Study On Hypothetical Interventions Of Frailty Among Chinese Elderly

As a measure of the general health of the elderly,frailty is a hot and difficult issue in the studies about elderly health.Therefore,the G-formula hypothetical intervention model was applied to explore frailty incidence and the statistics causal effect of lifestyle on frailty in elderly Chinese subjects,aiming to address the issue of the short follow-up,small sample and limited interventions brought by field intervention studies,to provide an evidence-based guidance for lower the incidence of frailty and provide theoretical basis for further field intervention studies.The data was drawn from the China Health and Retirement Longitudinal study(CHARLS),we used the 2011-2015 follow-up survey.The subjects were 5387 elderly Chinese subjects over 60 years of age at 2011 baseline survey.The Physical Frailty Phenotype(PFP)was used to measure the status of frailty.The G-formula hypothetical intervention model was conducted to analyze and understand the incidence of frailty in different population groups by taking the frequency of social activities,smoking status and sleep time as intervention methods to carry out single factor interventions and joint interventions,and to find the best intervention and intervention program to reduce the occurrence of frailty.At the end of the follow-up in 2015,there were 506 subjects developed frailty,and the incidence was 9.39%.The incidence of frailty in those who were elderly aged(over 70 years),female,lower levels of Education,lived in western district were 15.06%,10.77%,11.03%and 9.68%separately.When only intervene one factors,taking part in social activities were most effective interventions,and club activities(RR=0.54,95%CI:0.29-0.62)could low the incident risk of frailty to the most extent,following was chess and cards activities(RR=0.88,95%CI:0.80-0.95)and interaction with friends(RR=0.97,95%CI:0.95-0.98).During the follow-up period,the frailty incidence in China was basically consistent with the average level ofprevious study at home and abroad.The incidence of frailty in those who were elderly aged(over 70 years),lower levels of education were higher than other subjects.Three kinds of social activities can reduce the incidence of frailty:club activities>chess and card activities>interaction with friends.Three kind of social activities combined hypothetical interventions were the best intervention program.Therefore,the government should formulate corresponding policies,increase the investment of funds and advocate a healthy lifestyle among the elderly.The future field intervention of frailty may consider the social activities which are physically engaging and the active interaction with others as the intervention measures in order to reduce the incidence of frailty and maintain their functional integrity.
