This project will identify commonly used obesity prevention programs that have limited effectiveness for obesity prevention and are thus a suboptimal use of limited public health resources. The specific aims are to: 1) Identify two commonly implemented childhood obesity prevention interventions targeting children ages 0-8 that may lack evidence for impact; 2) Conduct a systematic evidence review, using CHOICES methodology, to identify a) quantitative estimates, if they exist, for impact of each intervention on children’s obesity risk; and b) implementation costs; and 3) Estimate the population impact, costs to society, healthcare cost savings, reach, and impact on racial/ethnic disparities (if possible) of the two interventions from 2020-2030 using the CHOICES methodology, and compare to previously modeled interventions.
