Link between gestational diabetes and vitamin D

The Dutch researchers analysed data that included a total of 2146 participants, 433 of whom had been diagnosed with gestational diabetes.

They found a significant inverse relationship between serum 25OHD and incidence of GDM, with vitamin D levels less than 50nmol/l being associated with greater than 1.6 times incidence of GDM.

It remains to be seen whether that association is causal, the authors said.
