Increased parathyroid hormone (PTH) was associated with cardiovascular mortality and morbidity in CKD patients. Our aim was to investigate the associations among estimated glomerular filtration rate (eGFR), albumin/creatinine ratio (ACR) and PTH independent of 25-hydroxyvitamin D (25(OH)D). This study included 9,162 individuals who completed the baseline survey of the Dong-gu Study, which was conducted in Korea from 2007 to 2010. The eGFR, ACR, PTH and 25(OH)D were measured in participants who met the detailed inclusion criteria. After being adjusting for covariates (sex, age, waist circumference, smoking, alcohol intake, physical activity, hypertension medications, diabetes medication, total cholesterol, triglyceride, HDL cholesterol) and log-ACR, the PTH value stratified by 25(OH)D level significantly decreased with increasing eGFR levels in each 25(OH)D stratum. Moreover, after adjustment for the same covariates and log-eGFR, the PTH value stratified by 25(OH)D level significantly increased with increasing ACR levels in each 25(OH)D stratum. In conclusion, the PTH values significantly decreased with increasing eGFR levels and increased with increasing ACR levels independently of 25(OH)D in an adult Korean population ≥50 y of age.
