Besides the important beneficial effects of regular physical activity on general health, some of the musculoskeletal effects of physical activity are of particular interest for older adults after total hip arthroplasty (THA). However, research on physical activity behavior of patients after THA is scarce.
The purpose of this study was to gain insight into the physical activity behavior and fulfillment of guidelines for health-enhancing physical activity of patients 1 year after THA. Design This was a prospective multicenter cohort study.
To determine level of physical activity, 653 participants (response rate=77%) completed the Short QUestionnaire to ASsess Health-enhancing physical activity (SQUASH). Comparisons were made between participants in 2 age groups (≤75 and >75 years). Determinants of physical activity behavior were assessed.
The participants were physically active a mean of 1,468 minutes per week. Most time was spent in household and leisure activities. Younger participants were physically more active than older participants. A lower body mass index was predictive of a higher level of physical activity. Participants adhered to the guidelines of health-enhancing physical activity in 67% of cases. The guidelines were met more often by younger participants, male participants, and those without problems in the lower extremities. Limitations A nonresponse analysis was not conducted; thus, there might have been a selection bias. Use of a self-administered recall questionnaire to assess physical activity behavior may have been subject to memory and recall skill limitations of the participants, and patients tend to overestimate their physical activity level.
This study gives detailed insight into the physical activity of patients 1 year after primary THA. As among the general population, a considerable number of patients were found to be insufficiently physically active.
除了有规律的体育活动对一般健康的重要有益影响外，体育活动对骨骼肌肉的一些影响对于全髋关节置换术（THA）后的老年人尤其重要。然而，关于 THA 后患者的体育活动行为的研究很少。
本研究旨在深入了解患者 THA 后 1 年的体育活动行为和满足健康促进体育活动指南的情况。设计：这是一项前瞻性多中心队列研究。
为了确定身体活动水平，653 名参与者（响应率=77%）完成了简短的健康促进身体活动问卷（SQUASH）。比较了 2 个年龄组（≤75 岁和>75 岁）的参与者。评估了身体活动行为的决定因素。
参与者平均每周进行 1468 分钟的身体活动。大部分时间用于家务和休闲活动。年轻参与者比年长参与者更活跃。较低的身体质量指数预测了更高的身体活动水平。在 67%的情况下，参与者符合健康促进身体活动的指南。年轻参与者、男性参与者和下肢无问题的参与者更符合指南。局限性：未进行非响应分析；因此，可能存在选择偏倚。使用自我管理的回忆问卷来评估身体活动行为可能受到参与者记忆和回忆技能的限制，并且患者往往会高估自己的身体活动水平。
本研究详细了解了初次 THA 后患者的身体活动情况。与一般人群一样，发现相当一部分患者身体活动不足。
