目的:探讨儿童营养过剩性肥胖与儿童血压偏高的相关性。方法:以体重指数(BMI)作为体质状况指标,采用分层随机整群抽样的方法,对庆元县500名7～15岁儿童的BMI及血压进行横断面的调查,并对两者之间的相关性进行分析。结果:在排除年龄、性别的影响后,7～15岁儿童的BMI与收缩压(SBP)和舒张压(DBP)均呈独立正相关关系,偏相关系数分别为0.2873和0.2113(P<0.05);且SBP和DBP随BMI值的增加而增加(P<0.05)。SBP与DBP超标率以及患高血压的相对危险度(RR)均随BMI值的增加而增高。BMI与SBP、DBP的Logistic回归分析结果提示,年龄和BMI对SBP和DBP的值有影响(P<0.05)。在调整年龄因素后,儿童体重分类每升高一级,患高血压的RR分别是低一级体重分类的2.45倍;其RR的95%CI为2.10-2.75。结论:庆元县7～15岁儿童的BMI与SBP、DBP独立正相关,超重和肥胖者患高血压的危险性显著增加。
Objective: To investigate the correlation between children’s overweight obesity and high blood pressure in children. Methods: The body mass index (BMI) was used to investigate the BMI and blood pressure of 500 children aged 7-15 years in Qingyuan County by stratified stratified random cluster sampling method. The relevance of the analysis. Results: After excluding the influence of age and gender, BMI was positively correlated with systolic blood pressure (SBP) and diastolic blood pressure (DBP) in children aged 7-15 years. The partial correlation coefficients were 0.2873 and 0.2113 (P <0.05) ; SBP and DBP increased with the increase of BMI (P <0.05). SBP and DBP over-rate and the relative risk of hypertension (RR) increased with the increase of BMI. Logistic regression analysis of BMI, SBP and DBP indicated that age and BMI had an impact on SBP and DBP (P <0.05). After adjusting for age, the children with a weight-bearing class had a higher level of RR at 2.45-fold lower body weight classifications, respectively. The 95% CI of RR was 2.10-2.75. Conclusion: The BMI of SBP and DBP in children aged 7-15 years in Qingyuan County are independently and independently related to the risk of hypertension in overweight and obesity patients.
