Insights

Paediatric asthma prevalence in Iran was 10.9%, with higher rates in older children, males, and urban areas. Passive smoking was significantly linked to childhood asthma.

Area of Science:

  • Pediatric Pulmonology
  • Epidemiology
  • Public Health

Background:

  • Paediatric asthma is a global health concern, with limited data from developing nations.
  • This study addresses the knowledge gap by assessing asthma prevalence in Iranian children.

Purpose of the Study:

  • To determine the prevalence of asthma and severe asthma in the paediatric population of Iran.
  • To identify risk factors and demographic variations associated with childhood asthma in Iran.

Main Methods:

  • A national cross-sectional study utilizing a randomized multistage stratified cluster sampling method.
  • Involved 16,410 children aged 6-7 and 16,850 aged 13-14, using validated International Study of Asthma and Allergies in Childhood (ISAAC) questionnaires.
  • Data collection occurred between November 2015 and February 2016.

Main Results:

  • Overall paediatric asthma prevalence was 10.9%, higher in older children (13-14 years), males, and urban residents.
  • Severe asthma affected 3.9% of children, predominantly in older males.
  • Passive smoking showed a significant association with asthma in both age groups.

Conclusions:

  • Asthma prevalence in Iranian children is comparable to other developing countries.
  • Targeted interventions in urban areas, for males, and older children are recommended for asthma control.
  • Further national surveys are needed to monitor paediatric asthma trends in Iran.

Surveys

Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

Prevalence and Incidence01:08

Prevalence and Incidence

In statistical epidemiology and health sciences, two essential metrics—prevalence and incidence—are fundamental for understanding disease dynamics within a population. These measures enable public health officials, epidemiologists, and researchers to assess the burden of diseases, allocate resources effectively, and design impactful public health policies and interventions.
Prevalence indicates the proportion of individuals in a population who have a specific disease or health...

Introduction to Surveying, Plane Surveying and Geodetic Surveys

Surveying is the art and science of mapping the earth's surface. It involves measuring distances, angles in horizontal or vertical directions, and levels to understand the shape and size of land features. Surveying techniques are essential for various tasks, such as identifying the levels of a land area with reference to a specific point, and mapping undulations and water bodies.There are two main types of surveying: plane surveys and geodetic surveys. Plane surveys assume the earth is flat,...
