Nutrition is a major modifiable factor that affects bone health. Dietary potassium may act as an alkaline source by neutralizing the acid load and reducing calcium loss from bone.We aimed to evaluate the association between dietary potassium intake and bone mineral density (BMD) in the Korean population. We analyzed data from the Korean National Health and Nutrition Examination Survey (KNHANES) A total of 3135 men aged >50 years and 4052 postmenopaus...

Low body mass index (BMI) or body weight is a well-known risk factor for osteoporosis and fragility fractures. However, the relative contribution of lean mass and fat mass on bone health, i.e. fragility fractures is inconclusive.We elucidated the relative contribution of lean and fat mass on fracture risk by group analysis in Korean men and women. This was an ongoing prospective community-dwelling cohort study at Ansung in Korea, begun in 2001. We includ...

Farnesoid X receptor (FXR) is a member of the nuclear receptor superfamily, which functions as bile acid sensor controlling the bile acid homeostasis. We have investigated the role of FXR in regulating bone metabolism in vivo. We have identified expression of FXR in calvaria and bone marrow cells, which was gradually increased during osteoblastic differentiation in vitro. Deletion of FXR in vivo has resulted in significant reduction in bone mineral density by...

Background: Aromatase inhibitors (AIs) increase the risk of fracture in patients with breast cancer. Therefore, we aimed to evaluate the long-term effects of AIs on bone health in postmenopausal women with primary breast cancer.Patients and methods: We performed a retrospective longitudinal observational study in patients with breast cancer who were treated by AIs for ≧3 years (baseline T-score >–2.5). Patients with previous anti-osteoporosis...
