Municipal employees' cardiovascular diseases and occupational stress factors in Finland.

The occupational stress factors related to specific cardiovascular diseases were studied by a questionnaire mailed to 6213 municipal employees aged 45 to 58 years, (response rate 85%) and by a specific job analysis of certain municipal occupations. The highest prevalences of self-reported chronic hypertension were found among male transport workers (19%), technical supervisors (19%) and auxiliary workers (15%), as well as among female domestic helpers (18%) and auxiliary workers (18%). Among men the prevalence of coronary heart disease varied from 9% for dump workers to 0% for dentists (mean 5%) and among women from 4% for kitchen supervisors to 0% for physicians (mean 3%). In the work profile groups with the highest rates of reported, specific cardiovascular diseases, the stress factors of women's work (domestic help and auxiliary work) were high energy demands, heavy dynamic and static work with high application of strength, poor postures, and uncomfortable climatic conditions. These stress factors were also typical among men doing auxiliary work. Other common stress factors among men included sensory-motor work done alone in static, monotonous sitting postures, exposured to vibration, drafts, and continuous alertness of the senses (transport work) and to processing and organization of information together with time pressure linked to decision-making and the need for accurate sensory perception (technical supervision work).
