Article
Objective Understanding how symptoms cluster after premenopausal risk-reducing salpingo-oophorectomy (RRSO) can inform patient expectations but information is lacking. We aimed to identify symptom profiles after RRSO, changes over time, and the effect of hormone therapy (HT). Method Participants were premenopausal women from a longitudinal control...

Article
Background Women with lower body mass index (BMI) have a higher risk of surgically confirmed endometriosis but this finding runs counterintuitive to the oestrogen-dependent theory for the disease. Increasingly, endometriosis is diagnosed via non-surgical methods. We examined BMI at age 18–23 years, and changes in BMI, and the risk of endometriosis...

This study evaluated mediators of fracture risk in postmenopausal women with type 1 (T1D) and type 2 diabetes (T2D), over a 15-year follow-up period. This study provides evidence that the increased fracture risk in women with T1D or T2D is partially explained by falls. Furthermore, a shorter reproductive lifespan in women with T1D contributes modes...
