汉族与回族人群外周血管阻力及其相关因素的比较

 目的 对宁夏回族自治区银川市汉族与回族人群外周血管阻力的差异及其相关影响因素探讨和分析。方法 采用美国Bioz.com数字化无创血液动力学监护仪,检测了2 795名汉族和1 886名回族人群体循环血管阻力（SVR）、体循环血管阻力指数（SVRI）、收缩压（SBP）、舒张压（DBP）、体质量指数（BMI）、心输出量（CO）、心指数（CI）、心率（HR）、平均动脉压（MAP）,同时进行相关因素的分析。结果 1﹚回族16～18岁和30～39岁男性SVR分别显著高于相应年龄的汉族男性（P<0.01,P<0.05）。2）回族16～18岁男性SVRI显著高于相应年龄的汉族男性（P<0.01）。多元线性回归显示：对回、汉两民族之间SVR差异影响的强弱依次为MAP、CI、HR、SBP及DBP;对SVRI影响的贡献大小指标顺序与SVR一致。结论 回族SVR/SVRI高于汉族可能与遗传及生活方式有关。

Comparison of the systemic vascular resistance and the correlative factors in Han and Hui populations of China

Objective this study on the difference in systemic vascular resistance (SVR) and related factors between Han and Hui residents were explored and analyzed. Methods 2795 Hans and 1886 Huis from Yin Chuan and He Lan areas of Ning Xia province were detected with Bioz.com digital non-invasive hemodynamic monitor from the US, a lot of indicators were determined ,including systemic vascular resistance (SVR), systemic vascular resistance index(SVRI), body mass index(BMI), diastolic blood pressure(DBP),systolic blood pressure(SBP), cardiac output(CO), cardiac output index(CI), heart rate(HR), mean arterial pressure(MAP).at the same time ,the relevant factors were analyzed. Results (1)Hui aged 16～18 and 30～39 year old male SVR were significantly higher than the corresponding ages of Han males( P<0.05 ).(2) Hui aged 16～18 year old male SVRI were significantly higher than the corresponding ages of Han males( P<0.05 ).Multiple linear regression: the strength of the impact of SVR difference between the Hui and Han population is followed by MAP, CI, HR, SBP and DBP; the order of indicators of the contribution on the SVRI was consistent with the SVR. Conclusion the higher SVR/SVRI are possibly related to genetic and lifestyle of Hui , compared with that of Han residents.
