Effect of occupational stress and effort-reward imbalance on sleep quality of people's policeman

Abstract

To explore the effect of occupational stress and effort-reward imbalance on sleep quality of people's police. A cluster sampling survey of sleep quality and occupational stress correlated factors was conducted on 287 police from a city public security bureau by questionnaires in May, 2011; the relationship between sleep quality and occupational stress correlated factors was analyzed by one-way ANOVA and multivariate non-conditional logistic regression using effort-reward imbalance model (ERI) and demand-control-support model (DCS). And the subjects were divided into high tension group and low tension group using the 1.0 of ERI and DCS coefficients as the boundary. The sleep quality score of shift work police was higher than day work police (11.95 ± 6.54 vs 9.52 ± 6.43, t = 2.77, P < 0.05).In ERI model, the sleep quality score in high tension group was higher than low tension group (14.50 ± 6.41 vs 8.60 ± 5.53, t = -5.32, P < 0.01), and in DCS model, the sleep quality score in high tension group was also higher than low tension group (13.71 ± 6.62 vs 9.46 ± 6.04, t = -3.71, P < 0.01).For the regression analysis of ERI model as an argument, sex (OR = 3.0, 95%CI:1.16-7.73) , age for 30-39 years (OR = 3.48, 95%CI:1.32-9.16) , intrinsic effort (OR = 2.30, 95%CI:1.10-4.81) and daily hassles (OR = 2.15, 95%CI:1.06-4.33) were risk factors of low sleep quality, and reward (OR = 0.26, 95%CI:0.12-0.52) was the protective factor.For the regression analysis of DCS model as an argument , age for 30-39 years (OR = 2.55, 95%CI:1.02-6.37) , depressive symptom (OR = 2.10, 95%CI:1.14-3.89) and daily hassles (OR = 3.25, 95%CI:1.70-6.19) were risk factors of low sleep quality.While the ERI model and the DCS model were analyzed simultaneously, sex (OR = 3.03, 95%CI:1.15-7.98) , age for 30-39 years (OR = 3.71, 95%CI:1.38-9.98) and daily hassles (OR = 2.09, 95%CI:1.01-4.30) were the risk factors of low sleep quality, and reward (OR = 0.22, 95%CI:0.10-0.48) was the protective factor. Occupational stress and effort-reward imbalance affected the sleep quality to people's policeman.
