No full textObjectiveEnhanced fatty-acid desaturation by stearoyl-CoA desaturase enzyme-1 (SCD1) is associated with obesity. This study determined desaturation in the cord plasma of newborns of mothers with and without gestational diabetes (GDM).Study designNewborns of mothers with GDM (n=21) and without (control, n=22) were recruited. Cord plasma fatty-acid desaturation indices (palmitoleic/palmitic, oleic/stearic ratios) were compared, and correlated with anthropometrics and biochemical measures. A subset of very low-density lipoprotein (VLDL) desaturation indices were determined to approximate the liver SCD1 activity.ResultThe total oleic/stearic index was higher in GDM, despite adjustment for cord glucose concentrations. Among GDM and controls, the oleic/stearic index correlated with cord glucose concentrations (rs=0.36, P=0.02). Both palmitoleic/palmitic and oleic/stearic indices correlated with waist circumference (r=0.47, P=0.001; r=0.37, P=0.01). The VLDL oleic/stearic index was higher in GDM.ConclusionThe elevated total oleic/stearic index suggests increased lipogenesis in GDM newborns. Factors in addition to glucose supply may influence fetal SCD1 activity
