Based on the results of SPT and medical history, the subjects under went the suspected food elimination and oral food challenge under medical supervision.

Of 1687 children approached, 1604 （550 of Chongqing, 573 of Zhuhai and 481 of Hangzhou） fulfilled the study criteria for diagnosing food allergy. One hundred children were confirmed to have challenge-proven food allergy in 3 cities （40 of Chongqing, 33 of Zhuhai and 27 of Hangzhou）. The prevalence of food allergy in 0-2 years old children in Chongqing was 7.3% , in Zhuhai was 5.8% and in Hangzhou was 5.5%. There was no significant difference in the prevalence of food allergy in children under 2 years among the three cities, and the average prevalence for food allergy in children under 2 years was 6. 2%. Egg（3.0%-4.4% ）was the most common allergen, followed by cow＇s milk （0. 83%- 3.5% ）, shrimp（0. 17% -0. 42% ）and fish（0. 17% -0. 21% ）. Conclusion The prevalence of food allergy in 0-2 years old children in China was 5.5% -7.3%.
