目的了解甲醛和噪声对血压的联合作用。方法收集某厂1995年的职业体检资料，对心血管系统部分指标进行统计学分析。结果甲醛、噪声联合作业组收缩压(SP)、舒张压(DP)、心率(PR)的平均值及血压升高发生率均高于甲醛组、噪声组，且各指标均呈噪声组、甲醛组、联合组顺序递增分布趋势，其中联合组的SP、DP值及血压升高发生率与其他两组间的差异有显著性意义(P<0.05)。各组工人临床主诉症状及实验室检查指标间差异无显著性意义。结论通过调查分析发现，甲醛和噪声对心血管系统存在着联合作用。

Objective To study the combined effect of formaldehyde and noise on blood pressure. Methods To sort out data of occupational somatoscopy of one factory in 1995, the indexes about cardiovascular system were statistically analysed. Results The level of systolic pressure(SP),diastolic pressure(DP) and incidence rate of hypertension in association group of formaldehyde and noise were higher than in formaldehyde group and noise group. Distribution tendence of all indexes was association group > formaldehyde group > noise group. The significant difference in the level of SP, DP and incidence rate of hypertension between association group and other two groups was found. No significant difference in complained symptom of workers and laboratory examination indexes in the three groups. Conclusion According to this researches, the combined effect of formaldehyde and noise on the cardiovasular system was comfirmed.
