Abstract: Objective To validate a Simplified Height Specific Blood Pressure (BP) Table for screening high blood pressure (HBP) among children and adolescents in Suzhou,in order to provide reference for making strategies for preventing childhood HBP. Methods A total of 6 972 children and adolescents aged 7 to 17 years were selected in this study by stratified cluster random sampling method from 2017 to 2018,and were asked to fill out questionnaires,meanwhile their height,weight and BP were measured.According to Chinese Blood Pressure Reference for Children and Adolescents aged 7-18 years (WS/T 610-2018) (hereafter referred to as "gold standard"),a simplified height specific BP table was developed.Validation of HBP and high normal BP (HNBP) was assessed. Results According to gold standard and simplified height specific BP table,the detection rates of HNBP in children and adolescents aged 7 to 17 years in Suzhou were 16.7% and 16.6%,respectively,and the detection rate of HBP was 12.7% and 12.8%.Paired chi-square test showed that there was no significant difference on the prevalence of HNBP and HBP identified by two standards (χ²=1.376,P=0.711).Performance of simplified height specific BP table was in good agreement with gold standard.When screening HNBP,the area under the curve (95%CI),sensitivity,specificity and Kappa value were 0.900(0.887-0.913),83.2%,96.8%,and 0.803,respectively.And corresponding values for screening HBP were 0.925(0.911-0.938),86.9%,98.0%,and 0.848,respectively. Conclusion Simplified height specific BP table is easy to use,and it shows satisfying effect for screening HNBP and HBP.
