Our aim is to investigate the links between duration and intensity of exercise and the nutritional status in terms of body composition in acute anorexia nervosa (AN) patients.
One hundred ninety-one hospitalized women suffering from AN were included. Exercise duration and intensity were assessed using a semistructured questionnaire. Body composition was measured using bioelectrical impedance. Linear multiple regression analyses were carried out using body mass index, fat-free mass index, and fat mass index as dependent variables and including systematically exercise duration, exercise intensity, and other confounding variables described in the literature that were significantly associated with each dependent variable in univariate analysis.
A lower BMI was linked to lower exercise intensity, AN restrictive type, and presence of amenorrhea. A lower FFMI was linked to lower exercise intensity, older age, AN restrictive type, and premenarchal AN. Duration of exercise was not linked to the nutritional status.
Exercising at higher intensity in AN is associated with a better nutritional status, thus, a better resistance to starvation. The impact of therapeutic physical activity sessions, adapted in terms of exercise intensity and patient's clinical status, should be evaluated during nutrition rehabilitation.
本研究旨在探讨急性神经性厌食症（AN）患者的运动时间和强度与身体成分营养状况之间的关系。
共纳入 191 例住院的 AN 女性患者。采用半结构式问卷评估运动时间和强度，使用生物电阻抗法测量身体成分。以体质指数、去脂体重指数和体脂指数为因变量，采用线性多元回归分析，系统纳入文献中与每个因变量在单因素分析中显著相关的运动时间、运动强度和其他混杂变量。
BMI 较低与运动强度较低、AN 限制型和闭经有关。FFMI 较低与运动强度较低、年龄较大、AN 限制型和初潮前 AN 有关。运动时间与营养状况无关。
在 AN 中进行高强度运动与更好的营养状况相关，从而对饥饿有更好的抵抗力。在营养康复期间，应评估针对运动强度和患者临床状况进行调整的治疗性体育活动课程的影响。
