Insights
Birth season impacts rhinitis risk. Spring births showed higher rhinitis prevalence in young adults. Avoiding spring births and maintaining a healthy weight may reduce chronic rhinitis risk.
Area of Science:
- Epidemiology
- Environmental Health
- Allergy and Immunology
Background:
- Rhinitis, a common condition affecting nasal passages, can be recurrent or chronic.
- Factors influencing rhinitis prevalence are complex and may include environmental exposures.
- The potential impact of season of birth on rhinitis development warrants investigation.
Purpose of the Study:
- To investigate the association between season of birth and the prevalence of rhinitis.
- To identify specific birth seasons linked to increased rhinitis risk.
Main Methods:
- Retrospective analysis of medical records from 1.1 million Israeli army conscripts (17-year-olds).
- Comparison of rhinitis prevalence across different birth seasons.
- Multivariate analysis incorporating BMI, cognitive score, and maternal birthplace.
Main Results:
- Overall rhinitis prevalence was 7.1% in males and 5.3% in females.
- A statistically significant association (p < 0.001) was found between birth season and rhinitis prevalence.
- Spring births were associated with the highest rhinitis prevalence in both genders.
- Increased odds of rhinitis were linked to BMI > 25, higher cognitive scores, and non-Israeli/African maternal birthplace.
Conclusions:
- Young adults born in spring exhibit an elevated risk of developing rhinitis.
- Overweight status and higher cognitive scores are also associated with increased rhinitis risk.
- Strategies such as avoiding spring births and managing weight may mitigate chronic rhinitis incidence.
Aim:
To explore the relationship between the season of birth and the prevalence of recurrent or chronic rhinitis (rhinitis).
Methods:
The medical records of consecutive 17-year-old conscripts to the Israeli army were reviewed. We compared the prevalence of rhinitis between children born during different seasons. Multivariate analysis was performed with additional variables.
Results:
The prevalence of rhinitis among the 1.1 million recruits was 7.1% in males and 5.3% in females. The association between birth season and the prevalence of rhinitis was highly significant (p < 0.001 for both genders). Spring was the birth season with the highest prevalence of rhinitis (7.4% in males and 5.5% in females). Males born in the winter and females born in the autumn had the lowest prevalence of rhinitis (6.7%, and 5.2% respectively). There was an increased odds ratio for rhinitis among those with a body mass index above 25, higher cognitive score and maternal birth country out of Israel or Africa.
Conclusions:
There was an increased risk of rhinitis among young Israeli adults who were born in the spring, were overweight and had a higher cognitive-score. Family planning to avoid a spring birth and preventing overweight may reduce the risk of chronic rhinitis.

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.
