title: Associations of sleep problems and recent life events with smoking behaviors among female staff nurses in Japanese hospitals.
abstract: For the purpose of examining the relation of sleep problems and other possible correlates with smoking among staff nurses in hospitals, the cross-sectional data of a self-administered questionnaire survey for 522 Japanese female staff nurses were reanalyzed. Registered nurses or licensed practical nurses were 82%, while nursing assistants were 18%. The prevalence of current smoking (PCS) was 29%, being higher than that in the general population of Japanese women. The current smokers exhibited a high tendency toward tobacco dependence. Multivariate analyses revealed that PCS was associated with recent frequent night shifts and a large amount of support from coworkers, while the association of a large amount of job control and a feeling of light overnight sleep with PCS was also suggested. The tobacco-dependent tendency was associated with recent life events and the presence of insomnia. It is possible that smoking is a countermeasure against sleepiness caused by the disadaptation to shift-work, or that tobacco-intake pharmacologically disturbs sleep. For decreasing PCS in staff nurses, further research should focus on the relation of smoking with their sleepiness and shift-working system, and also on the process in which major life events develop smoking behaviors.
