Abstract: ObjectiveTo know the prevalence of children's hypertension and the relationship between blood pressure and physical morphology level indexes.MethodsAnhui province's data of the national survey on Chinese students'physical fitness and health in 2005 was analyzed.ResultsThe prevalence of hypertension was 13.2% among the students of Anhui province.The prevalence was significantly lower in aged 7,9,11,13,14,19 than that of the other groups(P=0.000).The boys had significantly higher rates of hypertension than girls aged 10 and 17,but the situation was reverse at groups aged 12 and 20(P<0.001).The prevalence of children's hypertension in Suzhou city was higher than Hefei and Huangshan city,existed statistical significant difference in groups aged 8～10 and aged 15～18(P<0.01).The correlated factors of systolic and diastolic pressure were height,weight,body mass index,chest circumference and waist circumference.ConclusionThe children's blood pressure were positivelycorrelated with physical morphology development indexes,such as height,weight,body mass index,as well as age,sex and region.
