The obesity rate has been rising rapidly in America over the past two decades. Many factors have been identified as contributors to this ongoing public health crisis. The food industry plays a powerful role shaping public perceptions of food and eating behaviors, as this Vox article explains.
As a geographer, I am always concerned with the influence of our surrounding environment on what we perceive and how we behave. In this paper, my coauthors and I have considered the impacts of built and natural environments on physical inactivity and correspondingly obesity rate. We have made a couple of findings. First, higher street connectivity and walk scores are related to lower physical inactivity and obesity rates. In a more pedestrian-friendly environment with more streets and connections, people tend to be more physically active and less likely to be obese. Second, higher ratio of fast-food restaurants in a community is positively related to physical inactivity and obesity. Surprise, surprise, fast-food makes people become more obese, well, because in the fast-paced modernity, fast-food is literally fast and therefore convenient for people to grab and eat on the go.
Last but not least, the number of extreme weather events is also found to lead to physical inactivity and obesity. When extreme weather events occur, the environment outside the window all of a sudden becomes hostile. People are constrained inside, much less likely to get engaged in any exercises. So, these extreme weather events pose threats to not only public safety but also public health.
