Lower Fatigue in Fit and Positive Women with Fibromyalgia: The al-Ándalus Project

Abstract Objective To analyze 1) the independent association of physical fitness, positive affect, and negative affect with the different dimensions of fatigue (general fatigue, physical fatigue, reduced activity, reduced motivation, and mental fatigue) and 2) whether the interactions of physical fi...

Description
Summary:Abstract Objective To analyze 1) the independent association of physical fitness, positive affect, and negative affect with the different dimensions of fatigue (general fatigue, physical fatigue, reduced activity, reduced motivation, and mental fatigue) and 2) whether the interactions of physical fitness, positive affect, and negative affect were associated with fatigue over and above the independent association. Design Cross-sectional study in 420 women with fibromyalgia. Setting Fibromyalgia associations from southern Spain. Methods Physical fitness was measured by performance-based tests, and questionnaires were used to measure positive affect, negative affect, and different dimensions of fatigue (general fatigue, physical fatigue, reduced activity, reduced motivation, and mental fatigue). Age, body mass index, and current pain level were included as potential confounders in all analyses. Results Physical fitness was independently associated with general fatigue, physical fatigue, and reduced activity (all P ≤ 0.02). Positive affect was independently associated with all fatigue dimensions (all P
