As a NOPREN collaborating center, the Johns Hopkins Global Obesity Prevention Center and Center for Adolescent Health is conducting mixed-methods formative research to further develop the Baltimore low-income food environment (BLIFE) model. The BLIFE model is an agent-based model (ABM) of Baltimore city adolescents (10-14 years) interacting with their food environment in urban low-income neighborhoods, including geo-specified homes, food outlets, schools, and recreation centers. The expanded model will include a larger part of the city, information on specific schools, additional food sources, adults and their diets.
The Johns Hopkins Global Obesity Prevention Center and Center for Adolescent Health have identified the following aims for this project:
- Conduct formative research to collect additional data on the food behaviors and environment at the household, school, additional food sources, and recreation center levels.
- Iteratively revise our existing ABM with this collected data and then utilize revised models to test the impact of and refine policies/programs for these venues.
- Develop a process and the associated ABM tool that can be used to guide data collection, study development, and implementation of obesity prevention programs and policies.
- Offer our approach and tool to the NOPREN network to guide and refine their studies and translation of results to policy makers.
