High prevalence of allergy in North Cypriot children
Insights
Asthma and allergy prevalence is extremely high in North Cyprus children aged 7-12. House dust mite sensitization is a significant risk factor for developing childhood asthma.
Area of Science:
- Pediatric Allergy and Immunology
- Epidemiology of Respiratory Diseases
- Childhood Asthma Research
Background:
- The International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire has been a global standard for asthma prevalence research since 1991.
- Standardized tools are crucial for comparing asthma and allergy data across diverse populations.
Purpose of the Study:
- To evaluate the prevalence of asthma, allergic diseases, and atopy in schoolchildren in North Cyprus.
- To establish baseline data for pediatric allergic conditions in the region.
Main Methods:
- Utilized the ISAAC questionnaire for data collection from parents of 580 schoolchildren (ages 7-12) in Nicosia.
- A subgroup of 97 children underwent skin prick testing (SPT) and lung function testing (LFT) for detailed allergic assessment.
Main Results:
- Identified high prevalence rates: 20.8% for asthma ever, 10% for current wheezing, and 68% for SPT-positivity.
- Atopy was significantly more prevalent in the tested subgroup, with house dust mite (HDM) identified as the most common sensitizing allergen.
Conclusions:
- North Cyprus exhibits exceptionally high rates of asthma, allergic diseases, and atopic sensitization among children aged 7-12.
- HDM sensitization emerges as a key risk factor contributing to the development of asthma in this pediatric population.
Background:
The ISAAC (the International Study of Asthma and Allergies in Childhood) questionnaire has been used to standardize research on the prevalence of asthma in children since 1991.
Aim:
In this Phase I study, the prevalence of asthma, other allergic diseases and atopy was evaluated in North Cyprus.
Methods:
The ISAAC questionnaire was distributed to grades I-V schoolchildren. Data were obtained from parents of 580 schoolchildren aged between 7 and 12 years attending a primary school in Nicosia, the capital of North Cyprus. Of those, a sub-group of 97 (16.7%) randomly selected children were evaluated by skin prick test (SPT) and lung function test (LFT).
Results:
The prevalence rates of asthma ever, current wheezing and SPT-positivity were 20.8%, 10% and 68%, respectively. The prevalence of atopy was significantly higher in the randomly selected subgroup of 97 (68%) patients subjected to SPT and LFT, and the house dust mite (HDM) was the allergen to which children were most frequently sensitized.
Conclusions:
In northern Cyprus, the prevalence rates of asthma, allergic diseases and atopic sensitization in 7-12-year-old children are extremely high. Sensitization to HDM is a risk factor for the development of asthma.
