Active Moms: a feasibility study of a community-based and home-based physical activity intervention for low-income, ethnic-minority mothers

BACKGROUND: Despite the health benefits of physical activity, increasing regular physical activity levels among low-income, ethnic-minority mothers has remained a significant challenge. Yet, few studies have examined the feasibility of implementing interventions to address physical activity barriers often experienced by this population. METHODS: The current mixed-methods pilot study assessed the feasibility, impact, and acceptability of a 3-month community-based (CBI) and a home-based intervention (HBI) designed to improve physical activity and fitness levels, as well as psychosocial outcomes (self-efficacy and social support), among low-income, ethnic minority mothers. Mothers were randomized to either a 3-month CBI or HBI and completed pre- and post-intervention assessments of physical activity, fitness, self-efficacy, and social support. Intervention feasibility was assessed by tracking recruitment, retention, and adverse event rates, whereas intervention acceptability was assessed through post-intervention focus groups. RESULTS: Although participant recruitment was lower than expected (30 vs. target of 52 mothers), retention and adverse event feasibility goals were met (> 60% retention rate, 0% adverse events). Mothers in both groups (CBI and HBI) showed significant improvements in their physical activity and fitness levels and short-term improvements in receiving social support for physical activity. However, only mothers in the CBI group showed improvements in their self-efficacy for physical activity. Mothers also reported both types of interventions (CBI and HBI) to be acceptable with minor modifications highlighted, including the potential for graduates of these programs to serve as group facilitators. CONCLUSIONS: Overall, the study protocol was feasible, impactful, and acceptable to low-income, ethnic minority mothers with modifications required before large-scale evaluation.
