OBJECTIVE
This study was undertaken to determine whether women with Turner syndrome have greater subclinical atherosclerosis and evaluate the relationship to risk factors for atherosclerosis. METHODS: 18 Women with Turner syndrome and 18 women as control group were measured the intima media thickness (IMT) of common carotid artery by B-mode ultrasound. We compared the IMT between cases and controls, and analyzed risk factors which affect the IMT. RESULTS: There are no differences between the groups in age and body mass index (BMI). The height was shorter (147.8+/-7.9 vs 160.3+/-5.9, p<0.001) and the waist-hip ratio (WHR) was significantly increased in Turner syndrome (0.86+/-0.04 vs 0.78+/-0.04, p<0.001). Fasting blood sugar (FBS) (90.1+/-9.9 vs 79.4+/-4.4 mg/dl, p<0.001), fasting insulin (9.5+/-3.0 vs 4.7+/-1.0 IU/ml, p=0.009), total cholesterol (187.1+/-21.3 vs 154.8+/-21.8 mg/dl, p=0.014), and LDL (111.3+/-10.0 vs 82.8+/-16.4 mg/dl, p=0.009) were significantly higher in Turner syndrome. Compare to control, the IMT was significantly increased in Turner syndrome (0.61+/-0.09 vs 0.49+/-0.02 mm, p=0.002). In the analysis of correlation between the IMT and clinical & biochemical characteristics, Turner syndrome status, WHR, FBS and fasting insulin were significantly affecting factors (Coefficients of correlation: 0.720, p<0.001; 0.671, P<0.001; 0.445, p=0.020; 0.904, p<0.001). CONCLUSION: These results suggested that women with Turner syndrome might have an increased risk of subclinical atherosclerosis and insulin resistance was most important risk factor. |
