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. The current mixed-methods feasibility study explored the impact that a three-month community-based (CBI) and a home-based intervention (HBI) had on improving physical activity and fitness levels, as well as psychosocial outcomes (self-efficacy and social support) among low-income, ethnic-minority mothers. Thirty mothers were randomized to either a three-month community-based intervention (CBI) or a home-based intervention (HBI) and completed pre- and post-intervention assessments of physical activity (self-report, accelerometer), fitness (cardiorespiratory, muscle endurance and strength, flexibility), self-efficacy, and social support. Post-intervention focus groups were also conducted. Through formative research, this pilot work will develop and empirically test a CBI and HBI among low-income mothers for use in local community centers. The results of the proposed work have substantial public health implications and are expected to advance the investigator's understanding of how low-income mothers effectively use these intervention modalities to adopt healthy behaviors and produce change that can positively impact their health, as well as that of their children. Further, the proposed research will yield two physical activity interventions that can be readily delivered in community settings, are scalable, and are relatively low cost. Finally, these results will help identify those subgroups of mothers that may do particularly well (or poorly) with these innovative approaches to physical activity adoption and maintenance. This has important implications for the tailoring of physical activity programs to individual needs and preferences.
