Interventions

Current interventions as of 31/03/2021: The original intervention (doi: 10.1186/s12889-020-8291-y) was developed before COVID-19. Due to the pandemic, the institutions had to adhere to new guidelines
the workshops for the childcare workers are replaced with outdoor consultant visits in smaller groups of childcare workers
the pre and post cardiorespiratory fitness test were no longer possible to perform while still adhering to the guidelines from Danish health Authority and was therefore excluded from the protocol (and
The intervention aims to increase childcare workers’ productive work time spent in HIPA, thus improving their health. Participating childcare institutions will be randomised to either an intervention

Design outcomes

Primary

MeasureTime frame
Current primary outcome measure as of 31/03/2021: Change between baseline and 8 weeks follow-up in relative work time spent in HIPA measured by heart rate (i.e. =60% of heart rate reserve). Previous primary outcome measure: Work time spent in moderate to vigorous physical activity measured by heart rate (i.e. =60% of heart rate reserve) or accelerometers (i.e. fast walking (=130 steps/ minute), running and stair climbing) between baseline and 10 weeks follow-up

Secondary

MeasureTime frame
Current secondary outcome measures as of 31/03/2021: 1. Change between baseline and 8 weeks follow-up in sleeping resting heart rate, measured by heart rate monitors 2. Change between baseline and 8 weeks follow-up in self-perceived pain, exhaustion and energy measured using single item questions 3. Change between baseline and 8 weeks follow-up in need for recovery measured by questionnaire 4. Change between baseline and 8 weeks follow-up in self-perceived productivity measured using questionnaire 5. Incremental change in cost-effectiveness (ratio of incremental change in cost and change in work time spent in HIPA) and return on investment (indicated by return-on-investment ratio) during 8 weeks intervention from an employers´ perspective. Health-related outcomes will be determined for all participants at baseline and 8 weeks follow-up. Outcomes include height, weight, fat percentage and resting blood pressure. Physical behaviours and heart rate will be assessed by accelerometers and heart rate monitors worn over several working days. Moreover, at baseline and 8 weeks, participants will receive an electronic questionnaire, with questions concerning health status, musculoskeletal pain, fatigue, work environment, expectations and satisfaction with the intervention. For cost-effectiveness analysis, we will collect information on cost of intervention activities and cost associated with health-related productivity loss. Intervention cost will include: - Staff time: Participation of childcare workers will be assessed based on registration of attendance. - Work environments consultant time: Hours spent on preparation and delivery of the consultant visits will be retrieved from the work environment consultants delivering the consultant visits. - Consumables: Information on the cost of materials (e.g. print-outs and materials used in the Goldilocks-games) will be collected via invoices. - Overhead (e.g. telephone bills and electronics usage): 20 % of the interventio
