Background
: In modern industrial society, the complexity and diversity of social structure has deeply influenced job stress, and thereby threatens mental health of jobholders more than ever. Therefore, the purpose of this study was to examine the effect of job stress in jobholders on propensity of anxiety.

Methods : Initially, 235 jobholders living in Cheonan, Asan or Seoul, from May to June 2003, were the subjects of this questionnaire. Only 233 jobholders were evaluated due to inadequate responses from two subjects. The questionnaire was made up of three contents: socio-demographic characteristic, Extended Karasek questionnaire for evaluation of job stress, and the Korean version of Goldberg anxiety scale for evaluation of anxiety. The data were analyzed by chi-square test and multiple logistic regression analysis.

Results : Univariate analysis of propensity to anxiety showed a statistical significance on age, monthly income and job characteristics. Moreover, in terms of multivariate analysis, in accordance with age, 40 to 49 (OR: 6.1), showed the highest odds ratio of propensity to anxiety, followed by 30 to 39 (OR: 5.2) and 10 to 29 (OR: 5.4). In job characteristics, high strain group (OR: 3.7) showed highest odds ratio, but neither low strain group nor active group revealed any statistical significance. In monthly income, there was no statistical significance.

Conclusion : Job stress in jobholders and propensity to anxiety was positively associated; especially, the more stress jobholders got, the higher propensity to anxiety was.

Background
: The accuracy and efficiency of a job performed by hospital employee can be linked directly with patients' health and life. It is considered that their irregular work and stress are relatively high as compared with other workplaces. In this article we tried to look into how job stress, working environment and factors of life- style influence sleep problems in hospital employees.

Methods : This research was conducted among 248 workers of a hospital in Busan on April, 2002. Sleep problems were categorized into insomnia, sleep deprivation, daytime sleepiness and snoring on the basis of the factor analysis of 11-item questions. The job stress was proposed by Karasek, etc., and measured by 14-item modified questions. The statistical analysis was conducted using Chi-square test and multiple logistic regression analysis.

Results : Statistically insomnia, sleep deprivation and daytime sleepiness showed a significant increase in women (OR:2.1/2.69/3.16) and shift workers (OR:4.67/ 3.28/1.98) and snoring showed a significant increase in obesity (OR:5.0) and smokers (OR:2.34).

Conclusion : This research showed that many hospital employees perceive sleep disorders as critical. Especially, work shift seemed to be an important risk factor for sleep disorders.
