||Job stress, social support at work and insomnia in Japanese shift workers
||Dec. 2001, Vol.30, No.1-2, p.203-209. 27 ref.
||To study the relationship between psychological job stress and insomnia in shift workers, a self-administered questionnaire concerning job stress, sleep, depressive symptoms and lifestyle factors was submitted to a sample of 530 rotating shift workers in an electric equipment manufacturing company. Perceived job stress was assessed using the Japanese version of the Job Content Questionnaire. Overall prevalence of insomnia was 37.8%. Logistic regression analyses showed that lower social support at work was significantly associated with a greater risk of insomnia than the higher social support (odds ratio (OR) 2.5). Higher job strain with lower social support at work increased the risk, compared to lower strain with higher support at work (OR 1.5). The findings suggest the low social support at work is independently associated with insomnia in shift workers.
