title: Sit less, stand more: A randomized point-of-decision prompt intervention to reduce sedentary time.
abstract: OBJECTIVE
  To determine if a point-of-decision prompt (PODP) targeting sedentary behaviour influenced the proportion of standing individuals during presentations at an academic conference.
  
  
  METHODS
  Twelve, one-hour groups of presentation sessions (Global Summit on the Physical Activity of Children conference, May 2014) were included in this study; half were randomly assigned to the intervention group and half to the control group. The intervention group was exposed to an oral PODP at the beginning and middle of the presentations. Researchers performed three counts: beginning (e.g. first 10min), middle (e.g. 30-40min), and end (e.g. 50-60min); each count included the number of individuals in the audience and the number of standing individuals.
  
  
  RESULTS
  A significantly larger proportion of individuals chose to stand during intervention group presentations (16.9±2.0%) compared to control group presentations (10.5±1.5%; chi(2)=7.13; p<0.05).
  
  
  CONCLUSIONS
  This study demonstrated the effectiveness of PODPs at decreasing sedentary behaviour during an academic conference. PODPs are simple, cost-effective interventions that require minimal time commitment, and represent a population health intervention that could reduce sedentary behaviour in a large group setting.
