BMI=body mass index; cFPG1=first capillary fasting plasma glucose; cFPG2 = second capillary fasting plasma glucose; FPG = fasting plasma glucose; vFPG = venous fasting plasma glucose; GDM = gestational diabetes mellitus; IFG = impaired fasting glucose; NFG = normal fasting glucose.
Note: Statistical analysis of the low-risk group was not possible because of the small numbers.
a Conversion factor to SI units: ×0.0555.
bP <.05 in high-risk group.
cP <.01 in high-risk group.
dP <.001 in high-risk group.
