Hypercholesterolemia in undiagnosed non-insulin-dependent diabetes in southern Taiwan.
The purpose of this study was to investigate the prevalence of hypercholesterolemia among subjects having diabetes and glucose intolerance, according to the guidelines of the National Cholesterol Education Program (Adult Treatment Panel II, ATP II). This survey consisted of 2090 subjects (856 men, 1234 women) aged 30 years or more from the Sun-Ming district of Kaohsiung city. Glucose tolerance status was ascertained for both medical history and a 75-g oral glucose tolerance test according to World Health Organization criteria. Frequency of elevated total cholesterol in female subjects with abnormal glucose tolerance is significantly greater than in those with normal glucose tolerance (NGT). However, only male subjects with undiagnosed NIDDM (UDDM) had a statistically higher rate of hypercholesterolemia than those with NGT. Of UDDM individuals, 68% have total cholesterol level between 200 and 239 mg/dl and two or more risk factors for heart disease or evidence of coronary heart disease or total cholesterol > or = 240 mg/dl or high-density lipoprotein (HDL) cholesterol < or = 35 mg/dl. Such individuals should have their low-density lipoprotein (LDL) cholesterol measured. Using the ATP II, LDL cholesterol levels warranting dietary treatment for hypercholesterolemia would be expected in 76% of UDDM. Due to the high prevalence of coronary heart disease in diabetic patients, investigation of blood lipid levels and coronary heart disease risk factors should be routine in these patients, and treatment strategies should include management of lipid disorders and the many other risk factors. A high frequency of dyslipidemia was found among UDDM group in our study. Early detection of undiagnosed diabetic patients is also very important in decreasing the prevalence of coronary heart disease.
