本研究的目的是探讨女性类风湿性关节炎(RA)患者体力活动(PA)和身体功能(PF)指标之间的关系。我们假设PA和PF之间的关联强度是适度的，在控制了社会和生物医学特征后，这种关联将会减少。47名RA患者参与了这项研究的横断面分析(年龄58±6岁)。研究的社会和生物医学特征包括年龄、种族、疾病持续时间、婚姻和教育状况、身高、体重、合并症和疾病活动。通过自我报告健康评估问卷(HAQ)和一系列基于表现的测量来测量PF，这些测量包括自我选择的步速、5椅上升测试和单腿站立测试。通过佩戴10天的便携式活动监测器测量Pa值，并以两种方式进行表征：每日平均步数和中等PA水平时的每日能量消耗。PA和PF的测量之间的相关性是小到中等的(零级相关=.189到.479)。在控制了社会和生物医学特征后，相关性变得更小(半部分相关=0.095到0.277)，只有HAQ仍然与PA显著相关。PA测量和PF测量之间的关联部分由RA妇女的社会和生物医学特征来解释。结果表明，PF和PA的测量可能代表了不同的结构，支持了RA康复研究中测量PA的必要性。
The purpose of this study was to explore the associations between measures of physical activity (PA) and measures of physical function (PF) in women with rheumatoid arthritis (RA). We hypothesized that the strength of the associations between PA and PF would be moderate, and that after controlling for social and biomedical characteristics, the associations would decrease. Forty seven women with RA participated in the cross-sectional analysis of this study (age 58 ± 6 years). Social and biomedical characteristics explored included age, ethnicity, disease duration, marital and educational status, height, weight, comorbidity, and disease activity. PF was measured by the self-reported Health Assessment Questionnaire (HAQ) and by a battery of performance-based measures that included the self-selected gait speed, the 5-chair rise test, and the single leg stance test. PA was measured by a portable activity monitor worn for 10 days, and was characterized in 2 ways: daily average number of steps, and daily energy expenditure during moderate levels of PA. Correlations between measures of PA and PF were small to moderate (zero-order correlations= .189 to .479). After controlling for social and biomedical characteristics, the correlations became smaller (semi-partial correlations= .095 to .277), and only HAQ remained significantly associated with PA. Associations between measures of PA and measures of PF are explained, in part, by social and biomedical characteristics in women with RA. The results indicate that measures of PF and PA may represent different constructs and support the need to measure PA in rehabilitation research in RA.
