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8 633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(χ2=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 understand the prevalence of hypertension in 7 ~ 15-year-old students in Lanzhou and provide the basis for preventing hypertension. Methods By cluster sampling method, a total of 8 633 students from 12 primary schools and 3 junior high schools in Lanzhou City were sampled in 2012 for physical and blood pressure measurement. Results The positive rate of high blood pressure was 4.59% and the rate of high blood pressure was 2.24% in 7 ~ 15 years old children in Lanzhou. The detection rate of normal high blood pressure was higher in boys than in girls (χ2 = 6.492, P = 0.011). Students high blood pressure and high blood pressure detection rate increases with age. The detection rate of normal high value systolic blood pressure (SBP) was 4.06%, normal high value diastolic blood pressure (DBP) was 3.88%, the detection rate of SBP high blood pressure was 1.88%, the detection rate of DBP high blood pressure was 1.93% . The detection rate of normal high value systolic blood pressure of girls was 3.43%, that of normal high diastolic blood pressure was 2.51%, that of SBP high blood pressure was 1.65%, and that of DBP high blood pressure was 1.68%. Conclusion The detection rate of abnormal blood pressure in children with Lanzhou is low, and the prevention and treatment of hypertension in children in this area should be strengthened.
