神经性厌食症(AN)是一种以自我诱发饥饿为特征的精神疾病,女性终生患病率为2.2%。AN女性最常见的医学共病是骨丢失,超过85%的女性骨密度值比年龄可比平均值低一个标准差以上。AN的低骨量是由于多种激素对营养不足的适应,包括下丘脑性闭经和生长激素抵抗。重要的是,这种低骨量也与骨折风险增加7倍有关。因此,有效预防骨丢失和增加低骨量的策略至关重要。我们将回顾导致该人群骨丢失的激素适应,以及可能增加AN骨量和降低骨折风险的有前途的新疗法。
Anorexia nervosa (AN) is a psychiatric disorder characterized by self-induced starvation with a lifetime prevalence of 2.2% in women. The most common medical co-morbidity in women with AN is bone loss, with over 85% of women having bone mineral density values more than one standard deviation below an age comparable mean. The low bone mass in AN is due to multiple hormonal adaptations to under nutrition, including hypothalamic amenorrhea and growth hormone resistance. Importantly, this low bone mass is also associated with a seven-fold increased risk of fracture. Therefore, strategies to effectively prevent bone loss and increase low bone mass are critical. We will review hormonal adaptations that contribute to bone loss in this population as well as promising new therapies that may increase bone mass and reduce fracture risk in AN.
