The purposes of this study were to describe the prevalence of fatigue, examine the association between fatigue and doctor visits, and identify correlates of fatigue in rheumatoid arthritis (RA). On average, a high degree of fatigue was reported to occur every day, to remain constant during the course of a week, and to most often affect walking and household chores. When controlling for disease severity and insurance coverage, respondents who reported more fatigue made more visits to the rheumatologist than those reporting less fatigue. A regression model with fatigue as the dependent variable revealed that the following variables explained a significant amount of variance: pain rating, functional status, sleep quality, female gender, comorbid conditions, and duration of disease.
本研究的目的是描述疲劳的患病率，检查疲劳与就医之间的关联，并确定类风湿关节炎（RA）患者疲劳的相关因素。平均而言，据报告每天都会出现高度疲劳，且在一周内保持不变，最常影响行走和家务劳动。在控制疾病严重程度和保险覆盖范围后，报告疲劳程度较高的受访者比报告疲劳程度较低的受访者看风湿病专家的次数更多。以疲劳为因变量的回归模型显示，以下变量解释了相当大比例的方差：疼痛评分、功能状态、睡眠质量、女性性别、合并症和病程。
