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.
Cross-sectional study in 420 women with fibromyalgia.
Fibromyalgia associations from southern Spain.
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.
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 < 0.001). Negative affect was independently associated with general fatigue, physical fatigue, reduced motivation, and mental fatigue (all P ≤ 0.04). The interaction of overall physical fitness and positive affect was related to general fatigue and physical fatigue (all P ≤ 0.02). Women with fibromyalgia with higher levels of overall physical fitness and positive affect showed the lowest general fatigue and physical fatigue.
In women with fibromyalgia, positive affect was independently and consistently associated with all dimensions of fatigue. The combination of higher levels of overall physical fitness and positive affect might serve as a buffer against general and physical fatigue in women with fibromyalgia.
1）分析体能、积极情绪和消极情绪与疲劳不同维度（一般疲劳、身体疲劳、活动减少、动力下降和精神疲劳）之间的独立关联；2）分析体能、积极情绪和消极情绪的相互作用是否在独立关联之外还与疲劳有关。
对420名纤维肌痛女性进行横断面研究。
西班牙南部的纤维肌痛协会。
通过基于表现的测试来测量体能，使用问卷来测量积极情绪、消极情绪以及疲劳的不同维度（一般疲劳、身体疲劳、活动减少、动力下降和精神疲劳）。在所有分析中纳入年龄、体重指数和当前疼痛水平作为潜在混杂因素。
体能与一般疲劳、身体疲劳和活动减少独立相关（所有P≤0.02）。积极情绪与所有疲劳维度独立相关（所有P<0.001）。消极情绪与一般疲劳、身体疲劳、动力下降和精神疲劳独立相关（所有P≤0.04）。整体体能和积极情绪的相互作用与一般疲劳和身体疲劳有关（所有P≤0.02）。体能和积极情绪水平较高的纤维肌痛女性表现出最低的一般疲劳和身体疲劳。
在纤维肌痛女性中，积极情绪与疲劳的所有维度独立且始终相关。较高水平的整体体能和积极情绪相结合可能对纤维肌痛女性的一般和身体疲劳起到缓冲作用。
