Abstract:
Objective:To investigate the influencing factors for depression among workers in a petrochemical enterprise and the association of occupational stress and occupational environment with depression, and to provide a scientific basis for the improvement of mental health and the prevention and treatment of depression among workers in petrochemical enterprises.Methods:A cross-sectional study was performed in March 2018, and cluster sampling was used to select 1888 workers from a petrochemical enterprise in Liaoning Province, China for a questionnaire survey. A total of 1888 questionnaires were collected, among which there were 1521 usable questionnaires, with an effective recovery rate of 80.56%. The general status of the workers in this petrochemical enterprise was investigated, and Center for Epidemiologic Studies Depression Scale (CES-D) , Effort-Reward Imbalance (ERI) , and Perceived Work Environment (PWE) were used to evaluate depression, occupational stress, and occupational environment. Constituent ratio was used to describe the distribution of different demographic features, work conditions, and lifestyles among the workers in this petrochemical enterprise. One-way analysis of variance and the t-test were used to compare the scores of depressive tendency between the workers with different features. Pearson correlation analysis was used to investigate the correlation of occupational stress and occupational environment with depression. Multivariate hierarchical regression analysis was used to investigate the influencing factors for depression.Results:The score of depression tendency was 18.94±9.21 in the workers in this petrochemical enterprise, and the incidence rate of depression symptoms was 59.8% (909/1521) . The workers who were aged <35 years, lived alone or in widowhood, or had an income of ≤4000 yuan tended to have a high score of depression tendency. And ordinary workers, oil-refining workers, workers with night shift and non-fixed shift, and workers with a lack of physical exercise and low sleep quality tended to have a high score of depression tendency ( P<0.05) . The dimensions of extrinsic and intrinsic efforts of occupational stress and severity of occupational environment were positively correlated with depression ( r=0.254, 0.242, 0.274, P<0.01) . And the dimension of reward was negatively correlated with depression ( r=-0.348, P<0.01) . The multivariate hierarchical regression analysis showed that occupational stress and occupational environment had a marked predictive effects on depression, with an explained variance of 18.4% and 12.1%, respectively. Conclusion:There is a high level of depression tendency among workers in petrochemical enterprises, and demographic features, work conditions, lifestyle, occupational stressors, and occupational environment factors are influencing factors for depression.
