Correlates of sedentary behavior in people with fibromyalgia: A systematic review

Abstract

Introduction: Understanding the correlates of sedentary behavior (SB) is important in the development of interventions which reduce and interrupt SB in people with fibromyalgia (PwF). This systematic review aimed to investigate the correlates of SB in PwF using the socio-ecological model.

Methods: Three databases (Embase, CINAHL and PubMed) were search from inception until July 21, 2022 using "sedentary" or different types of SB and "fibromyalgia" or "fibrositis" as keywords. The data collected was then analyzed using summary coding.

Results: Out of 23 SB correlates retrieved from 7 reports (n = 1698), no correlates were consistently reported (ie, reported in 4 or more studies). Higher pain intensity was the most commonly reported barrier for reducing/interrupting SB (reported in 3 reports). Other reported barriers to reducing/interrupting SB were experiencing physical and mental fatigue, a more severe disease impact, and a lack of motivation to be physically active (all reported in 1 study). A better experienced social and physical functioning and more vitality were facilitators for reducing/interrupting SB (all reported in 1 study). To date, in PwF no correlates of SB at the interpersonal, environmental and policy levels have been explored.

Conclusion: Research on correlates of SB in PwF is still in its infancy. The current preliminary evidence suggests that clinicians should consider physical and mental barriers when aiming to reduce or interrupt SB in PwF. Further research on modifiable correlates at all levels of the socio-ecological model is required to inform future trials aiming to modify SB in this vulnerable population.
