Clustering of cardiovascular risk factors in hyperinsulinemia in Japanese without diabetes.
Clustering of cardiovascular risk factors in hyperinsulinemia was investigated in 247 Japanese subjects without diabetes. After adjustment for age and sex, the highest quartile of the summed values of insulin concentrations after oral glucose loading showed high odds ratios (OR; 95% confidence intervals) for the prevalence of cardiovascular risk factors: OR = 2.02 (1.07-3.83) for hypertension, 3.91 (1.82-8.40) for hypertriglyceridemia, 2.41 (1.30-4.46) for low high-density lipoprotein cholesterol, 2.41 (1.28-4.51) for impaired glucose tolerance, and 3.58 (1.44-8.88) for high uric acid. Two or more of these factors were clinically elevated in 50% of those in the highest quartile of the summed values of insulin, compared to 16-28% of those in the lower three quartiles. These findings were slightly attenuated after further adjustment for body mass index and sum of skinfolds. In conclusion, multiple risk factors for cardiovascular disease existed in the subjects with hyperinsulinemia in Japanese without diabetes.
