目的评价苯系有机溶剂促进职业人群老龄化的作用。方法以１８７名接触有机溶剂的工人为接触组，１６１名制衣厂工人为对照组，进行工作能力指数、生理指标及生物学年龄的调查测试。结果发现工作能力指数随着年龄的增长呈下降趋势，低浓度有机溶剂接触组工作能力指数的下降较对照组为快；４５岁以上，接触组工人的工作能力指数有较明显的下降，对照组无改变；女性接触组工人的生物学年龄与日历年龄相比，增长１．８４岁。结论低浓度苯系有机溶剂具有促进职业人群老龄化的轻微作用。
Objective To evaluate the effect of benzene series organic solvents on the aging of occupational population. Methods Totally 187 workers exposed to organic solvents were used as the contact group and 161 garment factory workers were used as the control group. The working capacity index, physiological indexes and biological age were investigated. The results showed that the working ability index decreased with age, and the working ability index of the low-concentration organic solvent exposure group decreased more rapidly than that of the control group. The working ability index of the exposed group workers was obviously decreased after 45 years of age. No change. The biological age of women exposed workers increased by 1.84 years compared with the calendar age. Conclusions Low concentrations of benzene-based organic solvents have the slight effect of promoting the aging of occupational groups.
