Activity Trackers @ Work

Lennefer, Thomas 29 January 2021 (has links)
Heutzutage erfüllen nur 35 % der Deutschen das empfohlene Maß an körperlicher Bewegung (Robert Koch Institute, 2015). Ein möglicher Grund für diese Inaktivität ist, dass die körperliche Betätigung am Arbeitsplatz sich in den letzten Jahren um insgesamt 28% verringert hat (Wilke, Ashton, Elis, Biallas, & Froböse, 2015). Um dieser Entwicklung entgegenzuwirken, evaluiert die vorliegende Dissertation eine mHealth Intervention bestehend aus Fitnessarmbändern und einem Online Coach, welche die Bewegung von inaktiven Beschäftigten mit Gesundheitsrisiko fördern soll. Zusätzlich wird das Occupational Health Behavior Change (OHBC) Modell als theoretische Grundlage für Veränderungen von Gesundheitsverhalten im betrieblichen Kontext entwickelt. Das OHBC Modell verbindet ein gesundheitspsychologisches Modell mit einem Modell aus dem Bereich der Arbeits-& Organisationspsychologie und stellt die Grundlage für die beiden veröffentlichten Studien der Dissertation dar. Studie I bewertet den Effekt der Intervention auf körperliche Gesundheit und arbeitsbezogenem Wohlbefinden anhand eines randomisiert kontrollierten Studiendesigns und unter Berücksichtigung von Langzeiteffekten. Beschäftigte in der Interventionsgruppe zeigten eine Verbesserung ihrer physischen Gesundheit bis zu einem Jahr nach der Intervention, jedoch wurde kein Effekt auf arbeitsbezogenes Wohlbefinden gefunden. Studie II zeigt, dass die Schrittanzahl und die Beeinträchtigung des Wohlbefindens während der Intervention verbessert werden und beantwortet weiterführende Fragen über die Effektivität der Intervention anhand von modernen statistischen Methoden. Abschließend werden die Ergebnisse der beiden Studien diskutiert und dabei die Struktur des neu kreierten OHBC Modells überprüft. Insgesamt zeigt die vorliegende Dissertation, dass Fitnessarmbändern kombiniert mit einem Online Coach eine effektive Intervention darstellen, um körperliche Aktivität, physische Gesundheit und das Wohlbefinden von Beschäftigten zu fördern. / Nowadays only 35% of the German population performs the recommended amount of physical activity (Robert Koch Institute, 2015). A reason for this inactivity might be that the amount of moderate to vigorous physical activities at work (e.g., brisk walking or moving heavy loads) has diminished by about 28% within the last decades (Wilke et al., 2015). To counteract this alarming development, this dissertation evaluates an mHealth intervention that aims to promote physical activity in the working environment. In particular, this intervention combines activity trackers with an online coach to promote physical activity among inactive employees at risk. Furthermore, this dissertation creates the Occupational Health Behavior Change (OHBC) model as a theoretical framework for changing health behavior within a work setting by combining a model of the health psychology with a model of the industrial and organizational psychology. The model functions as the basis for the two published studies of the dissertation. Study 1 evaluated the intervention by using a randomized controlled trial design and assessed long-term effects on employees’ physical health and work-related well-being. The results show that employees in the intervention group improved their physical health up to one year after the intervention whereas no effect was found for work-related well-being. Study 2 shows that the number of steps and impaired well-being were improved during the intervention and clarified several additional questions about the intervention’s efficacy by applying modern statistical methods. Finally, the findings of the studies were discussed and the theoretical structure of the newly created OHBC model was reviewed based on the studies’ results. Taken together, the overall findings show that combining activity trackers with an online coach constitutes an effective intervention for occupational health promotion with the aim of promoting physical activity, health and well-being among employees.

Vztah stravovacích návyků a znalostí o výživě u žáků devátého ročníku základních škol a návrh nutričního edukačního programu / The relationship between eating habits and nutrition-related knowledge of grade nine students of elementary schools and design of nutrition education program

Kočí, Jana January 2019 (has links)
Obesity and the number overweight of children are currently major global issues. According to the Regional Office for Europe (2006) obesity has risen three times over the last two decades worldwide. The attention is currently focused on health promotion and disease prevention among the population through comprehensive health education starting in the early age of individuals, aimed to slow down the increasing incidence of obesity and related health issues. This thesis discusses the pedagogical aspects of health, specifically the options on how to shape nutritional habits of elementary and middle school students and how to systematically deepen the required knowledge about healthy nutrition by implementation of nutrition education programs. The purpose of this study was to determine the relationships between dietary habits and healthy nutrition knowledge of grade nine students in elementary schools from the South Bohemian region in Czech Republic. A validated Nutritional survey and Nutritional knowledge quiz were designed to determine the relationship between knowledge and behavior of grade nine students from South Bohemia elementary schools. The validity of the Nutritional survey and the Nutritional knowledge quiz were tested using analytical analysis of all survey and test items and examining...
