About this study
Official title: Effects of a Sedentary Behaviors at Work on Health in Emergency Medical Dispatchers and CODIS Operators
The purpose of the study is to study changes in sedentary behavior following a behavioral intervention (sit-and-stand desk, and cycloergometer)
Read the 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).

RPAQ questionnaire
The Recent Physical Activity Questionnaire (RPAQ) assesses the level of physical activity and sedentary lifestyle in adults over the past four weeks. It is divided into three parts: work and study, home and leisure, and finally, stairs and travel. It makes it possible to classify individuals into several categories, one on sedentary lifestyle (low, resistant either 3-7h/day or high or >7h/day) and one on the level of physical activity (<8.3 Metabolic equivalent of task(MET).hour/week: inactive or >8.3 MET.h/wk: active).
Measured: Once at baseline
MBI questionnaire
The Maslach Burn-out Inventory (MBI) is composed of 22 items designed to assess the three components of the burn-out syndrome: emotional exhaustion (9 items), depersonalization (5 items) and reduced personal accomplishment (8 items). The items are written in the form of statements about personal feelings or attitudes. Items are made of a 7-point scale frequency of feelings, varying from "never" to "every day". The scores for each component of the burn-out syndrome are considered separately. If desired for participant feedback, each score can be coded as low, average, or high.
Measured: Once at baseline
JDCS questionnaire
The Job Demand-Control-Support (JDCS) questionnaire of Karasek assess job demands, job control and social support through 26 items. The questionnaire measures nine items of job demands, nine items of job control and eight items of social support. Items of JDCS are scored on a four-point Likert-type scale, ranging from 1 = strongly disagree to 4 = strongly agree. Among the 26 items, five negative statements require reverse scoring. From French data, the job strain threshold is set for a demands score higher than 20 and a control score lower than 71; the isostrain threshold is determined from a combining score of job strain and social support lower than 24. We would ask the participants to fulfil the questionnaire from memories that they keep of their work.
Measured: Once at baseline
ERI questionnaire
The Effort-Reward Imbalance Questionnaire (ERI) is a self-administrated test assessing psychological distress and health problems that may occur when there is an imbalance between the efforts required by the work and the rewards received. We used the 46 items of the French version of the ERI model exploring efforts (six items), over commitment (eleven items), and rewards (seventeen items). Items of ERI were scored on a five-point Likert-type scale, ranging from 1 = disagree to 5 = agree and very disturbed. A ratio extrinsic efforts and rewards can assess the imbalance between these two dimensions. A ratio greater than one defines employees exposed to an imbalance between efforts and rewards.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
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).
