摘要
对１１９７名７～１４岁学龄儿童进行３年纵向研究．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．血压偏高级轨迹现象最明显．初测体重是血压持续偏高的影响因素．提示血压偏高且肥胖的儿童成为持续性血压偏高者的可能性较大．
A longitudinal study was carried out in 1197 school children initial age 7～14 years 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 influencing persistence of higher blood pressure.The data imply that the children with higher BP and higher weight are more likely to develop.sustained high BP.
