目的了解徐州市儿童青少年超重和肥胖情况及其对血压的影响。方法采用分层整群抽样方法,在徐州市随机抽取小学、初中、高中、大学共12所学校,共计抽取2 147人。采用Excel录入数据,使用SPSS 19.0进行统计分析。结果徐州市儿童青少年超重检出率为17.9%,肥胖检出率为13.3%,不同性别超重肥胖检出率差异均有统计学意义(χ^2=83.745,P<0.01);高血压检出率为8.2%,不同性别高血压检出率差异有统计学意义(χ^2=5.225,P<0.05);正常组、超重组、肥胖组高血压检出率分别为6.6%、9.4%、15.0%;多因素logistics回归分析结果显示:性别、年龄、超重和肥胖是儿童青少年高血压的危险因素。结论徐州市儿童青少年超重、肥胖检出率较高;超重肥胖组高血压检出率比体质量正常组高。

Overweight,obesity and their effects on blood pressure in children and adolescents in Xuzhou City

Objective To understand the status of overweight, obesity and their effects on blood pressure in the children and adolescents in Xuzhou City. Methods A total of 2 147students in 12 schools (primary schools, junior high schools, senior high schools ans universities) in Xuzhou City were randomly selected by the adopted stratified cluster sampling survey method, and they were classified in each grade and investigated. The data were inputted into Excel and statistically analyzed by SPSS 19.0. Results The detection rates of overweight and obesity were 17.9% and 13.3% respectively in the children and adolescents in Xuzhou City. The detection rates of overweight and obesity in the males were significantly higher than those in the females (χ2=83.745, P<0.001). The detection rate of hypertension was 8.2%, and there was a statistically significant difference between different sexes (χ2＝5.225, P<0.05). The detection rates of hypertension in the normal group, overweight group and obese group were 6.6%, 9.4% and 15.0% respectively. The multivariate logistic regression analysis showed that sex, age, overweight and obesity were risk factors for hypertension in children and adolescents. Conclusion The prevalence rates of overweight and obesity among children and adolescents were higher in Xuzhou City. The prevalence rates of hypertension in the overweight and obesity groups were higher than the rate in the normal weight group.
