Risk factors for cardiovascular disease predict the development of diabetes among Utah families

In 1989, we sent a medical follow-up questionnaire to 2,728 members of 98 Utah families originally screened from 1980 to 1983 in the Cardiovascular Genetics Research Clinic. The response rate was 69.9%. Of 1,134 nondiabetic individuals initially age 18 or older who returned the questionnaire, 10 were found to be newly diagnosed with diabetes. The incidence of diabetes was higher among individuals who were found at baseline to have central obesity, lipid abnormalities, especially increased triglyceride levels, and hypertension. Family histories of coronary heart disease and diabetes were not related to the development of diabetes. Our findings that cardiovascular disease risk factors predict the development of diabetes in this relatively young, Caucasian population are consistent with the results of studies from several different populations.
