Betriebliche Gesundheitsförderung: Einfluss gesundheitsfördernder Maßnahmen auf die körperliche Aktivität und Arbeitszufriedenheit von Beschäftigten eines Kommunalverbandes n NRW

Introduction: Demografic change and the digitization require target group-specific action in occupational health management. Increased sedentary activities and inac-tivity at the workplace are omnipresent and can be reduced with health programs that promote physical activity to improve the performance and job satisfaction of employ-ees. The influence of workplace interventions on job satisfaction is still unclear. The aim of the present study was to survey selected health parameters at two measure-ment times of two pedometer interventions and to determine the effects on job satis-faction. Method: Two interventions with pedometers were conducted in the period from June to September 2017 (A) and November to February 2018/2019 (B). As part of a virtual journey as a measure in the workplace health promotion of a company, anthropomet-ric data, blood pressure, daily step counts and data on subjective physical activity, sedentary behavior, health status, job satisfaction, motivation and company offers were collected by means of questionnaires. A total of 769 subjects participated in the first (A) and 1333 subjects in the second (B) study. On average, participants were 44.6 (A) and 43.0 (B) years old, the waist circumference was 89.1 (A) and 87.5 cm (B), and employees walked an average of 9467.3 (A) and 9246.1 (B) steps/day. Results: Anthropometric data revealed significant reductions in weight by 2.1 kg, BMI by 0.6 kg/m², and waist circumference by 3.1 cm in intervention A. In intervention B, waist circumference decreased significantly by 2.8 cm as well as BMI by 0.1 kg/m². In intervention B, systolic (by 2.5 mmHg) and diastolic (by 3.1 mmHg) values decreased - whereas in the first intervention, only the diastolic value decreased by 3.5 mmHg. Regarding step counts, no changes were observed in the first intervention; in the sec-ond intervention, an improvement of 437 steps/day and a decrease of 1241 steps/day in the daily step count of active participants (>10,000 steps/day). Subjective physical activity and sedentary behavior did not change significantly in either intervention. Re-garding health status, the psychological dimension decreased in the first campaign and increased in the second campaign. For motivation, the introjected (A) and intrinsic (B) dimensions increased. There were no changes in job satisfaction, but there were significant differences from the norm. Correlations of various health parameters with job satisfaction could not be determined. Discussion: The heterogeneous nature of international studies makes it clear that there are still very few consistent results available. Studies on job satisfaction require a long period of investigation in order to achieve meaningful effects. Scientific studies in the workplace setting in particular require great flexibility in study design. This in turn makes it difficult to compare the studies with one another. However, the com-pany-specific study requirements are also necessary in order to reach the target group and to create acceptance. Further studies, if possible, with control groups within a company, are necessary to better describe the data situation.
