Non-insulin-dependent (type II) diabetes has a strong familial component.
In 1989-1991, a community-based study of young Caucasian offspring (mean age, 15.3 years) of non-insulin-dependent (type II) diabetics (n=25) and nondiabetics (n=27) representing 13 and 12 families, respectively, was conducted in Bogalusa, Louisiana, to determine whether metabolic abnormalities could be detected in early life.
All offspring were given a 1-hour oral glucose tolerance test.
The offspring of diabetics (versus nondiabetics) had significantly increased measures of body fatness ; blood pressure ; and fasting levels of glucose, insulin, glucagon, insulin-to C-peptide ratio, and triglycerides.
The increases of systolic blood pressure, glucose, and glucagon remained significant after adjustment for differences in body mass index (BMI).
After glucose challenge, only plasma glucose response was significantly higher in the offspring of diabetics, even after controlling for differences in BMI.
None of the offspring of nondiabetics had 30-minute (peak) glucose levels above 161 mg/dl (8.9 mmol/liter), compared with 41% of the offspring from diabetics.
High glucose response and BMI were independently associated with parental diabetes.
These results indicate that it is possible to identify multiple abnormalities in some offspring of type II diabetics at an early age that may presage the onset of overt adult diabetes.
