【摘要】 目的 探讨农村老年人运动认知风险综合征（motoric cognitive risk syndrome, MCR）与其参数和肌少症之间的相关性，以及行为生活方式（运动、饮酒、吸烟）在上述关系中的调节效应，为制定有针对性的干预策略和预防措施提供依据。方法 采用方便抽样，从安徽省农村地区抽取652名老年人进行调查，MCR通过主观认知下降和步速缓慢来综合评估，肌少症通过肌少症五条目量表（sarcopenia five, SARC-F）来评估。采用回归方法分析MCR及其参数与肌少症的相关性，并分析行为生活方式在其中的调节作用。结果 患有MCR的老年人SARC-F得分更高（β=0.819,P<0.05），患肌少症风险也较高（OR=1.794, P<0.05）。分层分析结果显示，行为生活方式在MCR与肌少症关系中存在显著调节作用，尤其在无运动、不饮酒和不吸烟人群中，MCR对肌少症的风险影响更为显著。结论 MCR与较高的肌少症风险相关，运动、饮酒、吸烟在上述相关性中具有一定的调节效应。更多还原

【Abstract】 Objective To investigate the associations between motoric cognitive risk syndrome(MCR) and its parameters with sarcopenia among elderly individuals in rural areas, and the moderating effect of lifestyle behaviors(physical activity, alcohol consumption, smoking) on the relationship between MCR and sarcopenia, to provide a scientific basis for developing targeted intervention strategies and preventive measures. Methods A convenience sampling method was employed, and 652 elderly participants were recruited from rural regions of Anhui Province for this study. MCR was assessed by a combination of subjective cognitive decline and slow gait, and sarcopenia was assessed by Sarcopenia Five(SARC-F). The regression method was used to analyze the correlation between MCR and its parameters and sarcopenia, and the moderating role of lifestyle behaviors in the above correlation was analyzed. Results Older adults with MCR had higher SARC-F scores(β=0.819, P<0.05), and had a higher risk of developing sarcopenia(OR=1.794, P<0.05). Stratified analysis revealed that lifestyle behaviors significantly moderated the association between MCR and sarcopenia, with the effect of MCR on sarcopenia risk being more pronounced among individuals who did not exercise, did not consume alcohol, and did not smoke. Conclusion MCR is associated with a higher risk of sarcopenia, and exercise, alcohol consumption, and smoking have a moderating effect on the above associations.更多还原
