目的研究体质指数、腰围与血压水平以及高血压患病率之间的关系。方法采用整群抽样的方法,对2011年11月~2012年2月在中国人民解放军总医院国际医学中心进行体检的全部体检人群共计3 903人的血压、身高、体重和腰围(WC)进行测量,计算体质指数(BMI)。结果体重过低人群收缩压为(105.2±12.9)mm Hg,舒张压为(69.1±7.5)mm Hg;正常体重人群收缩压为(115.5±15.6)mm Hg,舒张压为(75.4±9.3)mm Hg;超重人群收缩压为(123.7±15.9)mm Hg,舒张压为(80.4±9.2)mm Hg;肥胖人群收缩压为(129.5±17.2)mm Hg,舒张压为(83.8±10.7)mm Hg。随着体质指数的增加,血压水平以及高血压患病率均逐渐增加,差异有统计学意义(P<0.05)。腰围正常人群的收缩压为(114.4±16.0)mm Hg,舒张压为(74.5±9.6)mm Hg;腹型肥胖人群的收缩压为(124.3±16.5)mm Hg,舒张压为(80.8±9.6)mm Hg。腹型肥胖人群的血压水平和高血压患病率高于腰围正常人群,差异均有统计学意义(P<0.05)。结论血压水平和高血压患病率与体质指数和腰围呈正相关。
Objective To study the relationship between body mass index, waist circumference and blood pressure and the prevalence of hypertension. Methods A total of 3 903 blood pressure, height, weight and waist circumference (WC) were measured in all the medical examinations in the International Medical Center of Chinese People’s Liberation Army General Hospital from November 2011 to February 2012 by cluster sampling method , Calculate body mass index (BMI). Results Systolic blood pressure was (105.2 ± 12.9) mm Hg and diastolic blood pressure (69.1 ± 7.5) mm Hg respectively in subjects with low body weight. Systolic blood pressure was (115.5 ± 15.6) mm Hg and diastolic blood pressure was (75.4 ± 9.3) mm (123.7 ± 15.9) mm Hg and diastolic blood pressure (80.4 ± 9.2) mm Hg respectively in the overweight population. The systolic blood pressure was (129.5 ± 17.2) mm Hg and the diastolic blood pressure was (83.8 ± 10.7) mm Hg in the obese group. With the increase of body mass index, the blood pressure level and the prevalence of hypertension increased gradually, the difference was statistically significant (P <0.05). Systolic blood pressure was (114.4 ± 16.0) mm Hg and diastolic blood pressure (74.5 ± 9.6) mm Hg respectively in the normal waist circumference group; (124.3 ± 16.5) mm Hg and (80.8 ± 9.6) mm Hg. The prevalence of hypertension and blood pressure in abdominal obese people were higher than those in normal waist people, the difference was statistically significant (P <0.05). Conclusion The prevalence of hypertension and blood pressure are positively correlated with body mass index and waist circumference.
