Office Worker Behavior and Health Study

Study Overview
=================
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.

Design Details

Primary Purpose: Prevention
Allocation: Randomized
Intervention Model: Parallel Assignment
Interventional 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.
Masking: None (Open Label)


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Intervention: electronic prompt to interrupt sitting time<br>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. | Behavioral: Electronic Prompt for Interrupting Sitting Time<br>* 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.<br>|
| No Intervention: Control Group<br>The control group will be given an Amazfit BIP device to record their steps. They will submit their daily steps counts for weeks: 1,2,4, 6 and 8. | |

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Sitting Time | Percent of time sitting in a typical workday | Change measure: baseline and 6 weeks | 
| Activity in steps | The number of steps taken during their workday | Change measure: week 2 and 6 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| An Index of Job Satisfaction | This index is by Brayfield and Rothe. There are eighteen questions which assess job satisfaction utilizing a 5-point Likert scale. | Change measure: baseline and 8 weeks | 
| Musculoskeletal complaints questionnaire | 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. | Change measure: baseline and 8 weeks |
