【摘要】 微处理机在流行病学上的广泛应用,使探讨多因素病因中的主要危险因素进入了新阶段。本文对93例高血压病例进行了1:1配对的病例对照研究,运用逐步回归分析方法,从22个因素中筛选出与高血压病有关的主要危险因素有心电图Sv₁+Rv₅、尿钾（负相关）、心率、β脂蛋白、家族史等,为进一步探讨病因指出了研究方向。更多还原

【Abstract】 This paper reported the results of a case-control study about essential hypertension occurring in a work site of a railway constructive section. Among 93 pairs of patients, suspected factors of 22 were investigated. Under the control of some confounding factors （such as age, sex, etc,） and by the stepwise regression analysis of multifactors, there were 5 factors related to the elevation of pressures, ie, S_v1+R_v5, lower urea potassium level, heart rate, B-lipoprotein level and the family history of hypertension. Alcohol comsumption and the index of over weight were related to the elevation of diastolic pressure, and the serum triglyceride level was related to the elevation of systolic pressure only.更多还原
