Longitudinal association between falls and motoric cognitive risk syndrome among community-dwelling older adults

The motoric cognitive risk (MCR) syndrome is a predementia syndrome associated with dementia and mortal-ity risk. This longitudinal study aimed to investigated the longitudinal association between MCR and falls in older adults, including 3,720 participants in the China Health and Retirement Longitudinal Study. A total of 482 participants (13.0%) met the MCR requirements at baseline. There were 226 incident cases of MCR (13.0%) throughout follow-up (duration: 4 years). Controlling for microsystem factors, a single fall (OR: 2.412, 95 % CI: 1.100-5.290; p < .05) was associated with incident MCR at baseline and to almost 2.0 times (HR: 2.021, 95 % CI: 1.031-3.961; p < .05) more inclined to develop MCR over time, compared to those without falls. These associa-tions remained significant when meso/ exosystem factors and macrosystem factors were included in the ana-lytic models. Falls may be useful in predicting MCR risk in the near future among Chinese older adults.(c) 2022 Elsevier Inc. All rights reserved.
