Abstract:
ObjectiveTo identify the multidimensional factors influencing balance dysfunction in middle-aged and older adults, providing evidence-based support for the precise identification of high-risk individuals and the formulation of fall prevention strategies. MethodsDrawing 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. ResultsFemale (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). ConclusionBalance function in middle-aged and older adults is influenced by multiple factors, with FTSST performance showing a significant negative correlation with balance impairment.
