Peer Motivation Coaches, Social Media-based Support Group, and Behavior Change Strategies to Decrease Prolonged Sitting and Increase Moderate Exercise Snacks

The MOV'D (Move Often eVery Day) intervention is a remotely-delivered, peer-supported intervention that delivers exercise snack (2-5 minutes of moderate to vigorous activity) and behavior change technique (BCT) videos to a private social media support group with the goal of interrupting prolonged sitting at work with MVPA minutes.

The preliminary efficacy, feasibility, and acceptability trial will test the effects of MOV'D, a socially-supported, evidence-based behavior change technique educational and behavioral intervention to increase the number of active hours (an indirect measure of prolonged sitting bouts) (Hypothesis 1) and number of MVPA minutes (Hypothesis 2). This pilot will gather important estimates of the effect sizes, the variance, and covariance of the primary outcomes to calculate the sample size needed to power a larger fully powered RCT.

About this study

Prolonged sitting and inadequate moderate to vigorous intensity physical activity (MVPA) are pervasive risk factors for cardiovascular disease (CVD). Recent research has shown that some benefits of moderate to vigorous physical activity can be accrued in motivationally accessible short, 2-5 minute bouts throughout the day rather than needing to be a single, longer, continuous bout. The MOV'D intervention is a novel, remotely-delivered, social-media-based intervention to interrupt prolonged sitting with short bouts of MVPA, compared with a Fitbit-only control. The investigators will randomly assign participants to either MOV'D or a Fitbit only control for one month, with a one-month follow-up, to compare immediate and prolonged effects of treatment on number of workday hours with activity break and number of MVPA minutes.

Treatment and study plan

MOV'D (Move Often eVery Day)

Behavioral

The MOV'D intervention is a remotely-delivered, peer-supported intervention that delivers exercise snack (2-5 minutes of moderate to vigorous activity) and behavior change technique (BCT) videos to a private social media support group with the goal of interrupting prolonged sitting at work with MVPA minutes.

Fitbit Self-Monitoring

Behavioral

All participants receive a Fitbit and are told to monitor their physical activity for the duration of the study period.

Primary outcomes

  1. Change in average active workday hours at post-intervention

    Time frame: 5 days at baseline, 5 days after 1 month treatment

    Average hours with >2 min of MVPA (Moderate to Vigorous Physical Activity) or 250 steps between 8 AM - 7 PM per workday (of five); proxy for prolonged sitting time

  2. Change in average workday MVPA minutes at post-intervention

    Time frame: 5 days at baseline, 5 days after 1 month treatment

    Average minutes of moderate to vigorous minutes, or minutes above 3 METs per workday (of five) at

Secondary outcomes

  1. Change in average active workday hours at follow-up

    Time frame: 5 days at baseline, 5 days post 1-month follow-up

    Average hours with >2 min of MVPA or 250 steps between 8 AM - 7 PM per workday (of five); proxy for prolonged sitting time

  2. Change in average workday MVPA minutes at follow-up

    Time frame: 5 days at baseline, 5 days post 1-month follow-up

    Average minutes of moderate to vigorous minutes, or minutes above 3 METs +per workday (of five)
