Overview

Purpose To explore the relationship between occupational stressors and the incidence of type 2 diabetes mellitus among police officers. Methods Baseline data were collected from policemen who completed the Occupational Stress Inventory-Revised (OSI-R) questionnaire, a self-designed questionnaire, and underwent free clinical measurements at the Medical Center of Police Hospital in Tianjin, China, in April 2007. A total of 5811 policemen participated in follow-up with the dynamic observation of new-onset diabetes (NOD) events occurring annually between 2008 and 2011. Occupational stress was measured by the OSI-R questionnaire, which contains 14 different scales. Cox proportional hazards regression was used to calculate the hazard ratios (HR) of the incidence of type 2 diabetes mellitus (T2DM) by occupational stressors. Results A total of 3.1 % of the participants ( n  = 179) developed NOD in the follow-up period from 2008 to 2011, and the incidence rates of NOD were 0.58 % in 2008, 0.98 % in 2009, 0.52 % in 2010, and 1.01 % in 2011. Role overload (RO), role boundary (RB), physical environment (PE), interpersonal strain (IS), and physical strain (PHS) were associated with the incidence of T2DM (RO: HR = 1.574, 95 % CI = 1.071–2.372; RB: HR = 1.645, 95 % CI = 1.144–2.365; PE: HR = 2.292, 95 % CI = 1.545–3.400; IS: HR = 1.537, 95 % CI = 1.079–2.191; and PHS: HR = 1.680, 95 % CI = 1.167–2.006) after adjustment for confounding factors. A subgroup Cox regression analysis among traffic control police officers showed the specific work stressors remained robust except RO. Conclusions 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.
