Relationship between occupational stress and type 2 diabetes mellitus / 中华劳动卫生职业病杂志

<p><b>OBJECTIVE</b>To investigate the association of occupational stress and related factors with type 2 diabetes mellitus (T2MD).</p><p><b>METHODS</b>In case-control study, a questionnaire survey was conducted in 201 T2MD patients and 201 controls, who were selected from the staff members of organizations, enterprises, and institutions in Ningxia Hui Autonomous Region, China according to inclusion and exclusion criteria, to acquire the information on general condition and occupational stress. These subjects also underwent physical examinations and blood biochemical analyses.</p><p><b>RESULTS</b>The T2MD group had significantly higher total occupational stress score, as well as the scores on such factors as workload, interpersonal relationship, and home/work balance than the control group (P < 0.01). After adjustment for age, gender, education level, smoking, and drinking, the odds ratios for T2MD were 2.538 and 3.075 in the people with moderate and severe stress, respectively, compared to those with mild stress. The risk factors for T2MD included drinking, family history of diabetes, waist circumference, triglyceride level, and total occupational stress score, while the protective factors included educational level and high-density lipoprotein level.</p><p><b>CONCLUSION</b>Occupational stress is associated with the incidence of T2MD; the higher the degree of stress, the greater the risk of T2MD. Relevant measures should be taken to reduce the occupational stress or improve the ability of workers to cope with the stress, thus decreasing the incidence of T2MD among occupational population.</p>
