[Study on relationship between fatigue and work ability in chemistry workers].
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
(1) The 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); (2) the 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); (3) compared with the workers free of fatigue, the other workers had lower WAI scores; (4) the fatigue score correlated negatively to the WAI score (r = -0.499, P < 0.01); (5) Cumulative 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.
