诊室噪声对血压测量值的影响

目的探讨诊室噪声对诊室血压测量值的影响。方法本研究为横断面研究,连续选取2015年1月至2016年6月于河南省人民医院心内科门诊就诊的、能提供近30 d内家庭自测血压数据、且符合入组标准的869例,按照就诊时诊室噪声是否符合《中华人民共和国国家标准声环境质量标准》(昼间≤55 dB)分为2组,比较诊室内血压值与家庭自测血压值的差异(|△SBP|),并采用有序多分类logistic回归分析相关影响因素。结果诊室噪声超标组(>55 dB)诊室收缩压及|△SBP|均明显高于诊室内噪声达标组(≤55 dB)[(144.04±21.58)mmHg比(140.06±18.11)mmHg,P=0.003;(13.44±14.67)mmHg比(9.52±12.19)mmHg,P<0.001],在校正了年龄、性别、体质指数、高血压病史、糖尿病病史、吸烟史、饮酒史后,logistic回归分析提示诊室噪声达标与|△SBP|相关(OR=0.648,95%CI:0.494~0.850)。结论诊室内噪声是否达标影响诊室内收缩压测量值与家庭自测收缩压值间的差异。

Effects of noise on office blood pressure measurement

Objective To investigate the influence of office noise on blood pressure measurement.Methods A total of 869 eligible people were consecutively recruited from cardiac clinic of Henan Province People s Hospital from January 2015 to June 2016.Subjects were divided into 2 groups according the noise level of clinic based on the national standards for acoustic environmental quality of People s Republic of China(daytime≤55 dB),blood pressure data were analyzed with T-test and logistic regression analysis.Result The mean SBP and|△SBP|measured in relatively high noise group was significantly higher than those measured in low noise group[(144.04±21.58)mmHg vs.(140.06±18.11)mmHg,P=0.003;(13.44±14.67)mmHg vs.(9.52±12.19)mmHg,P<0.001,respectively].Logistic regression analysis indicated that the noise meet the standard(≤55 dB)was significantly associated with|△SBP|(OR=0.648,95%CI:0.494-0.850).Conclusions The level of noise in the consulting room is associated with the difference in SBP measured in home and clinic.
