Objective: The incidence of eating disorders has increased in 15–19 years old1. There is growing concern as to its impact on bone health during adolescence where peak bone mass acquisition is of paramount importance. This paper describes bone size and size adjusted bone mineral content in an adolescent/young adult eating disorder population.Methods: A total of 68 patients (63 F/5 M, 90% anorexia nervosa and 10% atypical eating disorder), ...

Introduction: Insulin sensitising agents are reported to have a diverse range of effects on bone with metformin exerting positive effects and thiazolidinenediones (TZDs) exerting negative effects. 5’AMP-activated protein kinase (AMPK) plays a critical role in cellular energy homeostasis. It is widely expressed in the body and can be activated by metformin.Objective:: We investigated the role of AMPK pathway in mediating the effects of metformin on t...

Background and objective: High-resolution magnetic resonance imaging (hrMRI) can assess trabecular bone microarchitecture but the number of image slices required for reliable assessment is unclear.Methods: MRI was performed just below the growth plate of the proximal tibia from 20 healthy controls (all female; median age 21 years (range 18–35) and 10 cases (three mals: seven females; median age 19.5 years (range 16–48) with known bone abnormali...

Introduction: Pubertal suppression with gonadotrophin releasing hormone (GnRH) analogue is introduced after onset of puberty in adolescents with gender dysphoria (GD). As puberty is a critical period for bone accrual and changes in body composition, alterations in body composition and bone mass may be observed during treatment.Methods: Thirty-eight adolescents (32/38 assigned females at birth) with GD had dual energy X-ray absorptiometry (DXA) prior to s...
