Low levels of 25-hydroxy vitamin D and active 1,25-dihydroxyvitamin d independently associated with type 2 diabetes mellitus in older Australian men: the concord health and ageing in men project.

摘要

25OHD and 1,25OHD levels were associated with DM. The independent association between serum 25OHD and 1,25OHD concentrations and DM raises the question of whether each of the two vitamin D metabolites may influence DM through different biological mechanisms and pathways.
