Hierarchical analysis of Mediterranean Dietary pattern on atopic diseases' prevalence in adolescence: The Greek Global Asthma Network study.

Introduction: The contribution of dietary patterns in the occurrence of atopic diseases, mainly asthma, allergic rhinits, and eczema is ambiguous. Our study examined the association between the level of adherence to the Mediterranean diet (MedDiet) and the prevalence of atopic diseases in adolescence.

Methods: A total of 1934 adolescents (boys: 47.

Parental education moderates the association between indoor moisture environment and asthma in adolescents: the Greek Global Asthma Network (GAN) cross-sectional study.

Objective: Asthma is a major contributor to childhood morbidity. Several environmental and socioeconomic status (SES) factors have been implicated in its etiopathogeneses such as indoor moisture and parental education level. Our study examined the association between exposure to indoor dampness and/or mould (IDM) with adolescent asthma and how parental education could modify or mediate this relationship.

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.

Background: The Global Asthma Network (GAN) builds on the International Study of Asthma and Allergies in Childhood (ISAAC).

Objective: To compare asthma prevalence time trends in primary and secondary school children in four Mexican centers participating in ISAAC and GAN.

Methods: GAN is a cross-sectional, multicenter, epidemiological methodology carried out in groups of primary school children aged 6-7 and adolescents aged 13-14 following the ISAAC Phase Three protocol, with additional questions on risk factors and asthma management.

Global Asthma Network Phase I Surveillance: Geographical Coverage and Response Rates.

Background-The Global Asthma Network (GAN) Phase I is surveying school pupils in high-income and low- or middle-income countries using the International Study of Asthma and Allergies in Childhood (ISAAC) methodology. Methods-Cross-sectional surveys of participants in two age groups in randomly selected schools within each centre (2015-2020). The compulsory age group is 13-14 years (adolescents), optionally including parents or guardians.
