Office Worker Behavior and Health Study
Condition: Sedentary Behavior
Study type: Interventional

Summary: 
      This is a randomized intervention study to determine if electronic prompted interruptions in
      sitting time have an effect on job satisfaction, musculoskeletal complaints, and sitting
      time.
    

Detailed description: 
      A sedentary lifestyle has been deemed deleterious to health. It contributes to many chronic
      diseases and illnesses as well as an increase in all-cause mortality. The objective of this
      study is to investigate if electronic prompted interruptions in sitting time can reduce
      sedentary behavior at work as well as have an effect on job satisfaction, and musculoskeletal
      complaints. The participants will be randomly assigned to one of two groups, intervention
      (n=31) and control (n=31). Informed consent, demographic and socioeconomic data will be
      obtained from each participant. A questionnaire that includes three different scales will be
      administered before and after the 12-week intervention to all participants: Occupational
      Sitting and Physical Activity Questionnaire, Job Satisfaction Index, and Nordic
      Musculoskeletal Symptoms. Also, physical data will be measured: BMI, percent body fat and
      waist circumference. All participants will be provided with the Amazfit BIP device to track
      steps during work hours. The intervention group will receive a prompt every hour during their
      workday via an iOS application, Stand-Up, through the Amazfit BIP device. The prompt is to
      interrupt sitting time and encourage two-minutes of physical activity. The intervention group
      will receive examples of physical activity in addition to educational material on the health
      benefits of increasing physical activity in the workplace via verbal instruction and written
      materials. Data analysis will be conducted to determine if there is a difference in sitting
      time between the two groups over time using repeated-measures ANOVA. Independent samples
      t-tests will be used to compare job satisfaction and the physical biomarkers for obesity
      among the intervention and control groups. Chi-square will be used to analyze the reported
      musculoskeletal complaints between the two groups. If necessary, all analyses will be
      controlled for age, gender, race/ethnicity, and socioeconomic status.
    

Intervention name(s): Electronic Prompt for Interrupting Sitting Time
Intervention type(s): Behavioral
Intervention description(s): An electronic prompt via the IOS application Stand-Up will be given through the Amazfit BIP device to interrupt sitting time every hour during the office workers workday. The office worker will engage in 2 minutes of physical activity with each prompt.
Allocation: Randomized
Intervention model: Parallel Assignment
Intervention model description: Participants will be randomly assigned to one of two groups: intervention or control after informed consent is obtained. The intervention will be conducted for 8-weeks and consist of two components: education and electronic prompt to interrupt sitting time. Upon receiving the electronic prompt, the intervention group is encouraged to participate in 2 minutes of physical activity. Both groups will be provided an Amazfit BIP device to record and submit their step count during weeks: 1,2,4, 6 and 8.
