THURSDAY, Aug. 22 (HealthDay News) -- Before full-blown diabetes
sets in, people typically develop a syndrome known as
"prediabetes." Now a new study shows that people who are not obese
but who have a family history of diabetes are at higher risk of
becoming prediabetic, too.
Prediabetes is a condition where blood sugar levels are higher
than normal, but not as high as seen in diabetes.
It was known that a family history of type 2 diabetes increases
a person's risk of diabetes, but it was not known if it increased
the risk of prediabetes.
In the study, researchers led by Dr. Andreas Fritsche of the
German Center for Diabetes Research looked at more than 5,400
people with normal blood sugar levels and more than 2,600 with
After taking into account age, sex and body fat, the researchers
concluded that people with a family history of diabetes were 26
percent more likely to develop prediabetes.
Further analysis showed that the link between a family history
of diabetes and prediabetes risk was seen only in people who were
notobese, according to the study which was published Aug. 21
in the journal
One expert not connected to the study said the finding raises
"It is interesting to note that this association was not demonstrated in those who were obese," said Dr. Alyson Myers, an endocrinologist at North Shore University Hospital in Manhasset, N.Y. "It would be helpful to look at these patients over time -- rather than at one point in time as was done in this study -- to see how these rates would change with weight loss or gain."
The study authors offered up their own theory on why the
connection was most evident among slimmer people. "This might
indicate [that] the effect of family history on prediabetes becomes
readily measurable only when not overshadowed by strong risk
factors such as obesity," they wrote.
