Objective: The aim of the screening program was to investigate blood pressure levels in different ages according to obesity. Methods: 2202 adolescent (1326 girls, 876 boys) participated in the screening program. Blood pressure, heart rate, body composition, bodyweight, height and BMI were assessed. Results: The mean systolic blood pressure of all screened adolescents was 126.34-t-12.55 mmHg. Boy/girl values were 131.87+13.59/117.49+5.69 mmHg, p<0.001. The mean diastolic blood pressure of all screened adolescents was 71.86+8.74 mmHg. Boy/girlvalues were 72,61'+917166.69-+5.04 mmHg, p<0.001. The 50%,90%,95%, and g9% thresholds and cases for systolic, diastolic blood pressure, and the BMI and body fluid thresholds, detailed lor 14-18 year olds, girls and boys, are tabulated. Systolic blood pressure (SBP) was over 99% in '12 girls (14-year-olds), 39 (15), 42 (16),33 (17), 5 (18) to height. SBP was over 99% in 17 boys (14-year-olds), 73 (15), 100 (16), 33 (17), 5 (18) to height. lt is emphasized that systolic blood pressure (SBP) is> 99% in 12 girls ('14 years), 39 (15), 42 (16),33 (17),5 (18) to body height. SBP>99% for 17 boys (14 years),73 (15), 100 (16),33 (17),5 (18) to body height. Elevated diastolic values were associated with elevated systolic values, but less occurred. The percentage of high blood pressure was more frequent among boys and girls who were in the overweight group (58.6% and 18.6%). Conclusions: Normal blood pressure is higher in overweight and obese adolescents and is a significant risk factor for developing high blood pressure in young adulthood.  Kulcsszavak: bloodpressure in childhood, bodyheight, BMI
