I would say that Diabetes was the epidemic of the 20th century, and obesity is the epidemic of the 21st. During the 20th century, diabetes rose in incidence, and we treated it as a disease. In the 21st century, we understand that diabetes is caused by obesity. And now we're just beginning to find new and better ways to treat obesity.
No. Epidemics occur when enormous wave(s) of a highly contagious disease sweeps through an area. For example, if most to all of the city of New York came down with the flu, then that would be a flu epidemic in New York City. Obesity and diabetes are not contagious diseases; they are medical conditions, and are not spread by bacteria or viruses. Though many people in the U.S. suffer from diabetes or obesity, they did not catch it from someone else. Can you catch excess weight? Can you visit a diabetic friend and come down with high blood sugar? In the case of the former, it is usually caused by either metabolism/thyroid problems and/or lifestyle, and is not transmitted from one person to the other. In the case of the second, diabetes is caused by a variety of factors, but again, is cannot spread. See related links.
With the rising instance of diabetes worldwide, it could be construed as such.
