Earlier this year, William Lassek, an epidemiologist at the University of Pittsburgh in Pennsylvania, and anthropologist Steven Gaulin of the University of California, Santa Barbara, reported that women who accumulated more fat on their hips than on their waists--and who, therefore, had low waist-hip ratios like many movie stars--had higher cognitive test scores, as did their children.

According to the rudiment epidemiological investigation in our country. The ratio of male to female is 1:3. RA regardless of for traditional Chinese medicine or Western medicine, is still a kind of difficult treat disease. Major is the cause of this disease with pathologyical mechanism lack all-sidely thorough understanding, and lack peculiarness laboratory index in the early stage of disease, so early diagnosis is very difficult.

我国经过初步流行病学调查，RA发病率为0.3～0.5%，男女发病比例约为1：3，西医对本病病因和发病机制认识尚欠清楚，缺乏具有针对性的特效药物；虽然据临床报道中医药对RA具有良好的治疗效果，但由于RA的中医证候分类繁多，目前尚无统一证候分类标准，临床疗效观察缺乏可重复性，严重制约了中医对RA研究的深入开展。
