江苏省7—13岁儿童血压与超重和肥胖的相关性研究

目的探讨7～13岁儿童血压与超重和肥胖的相关性，为成年期心血管疾病的早期预防提供参考依据。方法按照经济水平，分层随机选取江苏省4个县区的8所学校进行调查，调查资料包括儿童体检和家庭问卷调查，应用相关和偏相关分析的统计方法进行分析儿童血压与超重和肥胖的关系。结果对3693名7—13岁儿童的体质指数（bodymassindex，BMI）值与血压进行相关分析，结果显示儿童BMI值与儿童收缩压（systolicbloodpressure，SBP）、舒张压（diastolicbloodpressure，DBP）呈显著相关（均有P〈0．001），相关系数（r）分别为0．312和0．217；不同体重组间比较发现，SBP和DBP的均数都是肥胖组〉超重组〉体重正常组，差异具有统计学意义（均有P〈0．001）；分别比较SBP高、DBP高以及血压高和不高组的BMI值，分析发现SBP高、DBP高、血压高者的BMI值显著高于SBP不高、DBP不高、血压不高者，t检验结果显示，差异均有统计学意义（均有P〈0．001）。结论超重、肥胖对儿童血压升高有影响，控制超重和肥胖是减少儿童高血压的重要措施。

Association study of blood pressure levels with overweight and obesity among 7-13 years old children in Jiangsu Province

Objective To evaluate the relationship of hypertension with overweight and obesity among 7-13 years old children, and to provide basis for the early prevention against the adult disease. Methods Data were collected from 7- 13 year old children from four counties. BMI with SBP and DBP of 3 693 children was studied by correlation analysis. Re- suits BMI, SBP and DBP of 3 693 children had significant correlation, the correlation coefficient was 0. 312 and 0. 217 respectively. The means of SBP and DBP in the obesity group were the highest. The second was those of the overweight group and the normal group. The prevalence of hypertension in the obesity group was the highest, t test results showed that the difference was statistically significant. Conclusions There is significant relationship between the high blood pressure and BMI among 7-13 years-old Children. The priority is to prevent overweight and obesity in order to prevent hypertension a- mong children.
