Excessive physical activity is one of the most paradoxical features of anorexia nervosa (AN). However, there is individual variation in the degree of physical activity found in AN-patients. As a result, marked differences in energy expenditure may be expected. Furthermore, exercise has a positive impact on a variety of psychological disorders and the psychopathology may be different in AN displaying high exercise levels versus AN displaying low exercise levels. We analyzed the energy metabolism and psychological data in low-level exercise and high-level exercise AN-patients compared with healthy, age matched controls.
REE was decreased in AN-patients compared with controls but not when adjusted for body surface area or lean body mass. No differences in TDEE between AN- patients and controls were observed. Subgroup analyses showed that the percentage of high-level AN- exercisers was higher compared with controls. This subgroup had increased resting EE, total daily EE and scored higher on depression and the EDI-item "Drive for thinness" compared with low-level AN-exercisers.
We identified a significant subgroup of high-level AN-exercisers (66%) with consecutive increased energy requirements. An easy way for clinicians to assess the amount of exercise before and in the course of treatment is a single question in the established Eating Disorder Inventory-SC (EDI-SC).
过度的体力活动是神经性厌食症（AN）最矛盾的特征之一。然而，在 AN 患者中，体力活动的程度存在个体差异。因此，预计能量消耗会有明显的差异。此外，运动对各种心理障碍有积极影响，而表现出高运动量的 AN 和表现出低运动量的 AN 的精神病理学可能不同。我们分析了低水平运动和高水平运动 AN 患者与健康、年龄匹配的对照组的能量代谢和心理数据。
与对照组相比，AN 患者的静息能量消耗（REE）降低，但与体表面积或瘦体重校正后并无差异。AN 患者与对照组之间的总能量消耗（TDEE）无差异。亚组分析显示，与对照组相比，高水平 AN 运动者的比例更高。与低水平 AN 运动者相比，这一亚组的静息能量消耗、总日能量消耗增加，且抑郁和 EDIN 量表“对消瘦的渴望”得分更高。
我们发现了一个显著的高水平 AN 运动者亚组（66%），其能量需求连续增加。临床医生在治疗前和治疗过程中评估运动量的一种简单方法是在既定的饮食失调量表-SC（EDI-SC）中询问一个问题。
