- Behavioral: Electronic Prompt for Interrupting Sitting Time
- Registration Number
- NCT04042610
- Lead Sponsor
- Loma Linda University
- Brief 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.

Group Intervention Description Intervention: electronic prompt to interrupt sitting time Electronic Prompt for Interrupting Sitting Time The intervention will consist of two components: education and an electronic prompt via the iOS application Stand Up and notification through the Amzafit BIP device. The Stand-Up application will generate a prompt every hour during the workday to interrupt sitting time and encourage 2 minutes of physical activity. The intervention group participants will be given verbal and written educational materials on the health benefits of incorporating physical activity throughout their workday as well as the health risks of a sedentary lifestyle. Suggestions and demonstrations of physical activity will be given including but not limited to: use a restroom further away from their workstation, take a brief walk around the office, walk-in place, stretch. In addition, they will record their steps via the Amazfit BIP device and submit their daily step counts for weeks: 1,2,4, 6 and 8.
- Primary Outcome Measures
Name Time Method Activity in steps Change measure: week 2 and 6 weeks The number of steps taken during their workday
Sitting Time Change measure: baseline and 6 weeks Percent of time sitting in a typical workday
- Secondary Outcome Measures
Name Time Method Musculoskeletal complaints questionnaire Change measure: baseline and 8 weeks The questionnaire is also known as the Nordic Musculoskeletal Questionnaire. It uses Yes or No response to assess whether or not the participant has had musculoskeletal trouble in their neck, shoulders, upper back, elbows, wrists/hands, lower back, hips/thighs, knees, or ankles/feet over the past twelve months, if musculoskeletal problems have prevented normal function or working during the past twelve months, or if there has been musculoskeletal trouble during the past seven days.
An Index of Job Satisfaction Change measure: baseline and 8 weeks This index is by Brayfield and Rothe. There are eighteen questions which assess job satisfaction utilizing a 5-point Likert scale.
