【摘要】 目的探讨北京市7～17岁儿童青少年血压与肥胖状态[依据不同划分标准:体重指数(BMI)、腰围(WC)、体脂百分比(FMP)]的关系。方法选取2004年4月至10月进行的"北京市儿童青少年代谢综合征研究"(BCAMS)中19488名7～17岁儿童青少年(男9824名,女9664名)为研究对象,按照BMI、WC、FMP标准分别划分儿童青少年超重和肥胖状态,分析其血压与BMI、WC、FMP关系,高血压状态的变化及趋势。结果各种划分标准中血压按正常、超重和肥胖组顺序依次升高;控制年龄和性别后,BMI、WC、FMP与收缩压(SBP)和舒张压(DBP)成独立正相关关系(P<0.001);BMI、WC、FMP超重组和肥胖组的高血压发生率显著高于正常组,差异有统计学意义(P<0.001),肥胖组患高血压的相对危险度是正常组的3～7倍;BMI分组分别与FMP、WC分组组合,BMI肥胖,FMP肥胖组及BMI肥胖,腹型肥胖组患高血压风险分别是正常组的7.3和6.8倍。结论儿童青少年BMI、WC和FMP与SBP和DBP密切相关,用BMI指标预测儿童青少年高血压风险较WC及FMP更敏感;儿童青少年超重和肥胖增加高血压的发生风险,其高血压发生率随着肥胖程度增加呈现成倍上升趋势。更多还原

【Abstract】 Objective To analyze the relationship between blood pressure and BMI,waist circumference(WC) and fat mass percentile(FMP) among children and adolescents(7～17 years) in Beijing. Methods As part of the Beijing Children and Adolescent Metabolic Syndrome Study(BCAMS),data of weight,height,FMP,WC,and blood pressure were collected from 19 488 subjects aged 7～17 years from April to October in 2004. Overweight and obesity were defined according to BMI,WC and FMP criteria. Analyze the relationship between blood pressure and BMI,WC and FMP,as well as the change and trend of hypertension. Results The levels of SBP and DBP increased in the order of normal weight to overweight and obesity. With age and gender controlled,BMI,WC and FMP were independently positively correlated with SBP and DBP (P < 0.001). The incidence of hypertension was significantly higher in the BMI,WC and FMP overweight and obesity groups than in the normal group,and the difference had statistical significance. The relative risk of hypertension in the obesity group is 3 to 7 times that of the normal group,and the risk in BMI obesity/FMP obesity group and the BMI obesity/abdominal obesity group was 7.3 and 6.8 times that of the normal group respectively.Conclusion BMI,WC and FMP are closely related to SBP and DBP in children and adolescents. BMI is a better index for hypertension:the heavier the childrn,the higher the risk of hypertension.更多还原
