兰州市7～15岁学生高血压流行病学调查

Epidemiological survey of hypertension among 7-15 years old children

目的了解兰州市7-15岁学生高血压流行现况，为学生高血压预防提供依据。方法采用整群抽样的方法，于2012年抽取兰州市12所小学和3所初中在校学生共8633名，进行体格和血压测量。结果兰州市7-15岁儿童正常高值血压检出率为4．59％，高血压检出率为2．24％；男生正常高值血压检出率高于女生（X^2=6．492，P=0．011）。学生正常高值血压和高血压的检出率都随着年龄的增长而增高。男生正常高值收缩压（SBP）检出率为4．06％，正常高值舒张压（DBP）检出率为3．88％；SBP高血压检出率为1．88％，DBP高血压检出率为1．93％。女生正常高值收缩压检出率为3．43％，正常高值舒张压检出率为2．51％；SBP高血压检出率为1．65％，DBP高血压检出率为1．68％。结论兰州市儿童血压异常检出率低，仍应加强预防该地区儿童高血压的发展。

Objective To learn the prevalence of hypertension among 7-15 years old children living in Lanzhou. Methods By using cluster sampling method 8 633 students were chosen from primary and junior school in Lanzhou. Physical examination and blood pressure test were given to all the participants. Results The high-normal blood pressure rate among 7- 15 years old students was 4.59%,and hypertension rate was 2.24%. The high-normal blood pressure rate was higher in male than that in female( χ2= 6.492,P = 0.011). The rate of high-normal blood pressure and hypertension were both increasing with age growing. The systolic high-normal blood pressure rate of boys was 4.06%; and the rate of diastolic was 3.88%. The systolic blood pressure rate was 1.88%,and the high diastolic blood pressure rate was 1.93%. The systolic high-normal blood pressure rate of girls was 3.43%; and the rate of diastolic was 2.51%. The systolic blood pressure rate was 1.65%,the high diastolic blood pressure rate was 1.68%.Conclusion Though the high blood pressure of children in Lanzhou is lower than other regions,the prevention from hypertension among children should be enhanced.
