摘要:
目的 探究不同高血压(high blood pressure,HBP)参照标准对广州市7~12岁儿童进行HBP诊断的差异性,为儿童HBP参照标准的应用提供参考。 方法 于2017年3月~5月,通过分层整群随机抽样,选取广州市7~12岁小学生7698人进行问卷调查及体格测量。儿童HBP诊断分别采用5种标准:米杰2010、米杰2017、马军2017、美国2004和美国2017标准。 结果 上述5种标准对于广州市7-12岁儿童HBP的检出率分别为17.08%、19.23%、12.59%、9.84%、18.31%。基于米杰2017标准的HBP检出率略高于米杰2010标准,但都明显高于马军2017标准;与米杰2010标准比较,米杰2017标准对高收缩压和高舒张压的诊断一致性均高于马军2017标准。与美国2017标准比较,米杰2017标准对高收缩压的诊断一致性高于马军2017标准(Kappa值:0.846 vs.0.727),但对高舒张压的诊断一致性则相反(Kappa值:0.833 vs.0.849)。 结论 广州市7~12岁儿童HBP检出率水平较高。基于米杰2017标准的儿童HBP检出率最高,其次为美国2017标准,且两者的HBP诊断一致性很高;马军2017与米杰2010或美国2017标准的诊断一致性均低于米杰2017标准。 Abstract:Objective To compare the differences in the hypertension prevalence among children aged 7-12 in Guangzhou based on different references of hypertension. Methods A total of 7698 children aged 7-12 years old in Guangzhou were recruited by stratified cluster random sampling method. Demographic information such as gender and age was collected by questionnaire. Children's height, weight, and blood pressure were objectively measured. There were five references for diagnosing children's hypertension: Mi 2010, Mi 2017, Ma 2017, America 2004, and America 2017 reference. Results Based on the references above, the prevalence of hypertension for children aged 7-12 in Guangzhou reached a very high level. The prevalence of hypertension, high systolic blood pressure (SBP) and high diastolic blood pressure (DBP) based on Mi 2017 reference were all higher than those based on Mi 2010 reference, but both of them were distinctly higher than Ma 2017 reference. Compared with Mi 2010 reference, the agreement of diagnosis of high SBP and high DBP were both higher for Mi 2017 than those for Ma 2017. The agreement of high SBP was higher between Mi 2017 and America 2017 than that between Ma 2017 and America 2017 (Kappa: 0.846 vs. 0.727). Conclusion The prevalence of hypertension in children aged 7-12 in Guangzhou reachs a very high level. The prevalence of hypertension based on Mi 2017 reference is the highest and follows with America 2017 reference, and the agreement between them is excellent. Compared with Mi 2010 or America 2017 reference, the agreement for Ma 2017 is lower than that for Mi 2017 reference, respectively. -
