Abstract: Objective To analyze the prevalence of hypertension among Han adooescents with different status of obesity in Yanbian area of Jibin province.Methods By cluster random sampling,a total of 1 785 Han adolescents were selected from four high schools in Antu county and height,w eight,w aist circumference(WC),and blood pressure of the abolescents were measured.The body mass index(BMI) and WC were served as the indices of obesity.Results The detection rate of hypertension in the boys with normal BMI,overw eight,and obesity was 18.5%,39.1%,and 56.0%,and that of in the girls was 6.7%,14.3%,and 33.3%,respectively.The prevalence of hypertension was significantly increased along with the increment of BMI(χ_boy²=37.8,χ_girl²=17.9; all P< 0.00).The detection rate of hypertension was significantly higher in the boys with abnormal WC(32.2%) than that of in the boys with normal WC(20.8%,P< 0.05).Multiple logistic regression analyses show ed that the risk of hypertension in the overw eight or obesity adolescents was significantly increased,with the odds ratio(OR) values of 6.008 and 2.668.The value of OR was 3.586 in the abolescents with abnormal BMI and abnormal WC,and that was 2.777 in the abolescents with abnormal BMI and normal WC,and 0.500 in the abolescents with abnormal WC.Conclusion The results show that the increased BMI has a stronger effect on the imcrease of blood pressure than WC,and there is a dose-response relationship betw een hypertension and BMI.Abnormal BMI combined with abnormal WC significantly increases the risk of hypertension.
