To identify the effect of duration of weight-bearing exercise and team sports participation on bone mineral density (BMD) and body composition among adolescents with anorexia nervosa (AN).
We retrospectively reviewed electronic medical records of all patients 9-20 years old with a DSM-5 diagnosis of AN evaluated by the Stanford Eating Disorders Program (1997-2011) who underwent dual-energy X-ray absorptiometry.
A total of 188 adolescents with AN were included (178 females and 10 males). Using multivariate linear regression, duration of weight-bearing exercise (B = 0.15, p = 0.005) and participation in team sports (B = 0.53, p = 0.001) were associated with higher BMD at the hip and team sports (B = 0.39, p = 0.006) were associated with higher whole body BMC, controlling for covariates. Participation in team sports (B = - 1.06, p = 0.007) was associated with greater deficits in FMI Z-score. LBMI Z-score was positively associated with duration of weight-bearing exercise (B = 0.10, p = 0.018) and may explain the relationship between exercise and bone outcomes.
Duration of weight-bearing exercise and team sports participation may be protective of BMD at the hip and whole body BMC, while participation in team sports was associated with greater FMI deficits among adolescents with AN.

确定负重运动和团队运动参与时间对神经性厌食症(AN)青少年的骨密度(BMD)和身体成分的影响。
我们回顾性地分析了斯坦福饮食失调项目(1997-2011 年)评估的所有 9-20 岁符合 DSM-5 诊断标准的 AN 患者的电子病历,这些患者接受了双能 X 射线吸收法检查。
共纳入 188 名 AN 青少年(178 名女性,10 名男性)。使用多元线性回归分析,负重运动的持续时间(B=0.15,p=0.005)和团队运动的参与(B=0.53,p=0.001)与髋部 BMD 较高相关,而团队运动(B=0.39,p=0.006)与全身 BMC 较高相关,控制了协变量。团队运动的参与(B=-1.06,p=0.007)与 FMI Z 评分的更大缺陷相关。LBMI Z 评分与负重运动的持续时间呈正相关(B=0.10,p=0.018),可能解释了运动与骨骼结果之间的关系。
负重运动的持续时间和团队运动的参与可能对髋部和全身 BMC 的 BMD 有保护作用,而团队运动的参与与 AN 青少年 FMI 缺陷更大有关。
