Introduction: Theoretically, first-degree relatives (FDRs) of type 2 diabetes mellitus (T2DM) are predisposed to have earlier and more severe atherosclerosis than non-FDR due to hereditary insulin resistance. A previous study reported that atherosclerotic plaques were found in 45.2% of young adults FDR of T2DM, but the study did not include non-FDR as control group. The aim of this study was to compare subclinical atherosclerosis (carotid intima-media thickness, CIMT) between FDR of T2DM and non-FDR.
Method: This was a cross-sectional study involving 16 FDR subjects and 16 age-sex matched non-FDR subjects, aged 19–40 years, with normal glucose tolerance and no hypertension. Collected data included demographic characteristic, anthropometric measurement (BMI and waist circumference), laboratory analysis (fasting blood glucose, HbA1c, lipid profile), and CIMT examination (using B-mode ultrasound).
Results: The mean of CIMT in the FDR group was higher than that in the non-FDR group (0.44 mm vs 0.38 mm, p=0.005). After adjusting for waist circumference, BMI, low-density lipoprotein cholesterol, and triglyceride, CIMT maintained significant difference between FDR and non-FDR subjects. BMI and waist circumference showed moderate correlation with CIMT.
Conclusion: CIMT in young adult FDR of T2DM is thicker than that in age-and sex-matched non-FDR population.
