简要总结
In today's modern workplace, desk-based work is prevalent, leading to prolonged periods of sitting and limited physical activity among workers. This sedentary behavior can have detrimental effects on the physical and mental health of employees. Besides, this behavior contributes to the rising incidence of metabolic and general health problems in workers, even independently of their physical activity levels, leading to reduced productivity for the company and an increased economic burden on public health.
The Up Project is a Quasi-experimental controlled trial designed to assess the efficacy of two interventions to reduce sedentary behavior in the workplace. The study involves three groups: a) a control group, b) a group with booster breaks (led by professionals), and c) a group with unled computer prompts. The primary outcomes being measured are cardiometabolic risk and stress perception, while secondary outcomes include physical activity, sedentary behavior, and occupational pain.
This study is expected to contribute to the research gap in this area by providing valuable insights into the efficacy of interventions aimed at reducing sedentary behavior and its impact on health in the workplace.
详细描述
The design of The Up Project will be a Quasi-experimental controlled trial controlled trial in which participants will undergo two interventions aimed at reducing sedentary behavior in the workplace. The sample size was calculated using G*Power software and will consist of 60 workers from three higher education centers located in the Valparaiso region of Chile. Participants will be divided into three groups: a) a control group, b) a group with booster breaks led by professionals, and c) a group with computer prompts that are unled.
The study will be conducted in three stages, comprising two visits to our laboratory and one visit to the participants' offices. The first stage will involve a pre-intervention measurement session at our laboratory, which will comprehensively assess various cardiometabolic risk factors, such as body composition (DXA), waist circumference, weight, height, resting heart rate, and blood pressure. Questionnaires will also be administered to assess stress perception (PSS-14), occupational pain (using the Nordic-standardized questionnaire), physical activity (GPAQ), sedentary time at work (OSPAQ), 24-hour behavior (DABQ), eating habits (using the Mediterranean diet adherence questionnaire), smoking habits (using the Fargerstörm test), and socio-economic status (using the distribution and average autonomous income of households by income decile). Furthermore, participants will wear two types of accelerometers, ActiGraph and ActivPAL, for seven days to objectively measure physical activity intensity, sedentary time, and sedentary time breaks.
In the second stage, our research team will visit the participants' offices to remove the devices and administer the questionnaire application for sedentary time at work and 24-hour behavior for a second time. The intervention will commence after the accelerometers have been removed.
Finally, the third stage will involve a second visit to our laboratory, where cardiometabolic risk will be re-evaluated, and questionnaires on stress perception, occupational pain, physical activity, sedentary time at work, and 24-hour behavior will be administered again.
It is worth highlighting that mid-intervention, all three groups will be provided with accelerometers to re-evaluate the subjects' daily physical activity intensity, sedentary time, and breaks in sedentary time.

结局指标
主要结局
Cardiometabolic Risk
时间窗: up to six months
Measurements related to cardiometabolic risk will be obtained through various methods, including DXA scans (General Electrics, model Lunar, series 212069) to determine body composition such as fat mass, fat-free mass, and bone mass. Weight will be measured in kilograms using a digital balance (OMRON HN-289-LA), height will be taken in centimeters with a portable stadiometer (SECA, model 213, GmbH). Additionally, weight and height will be combined to report BMI in kg/m\^2. Waist circumference will be measured in centimeters using a Lufkin metallic tape measure (W606PM), while blood pressure will be measured in millimeters of mercury (mm Hg) using a digital monitor (model HEM-7120, OMRON) and heart rate will be measured in beats per minute using a pulse oximeter model Prince-100B5 (Heal Force).
Stress Perception
时间窗: up to six months
To measure stress perception, we will use the Perceived Stress Scale Questionnaire (PSS-14), which was validated by Cohen, Kamarck, and Mermelstein in 1983 and adapted for Chile by Erik Marín (Marín et al., 2004). The questionnaire assesses the individual's perception of various situations that may be influenced by their level of stress. The PSS-14 questions refer to the last month and are rated on a Likert scale ranging from 0 (never) to 4 (very often) in which a higher score indicates a higher level of perceived stress.
次要结局
- Occupational pain(up to six months)
- Physical Activity and Sedentary Time(up to six months)
