Association between occupational stressors and type 2 diabetes among Chinese police officers: a 4-year follow-up study in Tianjin, China

Abstract

Several aspects of stressors were independent predictors of T2DM in a prospective cohort study in Tianjin, China. This practical information can be applied to the development of psychological interventions against T2DM.

Increased risk of nonalcoholic fatty liver disease with occupational stress in Chinese policemen

“…And a cohort study demonstrated that occupational stress was an independent predictor of diabetes. [11,35] Additionally, NAFLD is a hepatic manifestation of MetS (i.e., associated with those traditional risk factors). [32,36,37] Thus, we further analyzed the association between occupational stress and NAFLD after adjusted MetS-related factors.…”

“…[9,11] A total of 6559 male police officers (aged 20–60 years) participated in the study; they received free health examinations, and completed the OSI-R questionnaire and interviewer-administered questionnaires. Among them, 4192 participants were excluded based on the following criteria: 408 did not complete the OSI-R and self-designed questionnaires at baseline; 295 had missing ultrasound scanning data; 981 had a history of or concurrent alcohol abuse (more than 30 g/d for males) [12] ; 362 were using steatohepatitis medication; 2146 had been diagnosed with NAFLD, chronic hepatitis B or C, autoimmune hepatitis or other liver diseases at the beginning of the study.…”

“…Fasting blood samples were obtained via venipuncture by well-trained clinical nurses from 8 am until noon, and were sent to a laboratory in police hospital <60 min after collection. [11] Biochemical values including alanine aminotransferase (ALT), total cholesterol (TC), triglycerides (TG), high- and low-density lipoprotein cholesterol (H/LDL-C), and fasting plasma glucose (FPG) were tested using an Automatic Biochemical Analyzer (TBA-120FR, Toshiba Corp, made in Shanghai, China) with standard laboratory procedures. [9] …”

“…[13] In particular, the OSI-R questionnaire used in the present study was confirmed to have good reliability and internal consistency for Chinese policemen (Cronbach alpha: OSI-R = 0.883, ORQ = 0.908, PSQ = 0.934, and PRQ = 0.909). [11] …”

“…[10] The Occupational Stress Inventory-Revised (OSI-R) questionnaire, which is confirmed to have a good reliability and validity in different occupational populations, has been widely used to assess the degree of occupational stress, and to analyze the relationship between occupational stress and healthy disorders. [11] Thus, our study was established to examine the relationship between occupational stress based on OSI-R scores and the incidence of NAFLD in a police cohort in Tianjin, China.…”
