Cardiovascular risk factors in Turkish immigrants with type 2 diabetes mellitus:Comparison with Dutch patients

Background: Based on recent epidemiological studies the need for a similar approach towards management of cardiovascular risk factors in type 2 diabetics with different ethnic background can be questioned. We compared the prevalence of cardiovascular risk factors and 10-year absolute risk for a coronary heart disease between Turkish and Dutch type 2 diabetes patients. Methods: A cross-sectional study was performed using data-bases from three Dutch studies on type 2 diabetes, comparing 147 Turkish to 294 Dutch diabetes patients, matched for age and gender. Main outcome measures were: total (t-) cholesterol, high-density lipoprotein cholesterol (HDL), low-density lipoprotein cholesterol (LDL), triglyceride, blood pressure, and smoking. The 10-year absolute risk for a coronary event was calculated by means of the Framingham risk equation. Results: In Turkish diabetics t- cholesterol was lower than in Dutch (5.4 vs. 5.9 mmol/l; p <0.001), in Turkish males HDL was lower than in Dutch male patients (0.94 vs. 1.08 mmol/l; p = 0.04). The total/HDL-cholesterol ratio in Turkish and Dutch diabetics was equal (5.4 vs. 5.4). Less Turkish than Dutch females smoked (9% vs. 23%; p <0.01). The 10-year absolute risk for a coronary event in both Turkish and Dutch male patients was 24%; the risk in Turkish vs. Dutch females was 13% vs. 15% (not significant). Conclusion: The absolute risk for a coronary event in Turkish type 2 diabetes patients is similar to the risk in Dutch diabetes patients, although important differences in the risk pro. le exist, in particular, the lipid profile and smoking habits differ.
