唐钢高温作业工人高血压调查

Epidemiological Study of Hypertension in Tangshan Steelplant Workers

对唐钢3816名(男3484,女332)高温作业工人和1047名(男811、女236)非高温作业工人进行了调查。高温女工高血压患病率为4.52％,对照女工为3.81％,两组比较无明显差异。高温男工高血压患病为9.24％(标化率为10.30％),对照男工为6.29％(标化率为5.01％),两组比较有极显著差异。高温男工患病率随高温工龄和高温暴露等级的升高而明显升高。多因素逐步回归分析表明,影响高温工人收缩压和舒张压的主要因素为体重指数、高温暴露等级,参加高温作业时的年龄和高血压家族史;高温主要影响舒张压。

3816 (male 3484, female 332) steelworkers exposed to heat as study population, and 1047 (M. 811, F.236) workers not exposed to heat as controls, were investigated. The prevalences in female study and control groups were 4.52% and 3.81%, respectively, and there was no significant different found. The prevalences of hypertension in male study and control groups were 9.24% and 6.29%, and the adjusted rates were 10.30% and 5.01%, respectively. The differences were all significant. More important, there was an obvious dose-response relationship between hypertension and years of employment and classes of heat exposure. Stepwise regresion analysis shown that over-weight (expresed as IBM), classes of heat exposure, age begin to expose to heat, and family history of hyperten sion were most important factors that affect the level of blood presure. Compaired to SDP the effect of heat exposure was less important than that to DBP.
