A remote booster program to attenuate sedentary behaviour in patients with coronary artery disease: (SIT LESS) Booster

This data sharing collection contains materials used and data collected as part of the (SIT LESS) Booster study.

Aims: Sedentary time (ST) can be reduced in patients with coronary artery disease (CAD) during cardiac rehabilitation (CR), but most patients relapse to sedentarism within months. We examined the effectiveness of a 3-week remote booster intervention on ST changes in CAD patients.

Methods: CAD patients who previously (2.0 [1.9 – 2.2] years) completed CR were included in this randomized controlled trial (1:1, stratified for gender). All participants received usual care, whereas booster participants additionally received a 3-week remote behavioral change intervention. The primary outcome was the change in accelerometer-derived ST from baseline to post-intervention and secondary outcomes included changes in sedentary behaviour and physical activity (PA) characteristics. A baseline constrained linear mixed-model on an intention-to-treat basis was used.
