Abstract：Objective To identify the multidimensional factors influencing balance dysfunction in middle-aged and older adults,pro-viding evidence-based support for the precise identification of high-risk individuals and the formulation of fall prevention strategies.
Methods Drawing upon the 2015 follow-up data from the China Health and Retirement Longitudinal Study(CHARLS),participants aged≥45 years were selected.Information on demographic characteristics,lifestyle habits,and health status was collected.Balance function was assessed using the full-tandem stance test.Logistic regression models were employed to analyze influencing factors and their correlation with Five Times Sit to Stand Test(FTSST)time.
Results Female(OR=1.958,95%CI:1.706 to 2.247),age(OR=1.035,95%CI:1.030 to 1.040),depressive state(OR=1.151,95%CI:1.050 to 1.262),hypertension(OR=1.115,95%CI:1.015 to 1.225),diabetes(OR=1.587,95%CI:1.390 to 1.813),history of stroke(OR=1.582,95%CI 1.289 to 1.942),sarcopenia(OR=1.273,95%CI 1.080 to 1.500)and impaired activity daily living(OR=1.306,95%CI 1.142 to 1.493)were risk factors for balance function,while being able to complete FTSST(OR=0.411,95%CI 0.341 to 0.496)and having a high cognitive level(OR=0.974,95%CI 0.965 to 0.983)were protective factors for balance function.Among those able to complete the FTSST,longer FTSST completion time increased the risk of balance impairment after adjusting for confounding factors(Q2:OR=1.287,95%CI 1.116 to 1.485;Q3:OR=1.517,95%CI 1.321 to 1.745;Q4:OR=1.857,95%CI 1.615 to 2.137).
Conclusion Balance function in middle-aged and older adults is influenced by multiple factors,with FTSST perfor-mance showing a significant negative correlation with balance impairment.
