ABSTRACT
Carbohydrate metabolism was evaluated in 21 twin pregnancies and in 21 women with singleton pregnancies. The groups were matched for age, weight, parity, and period of gestation. A 100-g oral glucose tolerance test was performed on all 42 subjects. No significant differences in venous plasma glucose responses were found between singleton and twin pregnancies. The only significant difference between the insulin responses of the two groups was a lower plasma insulin concentration at 60 min in the twin group (P less than 0.03).

Glycosylated haemoglobin (Hb A1) values were estimated immediately after delivery in 29 patients who had given birth to a large infant, in 25 who had delivered a macerated stillborn infant, and in 31 controls matched for age and parity. No difference in mean Hb A1 values was found between mothers of normal-sized and of large infants. The mean Hb A1 level for the mothers who had delivered a macerated stillborn infant was higher than that for the control group (8,26% v. 7,65%). Although this was not statistically significant, there were 5 patients with a raised Hb A1 value and a normal glucose tolerance test result; this may suggest gestational diabetes.

Carbohydrate metabolism was evaluated in 26 women with a twin pregnancy and 26 women with a singleton pregnancy. The groups were similar in respect of age, parity and gestational age. Each woman had an oral glucose tolerance test. No significant differences in venous blood sugar values or insulin responses were found between singleton and twin pregnancies.
