Background:
Diabetes is an independent risk factor for the development of coronary heart disease (CHD). We evaluated whether there are racial/ethnic differences in predicted probability of CHD among persons with type 2 diabetes from the 1999-2002 National Health and Nutrition Examination Survey.
Methods:
Adults with type 2 diabetes without cardiovascular disease (n=585) were evaluated; the United Kingdom Prospective Diabetes Study (UKPDS) Risk Engine was used to develop estimates of CHD and Framingham Risk Score (FRS) was used to assess the 10-year CHD risk. Chi-square tests and analysis of variance were used to assess differences between racial/ethnic groups in risk factors and predicted probability for CHD.
Results:
Risk factors for CHD differed significantly amongst the three racial/ethnic groups. Whites had lower mean A1C concentrations (7.3%+/-0.2) than blacks (8.1%+/-0.2, P<0.05) or Mexican Americans (8.1%+/-0.2, P<0.05). Systolic blood pressure was higher in blacks compared with whites (P<0.05) and in Mexican American men compared with white men (P<0.05). Total cholesterol differed insignificantly by race/ethnicity whereas high-density lipoprotein cholesterol was higher in blacks compared with whites and Mexican Americans. Blacks had the greatest 5, 10, 15, and 20-year predicted risks of CHD among men, whereas whites had the greatest predicted risks among women. When evaluated by the FRS, the 10-year predicted risk of CHD was estimated to be 22.5% by UKPDS and 17% using FRS.
Conclusions:
UKPDS estimates of probability of CHD were similar across race/ethnicities, indicating that the risk factors tended to balance out. Despite differences in individual risk factors, the estimated risk for CHD was similar for all persons with diabetes.

Carbohydrate Metabolism
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in the...
