背景患有类风湿性关节炎（RA）的个体通常久坐不动，并且具有发展共病状况的增加的风险。与RA或健康的人相比，RA女性更有可能在一生中保持积极的生活方式方面遇到挑战。由于体力活动（PA）的益处是众所周知的，因此准确测量该人群的PA非常重要。本研究的目的是：（1）表征RA女性患者使用SenseWear臂带（SWA）测量的PA，（2）确定测量时间范围，以获得RA女性患者PA和每日能量消耗（EE）的一致估计值。这是一项横断面研究。参与者穿着SWA 7天。测量每日总能量消耗（TEE）、1代谢当量（MET）以上活动时的体力活动能量消耗（PAEE）（PAEE> 1 MET）、2代谢当量以上活动时的PAEE（PAEE >= 2 MET）、3代谢当量以上活动时的PAEE（PAEE >= 3 MET）和步数。有53名妇女参加。获得了47名参与者（89%）的完整数据。SWA的每日使用率为98%（23：31小时/24小时）。TEE的平均值（SD）为2，099（340）kcal/d，PAEE >= 1 MET的平均值（SD）为1，050（331）kcal/d，PAEE >= 2 MET的平均值（SD）为642（309）kcal/d，PAEE >= 3 MET的平均值（SD）为239（178）kcal/d，步数为7，260（2，710）。组内相关系数分析和多元线性回归结果表明，可靠估计TEE需要2天; PAEE >= 1 MET、PAEE >= 2 MET和步数需要3天; PAEE >= 3 MET需要4天。局限性。样本由受过良好教育的RA女性组成，她们有轻度至中度的日常活动困难。SWA可能有助于量化RA妇女的PA，并监测旨在提高PA水平的干预措施的有效性。最大限度地减少数据收集所需的天数将减少个人的负担，并可能提高PA行为研究的依从性。
Background. Individuals with rheumatoid arthritis (RA) often are sedentary and have an increased risk of developing comorbid conditions. Women with RA are more likely to experience challenges in maintaining an active lifestyle over their life span than men with RA or people who are healthy. As the benefits of physical activity (PA) are well known, measuring PA accurately in this population is important.Objectives. The purposes of this study were: (1) to characterize PA as measured with the SenseWear Armband (SWA) in women with RA and (2) to determine the measurement time frame to obtain consistent estimates of PA and daily energy expenditure (EE) in women with RA.Design. This was a cross-sectional study.Methods. Participants wore the SWA for 7 days. Measurements of daily total energy expenditure (TEE), physical activity energy expenditure (PAEE) during activities at or above 1 metabolic equivalent (MET) level (PAEE>1MET), PAEE during activities at or above 2 METs (PAEE >= 2METs), PAEE during activities at or above 3 METs (PAEE >= 3METs), and number of steps were obtained.Results. Fifty-three women participated. Complete data were obtained for 47 participants (89%). Daily usage of the SWA was 98% of the time (23: 31 hours/24 hours). Means (SD) were 2,099 (340) kcal/d for TEE, 1,050 (331) kcal/d for PAEE >= 1MET, 642 (309) kcal/d for PAEE >= 2METs, 239 (178) kcal/d for PAEE >= 3METs, and 7,260 (2,710) for number of steps. Results of intraclass correlation coefficient analyses and multiple linear regressions indicated that 2 days were needed to reliably estimate TEE; 3 days for PAEE >= 1MET, PAEE >= 2METs, and number of steps; and 4 days for PAEE >= 3METs. Limitations. The sample was composed of well-educated women with RA who had mild to moderate difficulty performing daily activities.Conclusion. The SWA may be useful to quantify PA in women with RA and to monitor effectiveness of interventions aiming to increase PA levels. Minimizing the number of days necessary for data collection will reduce the individual's burden and may improve adherence in studies of PA behaviors.
