Abstract
Introduction: Motoric cognitive risk syndrome (MCR) is a screening syndrome that has been associated with increased dementia risk in prior studies. This study aimed to investigate the prevalence, associated factors, and adverse outcomes of MCR among community-dwelling older adults in China.
Methods: A cross-sectional analysis was conducted among 5,242 China Health and Retirement Longitudinal Study (CHARLS) participants aged ≥60 years to examine factors associated with prevalent MCR, and prospective outcomes were evaluated over a 3-year follow-up. The Boruta algorithm was used for feature selection. Multivariate logistic regression analysis was employed to assess associations, while XGBoost was applied as a complementary baseline classification approach to rank feature importance for distinguishing prevalent MCR.
Results: The prevalence of MCR was 12.9% among the study population, with higher rates in unmarried, illiterate, and older participants. Physical performance measures emerged as the strongest associated factors, with five-time sit-to-stand test (odds ratio [OR] = 1.05, 95% confidence interval [95% CI]: 1.03-1.07), handgrip strength (OR = 0.98, 95% CI: 0.97-0.99), and mobility score (OR = 1.12, 95% CI: 1.04-1.19) showing significant associations. Higher education level (OR = 0.67, 95% CI: 0.51-0.89) and social activity participation (OR = 0.69, 95% CI: 0.58-0.82) were inversely associated with prevalent MCR, while stroke (OR = 2.18, 95% CI: 1.43-3.24), visual impairment (OR = 1.40, 95% CI: 1.08-1.84), and poor self-reported health status (OR = 1.50, 95% CI: 1.13-2.00) were associated with higher odds of prevalent MCR. MCR was prospectively associated with activities of daily living disability (adjusted OR = 1.40, 95% CI: 1.12-1.73) but not hospitalization (adjusted OR = 1.08, 95% CI: 0.87-1.34).
Conclusion: These findings underscore the importance of incorporating physical performance measures and social factors in MCR screening protocols and may inform screening and risk stratification in aging populations.
期刊介绍:
In view of the ever-increasing fraction of elderly people, understanding the mechanisms of aging and age-related diseases has become a matter of urgent necessity. ''Gerontology'', the oldest journal in the field, responds to this need by drawing topical contributions from multiple disciplines to support the fundamental goals of extending active life and enhancing its quality. The range of papers is classified into four sections. In the Clinical Section, the aetiology, pathogenesis, prevention and treatment of agerelated diseases are discussed from a gerontological rather than a geriatric viewpoint. The Experimental Section contains up-to-date contributions from basic gerontological research. Papers dealing with behavioural development and related topics are placed in the Behavioural Science Section. Basic aspects of regeneration in different experimental biological systems as well as in the context of medical applications are dealt with in a special section that also contains information on technological advances for the elderly. Providing a primary source of high-quality papers covering all aspects of aging in humans and animals, ''Gerontology'' serves as an ideal information tool for all readers interested in the topic of aging from a broad perspective.
