Abstract
Objective To study impact of cognitive impairment on the life expectancy ( LE ), active life expectancy ( ALE ) and ALE/LE ratios in ≥ 60-year Beijing urban and rural population. Methods The samples were derived from Beijing Multidimensional Longitudinal Study on Aging. The subjects were the≥ 60-year population from Xuanwu district ( urban areas ), Daxing district ( plain ) and Huairou district ( mountain areas ) in Beijing. The assessment of cognitive function was conducted in 2111 subjects in 2009 by using the Mini Mental State Scale. The samples were followed up in 2011. Health or not was assessed according to whether the patients independently completed the activities of daily living ( ADL). The LE, ALE and ALE/LE in each age stage in a cognitive impairment group and the non-cognitive impairment group were calculated by using the multi-state life table ( IMaCH software ). Results There were 312 old people with cognitive impairment among the 2111 elderly. ①Both LE and ALE of the elderly women in Beijing were higher than men, and urban population had a higher LE and ALE than rural areas. The LE-.ALE and ALE/LE of the elderly with cognitive impairment were lower than normal cognitive group. ②In the cognitive impairment group,the LE and ALE of the urban younger aged male ( <70 years ) were significantly lower than the same age group of women. Regardless of region and gender, people over 80 years had the lowest LE and ALE. LE and ALE of the female decreased more than that of male. ③The ratio of ALE/LE of male was higher than female, as well as higher in urban elderly. The ALE/LE ratio was descending along with ageing in both cognitive impairment group and normal cognitivegroup , and the speed of reduction was much faster in the cognitive impairment group, especially in suburban female population over 80 years old had the lowest ALE/LE ratio. Conclusion Cognitive impairment remarkably impacted the active life expectancy on senior citizens living in Beijing,especially for the elderly.关键词
