OBJECTIVES: This study sought to provide evidence for the relationship between health risks and selfreported absenteeism and presenteeism. METHODS: A cross-sectional analysis of 496 employees of an electric company was conducted. Participants responded to a self-questionnaire including the assessment of 7 health risks (obesity, current smoking, problem drinking, lack of exercise, chronic disease, depressive mood, high stress) and the Work Productivity and Activity Impairment - General Health Questionnaire (WPAI-GH). Logistic regression analyses were used to determine the significance of health risks on work impairment. RESULTS: As a result of the analysis of all the participants, problem drinking (absenteeism) and high stress (absenteeism and presenteeism) were significantly associated with work impairment. In the analysis of a sub-group, current smoking (presenteeism), lack of exercise (absenteeism), and high stress (presenteeism and absenteeism) were significantly associated with reduced productivity among the blue-collar workers. However, the analysis of the white-collar workers showed no significant relationship between health risks and work impairment. CONCLUSIONS: This investigation suggests that employees who have more health risks will experience more absenteeism and presenteeism than employees with fewer risks, and this association is affected by employment type.

3.Methodological Review of Cost Effectiveness Analysis of Cancer Screening.
Korean Journal of Epidemiology 1998;20(1):13-31
The role of economic evaluation for medical services can be summarixed as providing objective criteria for rational bgudget allocation. With medical and epidemiologial studies, cost effectiveness analysis of cancer screening will provide evidence for allocating more financial resources for cancer screening. This study reviewed comprehensive literature of cancer screening for cervical cancer and breast cancer. Through the extensive review of the literature, I suggest crucial issues of cancer screening and checkpoints in designing costeffectiveness analyses of cervical and breast cancers. The issues of cervical and breast cancer screening include ages of starting and terminating mass screening, screening interval and frequency, false positive rate, false negative rate, analytical models, and sensitivity analysis. In addition, cost effectiveness analysis of breast cancer should consider effects of screening methods-self examination, clinical examination, and mammography-that varies across different nations on cost effectiveness ratio. Study results of most issues would be relevant for performing cost effectiveness analysis of cancer screening in Korea. However, difference in incidence rate, medical fees and reimbursement by insurance across nations should be considered in designing cost effectiveness analysis.
