Abstract
Background: Increase in carotid intima-media thickness (IMT), which can be measured using ultrasound, is a risk factor for atherosclerosis. Fat mass, measured with a body composition analyzer using bioelectrical impedance analysis, is used in the assessment of abdominal obesity, which is associated with a number of diseases that can lead to atherosclerosis. This study investigated the relationship between fat mass measured with a body composition analyzer and carotid IMT in men in their 50s.
Methods: From November 2012 to May 2015, we evaluated a total of 3,351 men in their 50s. All subjects underwent measurement of fat mass and IMT. T-test was used to account for differences in IMT according to medical history and smoking. Univariate correlation analysis was used to check the correlation between the IMT and each variable. In order to check the independent impact of fat mass on the IMT, multiple regression analysis was conducted.
Results: The IMT was greater in patients who had hypertension or diabetes. IMT had positive correlations with age, body mass index, waist circumference, systolic blood pressure, fasting blood glucose level, total cholesterol level, low-density lipoprotein level, triglyceride level and fat mass, while it had a negative correlation with high-density lipoprotein level. On multivariate analysis, fat mass remained an independent factor affecting the IMT.
Conclusion: Fat mass, measured conveniently with a body composition analyzer, may be useful in predicting the possibility of increased IMT, which, in turn, is a risk factor for atherosclerosis.
