A Scale-Out Study of an Evidence-Based Family Meals Program Delivered in the Head Start Setting: Results, Challenges, and Opportunities.

Background: There is need to identify evidence-based early childhood obesity prevention programs that are feasible and demonstrate cost-effectiveness for a broader health impact. This scale-out study leveraged community-engaged principles to compare the feasibility and cost-effectiveness of three delivery modes of a childhood obesity prevention family meals program (Simple Suppers) that demonstrated positive impacts on child and caregiver diet/nutritional health-related outcomes in a previous experimental trial tested among elementary-aged children. Methods: This three-arm (in-person, online, hybrid) pre-(T0) and post-(T1)-test study included families recruited from Head Start. Forty-five families (45 caregivers; 55 children) completed the study. The program was adapted to families with younger children (3-5 years). During the 8-week program, participants received weekly group education and meals through in-person, online, or hybrid format. Feasibility outcomes were attendance, acceptability (post-test survey; focus groups), fidelity, and cost (food; staff). Participant outcomes were related to diet/nutritional health. Kruskal-Wallis test was used to compare T0 to T1 differences in participant outcomes across delivery modes. Qualitative data were analyzed using thematic analysis. Cost-effectiveness was calculated as the net-cost of the program by changes in outcomes. Results: Overall attendance was 51.2%, and higher for in-person (72.0%) and hybrid (59.7%). Program satisfaction rate was highest for hybrid (93.0%), as well as program fidelity (96.7%). Focus group results revealed areas of program improvement, behavior change, and program approval. Cost was lowest for hybrid ($17.09/family). Children in the hybrid group had a reduced waist circumference (p = 0.02) versus in-person and online groups. Conclusion: The hybrid mode of Simple Suppers demonstrated the greatest scaling potential for a broader public health impact.
