Motoric cognitive risk syndrome increases the risk of hospitalization in the elderly

Objective To explore the epidemiological characteristics of motoric cognitive risk syndrome (MCR) in Chinese elderly and its relationship with hospitalization. Methods Data were collected from a subcohort of the rugao longevity and aging study. Subjective memory complaints were assessed by the geriatric depression scale (GDS-15), and slow gait was assessed by the time up and go test (TUGT). MCR was determined by the presence of both. The incidence of hospitalization was recorded from the baseline survey in 2014 to the second 3-year follow-up in 2017, and the incidence of MCR in the hospitalized and non-hospitalized groups was compared to analyze the association between MCR and hospitalization. Results In this study, 1 076 subjects were enrolled, with an average age of 75.0±3.8 years old; The prevalence of MCR was 3.3%. During the 3-year follow-up period, 61.1% of the MCR group had records of hospitalization, while only 41.9% of the non-MCR group had the record of hospitalization (P＜0.05). The hospitalized gro
