冲焊作业工人骨密度调查研究

目的 调查冲焊作业工人骨密度，研究高温作业对工人骨密度的影响。方法 采用美国GE Lunar公司生产的Prodigy双能X线骨密度仪测定男性冲焊作业工人骨密度（BMD），同时以男性健康体检者作为对照，用自制的问卷调查表记录受试者生活习惯、饮食、运动，记录慢性疾病史、父母骨折病史等，测量身高、体重。按5岁为1年龄组分组，分别对各组骨密度进行分析。结果 两组BMD随年龄增加而降低，各年龄段冲焊作业工人骨密度低于对照组男性，差异有统计学意义(P<0.05)。结论 冲焊作业高温环境对骨密度有影响，是OP的危险因素，应注意冲焊作业工人OP的防治工作。

Investigation of bone mineral density in punching and welding workers.

Objective To investigate the bone density of the punching and welding workers, and to study the effect of high temperature on bone mineral density of the workers. Methods Bone mineral density (BMD) of the punching and welding male workers was detected using the Prodigy dual energy X-ray absorptiometry (GE Lunar, USA). Meanwhile, healthy male volunteers were as controls. The living habits, diet, and exercise of the subjects were investigated using self-made a questionnaire. The history of chronic disease and parent fracture were recorded. Height and weight were measured. All the subjects were divided into different groups according to a 5-year range. BMD was analyzed among the groups. Results BMD in the two groups decreased with increasing age. BMD of the punching and welding workers was lower than that in normal males in each age group, and the difference was statistically significant (P<0.05). Conclusion High temperature welding operation affects BMD. It is a risk factor for osteoporosis (OP). We should pay attention to the prevention and treatment of OP in punching and welding workers.
