What do the Chinese know about RLS

It would seem that the Chinese have far less percentage of individuals suffering from Restless Leg Syndrome.

A study of nearly 3,000 inhabitants of rural area outside Shanghai showed that only 1.4% of the population suffered from Restless Leg Syndrome. This is significantly less than the prevalence of RLS in the UK where studies have shown that it is regionally 10%. The question is whether such a low rate of RLS due to diet, lifestyle, or perhaps even the Chinese deal with their remedies with herbs and acupuncture. If anybody can shed further light please post a response to this blog.
