Aims To study the glucose disappearance rare and fasting blood glucose as p
redictors of Type 2 diabetes in a 22.5-year prospective follow-up of 1947 h
ealthy non-diabetic men.
Subjects and methods Of a cohort of 2014 Caucasian men, the 1947 who had bo
th fasting blood glucose < 110 mg/dl and an intravenous glucose tolerance t
est were included. A number of other physiological parameters were also det
ermined at baseline. Multivariate Cox regression analyses were used to inve
stigate the possible significance of the glucose disappearance rate and fas
ting blood glucose as predictors of Type 2 diabetes.
Results After 22.5 years' follow-up, 143 cases of Type 2 diabetes had devel
oped. Glucose disappearance rare and fasting blood glucose were moderately
correlated (r = -0.32). Men in the lowest quartile of glucose disappearance
rate and highest quartile of fasting blood glucose had markedly higher dia
betes rates than all other men (P < 0.0001). After adjusting for each other
, age, diabetes heredity, body mass index, physical fitness, triglycerides,
cholesterol and blood pressure (Cox model), both glucose disappearance rat
e and fasting blood glucose remained major predictors of diabetes.
Conclusions Glucose disappearance rate and fasting blood glucose are, in sp
ite of low intercorrelation, major long-term predictors of Type 2 diabetes
in healthy non-diabetic Caucasian men.
