Keyword:  剂量-反应关系高血压累积噪声暴露量Logistic回归模型噪声声压级;
Abstract: 本文分三个阶段对稳态噪声暴露人群的高血压调查资料进行多因素分析。发现声压级与高血压患病率之间存在剂量一反应关系。用Logistic回归模型校正多个危险因素的影响后,声压仍是一个高血压病的独立的危险因素,其OR(OddsRatio)值为1.031,P<0.05。在校正年龄与工龄高度相关(r=0.966)在此模型中产生多元共线性的缺点后,OR值为1.033,年龄OR值由1.101增大至1.157,其对高血压病的危险性约为累积噪声暴露量的3倍。在两个模型中父母高血压史和吃菜咸淡对高血压病的危险性约分别为噪声暴露的2倍左右。发现公式CNE=声压级+k×[In(工龄)In(2)]中,多危险因素同时进入模型,以k=2.9时模型的最大似然值最大,该数值非常接近于3,支持噪声暴露与健康危害关系的等能量学说。
