Effect of intervention on activity and diet
Self-efficacy for healthy eating and physical activity levels was high across all study arms at baseline (mean 4.27; 95%CI 4.16, 4.39 for healthy eating and mean 3.76; 95%CI 3.62, 3.89 for activity). There was no difference in self-efficacy for healthy eating and physical activity levels at enrollment and follow up by study arm and no difference in the change in self-efficacy towards healthy eating and activity across the study. Participants in all three arms had a decrease in physical inactivity time and increase in physical activity across the study period with no difference by arm. Mean score on the Block Sodium Screener increased during the study period in the control and HBPM alone arm by 2.2±13.0, but decreased in the HH4NM + HBPM arm; -3.9 ± 12.2, p=0.02 in post-hoc analysis of HH4NM + HBPM vs. other arms (HBPM alone and control).
