目的 探讨儿童青少年肥胖与血压的关系,为心血管病的早期预防和干预提供依据。方法 以参加2010年全国学生体质与健康调研的青岛市7~17岁4 841名儿童青少年为研究对象,按照中国学龄儿童青少年超重肥胖筛查标准以及中国儿童青少年血压参考标准,采用χ²检验、标准离差法和多因素logistic回归分析等进行分析。结果 青岛市7~17岁超重和肥胖总检出率分别为15.37%和11.59%,男生高于女生。血压偏高的总检出率为30.4%,男生高于女生,城市高于乡村。血压Z分从高到低依次是肥胖组、超重组、体重正常组。血压偏高组的BMI值(20.58±4.42)高于正常组(18.85±3.47)。多因素分析显示,城乡、性别、年龄和BMI均是血压的影响因素。结论 青岛市中小学生血压偏高的总检出率高于山东省。年龄较大的城市肥胖男生发生高血压概率较高。

Analysis of relationship between obesity and blood pressure in the children and adolescents

Objective To investigate the relationship between obesity and blood pressure in children and adolescents in order to provide evidence for early prevention and intervention for the cardiovascular disease. Method 4 841 7~17 year old children and adolescents were selected in Qingdao from National Student Physical Fitness and Health survey in 2010,for the study.We used the chi-square test,standard deviation method and multivariate logistic regression analysis for analysis according to overweight and obesity screening standards and blood pressure reference standard of children and adolescent in China. Results Overweight and obesity detection rate of 7~17 year old students in Qingdao was 15.37% and 11.59%,respectively.Rate of boys was higher than girls.High blood pressure detection rate was 30.4%,and the rate of boys was higher than girls.The rate in urban was higher than in rural.Blood pressure Z-score in descending order were obese group,overweight,normal weight group.BMI in the high blood pressure group 20.58±4.42 was higher than the normal group 18.85±3.47.Multivariate analysis showed that urban and rural areas,gender,age and BMI were the influencing factors of blood pressure. Conclusion High blood pressure detection rate in Qingdao was higher than which in Shandong province.Older urban obese boys had high probability of hypertension occurrence.
