BACKGROUND: Sensory impairment, including hearing and vision impairment, are prevalent in older adults and may significantly contribute to cognitive frailty. However, the longitudinal association between sensory impairment and cognitive frailty has not been fully explored. The aim of our study was to examine such associations in four nationally representative cohorts to inform strategies for preventing cognitive frailty and promoting healthy aging. METHODS: Data were pooled from four large, longitudinal cohorts: the Health and Retirement Study (HRS), the Chinese Longitudinal Healthy Longevity Survey (CLHLS), the Survey of Health, Ageing and Retirement in Europe (SHARE), and the English Longitudinal Study of Ageing (ELSA). The analysis included 37,076 older adults from these cohorts, with comparable measures of sensory impairment and cognitive frailty across studies. Sensory impairments were assessed via self-reported hearing impairment and vision impairment. The outcome was the incidence of cognitive frailty, assessed using self-reported cognitive function and frailty indicators. Cox regression models were used to evaluate the association between hearing impairments, vision impairments and dual sensory impairment with cognitive frailty risk, adjusting for potential confounders. RESULTS: The cohort had a mean (SD) age of 74.60 (6.61) years for HRS (41.41% male), 81.87 (10.50) years for CLHLS (48.10% male), 72.99 (6.12) years for SHARE (44.27% male), and 73.03 (6.22) years for ...
