Insights

The prevalence of asthma in Iranian children and adolescents is 6% and 8%, respectively. Wheezing is the most common symptom, while sleep disturbance is the least common, indicating a need for continued prevention strategies.

Area of Science:

  • Pediatrics
  • Public Health
  • Epidemiology

Background:

  • Asthma is a significant cause of hospitalization in young children.
  • Understanding asthma prevalence in Iranian children is crucial for public health planning and family education.
  • This study addresses the need for current data on pediatric asthma in Iran.

Purpose of the Study:

  • To systematically review and meta-analyze existing studies.
  • To estimate the current prevalence of asthma in Iranian children and adolescents.
  • To inform public health strategies for asthma prevention and control in Iran.

Main Methods:

  • A comprehensive search of international and national databases was conducted until October 2020.
  • Included were cross-sectional and original studies, with quality assessed using the NIH tool.
  • Pooled prevalence was calculated using a random-effects model, with publication bias assessed by Egger's test.

Main Results:

  • 30 studies were analyzed, revealing an overall asthma prevalence of 6% in children and 8% in adolescents.
  • Prevalence was slightly higher in boys (9%) compared to girls (8%).
  • Wheezing was the most frequent symptom (17-19%), while sleep disturbance was the least common (6%).

Conclusions:

  • The prevalence of asthma in Iranian children and adolescents is lower than global averages.
  • Current asthma control and prevention strategies in Iran should be maintained and potentially enhanced.
  • Future guidelines focusing on asthma control and prevention are recommended for the Iranian health sector.

Asthma: Pathogenesis and Management01:20

Asthma: Pathogenesis and Management

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.
