The document discusses the evolution of the obesity epidemic in the United States and Massachusetts. It describes how obesity rates more than doubled among adults and more than tripled among children nationally between the 1980s and 2000s. This led to increased risk of chronic diseases. While Massachusetts had lower rates than the national average, its rates were also steadily increasing. The document outlines how certain populations in Massachusetts, such as Black and Hispanic residents, faced significantly higher obesity rates and related health disparities. This represented both a public health and economic crisis for the state.
