Abstract

Objective To understand the feature of blood pressure in children aged 7 to 12 years in Zhengzhou. Methods According to stratified cluster random sampling method, children aged 7 to 12 years in five schools from three urban and two suburban counties in Zhengzhou were analyzed. The height, weight, waist circumference, hip circumference, systolic blood pressure (SBP), and diastolic blood pressure (DBP) were measured and analyzed. Results  The survey included total 6460 children aged 7 to 12 years, 3206 urban children (49.63%), 3254 suburban children (50.37%), 3525 boys (54.57%) and 2935 girls (45.43%). SBP in boys [(117.86±18.18) mmHg] was significantly higher than that in girls [(113.82±13.11) mmHg (t=3.16; P=0.002). The incidence of hypertension in children in Zhengzhou was 7.52%. The blood pressure in boys was higher than that in girls (χ2=9.66, P=0.002). The blood pressure in urban boys and girls was higher than that in suburban boys and girls respectively (χ2=24.15, 14.39; P=0.000). The SBP and DBP had positive correlation with age, height, weight, BMI, waist circumference in boys (P<0.01). The SBP had positive correlation with age, height, weight, BMI, waist circumference in girls (P<0.01). Conclusions  The blood pressure is higher in boys than in girls, which also is higher in urban children than in suburban children in Zhengzhou. The SBP is related to the age, height, weight, BMI, waist circumference.
