000年和2010年的残废和非残废预期寿命。40年来，无残疾预期寿命和残疾预期寿命均稳步增长。男性出生时残疾寿命的增加与非残疾寿命的增加相同(4.5岁)；女性出生时残疾寿命的增加(3.6岁)超过非残疾寿命的增加(2.7岁)。在65岁时，无残疾寿命的增加大于残疾寿命的增加。在整个生命周期中，没有压迫的发病率，但在65岁时出现了一些压迫。
Objectives. To examine changes over 40 years (1970-2010) in life expectancy, life expectancy with disability, and disability-free life expectancy for American men and women of all ages.Methods. We used mortality rates from US Vital Statistics and data on disability prevalence in the community-dwelling population from the National Health Interview Survey; for the institutional population, we computed disability prevalence from the US Census. We used the Sullivan method to estimate disabled and disability-free life expectancy for 1970, 1980, 1990, 2000, and 2010.Results. Over the 40 years, there was a steady increase in both disability-free life expectancy and disabled life expectancy. At birth, increases in disabled life and non-disabled life were equal for men (4.5 years); for women, at birth the increase in life with disability (3.6 years) exceeded the increase in life free of disability (2.7 years). At age 65 years, the increase in disability-free life was greater than the increase in disabled life.Conclusions. Across the life cycle, there was no compression of morbidity, but at age 65 years some compression occurred.
