Bioimpedance analysis was used for weekly assessments of body fat content in 20 adolescents with anorexia nervosa (mean BMI 15.6 kg/m2; mean age, 14 years 5 months) until the desired weight had been achieved, but for a minimum of 12 weeks. As expected, body fat content increased with BMI. Total body fat increased faster than fat-free body mass, the relative increase being 66%, vs 11% for fat-free body mass. However, an expected association between an increase in the percentage of body fat and resumption of menstruation did not occur. As a noninvasive, repeatable procedure including the assessment intraabdominal fatty tissue, determination of total body fat by bioimpedance analysis is suitable for use in longitudinal studies of anorexia nervosa.
对20名神经性厌食青少年（平均体重指数15.6kg/m²；平均年龄14岁5个月）进行生物电阻抗分析，每周评估其体脂含量，直至达到理想体重，但至少持续12周。正如预期的那样，体脂含量随体重指数增加。总体脂肪增加速度快于去脂体重，相对增加率分别为66%和11%。然而，体脂百分比增加与月经恢复之间并未出现预期的关联。作为一种包括评估腹部脂肪组织在内的非侵入性、可重复的程序，通过生物电阻抗分析测定总体脂肪适用于神经性厌食症纵向研究。
