大学生体质量指数与血压的相关性研究

Correlative studies of college students' BMI and blood pressure condition

目的研究大学生人群体质量指数(body mass index,BMI)的特征,探讨其与血压的相关性,从而为大学生制订有针对性的高血压干预策略。方法将12824名大学生入校时的体检资料输入计算机,建立Excel表进行数据处理,并进行统计学分析。结果大学生的BMI均数为20.64kg/m2,男大学生的BMI均数为21.52kg/m2,女大学生的BMI均数为19.79kg/m2,两者差异有显著意义。BMI分级后血压以收缩压≥140mmhg和(或)舒张压≥90mmhg为阳性标准,阳性率显著上升,消瘦、正常体质量、体质量超标、轻度肥胖任意两组间血压阳性率的增加差异有显著意义。男大学生人群血压阳性率显著高于女大学生。结论大学生BMI数值的分布类似钟型,右侧扁平,BMI大于均值的范围较分散。从大学生人群的整体研究以及男女大学生的对比研究,皆表明BMI的增加与血压阳性率高度相关。从控制高血压的危险困素角度,新生入学体检后应对所有的体质量超标及肥胖人群登记管理,进行有针对性的综合干预。

Objective To study the features of body mass index （BMI） of college students and explore its correlation with their blood pressure, so as to formulate the intervention strategy for the prevention of hypertension. Methods The health check data of 12 824 new college students were inputted into the computer, processed with Excel, and analysed statistically. Results The average BMI for college students was 20.64 kg/m^2, the average BMI for boy students 21.52 kg/m^2 and the average BMI for girl students 19.79 kg/m^2, and there was a significant difference between the boy students and grid students. After gradation of BMI, with systolic pressure ≥140 mmHg and/or diastolic pressure ≥90 rnmHg as the positive standard, the positive rate increased obviously, and there were significant differences between any of two groups： below weight, average weight, overweight, slighdy obese. The positive rate of blood pressure in boy students was significandy higher than that in girl students. Conclusions The distribution of college students BMI value is similar to the shape of a clock, the right side is fiat, the scale of BMI higher than average is comparatively vast. From the entire studies of college students and the contrastive studies of boy students and girl students, they both dernoustrate the high correlative relationship between the increase of the BMI and the positive rate of blood pressure. From the perspective of controlling the hypertension danger factors, after the new college students＇ health check, all the groups of overweight and obsess students should be registered and managed, and some comprehensive intervention measures should be conducted.
