| Objective: To know the influence factors of occupational stress and diabetes mellitus(DM). To investigate the effects of occupational stress and working conditions on DM in Tianjin male police officers. To provide epidemiology basis for screening and preventing and controlling DM high-risk groups in male police officers early.Methods: 1.6456 Tianjin police officers were invited to a study,which aimed to investigate the status of occupational stress and DM, logistic regression analysed the risk factors of occupational stress and DM. After controlling confounding variables, the relationship between occupational stress and DM were discussed. 2.Eliminating 381 who diagnosed DM in 2007, the rest of 6075 Tianjin police officers were invited to a prospective cohort study, DM incidence was observed in the follow up. Cox proportional hazard regression analysis was used to calculate the hazard ratios(HR) of DM predicted by occupational stress status and working conditions, DM high-risk groups were screened in police officers.Results: 1.The influence factors of occupational stress in Tianjin male police officers Compared to 21 ~ age group, the risk of occupational role stress of 31 ~, 41 ~ age group were 1.36, 1.33 times; the risk of occupational role stress of traffic police was 1.47 times that of organ police; the risk of occupational role stress of work more than eight hours was 1.48 times that of normal working hours in police men(P < 0.001). With the increasing of age, the risk of personal strain was smaller; compared to the male police officers without outdoor service, the OR(95% CI) of personal strain in outdoor work was 1.38(1.18 ~ 1.62); the risk of personal strain in work more than eight hours of male police officers was 1.37 times that of normal working hours(P < 0.001). Compared to 21 ~ age group, the OR(95% CI) of personal resources in 41 ~, 51 ~ age group were 0.75(0.60 ~ 0.94) and 0.73(0.55 ~ 0.97); compared to the malepolice officers without outdoor service, the OR(95% CI) of personal resources in outdoor work was 1.67(1.37 ~ 2.05). 2.The influence factors of DM of police officers in Tianjin Compared to the 21 ~ age group in police officers, the risk of DM in 41 ~, 51 ~ age group were 5.10 and 8.15(P < 0.001); compared to undergraduate below of police officers, undergraduate and above was DM protection factor, the OR(95% CI) was 0.77(0.61 ~ 0.97); the family history of DM, dyslipidemia, hypertension were the risk factors for DM, the OR(95% CI) were 1.97(1.58 ~ 2.46), 2.13(1.69 ~ 2.68), 1.69(1.34 ~ 1.34), respectively. The risk of the DM of traffic police and security police was about 1.5 times that of organ police. After controlling confounding factors, the risk of DM of the police men with middle levels of occupational stress was 1.78 times that of the moderate group(P < 0.05). 3.Impact of occupational stress and working conditions on DM in male police officers During the follow up from 2008 to 2011, 179(3.1%) developed DM 2.61 years(median) later. The HR(95% CI) of traffic police was significantly higher than other kinds of police was 2.89(2.12 ~ 3.93). Compared to the moderate group, the HR(95% CI) of police offices with absence of occupational role stress, high level of occupational role stress, middle and high levels of personal strain were 3.12(1.81 ~ 5.38), 1.97(1.34 ~ 2.91), 1.66(1.12 ~ 2.44) and 2.57(1.34 ~ 4.92), respectively. After redefined the risk factors, compared with other polices, the HR(95% CI) of traffic polices with the lack of occupational role stress, middle and high level of occupational role stress, middle and high levels of personal strain were 4.62(2.39 ~ 8.90)、2.44(1.65 ~ 3.60)、3.30(2.20 ~ 4.94)、3.11(1.93 ~ 5.03)、4.48(1.83 ~ 10.98).Conclusion: Police classification and high work intensity and outdoor work were the risk factors of the occupational stress in male police officers, age was also closely related to occupational stress. Occupational stress and working conditions played an important role in incident of DM. The traffic police and non- moderate occupational stress levels were its independent risk factors. |
