A Comparison of Characteristics From the Three CORD Demonstration Sites^23–27

Data/design elements	Commonalities across sites	Differences between sites
Participants
Population characteristics	• High proportion low income, CHIP eligible • High rates of obesity • 2- to 12-year-old children	• Race/ethnic composition • Geographic location
Participants inclusion criteria	• All sites have children ≥85th percentile of BMI as part of the sample	• BMI percentile cutoff for sample inclusion varies
Participant sampling	• Intervention and comparison participants are drawn from populations with similar sociodemographic characteristics	• Recruitment occurs in different settings (community and/or clinic recruitment).
Interventions
Intervention framework	• Multisetting, multilevel interventions: All include interventions in ECE, schools, healthcare, and the community targeting individual and family behavior change as well as PSE changes • Cross-setting linkages (e.g., CHW, coalitions)	• Specific interventions differ by site
Strategies	• Increase fruit and vegetable consumption, water intake, and physical activity and improve sleep • Decrease fatty foods, sugar drink intake, and screen time	• Specific strategies to accomplish overarching strategic goals differ by site
Consortium	• Partners composed of public health department, academic center, and partnerships across settings and sectors	• Sites have various additional partners
CHW	• Integrate across settings • Overarching activities similar	• Primary setting base (e.g., clinic, community) • Specific tasks (e.g., counseling, case management)
Capacity	• All are designed to take evidence-based interventions and build on community capacity. • All allow for additional supports to be leveraged by the CORD intervention	• Capacities differ by community • Additional supports leveraged differ by community (e.g., awards of additional grants)
Comparisons
Catchment areas	• All sites selected a comparison community with similar sociodemographic characteristics, but were not supported with CORD multisetting, multilevel interventions	• Catchment community geographical boundaries vary  ○ Comparison area within the same city as intervention area  ○ Comparison city within the same county as intervention city  ○ Comparison city within the same state as intervention city
Groups	• All sites include groups of full CORD intervention components (public health and primary care plus)	• Sites also include one or two comparison groups of partial intervention components (public health and primary care; public health; primary care plus)
Outcomes
Data type, cohort	• Longitudinal outcome data are gathered on parents and children in primary intervention groups	• A mix of longitudinal, cross-sectional data are collected in comparison groups
Design	• Quasi-experimental	• Some subgroups are matched or randomized
Timing	• Two years of intervention activities • All include clinical data collected at 0 and 12 months	• Intensity differs at different points in the interventions • Sites have additional measurement time points from data derived in clinical and public health settings
Measures	• Common outcome measures for individuals  ○ Assessments   ▪ Weight-related changes: height, weight, BMI   ▪ Sociodemographics  ○ Behaviors   ▪ Fruit and vegetable consumption   ▪ Sugary beverage consumption   ▪ Water consumption   ▪ Physical activity   ▪ Screen time   ▪ Sleep time  ○ Quality of life  ○ Parenting strategies  ○ Satisfaction with healthcare • Common outcome tools for populations  ○ PSE-level measures in all settings	• Site-specific measures assess elements unique to each site and provide additional insights on interventions.
CORD products	• Cross-site evaluations including impact, process, sustainability, cost, and success stories	• Site-specific evaluations, toolkits, and materials
