目的 探讨周期性的内在能力干预对社区轻度失能老人的应用效果评价。方法 2023年12月至2024年6月，采用随机抽样法选择重庆市某社区48例轻度失能老人为研究对象，采用掷硬币法随机将其分为试验组（n=25）和对照组（n=23）。试验组进行为期24周的周期性的内在能力干预，对照组进行社区原有的健康干预。于干预前及干预12、24周后比较两组内在能力。结果 干预前后，两组内在能力、简易躯体功能评估、简易营养评价量表及简易精神状态检查量表得分比较，时间与组别之间均存在交互作用（均P＜0.05）。干预24周后，试验组内在能力、简易躯体功能评估量表及简易营养评价量表得分均高于对照组（均P＜0.05）。结论 周期性的内在能力干预对社区轻度失能老人内在能力、运动能力及营养状态有积极影响。

Objective To evaluate the effectiveness of periodic intrinsic capacity intervention in community-dwelling older adults with mild disability.Methods From December 2023 to June 2024,48 older adults with mild disability were randomly sampled from a community in Chongqing and randomly assigned to either the experimental group (n=25) or control group (n=23) using coin toss method.The experimental group received 24-week periodic intrinsic capacity intervention,while the control group received routine community health intervention.Differences in intrinsic capacity scores were compared between groups before intervention,12 weeks,and 24 weeks post-intervention.Results Significant interaction effects between time and group were observed in intrinsic capacity,Short Physical Performance Battery (SPPB),Mini Nutritional Assessment (MNA),and Mini-Mental State Examination (MMSE) scores (all P＜0.05).At 24 weeks,the experimental group showed significantly higher scores in intrinsic capacity,SPPB,and MNA compared to the control group (all P＜0.05).Conclusions Periodic intrinsic capacity intervention demonstrates positive effects on intrinsic capacity,physical function,and nutritional status in community-dwelling older adults with mild disability.
