Changes in risk factors for food sensitization in early life: Analysis over a period of 10 years.

Background: Although epidemiological trends of childhood food sensitization (FS) in IgE-mediated food allergy were reported in China, few studies have examined at changes in its risk factors.

Objective: To investigate the change in early-life risk factors associated with childhood food sensitization during 2009-2019 in China.

Methods: Data from two cross-sectional surveys conducted in 2009 and 2019 (401 and 513 children, respectively) were analyzed.

Trends in the contributions of atopic family history to pediatric food sensitization and allergy.

Objective: Family history of atopic diseases (FHA) contributes to food allergy (FA). But little is known whether FHA primarily increases IgE-mediated, non-IgE-mediated FA, or both. And the trends in the contributions of FHA to food sensitization (FS) and FA remain unclear.

Comparison of the Differences Between Web-Based and Traditional Questionnaire Surveys in Pediatrics: Comparative Survey Study.

Background: A web-based survey is a novel method for data capture. Some studies have applied web-based surveys in pediatrics, but few of them have reported data on the differences between web-based and traditional questionnaire surveys.

Objective: The objective of our study was to evaluate the internal consistency of a web-based survey and compare it with a traditional questionnaire survey in pediatrics.

Time trends of childhood food allergy in China: Three cross-sectional surveys in 1999, 2009, and 2019.

Background: Many countries have recorded the trends of food allergy (FA) prevalence. Little is known about epidemiologic trends of childhood FA in China.

Methods: In three cross-sectional surveys conducted in 1999, 2009, and 2019, the prevalence of and characteristic changes in FA in children aged ≤ 2 years were assessed and the outcomes were compared.
