Abstract: Objective To understand the correlation between blood pressure (BP) and body mass index (BMI) of children and adolescents in Urumqi,so as to provide support for the prevention of hypertension in children and adolescents in this area. Methods A total of 41 028 children and adolescents from 15 high school,junior high school and primary school were selected based on the principle of convenient sampling in Urumqi City from September to October in 2016.The height,weight and blood pressure were tested and analyzed. Results The detection rate of hypertension among children and adolescents in Urumqi City was 12.75%,and boys had significantly higher hypertension rate than girls(13.77% vs.10.92%,χ²=75.31,P<0.01).Moreover,the detection rates of high systolic blood pressure,high diastolic blood pressure and hypertension in children and adolescents with obesity and overweight were higher than those in normal students,and the differences were significant (χ²=758.8,114.2,623.0,P<0.01). Conclusions The blood pressure of children and adolescents in Urumqi is not optimistic.Overweight and obesity are the main causes of hypertension in children and adolescents.In the future,the blood pressure of overweight and obese children should be given more concerns

摘要： 目的 了解乌鲁木齐市儿童青少年血压与体重指数 (BMI)的相关性,为该地区儿童青少年血压偏高的预防提供依据。方法 2016年9－10月本着方便抽样的原则在乌鲁木齐市分别选取15所高中、初中和小学的41 028名儿童青少年,进行身高、体重和血压的测试,并对结果进行分析。结果 乌鲁木齐市儿童青少年血压偏高检出率为12.75%,男生(13.77%)高于女生(10.92%),差异有统计学意义(χ²=75.31,P＜0.01)。儿童青少年肥胖和超重的学生高收缩压、高舒张压、血压偏高的检出率均高于正常组学生,差异有统计学意义(χ²=758.8、114.2、623.0,P＜0.01)。结论 乌鲁木齐市儿童青少年的血压状况不容乐观,超重肥胖是导致儿童青少年血压偏高的主要原因,今后应对超重肥胖儿童青少年的血压引起足够重视和关注。
