Vitamin <scp>D</scp> Deficiency in Elderly Women in Nursing Homes: Investigation with Consideration of Decreased Activation Function from the Kidneys

Abstract

Frail elderly adults living in nursing homes with poor renal function had lower 1,25(OH)(2) D(3) and higher intact PTH levels and were thus thought to have poorer vitamin D activating capacity. Supplementation with cholecalciferol may be insufficient in people who have poor renal function.
