ADIPOQ and gestational diabetes: In a multicenter study, researchers found that lower maternal VD levels in obese pregnant women made them more vulnerable to GDM and they had lower adiponectin, with a positive association between serum 25(OH)D concentrations and HMW-adiponectin level (r = 0.27, p = 0.007), indicating that adiponectin might serve as a predictor of GDM [148].
