Independent factors associated with serum levels of 25- Hydroxyvitamin D in very elderly Chinese males

Abstract

Background: Vitamin D deficiency has been associated with a wide variety of chronic diseases and even all-cause mortality. Data on serum 25-hydroxyvitamin D [25(OH)D] and its independent factors in very elderly (aged 80 years or more) males remain to be fully explored. This study was designed to identify independent factors associated with the serum levels of 25(OH)D in very elderly Chinese males.
