In response to the rise in obesity rates and obesity-related healthcare costs over the past several decades, numerous organizations have implemented obesity prevention programs. The current method for evaluating the success of these programs relies largely on annual surveys such as the Centers for Disease Control and Prevention’s Behavioral Risk Factor Surveillance System (BRFSS) which provides state-by-state obesity rates. As a result, public health policy makers lack the fine-grained evaluation data needed to make timely decisions about the success of their obesity prevention programs and to allocate resources more efficiently.
Objective
We developed Persistent Health Assessment Tools, PHAT, to equip public health policy makers with more precise tools and timely information for measuring the success of obesity prevention programs. PHAT monitors social media to supplement traditional surveillance by making real-time estimates based on observations of obesity-relevant behaviors.
