A health promotion programme for oil refinery employees: changes of health promotion needs observed at three years.
The main aim of this three-year follow-up study was to evaluate the long-term effects of a workplace health promotion intervention programme offered by the Neste Oyj corporation's occupational health service. Another aim was to study factors associated with changes in health promotion needs. These were assessed using information obtained by means of questionnaires and laboratory measurements. The target areas assessed were physical activity, musculoskeletal problems, dietary habits, obesity, blood pressure, serum lipids, smoking, quality of sleep and mental well-being. Participants from one oil refinery were offered special health promotion counselling, while those from the other oil refinery studied received only their personal results, written information and instructions. Evaluation of the changes in needs was mainly based on comparison of the results of two examinations performed with an interval of three years. Effects of special health promotion counselling were observed in the target area of physical activity. Elimination of certain health promotion needs was seen in both groups in all of the target areas. The most extensive changes were seen in the target areas of musculoskeletal symptoms, dietary habits, blood pressure and mental well-being. Basic education, occupational status and age-group, as well as the value of tending health were frequent variables explaining the reduction in the need for health promotion activities. Worker participation in health promotion counselling activities provided by occupational health services can be high, as in this study in which the participation rate was 90% and the drop-out rate during the three years only 10%.
