Official title
Effects of a Sedentary Behaviors at Work on Health in Emergency Medical Dispatchers and CODIS Operators
Overview
The purpose of the study is to study changes in sedentary behavior following a behavioral intervention (sit-and-stand desk, and cycloergometer)
Detailed description
Each emergency medical services dispatcher and each firefighter participates in the study for three days. A normal working day from of 12h is compared to: (i) a working day during which the participants have to get up at least 5 min/hour (sit-and-stand desk), (ii) a working day during which they can use a cycloergometer installed under the desk. Conditions will be random using Latin Square design with stratification between sequences cross-over design on occupation (EMD vs. firefighters).
The heart rate variability (measured using Zephyr®), the electrodermal activity (Empatica® E4), the level of physical activity (Actigraph®) as well as the blood sugar (Freestyle®) will be measured continuously during the 12 hours of work and the night after except for Actigraph® and Freestyle® device that will be let one week. Blood and saliva samples will be collected on each working day, at the beginning and end of the day i.e. two measures for blood samples, and every three hours i.e. 5 measures for saliva sampling. Participants will have to complete a detailed questionnaire to identify the particular events (vital emergencies, etc.) that may influence the parameters measured.
Participants will be asked to answer a general questionnaire once at the start of the study that will cover different aspects:
* Sociodemographic, * Visual analogue scale (VAS) related to psychosocial factors : stress at home, burnout / burnout, decision latitude / autonomy at work, psychological demands at work (workload), support from the hierarchy, support from co-workers, family support, job satisfaction with regard to effort, commitment to work, addiction to work, quality of life, need for psychological support, * Eating habits.
They will then have to answer a short questionnaire at the beginning and at the end of each measurement day. It will cover different aspects:
* Four VAS (stress level, fatigue, anxiety, mood), * Physical activity and sedentary lifestyle (number of hours of physical activity and sitting during the last 24 hours), * Daily consumption (tobacco, alcohol, cannabis, coffee, tea).
Interventions
- Behavioral Control
A normal working day from of 12h - Behavioral Sit-and-stand desk
a working day during which the participants have to get up at least 5 min/hour - Behavioral Cycloergometer
a working day during which they can use a cycloergometer installed under the desk
Primary outcome measures
- Sedentary behavior [Time frame: 12 hours of work corresponding to the control condition]
- Sedentary behavior [Time frame: 12 hours of work corresponding to the sit-and-stand desk condition]
- Sedentary behavior [Time frame: 12 hours of work corresponding to the cycloergometer condition]
Secondary outcome measures (12)
- Sedentary behavior [Time frame: one-week (168 hours) sit-and-stand desk cycle]
- Sedentary behavior [Time frame: one-week (168 hours) control cycle]
- Sedentary behavior [Time frame: one-week (168 hours) cycloergometer cycle]
- Heart rate variability [Time frame: 24 hours record corresponding to 12 hours of work and the next 12 hours of rest]
- Electrodermal activity [Time frame: 24 hours record corresponding to 12 hours of work and the next 12 hours of rest]
- Stress at home [Time frame: 6 am, beginning of the control day]
- Stress at home [Time frame: 6 am, beginning of the sit-and-stand desk day]
- Stress at home [Time frame: 6 am, beginning of the cycloergometer day]
- Stress at home [Time frame: 6 pm, end of the control day]
- Stress at home [Time frame: 6 pm, end of the sit-and-stand desk day]
- Stress at home [Time frame: 6 pm, end of the cycloergometer day]
- Fatigue [Time frame: 6 am, beginning of the control day]
