摘　　要：目的：动态血压监测探讨患者体重指数与血压变化情况。方法：选择门诊和病房住院的患者共691例（其中男性417例，女性274例），年龄范围13～90岁，平均年龄为55岁。所有观察对象测量诊室血压、心率、身高、体重和监测24小时动态血压等指标，按照体重指数分为3组，体重指数〈24为正常体重组；24≤体重指数〈28为超重组；体重指数≥28为肥胖组。结果：肥胖组患者24小时和白天的平均收缩压／舒张压、夜间平均舒张压以及24小时、白天和夜间心率均高于正常体重组，有显著性差异（P〈0．05～0．01）。此外，血压负荷也随着体重指数的增加而增加，有显著性差异（P〈0．05～0．01）。结论：体重指数与动态血压和血压负荷有较密切的关系；与正常体重组、超重组比较，肥胖组患者的血压最高、心率最快；动态血压提供的数据信息量大，结论更可靠、准确。Objective ：To examine the relationship between body mass index （BMI）and parameters obtained from 24-hour ambulatory blood pressure monitoring（ABPM）. Methods：A total of 691 outpatients and inpatients（417 males,274 females）with ages from 13 to 90 years（ average age：55 years） were recruited into this study and were divided into three groups：normal,overweight and obesity according to body mass index （BMI）. Clinic blood pressure, height, weight and heart rate were measured in all patients. ABPM was applied to the nondominant arm between 8：00Am to 10：00Am. Results：The mean 24-hour and daytime systolic and diastolic blood pressure, mean night diastolic blood pressure,along with mean 24-hour, daytime and night heart rate were significantly higher in the obesity group than the normal group （P 〈 0.01 ）. In addition, the blood pressure load increased with the BMI. Conclusion ： BMI is closely correlated with 24-hour blood pressure, blood pressure load and heart rate. The obese patients had the highest blood pressure and heart rate. Substantial evidence may be obtained from ABPM.
