摘　　要：目的研究化工系统工人疲劳和工作能力之间的关系,为有效预防疲劳发生、提高工作能力提供理论依据。方法采用疲劳量表和工作能力指数法(WAI)对976名化工工人的疲劳度和工作能力进行测试,同时采用统一自制量表调查所有研究对象的一般情况、不良工作环境因素、劳动负荷、工作因子等。结果未婚工人的疲劳度比已婚工人和其他婚姻状况工人低,其工作能力得分比已婚工人高,差别均有统计学意义(P<005);脑力劳动型工人的疲劳度比体脑混合型工人比低,其工作能力得分比体力劳动和体脑混合型工人高,差别均有统计学意义(P<005);与无疲劳组的工人比较,低、中、高度疲劳工人的工作能力均较低,差别有统计学意义(P<001);疲劳与工作能力呈负相关关系,相关系数为-0499(P<001);多因素分析表明,在控制了其它因素的影响后,疲劳是工作能力的危险因素。其OR值为4005(95%CI=259～620)。结论在化工系统中,疲劳是影响化工工人工作能力的重要因素,工人的疲劳度越高,其工作能力越低。Objective Explore the relationship between fatigue and work ability in 976 chemistry workers. Methods A test of fatigue and work ability was carried out with fatigue scale and work ability index (WAI) for 976 workers, other influence factors of the work ability (such as work environment, labor load, job factors) were investigated with questionnaire. Results ①The frequency of fatigue of the unmarried workers was significantly lower than that of the married workers and other marital status workers, while the score of WAI of the unmarried was significantly higher than that of those( P<0.05); ②the frequency of fatigue of the mental workers was significantly lower than that of the mixed physical and mental workers, while the score of WAI of the mental workers was significantly higher than that of physical workers and mixed physical and mental workers ( P<0.05); ③compared with the workers free of fatigue, the other workers had lower WAI scores; ④the fatigue score correlated negatively to the WAI score (r=-0.499,P<0.01); ⑤Cumulative odds model analysis showed that after controlling the other risk factors, fatigue was an important risk factor of work ability (OR =4.005). Conclusions Fatigue has affected work ability in chemistry workers, the frequency of fatigue is higher, the score of WAI is lower.
