Correlation Between The Body Mass Index, The Waist Circumference And The Arterial Stiffness In Healthy And Coronary Artery Disease Uygur Population Of The Xinjiang

Objective:To study the correlation between the body mass index, the waist circumference and the arterial stiffness in healthy and coronary artery disease Uygur population in Xinjiang. Methods:The study included113coronary artery disease patients and92healthy people in the Xinjiang. Their body mass index, waist circumference, and brachial-ankle pulse wave index and biochemical value were measured. In the healthy people and the coronary artery disease patients, the linear correlation analysis is performed with the body mass index, the waist circumference and brachial-ankle pulse wave index. The confounding factors of the brachial-ankle pulse wave index were adjusted. Results:In healthy people, the correlation coefficient of the pulse wave index (PWV) and body mass index (BMI) is0.076, but it is not statistically significant (P>0.05). The correlation coefficient of the PWV and waist circumference is0.218and it is statistically significant (P<0.05). In coronary artery disease patients, the correlation coefficient of the PWV and BMI is0.232, it is statistically significant (P<0.05).The correlation coefficient of the PWV and the waist circumference is0.256(P<0.01). After adjusting for age, gender, and other cardiovascular risk factors, each additional1kg/m2in BMI may be accompanied with an increase of0.053m/s in the PWV, each1cm increase in waist circumference may be accompanied with an increase of0.027m/s in the PWV. Conclusion:Whether in the healthy or coronary artery disease Uygur population, the measure of abdominal obesity (waist circumference) and general obesity (BMI) were associated with arterial stiffness presented by the PWV.
