【摘要】 目的 构建基于健康行为改变整合理论的老年髋膝关节置换术后患者静态行为的干预方案并探讨其应用效果。方法 采用便利抽样法，将2024年9-11月于骨科门诊复诊患者随机分为对照组和干预组。干预组35例采用老年髋膝关节置换术后患者静态行为干预方案进行护理，该方案以健康行为改变整合理论为指导，通过文献回顾和2轮德尔菲专家函询构建；对照组34例采用常规护理。分别于干预后即刻、干预后2个月进行效果评价。结果 干预后即刻、干预后2个月两组患者总静态行为时间、体力活动总量、WOMAC骨关节炎指数得分、运动自我效能感比较，差异有统计学意义(均P<0.05)。两组上述项目比较的组间效应、时间效应、交互效应显著(均P<0.05)。结论 基于健康行为改变整合理论的静态行为干预方案的实施可有效改善患者的静态行为，增加体力活动总量、促进关节功能康复，提升运动自我效能感。更多还原

【Abstract】 Objective To develop a sedentary behavior intervention program for elderly patients after hip and knee arthroplasty based on the Integrated Theory of Health Behavior Change(ITHBC) and to evaluate its effectiveness in clinical practice.Methods A convenience sampling method was used to randomly assign patients who revisited the orthopedic outpatient department from September to November 2024 into a control group(n=34) and an intervention group(n=35).The intervention group received nursing care guided by the sedentary behavior intervention program developed under the ITHBC framework.The program was constructed through a literature review and two rounds of Delphi expert consultation.The control group received routine nursing care.Outcomes were evaluated immediately after the intervention and two months later.Results At both immediate post-intervention and two-month follow-up assessments, there were statistically significant differences between the two groups in total sedentary time, total physical activity, Western Ontario and McMaster Universities Osteoarthritis Index(WOMAC) score, and exercise self-efficacy(all P<0.05).Significant group effects, time effects, and interaction effects were observed for these variables(all P<0.05).Conclusion Implementation of the sedentary behavior intervention program based on the ITHBC effectively reduces sedentary behavior, increases overall physical activity, promotes joint functional recovery, and enhances exercise self-efficacy among elderly patients after hip and knee arthroplasty.更多还原
