摘要：Abstract Background: Vision impairment is common among older adults, and it may be related to frailty. However, the longitudinal relationship between visual impairment and frailty is still unclear. Methods: We used data from Round 1 to Round 5 from the National Health and Aging Trend Study. Two samples were community-dwelling older adults, sample 1 (without visual impairment) was classifed according to whether they have pre-frailty/frailty at R1 (N=3013) and sample 2 (without pre-frailty/frailty) was classifed according to whether they have visual impairment at R1 (N=1422), respectively. Frailty was measured using fve criteria: experiencing exhaustion, unintentional weight loss, low physical activity, slow gait, and weak grip strength. Visual impairment was assessed by asking participants if they had any visual impairment. Generalized estimating equation models were used to examine the concurrent and lagged association between visual impairment and frailty. Results: The participants were on average 76±7 years old, female (59%), non-Hispanic white (74%) with less than bachelor educated (73%), and 44% were pre-frail/frail in the older adults without visual impairment. Approximately 5% of participants had visual impairment at R1, and they tended to be female and non-Hispanic White in the older adults without frailty. The concurrent (OR, 95% CI=1.55, 1.17-2.02) and lagged (OR, 95% CI=1.79, 1.25-2.59) associations between frailty and visual impairment were signifcantly after controlling the covariates. Similarly, the concurrent (OR, 95% CI=1.63, 1.32-2.04) and lagged (OR, 95% CI=1.49, 1.20-1.87) associations between visual impairment and frailty were also signifcant. Conclusions: Overall, this study provides evidence for a longitudinal, bidirectional association between self-reported visual impairment and frailty. Future intervention programs to delay frailty progression should include strategies that may reduce the incidence of visual impairment. Keywords: Visual impairment, Frailty, Risk facto
