[目的 ]描述铸造工人腰背痛流行病学特征 ,探讨职业相关因素。 [方法 ]对 6 17名铸造工人进行背部骨科体检和疼痛测量。 [结果 ]清理和造型工种背部压痛阳性率显著高于后勤组 ,OR值分别达 6 16和 11 90 ,控制性别、年龄和工龄等混杂因素后 ,OR值更为加大 ;曾有腰背痛主诉没有差异 ,但与目前工作有关的调整腰背痛患病率仍以清理和造型高 ,与后勤比OR值在 2倍左右。造型工疼痛诱因以过度用力、重复劳动和不良姿势为主 ,共占 88 4%。腰背疼痛强度多为中等度。 [结论 ]静态弯腰作业和重体力弯腰作业与腰背痛患病率密切相关 [Objective] To describe the epidemiological characteristics of low back pain in foundry workers and to explore occupational factors. [Method] Sixty-seven foundry workers were examined with back orthopedics and pain measurement. [Results] The positive rates of back tenderness in cleaning and modeling workers were significantly higher than those in the logistics group, with OR values ​​of 6 16 and 11 90, respectively. After controlling for gender, age and length of service, the odds ratio was even higher. There was no difference in the main complaint, but the prevalence of low back pain associated with current work was still high in cleanup and styling, with an OR of about 2 times that of logistics. Modeling pain incentive to excessive force, repetitive work and bad posture-based, a total of 88 4%. Lower back pain intensity and more moderate. [Conclusion] There is a close relationship between static bending work and heavy bending work and the prevalence of low back pain
