Asthma-I: Introduction

3.1K
Asthma is a chronic respiratory ailment that requires careful management due to its varying symptoms and influencing factors. It is characterized by airway inflammation, bronchial hyperresponsiveness, and reversible airflow obstruction, leading to symptoms like wheezing, shortness of breath, chest tightness, and coughing. The symptom frequency and intensity may vary considerably over time. It is also linked to immune system responses to allergens and irritants, highlighting the complex...

Asthma: Pathogenesis and Management

995
Asthma is a chronic pulmonary condition involving inflammation of the airways, hyper-reactivity, and reversible obstruction of the airways. This condition can significantly impact a person's quality of life, making breathing difficult and leading to distressing symptoms.
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.

Area of Science:

  • Epidemiology
  • Pediatric Allergy and Immunology
  • Global Public Health

Background:

  • The Global Asthma Network (GAN) Phase I study builds upon the established International Study of Asthma and Allergies in Childhood (ISAAC) methodology.
  • It aims to survey school pupils across diverse global settings, including high-income and low- to middle-income countries.

Purpose of the Study:

  • To conduct a global survey of asthma and allergy symptoms, risk factors, and management in school-aged children and adolescents.
  • To assess trends in asthma and allergy prevalence by leveraging data from centers that also participated in previous ISAAC studies.

Main Methods:

  • Utilized a cross-sectional survey design with participants from randomly selected schools between 2015 and 2020.
  • Employed validated ISAAC methodology, collecting data through questionnaires administered to adolescents at school and to parents/guardians for both children and adolescents.
  • Collected data on asthma/allergy symptoms, risk factors, management, school/work absence, and hospitalizations.

Main Results:

  • Successfully completed quality checks in 53 centers across 20 countries by May 2020.
  • Achieved high response rates: 88.8% for 132,748 adolescents and 79.1% for 91,802 children.
  • Demonstrated excellent data completion for risk factors (>97%) and asthma management, absence, and hospitalization (>98%).

Conclusions:

  • The Global Asthma Network (GAN) Phase I successfully maintained the high response rates characteristic of the ISAAC study.
  • The data collected will enable crucial within-center analyses of time-trends in asthma and allergy prevalence.
  • GAN Phase I provides a robust foundation for understanding and addressing the global burden of asthma and allergies in children and adolescents.
