儿童少年血压的轨迹现象

TRACKING OF BLOOD PRESSURE IN CHILDREN AND ADOLESCENTS

对１１９７名初测年龄７～１４岁儿童进行３年的纵向研究。用追访血压Ｚ值与初测血压Ｚ值的相关系数描述轨迹现象的大小。收缩压和舒张压的相关系数范围分别是０．３０～０．５７和０．２２～０．４１。血压偏高组轨迹现象最明显。初测体重是血压持续偏高的影响因素。

longitudinal study was carried out in 1197 school children initial aged 7-14 years old for 3 years.Tracking coefficient,defined as the correlation between follow up BP Z score and initial BP Z score,was described “tracking phenomenon”.Tracking coefficient were 0 30 to 0 57 for SBP,0 22 to 0 41 for DBP.The probability of remaining the same rank was higher in the upper quintile.Initial weight was the factor that influenced persistence of higher blood pressure.The data implied that the children with higher BP and higher weight were more likely to develope sustained high BP.
