Serum Sodium and Areal Bone Mineral Density in American Adult’s Population: A Secondary Analysis Based on the National Health and Nutrition Examination Survey

1. Abstract
1.1. Background: Osteoporosis is a bone disease characterized by decreased Bone Mineral Density (BMD) and an increased risk of fracture. Hyponatremia has been found associated with osteoporosis and fractures. The dose-response relationship between serum sodium and bone mineral density remains unclear.
