Marrero, PhD, talks about diabetes, he is not shy about using strong language. “Diabetes may be the most serious public health crisis of our time,” said Marrero, director of the University of Arizona Health Sciences Center for Border Health Disparities in Tucson. “If you think our healthcare system is stressed now and that the costs are exacerbated, put another 40 to 50 million people with diabetes into the mix, and we’ll be in very deep trouble.”
