METHODS: Risk factors for
hyperphosphatemia included higher adjusted
calcium (OR 2.90, 95% CI 2.43-3.45), increasing
cholesterol (OR 1.003, 95% CI 1.001-1.005), female gender (OR 1.61, 95% CI 1.39-1.87) and low
hemoglobin (OR 1.52, 95% CI 1.17-1.98). Advanced age was protective (OR 0.98, 95% CI 0.977-0.987). Models that included fasting serum
glucose found lower body mass index (BMI) to be protective (OR 0.97, 95% CI 0.96-0.99) and adjusting for serum
vitamin D and
parathyroid hormone removed the association with low
hemoglobin and BMI. Risk factors for
hypophosphatemia included the following protective factors: higher
albumin (OR 0.56, 95% CI 0.35-0.93), higher BUN (OR 0.90, 95% CI 0.86, 0.95), corrected
calcium (OR 0.38, 95% CI 0.23-0.63) and female gender (OR 0.47, 95% 0.24-0.94). In men, higher fasting
glucose levels increased risk (OR 1.01, 95% CI 1.0004-1.01).
CONCLUSION:
