Body mass index is inversely associated with arterial stiffness in Chinese adults with primary hypertension: results from the China Stroke Primary Prevention Trial (CSPPT)
2017
ABSTRACTBackground: This study aimed to elucidate the relationship between body mass index (BMI) and the presence of arterial stiffness in rural-dwelling Chinese adults with primary hypertension. Methods: Primary hypertension patients (n = 19,375) receiving an average of 4.5 years of antihypertension therapy were selected from the Chinese Stroke Primary Prevention Trial (mean age: 64.7 ± 7.4 years, male: 37.8%). Anthropometric, demographic, hemodynamic, and biochemical data were obtained. Arterial stiffness was assessed using brachial-ankle pulse wave velocity (baPWV). Results: BMI was inversely associated with baPWV after adjusting for gender, age, smoking, alcohol consumption, center, pulse, SBP, DBP, FBG, TC, TG, HDL-C, BUN, Scr, UA, HCY, antidiabetes treatment, lipid-lowing treatment, and antihypertensive treatment (β (SE): –10.72 (0.69), P < 0.0001). Quintile1 (Q1) was used as a reference; Q2, Q3, Q4, and Q5 groups were all inversely associated with baPWV. The β increased with increasing BMI, β (SE) ...
