【摘要】 目的 本研究旨在探索农村老年人的抑郁症状和运动认知风险综合征(MCR)及其子成分之间的相关性，以期为制定农村情境下MCR的预防策略提供依据。方法 通过便利抽样，于2022年7—8月在安徽省霍山县和临泉县农村地区抽取623名老年人开展横断面研究。抑郁症状采用患者健康自评量表(PHQ-9)评估，同时存在主观认知下降和步态缓慢的研究对象被判定为患有MCR。分别采用二元和有序logistic回归模型分析抑郁状况与MCR及子成分之间的相关性。结果 PHQ-9得分每增加1个单位，主观认知下降(OR=1.081,95%CI:1.034～1.129)和MCR(OR=1.086,95%CI:1.033～1.141)的风险显著增加。抑郁程度的增加与步态缓慢(OR=1.533,95%CI:1.042～2.254)、主观认知下降(OR=1.797,95%CI:1.163～2.776)以及MCR(OR=1.965,95%CI:1.165～3.316)的风险升高有关。结论 安徽省农村老年人抑郁症状与MCR及其子成分有相关性，应重视农村老年人的抑郁症状管理，早期预防MCR以延缓其病情进展为痴呆症，降低未来痴呆症的疾病负担。更多还原

【Abstract】 Objective The purpose of this study was to explore the correlation between depressive symptoms and motoric cognitive risk syndrome(MCR) and its sub-components in rural elderly, in order to provide evidence for the development of MCR prevention strategies in rural settings. Methods A cross-sectional study was conducted in rural areas of Huoshan County and Linquan County, Anhui Province, from July to August 2022, enrolling 623 elderly people through convenience sampling. Depressive symptoms were assessed by patient health questionnaire-9(PHQ-9), and MCR syndrome was defined as the presence of slow gait speed and subjective cognitive complaints. Binary and ordered logistic regression models were used to analyze the associations between depression status and MCR and its sub-components. Results Every 1-unit PHQ-9 score increase was significantly associated with a higher risk of subjective cognitive decline(OR=1.081, 95% CI: 1.034-1.129) and MCR(OR=1.086, 95% CI: 1.033-1.141). Having depressive symptoms was significantly associated with a higher risk of slow gait(OR=1.533, 95% CI: 1.042-2.254) and subjective cognitive decline(OR=1.797, 95% CI: 1.163-2.776), and MCR(OR=1.965, 95% CI: 1.165-3.316). Conclusion Depressive symptoms are associated with MCR and its sub-components in rural elderly residents in Anhui. Attention should be paid to the management of depressive symptoms in rural elderly, and the early prevention of MCR should be actively carried out in rural elderly to delay the progression to dementia and reduce the disease burden of dementia in the future.更多还原
