[Occupational stress effects on work ability in chemistry workers].
OBJECTIVE
Investigating the status of work ability and occupational stress in 1030 chemistry workers at levels of chemical materials and explore their relationship and influence factors (481 workers of study group, 549 workers of control group).


METHODS
Work ability and occupational stress were measured with the work ability index (WAI) and occupational stress questionnaire (OSQ). The risk factors of work ability decline were evaluated.


RESULTS
WAI and OSQ scores scores are significantly different between study group and control group (P < 0.01), and work ability correlated inversely with occupational stress (P < 0.01). The WAI scores are reducing with a higher of the OSQ. The work ability of chemistry-workers became lower with the increasing of age. Variables that influence work ability included the factors of disorder of musculoskeletal function (OR = 2.884), assessment of the current health (OR = 2.651), the diseases (OR = 2.498), emotion status (OR = 2.407), physical load (OR = 1.254) and lack of exercise (OR = 1.956).


CONCLUSIONS
The stress levels and stress factors had affected work ability in chemistry-workers, and it was suggested that the findings could be helpful for the measures protecting and promoting of work ability on the health of workers.
