[Mental health, work environment, and health practices among middle-aged male workers].
A study was made on the cross-sectional relationship of the psychosocial work environment and personal health practices to mental health level among 15,639 male subjects aged 30-59 engaged in various kinds of occupations and firms. Mental health level was dichotomized by self-reported mental disorders. The psychosocial factors of work environment were conceptually constructed from the aspects of working conditions and occupational stress. Working conditions were assessed by work overload, work shifts and role in the organization. Occupational stress was measured by psychological work load and job characteristics (job demands and decision latitude). Various factors associated with positive health behavior--an index based on six parameters such as supper time, physical exercise, smoking, alcohol consumption, sleep, and weight--were examined. The prevalence of self-reported mental disorders was 17.5 per 1,000 population. Multiple logistic analysis showed that both psychological work load and health practice index have a significant independent effect on mental health levels after controlling for age and marital status. Limitations of the present study indicate a need for future longitudinal studies.
