Anorexia nervosa (AN), a psychiatric disorder predominantly affecting young women, is characterized by self-imposed, chronic nutritional deprivation and distorted body image. AN is associated with a number of medical comorbidities including low bone mass. The low bone mass in AN is due to an uncoupling of bone formation and bone resorption, which is the result of hormonal adaptations aimed at decreasing energy expenditure during periods of low energy intake. Importantly, the low bone mass in AN is associated with a significant risk of fractures and therefore treatments to prevent bone loss are critical. In this review, we discuss the hormonal determinants of low bone mass in AN and treatments that have been investigated in this population.
神经性厌食症(AN)是一种主要影响年轻女性的精神疾病,其特征是自我施加的、慢性的营养剥夺和扭曲的身体形象。AN 与许多医学合并症有关,包括低骨量。AN 中的低骨量是由于骨形成和骨吸收的解偶联所致,这是为了在能量摄入低的时期减少能量消耗而发生的激素适应的结果。重要的是,AN 中的低骨量与骨折的风险显著相关,因此预防骨质流失的治疗至关重要。在这篇综述中,我们讨论了 AN 中低骨量的激素决定因素以及在该人群中研究过的治疗方法。
