A Technology-Enhanced Physical Activity Intervention: A Feasibility Study

Area of Science:

• Public Health
• Gerontology
• Exercise Science

Background:

• Physical inactivity and cardiometabolic health disparities are prevalent in ethnic minority populations.
• Midlife adults, particularly first-generation Korean Americans, often face barriers to regular physical activity.
• Technology-enhanced interventions show promise for improving health behaviors in underserved communities.

Purpose of the Study:

• To evaluate the feasibility and acceptability of a technology-enhanced physical activity intervention.
• To assess the intervention's impact on self-efficacy, physical activity levels, and cardiometabolic health.
• To explore the potential applicability of the intervention for diverse ethnic groups.

Main Methods:

• A single-group, pre-posttest design was employed.
• The intervention included education sessions, group walks, and text message reminders over 12 weeks.
• Participants included 43 physically inactive, midlife, first-generation Korean American adults.

Main Results:

• The intervention demonstrated high feasibility with 100% retention, 93% adherence, and 88.4% satisfaction.
• Significant improvements were observed in self-efficacy and moderate physical activity levels.
• Participants showed enhanced cardiometabolic health outcomes post-intervention.

Conclusions:

• The technology-enhanced intervention is feasible, acceptable, and effective for improving physical activity and cardiometabolic health in this population.
• The intervention's ease of use and motivational aspects suggest broad applicability across different ethnic groups.
• Future research should involve larger, multisite randomized controlled trials to confirm findings and address health disparities.
