化工工人工作能力变化及其影响因素研究

Study on Work Ability and Its Risk Factors in Chemical Plant Workers

目的 了解化工工人的工作能力及职业紧张状况 ,探讨影响工作能力的因素。方法 应用工作能力指数表 (WAI)和职业紧张问卷 (OSQ) ,对某市 10 30名化工工人进行调查 ,用多元 logistic回归模型评价背景因素及职业紧张因素对工作能力减退的危险度。结果 化工工人工作能力降低的主要危险因素是肌肉骨骼功能失调(OR=2 .316 )、健康状况估计 (OR=2 .0 70 )、疾病 (OR=2 .14 4 )、睡眠不良 (OR=1.5 73)、情绪激动 (OR=1.6 6 0 )、体力负荷 (OR=1.12 4 )、活动程度 (OR=1.12 7)、工作中的问题 (OR=1.12 6 )、缺乏体育锻炼 (OR=1.4 0 8)、受教育程度 (OR=2 .2 4 7)等。结论 影响化工工人工作能力减退的主要因素是紧张的生理、心理因素及受教育程度等 ,应有针对性的调整各项紧张因子 ,降低危险因素 ,增加工人的文化素养 。

Objective To investigate the status of work ability and occupational stress in chemical plant workers and to ascertain the risk factors affecting work ability. Methods 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. Results 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). Conclusion 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.
