Allergies

The term allergy encompasses a wide range of conditions; it is not a disease in itself. The term allergy – medically termed hypersensitivity, signifies an exaggerated reaction to foreign substances.

Old Friends Hypothesis

The "old friends" hypothesis was proposed by Graham Rook in 2003 as an alternative to or refinement of the hygiene hypothesis, originally brought forward by Strachan in 1989 as an explanation for the rise in allergic disease.

Study maps how birth order tracks disease risk across 10 million siblings

Researchers analyzing claims from more than 10 million siblings linked first-born status to higher odds of several neurodevelopmental and allergic diagnoses, while second-born status tracked with substance abuse and gastrointestinal conditions. The observational study identified 150 significant birth-order associations across the phenome, but claims data and residual confounding prevent causal conclusions.
