Insights

This study estimated the national prevalence of asthma symptoms in Iranian children. The overall prevalence was 13.14%, highlighting a significant public health concern for asthma prevention and control in Iran.

Area of Science:

  • Pediatric Allergy and Immunology
  • Public Health Epidemiology
  • Respiratory Medicine

Background:

  • Asthma is the most common chronic childhood illness globally.
  • Accurate national prevalence data is crucial for effective public health strategies in Iran.
  • Previous international reports may not fully capture the specific burden of childhood asthma in Iran.

Purpose of the Study:

  • To systematically review and meta-analyze existing data to determine the national prevalence of asthma symptoms in Iranian children.
  • To provide an updated and comprehensive estimate of childhood asthma prevalence across Iran.
  • To inform public health policy and resource allocation for asthma management.

Main Methods:

  • A systematic review and meta-analysis of population-based prevalence studies on childhood asthma in Iran.
  • Searched internet and hand-searched 142 articles, dissertations, and reports published between 1998 and 2003.
  • Selected 19 studies conducted using the International Study of Asthma and Allergies in Childhood (ISAAC) protocol, analyzing data from 61,067 children.

Main Results:

  • Prevalence of asthma symptoms varied significantly across regions, with Kerman reporting 2.7% and Tehran 35.4%.
  • The overall national prevalence of asthma symptoms in Iranian children was estimated at 13.14% (95% CI: 9.97-16.30%).
  • The calculated national prevalence is higher than previously estimated in international reports.

Conclusions:

  • Childhood asthma symptoms represent a substantial public health issue in Iran.
  • The findings underscore the need for targeted asthma prevention and control programs tailored to the Iranian population.
  • This study provides essential data for prioritizing and enhancing asthma care within Iran's public health framework.

Asthma-III: Symptoms and Complications01:24

Asthma-III: Symptoms and Complications

Asthma, a common chronic respiratory condition, is classified considering the frequency and severity of symptoms alongside lung function impairment. Understanding this classification is essential for appropriate treatment and management. Here's a detailed look at the classification of asthma and its clinical features and complications:
Classification of Asthma
Asthma III: Clinical Manifestations01:13

Asthma III: Clinical Manifestations

Asthma presents with a characteristic pattern of episodic respiratory symptoms that reflect underlying airway inflammation, bronchoconstriction, and mucus hypersecretion. Although severity varies among individuals, certain clinical manifestations are considered hallmarks of the disorder and often guide diagnosis and assessment.Respiratory SymptomsA persistent cough is one of the most common early features of asthma. It is frequently dry and tends to worsen at night or in the early morning,...

Asthma-IV: Diagnostic and Management

The diagnosis and management of asthma are comprehensive, encompassing clinical assessments, lung function tests, and pharmacological interventions. Here's an overview:

This is the first step in diagnosing and managing asthma. It includes:
Asthma I: Introduction01:28

Asthma I: Introduction

Asthma is a chronic inflammatory disorder of the airways characterized by variable airflow obstruction and heightened bronchial responsiveness to a wide range of triggers. The underlying inflammation leads to airway swelling, mucus hypersecretion, and smooth muscle constriction, all of which narrow the airway lumen and impede airflow. Clinically, asthma presents with recurrent episodes of wheezing, shortness of breath, chest tightness, and coughing, symptoms that typically vary in intensity and...
Asthma-I: Introduction01:29

Asthma-I: Introduction

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-II: Pathophysiology and Classification01:26

Asthma-II: Pathophysiology and Classification

Asthma is a prevalent chronic respiratory condition marked by inflammation and hyperresponsiveness of the airways. Its pathophysiology involves complex interactions among inflammatory pathways, immune responses, and neural mechanisms.
Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.
Critical processes in asthma pathophysiology include:
