Relationship between grip strength change trajectory and cognitive function among community-dwelling elderly people
摘要
Abstract
Objective:To explore grip strength change trajectory of community-dwelling elderly people and its relationship with cognitive function.Methods:Based on the grip strength and cognitive function data of community-dwelling elderly people from the China Health and Retirement Longitudinal Study(CHARLS)in 2011,2013,and 2015,group-based trajectory model(GBTM)was used to establish the grip strength change trajectory of community-dwelling elderly people.Multiple linear regression was used to analyze the relationship between grip strength trajectory and cognitive function.Results:A total of 1 245 community-dwelling elderly people were included.GBTM analysis results showed that there were four grip strength trajectories among community-dwelling elderly people:extremely low level group,low level group,medium level group,and high level group.Multiple linear regression analysis results showed that after adjusting for confounding factors,compared to the extremely low level group,the grip strength of elderly people in the low level group,medium level group,and high level group were positively correlated with their cognitive function;The area under the receiver operating characteristic curve for predicting cognitive function using grip strength trajectory was 0.622(95%CI 0.587-0.657).Conclusions:The grip strength trajectory of community-dwelling elderly people could be divided into four categories:extremely low level group,low level group,medium level group,and high level group,which have certain predictive value for the cognitive function of community-dwelling elderly people.Low grip strength in the elderly is a risk factor for cognitive decline.Therefore,early identification of the development trajectory of grip strength in the elderly is particularly important.关键词
