Objectively measured physical activity and its influence on physical capacity and clinical parameters in patients with primary Sjögren's syndrome.

Abstract：

:Objective The objectives of this paper are to objectively measure habitual physical activity levels in patients with primary Sjögren's syndrome (pSS) with mild disease activity and to determine to which extent it may be associated with physical capacity and function and clinical features. Methods In this cross-sectional study, 29 women with pSS were objectively assessed for habitual physical activity levels (using accelerometry) and compared with 20 healthy women (CTRL) frequency-matched for physical activity levels, age, body mass index, and body fat percentage with regard to physical capacity and function, fatigue, depression, pain, and health-related quality of life. Results pSS showed 8.5 min/day of moderate-to-vigorous physical activity (MVPA) when only MVPA accumulated in bouts ≥ 10 min was considered; when considering total MVPA (including bouts < 10 min), average levels were 26.3 min/day, with 62% of pSS patients achieving the recommendation (≥ 21.4 min/day). Moreover, pSS showed lower VO2peak, lower muscle strength and function, higher fatigue, and poorer health-related quality of life when compared with CTRL ( p < 0.05). These differences (except for aerobic capacity) were sustained even when only individuals achieving the minimum of 21.4 min/day of total MVPA in both groups were compared. Finally, MVPA time was significantly correlated with aerobic conditioning, whereas total counts and sedentary time were associated with lower-body muscle strength and the bodily-pain domain of SF-36 in patients with pSS. Conclusion When compared to physical activity-matched healthy controls, pSS patients showed reduced physical capacity and function, increased fatigue and pain, and reduced health-related quality of life. Except for aerobic conditioning, these differences were sustained when only more physically active participants were compared, indicating that minimum recommended levels of physical activity for the general population may not be sufficient to counteract pSS comorbidities.
