Abstract: Objectives To investigate the distribution of blood pressure (BP) in healthy children and adolescent from Hebei province and further discuss the correlation between BP and sex, age, and growth indexes (including height, weight and BMI etc). Methods To select randomly people to be investigated from 2 cities and 2 countries in Hebei by stratified sampling. BP values and its related indexes in 5268 healthy children and adolescent aged 10~18 years old were examined and analyzed. Results BP increased with age in children and adolescent. BP values in the young of cities were significantly higher than that of countries (p<0.001), especially diastolic blood pressure (DBP). The prevalence of high BP in males and females was 7.5% and 6.8, respectively. And the total percentage of high BP was 7.2%. These were all higher than those reported before. Systolic BP (SBP), DBP, weight and BMI of children and adolescent in high BP group were all significantly higher than those of the same sex and age in normal BP group (p<0.001). Pearson correlation analysis showed positive correlation between BP and age, height, weight and BMI, of which correlation coefficients of BP and height and weight for males and BP and weight for females were higher compared with others. Conclusion The total prevalence of high BP was higher than that reported before in the same region ; High weight or obese children and adolescent should control their weight to reduce the risk of primary hypertension.
