We assessed whether level of physical activity of anorexia nervosa patients could influence caloric consumption needed to gain weight during hospitalization. Seventy-three percent of patients with anorexia nervosa had higher levels of motor activity than did healthy female volunteers. Anorectics required 8301 +/- 2272 kcal (mean +/- SD) to gain 1 kg body wt. Activity levels and caloric consumption needed to gain 1 kg were significantly correlated; the most active patients needed to consume more calories to gain weight. A median split of anorectic patients by level of activity showed that the group with lower activity levels gained 1 kg every 5.1 +/- 1.2 d, whereas the group with higher activity levels gained 1 kg every 7.2 +/- 1.9 d. These data suggest that the rate of weight gain can be accelerated, and the cost of hospitalization decreased, by restricting exercise in anorectics during refeeding.
我们评估了神经性厌食症患者的身体活动水平是否会影响住院期间体重增加所需的热量消耗。73%的神经性厌食症患者的运动活动水平高于健康女性志愿者。厌食症患者体重增加1千克需要8301±2272千卡（平均值±标准差）。活动水平与体重增加1千克所需的热量消耗显著相关；活动量最大的患者体重增加需要消耗更多热量。按活动水平对厌食症患者进行中位数划分显示，活动水平较低的组每5.1±1.2天体重增加1千克，而活动水平较高的组每7.2±1.9天体重增加1千克。这些数据表明，在再喂养期间限制厌食症患者的运动，可以加快体重增加速度，并降低住院费用。
