Promoting Physical Activity and Fitness Among Underserved Latino Families Living in U.S.-Mexico Border Regions

Child Physical Activity (PA)

Total PA (mean minutes/day) in children will be measured objectively with a wrist-worn ActiGraph GT9X Link (Pensacola, United States). According to recommended procedures\[84\], children will be asked to wear the accelerometer continuously on their non-preferred wrist for seven days. Parents will be provided with a sleep diary where they will record their child's wake/sleep times and periods of non-wear. Child and adult CVF performance will be measured via the 1-mile run/walk time in seconds at a local park (usually adjacent to the Community Centers). Study staff will utilize stop watches to collect total mile run time in seconds and record the time in each participant's record log. In addition, a measurement staff will run/walk along with each child participant and provide them with verbal encouragement to put forth their best effort.

Implementation

Will be assessed at multiple levels: participant/families, research team (including Promotores), and Community Center staff. At the participant level, parent-child focus groups will be held and anonymous surveys to assess program satisfaction will be administered. At the staff level; staff and students will be evaluated every 3 months for fidelity by the intervention coordinator through checklists and weekly logs, as well as surveys assessing the feasibility of the program. At the community center level; they will complete brief online surveys involving policy implications, program feasibility, intervention adoption and costs, and reach of recruitment and outreach efforts. Additionally, phone interviews will be held by study personnel to assess appropriateness and sustainability of the AFL intervention.
