Keyword:  手臂振动病冷水复温率影响因素;
Abstract: 目的 检测和评估某新型制造企业中手传振动水平,初步探讨手传振动作业工人手臂损伤症状的影响因素.方法 以某企业振动作业工人为研究对象,现场检测振动暴露水平,并问卷调查工人一般情况和手臂症状,测定冷水复温率;分析高血压、高血压家族史及体质指数与冷水复温率和手臂症状的关联.结果 所测振动水平4h等能量频率计权加速度值A(4)为4.28 ~ 15.09(7.97±3.04)m/s2;81.3%的工人自述有手臂症状;77.5%的工人冷水复温率异常.高血压、高血压家族史和体质指数≥28与冷水复温率关联的比值比(OR)及95%可信区间(95%CI)在校正年龄、吸烟和饮酒后分别为1.12(0.60 ~ 5.79)、0.84(0.20 ~ 3.10)和0.64(0.36~3.56);高血压、高血压家族史和体质指数≥28与工人手臂自觉症状关联的OR值及95%CI在校正年龄、吸烟和饮酒后分别为1.80 (0.86 ~ 7.19)、1.02 (0.77 ~ 4.81)和0.75 (0.68~5.27).结论 该新型制造企业中手传振动危害严重.尚未发现高血压、高血压家族史和高体质指数与工人手臂损伤有明显关联.
