To investigate the status of work ability and occupational stress in chemical plant workers and to ascertain the risk factors affecting work ability.
The method of cluster random sampling was adopted. Work ability and occupational stress were measured using the methods of work ability index (WAI) and occupational stress questionnaire (OSQ) in 1030 workers. The risk factors for work ability decline were evaluated.
The variables that influence work ability included disorder of musculoskeletal function (OR = 2.316), current health (OR = 2.070), diseases (OR = 2.144), poor sleeping (OR = 1.573), easy excitement (OR = 1.660), degree of movement (OR = 1.127), physical load (OR = 1.124), problem in working process (OR = 1.126), lack of exercise (OR = 1.408), and education level (OR = 2.247).
The main risk factors influencing work ability included the physiological, mental factors and the level of education. For reducing the risk factors, relevant measures should be taken to protect the work ability and promote the health of workers.
调查化工厂工人的工作能力和职业压力状况，并确定影响工作能力的危险因素。
采用整群随机抽样法。运用工作能力指数（WAI）和职业压力问卷（OSQ）对1030名工人的工作能力和职业压力进行测量。评估工作能力下降的危险因素。
影响工作能力的变量包括肌肉骨骼功能紊乱（OR = 2.316）、当前健康状况（OR = 2.070）、疾病（OR = 2.144）、睡眠不佳（OR = 1.573）、易激动（OR = 1.660）、运动程度（OR = 1.127）、体力负荷（OR = 1.124）、工作过程中的问题（OR = 1.126）、缺乏锻炼（OR = 1.408）以及教育水平（OR = 2.247）。
影响工作能力的主要危险因素包括生理、心理因素以及教育水平。为降低危险因素，应采取相关措施保护工人的工作能力并促进其健康。
