不同肥胖测量指标对北京市社区人群动脉僵硬度的评价

Objective The aim of this study was to investigate the relationship between obesity measured by body mass index(BMI), waist circumference(WC), waist-to-hip ratio(WHR)]and arterial stiffness on community populations in Beijing area. Methods In a cross-sectional study of 2664 subjects(1379 men and 1285 women)aged(53.19 ± 15.73 years, mean±standard deviation), BMI, WC, WHR and other cardiovascular risk factors, were measured and carotidfemoral pulse wave velocity(cfPWV)was measured to assess the arterial stiffness. All the data were analyzed with linear correlation analysis, univariate analysis and stepwise regression method to explore the relationship between obese indexes and arterial stiffness. Results We noticed that a showed the existence of positive correlations between BMI(r=0.0829,P＜0.01)and cfPWV, WC(r=0.2659, P＜0.01)and cfPWV, WHR(r=0.2749, P＜0.01)and cfPWV, in univariate analysis,cfPWV was associated with WC≥85 cm(male)or ≥80 cm(famale)(P＜0.01), WHR≥0.90(male)or≥ 0.85(famale)(P＜ 0.01). Stepwise regression analysis revealed that WC was an independent risk factor of cfPWV, other than age, gender, systolic blood pressure, HDL-C, OGTT2h etc. Conclusion Our findings indicated that obesity was an independent risk factor of cfPWV, which was an early marker of cardiovascular and renal diseases, among community population in Beijing area. There were different relationships between obesity measurement parameters(BMI, WC, WHR)and cfPWV.
