Step by Step: A Family-Centered Healthy Lifestyle Intervention

The objectives of this project were to design an evidence-based, family-centered fitness and nutrition program and evaluate the feasibility and acceptability of implementing this program in a Volunteer in Medicine Clinic, discussing successes, challenges and lessons learned.

This prospective pilot study was conducted within a Volunteers in Medicine (VIM) model clinic in Southeastern Pennsylvania from July - December 2012. The VIM Model focuses on providing primary care to children, adolescents and adults that are uninsured. This model is guided by the principles of inclusion, service and community involvement, with volunteers providing the vast majority of health care and support services.

Community Volunteers in Medicine (CVIM) provides primary care and dental care to uninsured adults and children who live or work in Chester County with incomes less than 300% of the federal poverty level. In 2016, Chester County's residents were 7% Hispanic, 24% obese, 9% uninsured and 10% of children living in families with incomes below the poverty level. Most pediatric patients served by CVIM are of Hispanic/Latino descent and have a high prevalence of overweight and obesity (54%), which is higher than the county prevalence of 25% in school-aged children.

After a quality improvement project identified the high prevalence of childhood obesity in children served by CVIM, the authors proposed developing a family-centered obesity treatment program. CVIM's Executive Board committed support to the program. Temple University School of Medicine's Institutional Review Board approved the project. Consent materials were available in English and Spanish.

The program name Step by Step (Paso a Paso) was chosen by consensus, logo designed by a local graphic artist, and T-shirts provided to staff, volunteers and participants. Behavior change theory and goal-setting principles informed the program design. A literature review identified evidence-based best practices. Thirteen 1.5 hour weekday educational sessions, five 1-hour weekday fitness classes and seventeen 1 hour weekend activities were scheduled over 22 weeks. The planned total contact time was 41.5 hours, above the minimum effective amount recommended by the USPSTF. Children participated in all activities. Weekly text messages with motivational messages and reminders were planned. A Manual of Operations detailed the volunteer orientation, session outlines, and handouts. Sessions had bilingual staff and handouts were available in English and in Spanish. Clinic staff, volunteers and family members were encouraged to participate in fitness and nutrition activities.
