[Prevalence of pediatric hypertension during three separate visits based on one center cross-sectional study].

ABSTRACT

From November to December 2019, a cross-sectional study including 1 243 children aged 8~13 years was conducted in one primary school in Huantai County, and 1 238 children with complete data were finally included. A total of 1 238, 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).
