Darth, this must be the study you're talking about.
China faces a diabetes epidemic, with almost one in 10 adults having the disease while most cases remain undiagnosed, researchers have said.</blockquote>
I had friends from China in college and not a single one of them was overweight. Infact, all of them were very slim. But they would tell me the trend was changing back home. Especially in the cities where folks had access to fast food chains like McDonald's, it was common to find overweight and obese kids. When they were growing up, they had madatory Phys Ed classes and just like Math and Science, they had to pass Phys Ed exams to be promoted to the next class.
It's sad to see the same trend happen in other developing nations too. India has one of the highest diabetic population in the world.
