1The First Affiliated Hospital, Medical School of Shantou University, Shantou, Guangdong 515041, China.
Objective:

Methods:

Result:
The prevalence of primary gout in Chenghai surveys was 0.17%, 0.15% and 0.26% respectively; no case of primary gout was found in Beijing survey. Among the patients, male to female ratio was 21:1; average onset age of females was significantly higher than that of males. The numbers of patient in the recent 10 years was increasing.
