Participant characteristics
We studied 73 women with GDM and 73 women with uncomplicated pregnancy.
Women with GDM, compared to controls, were older and were more of Black
racial origin but there was no difference in weight and body mass index
between the groups (Table 1). In the GDM group, 23 women were on diet,
24 on metformin and 26 were on insulin alone or insulin and metformin.
Women with GDM delivered approximately one week earlier compared to
controls. There was no difference in birthweight z score between the two
groups.
