20 世纪 90 年代初的调查证据普遍表明，美国老年人口的残疾率有所下降。由于证据并不完全一致，一些作者推测残疾下降是否会持续下去。本文报告了1999年国家长期护理调查的结果，显示了1982年至1999年的残疾趋势。发现1994年至1999年期间残疾率持续下降，并且1990年代的下降幅度大于1980年代。1982年至1989年的残疾率每年下降0.26%，1989年至1994年每年为0.38%，1994年至1999年为每年0.56%。此外，1989 年至 1999 年期间，黑人残疾率下降的比例高于非黑人。
Survey evidence through the early 1990s generally suggests a reduction in disability in the elderly population of the United States. Because the evidence is not fully consistent, several authors have speculated about whether disability declines will continue. This paper reports results from the 1999 National Long-Term Care Survey on disability trends from 1982 through 1999. It is found that disability continued to decline in the 1994 to 1999 period, and that the decline was greater in the 1990s than in the 1980s, The disability decline from 1982 to 1989 was 0.26% per year, from 1989 to 1994 it was 0.38% per year, and from 1994 to 1999 it was 0.56% per year. In addition, disability declined by a greater percentage for blacks than for nonblacks over the 1989 to 1999 period.
