接尘工人工作能力研究

Study on Work Ability of Dust-exposed Workers

目的了解接尘工人工作能力的变化规律。方法用"工作能力指数测量问卷"对213例健康不接尘工人(对照组)、307例接尘工人的工作能力进行测量。结果 WAI均值无论是对照组、接尘组还是尘肺组均随着年龄的增长而下降,不同性别间差异无统计学意义。对照、接尘和尘肺组间差异有统计学意义(P<0.01),其中接尘组显著低于对照组,尘肺组又显著低于接尘组,进一步分析发现接尘组中的石棉组和煤尘组的WAI低于对照组(P<0.01),而矽尘组与对照组间差异无统计学意义。结论早在尘肺发生前,接尘工人的工作能力已显著下降。应该尽早采取措施,保护接尘工人的工作能力和身体健康。

Objective To analyze the work ability variation of dust-exposed workers.Methods Work ability of 213 healthy workers with no dust exposure（control group） and 307 dust-exposed workers was assessed by ’Work Ability Index’（WAI） with questionaires.Results The mean level of WAI decreased with age in all groups.There was no significant difference in genders.The differences of WAI mean level between 3 groups were statistically significant（P〈0.01）,in which,of control group was lower than that of dust-exposed workers,of dust-exposed workers was lower than that of pneumoconiosis patients（P〈0.01）.There was no statistical difference between pneumoconiosis patients and the control.Conclusion It suggested that the work ability of dust-exposed workers had been decreased before pneumoconiosis developed.In order to protect the work ability and health of dust-exposed workers,measures should be taken early
