Coordinating community social ecological system dynamics through data-driven population health improvement science for  physical activity, nutrition, and other cancer prevention behaviors in children.

Healthy Youth Places School Model for Data-Driven Community Population Health Improvement

Picture
Our research team has developed an approach to community population health improvement based on creating an architecture for multi-level system coordination through facilitating local data-driven decision making in the design and implementation of policies, programs, and practices.  

​This approach was first presented as the Healthy Youth Places Framework to create a middle school prevention system with support from the National Institutes of Health RO1 HD37367.

Recent work is presenting the Wellness Landscape Model (Wellscapes) to create a whole-of-community prevention system with support from the National Cancer Institute of the NIH R01CA215420. ClinicalTrials.gov Identifier: NCT03380143

Modeling the Social Interpersonal Practice Dynamics of Children's Organized Group Activities

Our research team has developed an approach to modeling children's organized group activities impact on high frequency preventive health behaviors, such as physical activity,  through modeling the system interpersonal coordination pattern dynamics defined by space and time boundaries.

​​"We started rigorous community research in 1999 as part of a National Institutes of Health school randomized trial of how to build healthy youth places.  We formed www.healthyplaces.org as a place-based approach to improve the health (physical activity and nutrition) and development of youth.  Now we are leading innovation on whole-of-community systems research with new strategy, fostering locally lead efforts to build equitable community opportunities or wellness landscapes (www.wellscapes.org) for youth. This work is funded by the NIH National Cancer Institute."

"Our laboratory is investigating community, organization and group processes that drive structural opportunities for improved youth health behavior.  We study community-driven practices through rigorous research methods using video observation and objective measurement of health behavior, such as using accelerometers to measure physical activity.  By pairing measures of community, organization, and group structures and processes with measures of health behavior, we can establish how community social ecological systems impact the lives of youth, how structures in opportunities impact youth,  and what communities can do to provide more opportunities for all children."
"Wellscapes is a method for community-driven efforts to build a community landscape of healthy places. A community with a patchwork of different places providing healthy opportunities where children and families go, such as school, after school programs, clubs, faith groups, and youth sport, can provide a local environment to support healthy development and behavior. By using data to drive decision making, embedding community systems change, and providing professional development, communities can combine efforts to create a mosaic of healthy places to live, work, learn, and play.  Click on wellscapes.org to signup for the community population health improvement method for children"
