In the offspring of gestational or long-term diabetic mothers the following findings
were obtained: (1) Immunoreactive plasma insulin levels on the first day of life were
weakly correlated to the thickness of the skin-fold at the neck on the third day of
life (n = 82; r = 0.27; P < 0.05). (2) A significant correlation was found between
the plasma insulin levels at birth and the basal as well as the maximal plasma insulin
values after glucose loading (1.75 g/kg b. wt.) at 2 years of age (for basal values:
? = 25; r = 0.53; P < 0.01; and for maximal values: n = 21; r == 0.63; P < 0.01).
(3) A highly significant correlation was even observed between the thickness of the
neck-fold at 3 days of age and the fasting plasma insulin levels at 3—8 years of age
(n = 26; r = 0.61; P < 0.001). These findings suggest that perinatal hyperinsulinism
and perinatal obesity, induced by maternal hyperglycaemia and/or overnutrition during
pregnancy, are risk factors for persistent hyperinsulinaemia predisposing to diabetes
mellitus and cardiovascular disease in later life.
