深圳市中小学生血压与体质量指数的关系

探讨深圳市中小学生血压与体质量指数(BMI)的关系,为高血压的早期预防提供参考.方法 抽取深圳市小学、初中、高中各10所共40 989名学生为研究对象,对学生身高、体重和血压数据进行测量和分析.结果 高血压检出率达12.49%,高收缩压和高舒张压检出率分别为9.07%和5.70%.不同营养状况学生高血压、高收缩压、高舒张压检出率差异均有统计学意义(X2值分别为340.630,668.535,101.548,P值均<0.01),肥胖学生高血压、高收缩压和高舒张压检出率均最高,分别为23.79%,19.72%和9.61%;营养正常学生高血压、高收缩压和高舒张压检出率分别为10.67%,7.38%和5.15%.相关性分析显示,不同性别学段学生收缩压、舒张压均与BMI呈正相关(P值均<0.01).结论 深圳市中小学生血压状况不容乐观,血压与BMI存在正相关,应多关注超重肥胖儿童的血压状况.

Relationship between blood pressure and body mass index among primary and middle school students in Shenzhen

Objective To understand the correlation between blood pressure and body mass index(BMI) among primary and middle school students in Shenzhen and to provide reference for early prevention of hypertension.Methods A total of 40 989 students from 10 primary,10 middle and 10 high schools in Shenzhen were selected as the subjects.Height,weight and blood pressure were examined.Results The prevalence of hypertension among students in Shenzhen reached 12.49%.The detection rates of high systolic pressure and high diastolic pressure were 9.07% and 5.70% respectively.The detection rates of hypertension,high systolic pressure and high diastolic pressure were higher among obese students(23.79%,19.72% and 9.61%),compared with students with normal BMI,which was 10.67%,7.38% and 5.15% respectively.Correlation analysis indicated that systolic and diastolic blood pressure were positively correlated with BMI in male and female students(P<0.01).Students with higher BMI had elevated systolic and diastolic blood pressure.Conclusion The status of blood pressure among primary and middle school students in Shenzhen is not optimistic.Consider significant association between elevated blood pressure with high BMI,the need to always conduct blood pressure monitoring for all obese students is also recommended.
