摘要 目的应用超声瞬时波强(WI)研究儿童青少年体质量指数(BMI)对颈动脉血管弹性的影响及其相关性。方法应用WI对单纯肥胖组及正常对照组内中膜厚度在正常范围的颈动脉血管进行检测,所测各参数与BMI做相关性分析。结果与正常对照组相比,单纯肥胖组瞬时减速度波强、僵硬度(β)、压力应变系数(Ep)、瞬时波强脉搏波传导速度、脉搏波传导速度值增高,顺应性值降低(P<0.05)。瞬时加速度波强、脉搏波反射增强指数、瞬时波强负向波面积值在2组间依次增高,但差异不具有统计学意义。相关分析显示,总人群中BMI与β及Ep间存在单因素相关关系(P<0.05)。多元线性回归分析显示,BMI可以独立对血管弹性进行预测。结论 BMI对颈动脉血管弹性有明显影响,可独立对血管弹性进行预测。WI为检测血管弹性的较好技术手段。
