influence of renal function on vitamin D metabolism in the very elderly
OBJECTIVES: Hypovitaminosis D and chronic kidney disease (CKD) are highly prevalent in older adults. The factors correlating with 25-OH-vitamin D and PTH levels were analyzed in older adults with and without CKD. DESIGN: We performed a cross-sectional analysis embedded within the BELFRAIL study.

RESULTS: There was no correlation between the presence of CKD and low 25-OH-vitamin D levels, but there was a significant (p<0. 01) correlation between CKD and high PTH levels. Among the participants with a normal eGFR, the LAPACQ score, vitamin D supplementation, season, log PTH value and eGFR were correlated with log 25-OH-vitamin D levels. Among the participants with CKD, only vitamin D supplementation, log PTH levels and serum calcium levels were correlated with log 25-OH-vitamin D levels. Gender, log 25-OH-vitamin D values, serum calcium and phosphorus levels and eGFR were correlated with log PTH values in the patients with normal eGFR. Log 25-OH-vitamin D values, serum phosphorus levels, vitamin D supplementation (p=0.07), season (p=0.10) and eGFR were correlated with log PTH values in the patients with CKD. CONCLUSION: Exposure to sunshine and an active lifestyle were correlated with higher 25-OH-vitamin D levels in older adults without CKD. The PTH level in patients with CKD may be influenced by the season.</description><identifier>ISSN: 1279-7707</identifier><identifier>EISSN: 1760-4788</identifier><identifier>DOI: 10.1007/s12603-012-0094-0</identifier><identifier>PMID: 23364486</identifier><language>eng</language><publisher>Paris: Springer-Verlag</publisher><subject>Aged, 80 and over ; Aging ; Belgium ; Biological and medical sciences ; blood serum ; calcium ; Calcium - blood ; cholecalciferol ; Cholecalciferol - blood ; Cholecalciferol - therapeutic use ; Cohort analysis ; cohort studies ; Dietary Supplements ; educational status ; elderly ; Exercise ; Feeding.
