| Popis: | Introduction: Lifestyle interventions incorporating exercise and nutrition can help prevent and manage cardiometabolic disease. However, not all interventions readily reach individuals who are most in need. A mobile health (mHealth) exercise program could be a cost-effective approach to broadening accessibility and providing support for physical activity behavior change. We tested the feasibility and acceptability of a mHealth exercise intervention in this 8-week pilot study. Hypothesis: A remotely delivered mHealth lifestyle program involving a wearable sensor, mobile application and social support is feasible and acceptable in sedentary adults. Methods: A total of 84 sedentary (< 30 min/week of exercise) adults (females 31.5 ± 11.3 yr, males 34.1 ± 28.9 yr, mean ± SD) were randomized (1:1:1) to 8 weeks of increasing physical activity behavioral support: Level 1 (wellness education, n=26), Level 2 (wellness education + pre-recorded exercise videos, n=30), or Level 3 (wellness education + livestream group exercise, n=28). Participants used a chest strap sensor (Myzone MZ-3) during exercise and a mobile application for interaction. A weekly email was used to deliver wellness education and encourage physical activity. Level 2 exercise videos and Level 3 livestream (Zoom) group classes were 35 min long, instructor-led, delivered 3x/wk and designed to meet national guidelines for weekly physical activity. Participants were surveyed at baseline and 8 weeks. Feasibility was defined through accrual and attrition; acceptability through sensor use (3x/wk encouraged) and survey data. Results: Between August 2020 and August 2021, 204 adults were screened for eligibility. Out of 135 eligible participants, 84 (62%) enrolled in the study. Preliminary analysis indicated 65% retention at 8-week follow-up. Participants were primarily Hispanic/Latinx (47%), 71% had 2-year college or more education, 45% reported income below federal poverty thresholds, and 36% reported qualifying for public assistance. Program acceptability varied by group with weekly median sensor use of 1 day/wk (Level 1), 2 days/wk (Level 2) and 3 days/wk (Level 3). Good-to-high program enjoyment was reported by 90% of Level 3 and 83% of Level 2 participants. Conclusions: This pilot study demonstrates that a livestream group-based or video-based exercise program is feasible and acceptable in sedentary adults. A randomized controlled trial investigating health-related outcomes using this mHealth program is warranted. |
