China ? After working overtime to catch up to life in the West, China now faces a whole new problem: the world’s biggest diabetes epidemic.

One in 10 Chinese adults already have the disease and another 16 percent are on the verge of developing it, according to a new study. The finding nearly equals the U.S. rate of 11 percent and surpasses other Western nations, including Germany and Canada.

The survey results, published today in the New England Journal of Medicine, found much higher rates of diabetes than previous studies, largely from more rigorous testing measures. With 92 million diabetics, China is now home to the most cases worldwide, overtaking India.
