Prevalence and risk factors associated with allergic rhinitis in Mexican school children: Global Asthma Network Phase I.

Background: The International Study of Asthma and Allergies in Childhood (ISAAC) showed a wide variability in prevalence and severity of allergic rhinitis (AR) and rhinoconjunctivitis (ARC), in addition to other atopic diseases (Asher et al, 2006). The Global Asthma Network (GAN) has continued to study these conditions.

Objective: To estimate the prevalence of AR and ARC in children and adolescents in Mexico and to assess their association with different risk factors.

Have asthma symptoms in Mexico changed in the past 15 years? Time trends from the International Study of Asthma and Allergies in Childhood to the Global Asthma Network.

International Study of Asthma and Allergy in Childhood Phase III (ISAAC III): The Role of Non-Response in Valencia.

A study was done about non-participation during Phase III of the International Study of Asthma and Allergy in Childhood (ISAAC III) in Valencia to determine whether the non-response rate significantly affected the results obtained in Valencia. Of the schools selected to participate in ISAAC III, 13.3% denied not to, the main reason being they were already participated in a similar study.

Climate and prevalence of atopic eczema in 6- to 7-year-old school children in Spain. ISAAC phase III.
