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.

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...

Obesity

The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in...

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:

Regression Toward the Mean

Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when...

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.
