Correlation of intrinsic capacity decline with falls in the elderly / 中华老年医学杂志

ABSTRACT

Objective:To investigate the correlation between decline of intrinsic capacity and falls in the elderly, in order to provide a new method and basis for fall risk assessment.Methods:A total of 125 elderly inpatients were selected between March 2019 and December 2019 for the survey.The intrinsic capacity of elderly inpatients was evaluated, and the history of falls in the past year were obtained through interviewing.The impact of intrinsic capacity on the risk of falls was analyzed by using logistics regression analysis.Results:Of 125 elderly patients, 37 had experienced falls in the past year, with an incidence of 29.6%(37/125). A decline of intrinsic capacity in varying degrees was found in 92.0%(115/125)of elderly patients and the average score of decline was 2.2(1.0, 3.0). The more intrinsic capacity decreased, the greater the risk of falls( OR=2.425, 95% CI 1.132-4.848, P=0.016). After taking demographics into consideration, age( OR=1.786, 95% CI 1.034-2.023)and decline of intrinsic capacity( OR=2.425, 95% CI 1.132-4.848)were independent risk factors for falls. Conclusions:Decline of intrinsic capacity is closely related to the occurrence of falls.The five-dimension framework of intrinsic capacity provides new ideas and directions for predicting the risk of falls.
