Record life expectancy does not appear to be approaching its limit-it is still increasing, as is the maximum life span. An important question is whether the longer life is accompanied by an increasing lifetime in good health. The aim of the study was to determine the trends in health expectancy at age 65 in Denmark during the period 1987-2005, including the end of a period of stagnation (until 1995) and the beginning of a new period with increasing life expectancy (after 1994). The study was based on nationwide register data on mortality and data on health status from the Danish Health Interview Surveys carried out in 1987, 1994, 2000, and 2005. Expected lifetime in various health states was estimated with Sullivan's method. Life expectancy at age 65 increased only after 1994 by almost 2 years among men and by about 1 year among women. The increase in expected lifetime without long-standing, limiting illness, lifetime without functional limitations, and lifetime with self-rated good health was all substantial in both genders (1.4-3 years depending on gender and health indicator), and was followed by a decrease in lifetime with the unhealthy state resulting in increasing proportions of lifetime in a healthy state. Overall, expected lifetime in good health increased more than life expectancy in both genders during the second half of the period 1987-2005, i.e. after the stagnation period.
有记录的预期寿命似乎并未接近其极限——它仍在增长，最高寿命也是如此。一个重要的问题是，寿命延长的同时健康寿命是否也在增加。本研究的目的是确定1987年至2005年期间丹麦65岁人群的健康预期寿命趋势，包括停滞期（至1995年）的结束以及预期寿命开始增长的新阶段（1994年后）。该研究基于全国范围的死亡率登记数据以及1987年、1994年、2000年和2005年丹麦健康访谈调查的健康状况数据。采用沙利文方法估算了处于各种健康状态下的预期寿命。65岁时的预期寿命仅在1994年后有所增加，男性增加了近2岁，女性增加了约1岁。在无长期限制性疾病的预期寿命、无功能限制的预期寿命以及自评健康良好的预期寿命方面，两性均有显著增加（根据性别和健康指标，增加幅度为1.4至3岁），随后不健康状态下的预期寿命下降，导致健康状态下的预期寿命比例增加。总体而言，在1987年至2005年下半年，即停滞期之后，两性健康良好状态下的预期寿命增长幅度超过了预期寿命。
