This paper studies gender differences in disability free life expectancy (DFLE), taking into account mortality and disability contributions. After analysing the types of disability that account for such differences, it goes on to examine temporal variability and age contributions to mortality and disability variation. The method used is an extension of Arriaga's model proposed by Nusselder. In 2005, disability free life expectancy at age 30 was 46.23 years for men and 48.74 years for women, with a gender difference of 2.51 years. Decomposing this difference we find that the mortality effect is 3.70 years, while the disability effect is negative and equal to -1.19 years. Ten years earlier, in 1994, DFLE at age 30 was 43.24 years for men and 46.55 years for women, with a difference between genders of 3.32 years. This broke down to a mortality effect of 4.33 years and a disability effect of -1.02 years. In conclusion, the gap in DFLE between men and women is narrowing, thanks to the more rapid drop in mortality rates in men. With respect to disabilities women are disadvantaged, although the difference (in both total disability and different types of disability) has been almost stable in recent years.
本文研究了无残疾预期寿命(DFLE)方面的性别差异,同时考虑了死亡率和残疾因素。在分析导致此类差异的残疾类型后,文章接着考察了时间变异性以及年龄对死亡率和残疾率变化的影响。所采用的方法是对努塞尔德提出的阿里亚加模型的扩展。2005年,30岁男性的无残疾预期寿命为46.23年,女性为48.74年,性别差异为2.51年。对这一差异进行分解后我们发现,死亡率影响为3.70年,而残疾影响为负,等于 -1.19年。10年前,即1994年,30岁男性的无残疾预期寿命为43.24年,女性为46.55年,性别差异为3.32年。这一差异分解为死亡率影响4.33年和残疾影响 -1.02年。总之,由于男性死亡率下降更快,男女之间的无残疾预期寿命差距正在缩小。在残疾方面,女性处于劣势,尽管(在总残疾和不同类型残疾方面)近年来差异几乎保持稳定。
