Abstract: Background　The prevalence of hypertension in childhood increases year by year. Childhood hypertension will bring long-term health risks to the human body. As it is often asymptomatic，early diagnosis and treatment are the key to effective management of this disease. However，the blood pressure monitoring management model for preschool children is not clear. Objective　To develop a simple and feasible community-based blood pressure monitoring mode for preschool children. Methods　From January to July 2018，our research group entrusted Tuanjiehu Community Health Center to screen for hypertension in preschool children（n=382） in its service coverage area，and the children were given stratified management according to their blood pressure levels（blood pressure monitoring methods and hypertension diagnostic criteria adopted were from the 2010 Blood Pressure Reference Standards for Chinese Children and Adolescents）. Results　The screen identified 42（11.0%） children with hypertension，38（9.9%） with elevated blood pressure and 302（79.1%） with normal blood pressure. Then the blood pressure of the hypertensive children was remeasured twice，but four of them were lost to follow up during the measurement process. Three of them were still hypertensive after three-time measurement were transferred to the cardiovascular clinic of a higher level hospital for clinical diagnosis and treatment. The 47 children with elevated blood pressure（including the above-mentioned 38 children with elevated blood pressure and 9 children who were found with hypertension in the first measurement but were identified with elevated blood pressure in 2 subsequent measurements） were given life behavior interventions according to the results of a survey using the Life Behavior Questionnaire developed by our research group. And the 328（85.9%） children with normal blood pressure were given the routine management of the community health center. Both the rates of self-awareness of suffering from hypertension and receiving hypertension management were 90.5%（38/42）. The average systolic blood pressure of male children was higher than that of female children〔（98±9） mm Hg vs.（95±9） mm Hg〕（P=0.001）. The average diastolic blood pressure of male children was similar to that of female children〔（55±8） mm Hg vs.（55±7）mm Hg〕（P>0.05）. Conclusion　Using this community-based blood pressure monitoring mode，children can receive stratified management according to their blood pressure levels，and those with hypertension can be identified early and transferred to higher level hospitals timely，so this mode is of great significance in early detection and treatment of childhood hypertension.
