Analysis of intrinsic capacity and influencing factors in community-dwelling elderly people / 中华老年医学杂志

ABSTRACT

Objective:To investigate the level of intrinsic capacity in community-dwelling elderly people and the influencing factors, in order to provide supporting evidence for the improvement of intrinsic capacity, formulation of management strategies, and promotion of quality of life for the elderly.Methods:A cross-sectional survey was carried out from November 2020 to December 2020 with 236 community-dwelling elderly people in Beijing, who were recruited through a convenience sampling method.The investigation used questionnaires for general data and influencing factors for intrinsic capacity, and the World Health Organization intrinsic capacity questionnaire.Multivariate logistic regression was used to analyze the influencing factors for intrinsic capacity of the elderly.Results:Among 236 community-dwelling elderly people, 132(55.9%)had fair intrinsic capacity(≥4 points)and 104(44.1%)had poor intrinsic capacity(<4 points), with an average score of(3.39±0.95). Multiple Logistic regression analysis results showed that sex( OR=2.005, 95% CI 1.093-3.676, P=0.025), age( OR=1.727, 95% CI 1.043-2.860, P=0.034), social participation( OR=0.321, 95% CI 0.170-0.604, P<0.001), entertainment( OR=2.073, 95% CI 1.079-3.985, P=0.029), exercise( OR=2.975, 95% CI 1.761-3.784, P=0.039), sleep( OR=0.508, 95% CI 0.265-0.973, P=0.041), and emotions( OR=0.436, 95% CI 0.196-0.970, P=0.042)were influencing factors for intrinsic capacity of community-dwelling elderly people. Conclusions:The intrinsic capacity of community-dwelling elderly people is in the middle range.Sex, age, social participation, entertainment, exercise, sleep, and emotions can affect intrinsic capacity.Therefore, intervention strategies based on influencing factors and improvement of lifestyles can help maintain good intrinsic capacity and reduce adverse effects of major health events.
