中国老年人口认知障碍对功能能力的影响
The impact of cognitive impairment on functional limitations among elderly population in China
摘要
Abstract
Objective To examine the impact of cognitive impairment on functional limitations and the role of socioeconomic status(SES)and healthy lifestyles in moderating this relationship,and to provide references for improving the care system for elderly population.Methods This study used the data from the Chinese Longitudinal Healthy Longevity Survey(CLHLS)from 2002 to 2018,with ability of activities of daily living(ADL)and instrumental activities of daily living(IADL)selected as the dependent variables.Random effect logistic models were used to analyze the influence of cognitive impairment on functional limitations in different birth cohorts and the moderating roles of SES and healthy lifestyles.Results A total of 61 115 survey data were obtained from 53 278 respondents,of whom 14.18%had cognitive impairment,21.41%had ADL limitations,and 62.35%had IADL limitations.Cognitive impairment increased higher risk of ADL limitations in the later-born birth cohort(1931-1949)(OR=3.39,95%CI:2.56～4.50)than in the early-born birth cohort(1912-1930,OR=1.45,95%CI:1.26～1.66).All differences were statistically significant(P＜0.001).SES and healthy lifestyles played moderating roles in the relationship between cognitive impairment and ADL limitations(1912-1930,OR=1.38,95%CI:1.19～1.60;1931-1949,OR=2.90,95%CI:2.10～3.99).Conclusions Cognitive impairment increases the risk of functional limitations.Older adults with cognitive impairment in later-born cohorts might be more likely to experience functional limitations and have a greater need for related care services.Social and economic development and lifestyle interventions can contribute to functional limitation prevention and control.关键词
