Cases without matched controls or serum sodium (Na(+)) data or with Na(+) with a same-day blood glucose greater than 200 mg/dL were excluded.Abstract: MAIN OUTCOME MEASURES: Incidence of diagnosis of osteoporosis and fragility fractures of the upper or lower extremity, pelvis, and vertebrae were the outcome measures.Abstract: RESULTS: Multivariate conditional logistic regression models demonstrated that hyponatremia was associated with osteoporosis and/or fragility fractures, including chronic [osteoporosis: odds ratio (OR) 3.97, 95% confidence interval (CI) 3.59-4.39; fracture: OR 4.61, 95% CI 4.15-5.11], recent (osteoporosis: OR 3.06, 95% CI 2.81-3.33; fracture: OR 3.05, 95% CI 2.83-3.29), and combined chronic and recent hyponatremia (osteoporosis: OR 12.09, 95% CI 9.34-15.66; fracture: OR 11.21, 95% CI 8.81-14.26). Odds of osteoporosis or fragility fracture increased incrementally with categorical decrease in median serum Na(+).Abstract: CONCLUSIONS: These analyses support the hypothesis that hyponatremia is a risk factor for osteoporosis and fracture. Additional studies are required to evaluate whether correction of hyponatremia will improve patient outcomes.
