Logistic regression analysis for SGA based on maternal glycaemic parameters

Variables	Crude	P value	Adjusted*	P value
	OR (95% CI)		OR (95% CI)
75 g OGTT 0-hour glycaemia	0.39 (0.29 to 0.53)	<0.001	0.4 (0.29 to 0.55)	<0.001
75 g OGTT 1-hour glycaemia	1.06 (0.97 to 1.15)	0.217	1.04 (0.95 to 1.14)	0.365
75 g OGTT 2-hour glycaemia	0.88 (0.82 to 0.95)	0.001	0.88 (0.81 to 0.95)	0.002
FPG in second trimester	0.74 (0.57 to 0.97)	0.026	0.77 (0.59 to 1.01)	0.063
2-hour postprandial glucose in second trimester	0.79 (0.71 to 0.88)	<0.001	0.81 (0.73 to 0.9)	<0.001
HbA1c in the second trimester	2.28 (1.6 to 3.25)	<0.001	2.4 (1.64 to 3.52)	<0.001

Bold values were statistically significant.

*Adjusted for parity, previous uterine scar, history of low birth weight, history of abortion or miscarriage, macrosomia, gestational hypertensive disorder, oligohydramnios, anaemia, pre-pregnancy body mass index, height, gestational weight gain rate and ketonuria in first trimester.

FPG, fasting plasma glucose; HbA1c, haemoglobin A1c; OGTT, oral glucose tolerance test; the third trimester of pregnancy, 33–37 gestational weeks.
