A Technology-Enhanced Physical Activity Intervention: A Feasibility Study

Using a single-group, pre-posttest design, we evaluated feasibility and acceptability of a technology-enhanced physical activity intervention in 43 midlife (aged 35-64) first-generation Korean American adults who were physically inactive. The intervention consisted of bi-weekly education sessions for 4 weeks, monthly small group walks for the following 8 weeks, and weekly reminder text messages during the entire intervention period. A 100% retention rate, 93% adherence, and 88.4% satisfaction supported the feasibility and acceptability of the intervention. Paired t-tests revealed the intervention was successful and effective as demonstrating a significant increase in self-efficacy and moderate physical activity and improved cardiometabolic health. This easy and motivation enhancing intervention has a wide potential applicability for other ethnic groups. Further intervention research is suggested in a large sample, multisite, for a longer-term with a randomized controlled trial design, which may lead us to narrow the gap in physical activity engagement and cardiometabolic health disparities.
