OBJECTIVE Little is known about the relationship between changing psychosocial work conditions and type 2 diabetes. We determined whether changing work stressors and coping resources affect the risk of type 2 diabetes.

RESEARCH DESIGN AND METHODS In this prospective cohort (2003–2014) of 3,740 workers without diabetes (OHSPIW [Occupational Health Study of Petroleum Industry Workers]), participants completed an evaluation of work-related stress and coping resources and type 2 diabetes diagnosis at baseline and 12 years follow-up (two waves). The changes in work stressors and coping resources were measured with the Occupation Stress Inventory–Revised and the Instrument for Stress-Related Job Analysis (Version 6.0). Type 2 diabetes was diagnosed on the basis of an oral glucose tolerance test supplemented by physician report.

RESULTS Increased task stressors (relative risk [RR] 1.57 [95% CI 1.03–2.63]) and decreased coping resources (RR 1.68 [95% CI 1.02–2.83]) were associated with risk of type 2 diabetes. The main risk factors were increased role overload, increased role insufficiency, increased physical environment stressors, decreased self-care, and decreased rational coping. Increased coping resources also had a buffering effect on increased task stressors and type 2 diabetes.

CONCLUSIONS Changes in work stressors and coping resources have an influence on the risk for type 2 diabetes, highlighting the importance of preventive measures against adverse psychosocial work conditions and reduced coping resources for diabetes prevention in the workplace.

研究设计和方法在此前瞻性队列（2003年至2014年）中，有3,740名无糖尿病的工人（OHSPIW [石油工业工人的职业健康研究]），参与者完成了与工作相关的压力和应对资源的评估，以及基线时的2型糖尿病诊断和12年的随访（两次浪潮）。使用修订后的职业压力清单和压力相关工作分析工具（6.0版）来衡量工作压力源和应对资源的变化。2型糖尿病是根据口服葡萄糖耐量试验和医师报告补充诊断的。

结果增加任务压力（相对风险[RR] 1.57 [95％CI 1.03–2.63]）和减少应对资源（RR 1.68 [95％CI 1.02–2.83]）与2型糖尿病的风险相关。主要危险因素是角色超负荷增加，角色功能不足增加，身体环境压力增加，自我护理减少和理性应对减少。应对资源的增加也对增加工作压力和2型糖尿病具有缓冲作用。

结论工作压力和应对资源的变化对2型糖尿病的风险有影响，突显了预防不利的社会心理工作条件的预防措施的重要性，以及减少工作场所预防糖尿病的应对资源的重要性。
