A correlation research of intrinsic capacity and fall risk in older adults based on latent class analysis/
Objective To explore latent classes of intrinsic capacity in older adults and analyze the role of different latent classes in influencing the occurrence of falls in older adults.Methods A convenience sampling method was utilized to select the older adults in a community in Beijing in November-December 2020 as the survey respondents.General Information Questionnaire and WHO Intrinsic Capacity Assessment Tool were used to collect information,and the study participants were followed up in June-July,2023.Potential classes were analyzed using Mplus 8.0 software,and logistic regression was used to analyze the effect of potential classes of intrinsic capacity on falls.Results Follow-up was completed by 243(85.6％)survey respondents,with a decrease in the follow-up intrinsic capacity score from baseline(Z=4.667,P＜0.001),and 30(12.3％)older adults had experienced falls in the last 1 year.The intrinsic capacity of the older people can be clustered into 3 potential classes,namely,the low level of perception group(69.7％),the low level of cognition and perception group(23.2％),and the medium level of cognition and low level of vitality,psychological and perception group(7.1％).Logistic regression results showed that the risk of falling in the group with the medium cognition and low vitality,psychological and perception is 5.777 times(95％CI:1.824-18.298)higher than that in the group with low perception,and the risk of falling in the group with medium cognition and low vitality,psychological and perception is 7.534 times(95％CI:1.822-31.150)higher than that in the group with low cognition and perception.Conclusion The prevalence of falls in the older adults is high;the intrinsic capacity is heterogeneous;potential classes of intrinsic capacity play different roles in the degree to which they predict the risk of falls.It is recommended to pay attention to the heterogeneity of intrinsic capacity of older adults in clinical work and to take targeted measures to prevent falls.
