Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary study parameters are shift work exposure, body weight and infection susceptibility. Shift work exposure will be measured with an extensive questionnaire covering the different domains of shift work, i.e. shift system, cumulative exposure and shift intensity. Furthermore, anthropometric measurements (i.e. height, weight and waist circumference) will be performed during the study to assess changes in body weight. Infection susceptibility will be defined as the development of influenza-like illness (ILI). The occurrence of ILI cases during the study period will be measured with a log (app). | — |
Secondary
| Measure | Time frame |
|---|---|
| The secondary study parameters are the potential mechanisms that link shift work to health effects on which we will focus in this study; these are sleep factors, physical activity, diet behaviors, light, vitamin D level and immunological factors. Furthermore, other parameters that may play a role in the relation between shift work and health will be measured; these are smoking, alcohol use, job satisfaction, work-life balance, general health, absenteeism and presenteeism. In addition, factors that may modify the relation between shift work and health will be measured; these are socio-demographic factors, chronotype and quality of life. | — |
