ACHD was selected to join the CHOICES Learning Collaborative Partnership in 2018. This year-long process brings together health agencies and the expertise of the CHOICES team to build capacity among local decision-makers to use cost-effectiveness analysis to identify childhood obesity prevention strategies that offer the best value for money. This partnership process helps to cultivate alliances and support for future childhood obesity prevention planning.
Modeling
The CHOICES microsimulation model predicts what will happen in the future if we do not implement childhood obesity prevention strategies. We created a virtual population of people who look like real people in Allegheny County. We projected their growth over time, taking into account trends from health and behavior data and population growth. We predict future obesity rates 10 years later, as well as future obesity related health care costs. We compare what happens if we implement these strategies versus what happens if we do nothing.
To create the model, ACHD spoke with real experts for the two strategies of Active PE and Afterschool Snack Policies. Active PE experts included Physical Education (PE) teachers, education researchers, and school administration. Afterschool experts included out of school time program staff and directors. These experts met with the CHOICES Team at two in-person site visits and spoke with ACHD staff about their experiences with PE and food served during out of school time programs. Conversations and data from experts, along with Live Well Allegheny Community Partners helped to build the model.
