中国7～12岁儿童血压与年龄身高的关系

Analysis of the relationship among blood pressure,age and height in 7-12 years old children

目的探讨中国7～12岁儿童血压受年龄和身高的影响及其作用规律,为儿童青少年血压评价和相关标准制定提供科学依据。方法运用1985年全国学生体质与健康调研7～12岁汉族学生数据,从每个省中随机抽取相同数量的同年龄、同性别、同身高学生,分别控制年龄、身高后,分析身高和年龄对儿童青少年血压的影响。结果在未控制身高、年龄时,男、女生收缩压、舒张压随年龄增长而上升;控制年龄后,男、女生7～12岁收缩压、舒张压总体呈随身高增长而升高的趋势(P值均<0.05);控制身高后,男、女生各年龄组间血压水平差异无统计学意义(P值均>0.05)。结论 7～12岁儿童血压水平随身高增长而升高,受年龄影响较小。

Objective To explore the relationship among blood pressure,age and height in 7-12 years-old children and to provide evidence for making blood pressure standard of children.Methods The data were from physical fitness and health surveillance of Chinese school students in 1985.The same amount of students were randomly selected by age,gender and height from every province.The relationship between height and blood pressure was analyzed when age and height was controlled separately.Results Both the boys＇ and the girls＇ blood pressure increased with age,without height and age being controlled.After age being controlled,the blood pressure level of boys and girls aged 7-12 was increased with the growth of height（P0.05）.When height was controlled,on the whole,the difference between age and blood pressure were not significant（P0.05）.Conclusion Blood pressure increases with the growth of height in 7-12 years-old children,which is affected little by age.
