- Study examines the relationship between a frailty index (FI) and fall risk in middle-aged and older adults across three cohorts: CHARLS (China), ELSA (England), and HRS (US).
- A significant positive association was found between frailty scores and fall risk after adjustments, with odds ratios of 1.45 (CHARLS), 1.51 (ELSA), and 1.86 (HRS) per unit increase in FI.
- Nonlinear dose-response relationship and significant sex interaction were identified, showing a stronger association in men.
- The frailty index is validated as a practical screening tool for fall risk, with variations observed across different countries and sexes.
- Findings support targeted interventions using FI to promote healthy aging in diverse populations.
