基于非同日三时点筛查儿童高血压的单中心研究

Prevalence of pediatric hypertension during three separate visits based on one center cross‑sectional study

于2019年11-12月在桓台县某所小学选取1243名8~13岁儿童进行横断面调查,所有变量完整者共1238名。随访第一、二、三时点分别纳入1238、146、83名研究对象;随着随访次数的增加,三时点均受访的83名研究对象的收缩压和舒张压水平均明显降低(P趋势值均<0.05);三个时点血压偏高检出率分别为11.8%、6.8%和4.0%(P趋势值<0.001),其中收缩压偏高检出率分别为11.4%、6.5%和4.0%(P趋势值<0.001),而舒张压偏高检出率分别为1.1%、1.0%和0.4%(P趋势值>0.05)。

From November to December 2019,a cross-sectional study including 1243 children aged 8~13 years was conducted in one primary school in Huantai County,and 1238 children with complete data were finally included.A total of 1238,146,and 83 children were included in the first,second and third visit of the follow‑up,respectively.With the follow‑up visits increasing,the systolic blood pressure(SBP)and diastolic blood pressure(DBP)levels of the 83 children who were followed up across all three different visits decreased significantly across three different visits(both Pfor trend<0.05).The prevalence of elevated blood pressure across the three visits was 11.8%,6.8%and 4.0%(Pfor trend<0.001);the prevalence of elevated SBP was 11.4%,6.5%,and 4.0%(Pfor trend<0.001);the prevalence of elevated DBP was 1.1%,1.0%,and 0.4%,respectively(Pfor trend>0.05).
