摘要
目的比较臀围相关肥胖指数识别儿童高血压的诊断价值,为促进儿童高血压的早期筛查提供参考。方法采用分层整群随机抽样法,抽取秦皇岛市5所小学1 352名7~12岁汉族学生进行问卷调查及身高、体重、臀围、血压等指标测量。结果共检出高血压小学生82例(6.1%),其中男生46例,检出率为6.8%;女生36例,检出率为5.3%。男生收缩压(SBP)与体质量指数(BMI)(r=0.49)、腰围(WC)(r=0.50)、臀围(HC)(r=0.50)、人体肥胖指数(BAI)(r=0.26)和儿童人体肥胖指数(BAIp)(r=0.45)均呈正相关,舒张压(DBP)与BMI(r=0.23),WC(r=0.24),HC(r=0.24),BAI(r=0.11)和BAIp(r=0.21)均呈正相关(P值均<0.01)。女生SBP与BMI(r=0.44),WC(r=0.40),HC(r=0.48),BAI(r=0.20)和BAIp(r=0.44)均呈正相关,DBP与BMI(r=0.30),WC(r=0.28),HC(r=0.34),BAI(r=0.14)和BAIp(r=0.31)均呈正相关(P值均<0.01)。男生各臀围相关指数识别高血压的ROC曲线下面积分别为HC:0.87,BAI:0.61,BAIp:0.79(P值均<0.05),女生各臀围相关指数识别高血压的ROC曲线下面积分别为HC:0.84,BAI:0.71,BAIp:0.82(P值均<0.01)。HC识别儿童高血压的ROC曲线下面积与BMI和WC比较差异无统计学意义(P值均>0.05)。结论臀围相关肥胖指标可作为识别儿童高血压的有效指标。BAI和BAIp并不优于HC。
