Long-term physical activity outcomes in the Seamos Activas II trial

Latinas report disproportionately low physical activity (PA) levels and related health conditions. Reducing chronic disease in Latinas requires interventions to increase and maintain health-enhancing PA levels; yet limited intervention studies have examined PA maintenance among Latinas. The present...

Reducing chronic disease in Latinas requires interventions to increase and maintain health-enhancing PA levels; yet limited intervention studies have examined PA maintenance among Latinas. The present study evaluated the efficacy during the maintenance phase (months 6–12) of the Enhanced PA intervention for Latina adults in Seamos Activas II compared to the Original PA Intervention. Seamos Activas II was conducted in San Diego, California from 2015 to 2020. Underactive adult Latina women (N = 199), mainly of Mexican descent (89%) were randomized to the original intervention or a theory- and technology-enhanced intervention. Their PA was measured objectively (via accelerometers) and via self-report at baseline, 6, and 12 months. Quantile regression models assessed treatment effects on min/week of moderate to vigorous PA (MVPA) at 12 months. Generalized linear models examined treatment effects on indicators of meeting 2008 National PA Guidelines. Both groups maintained the significant gains in MVPA they had made during the first 6 months of the intervention, neither increasing nor decreasing their MVPA over the maintenance period, with no significant between-group differences. At 12 months, 46.3% of Enhanced Intervention participants were meeting self-reported PA guidelines (vs 35.6 % of the Original PA Intervention arm, p = .02). Even with minimal contact throughout the maintenance phase, participants maintained their MVPA, which underscores the importance of continued use of evidence-based behavior change tools and techniques to reinforce newly established habits.
