Within group mean changes from baseline in physical activity, diet, and health-related quality of life. Results displayed are estimated mean changes from baseline for primary (steps/day) and secondary outcomes focused on physical activity, diet, and self-rated health. Solid circles (Comparator) and triangles (Intervention) represent estimated group mean change from baseline and bars represent associated 95% confidence intervals. Confidence intervals not including zero (i.e., not crossing the horizontal dotted line) indicate significant differences from baseline. P-values correspond to between-group differences at 6 months. Panel a displays average steps/day measured over a 7-day period using Yamax Digiwalker (SW-200) pedometers; Panel b displays total physical activity in MET-minutes/week (with a square-root transformation applied) and Panel c displays time spent sitting on a week day in minutes/day (with a log transformation applied) both derived from the IPAQ-SF; Panel d displays total healthful eating calculated from the STC questionnaire (lower score = more healthful eating; score range: 0–16); Panel e displays total fatty food derived from a modified version of the Dietary Instrument for Nutrition Education (lower score = less fat consumption; score range: 8–68); Panel f displays self-rated health, which is the VAS score from the EuroQol questionnaire (higher = better state of health; score range: 0–100). Abbreviations: IPAQ-SF = International Physical Activity Questionnaire – Short Form; MET = Metabolic Equivalent; STC = Starting the Conversation; VAS = Visual Analogue Scale
