Trans-generational effects: exposures before conception & offspring risk of asthma and allergies

We aim to establish whether pre-conception exposure to allergens, proxy markers of lower microbial diversity (e.g. lack of exposure to farming and infections), chemicals (e.g. tobacco smoke, occupational exposures), metabolic risk markers (e.g. obesity, diet) and parental disease phenotypes (e.g. severity of asthma and immune markers) increase the risk of asthma and allergies in offspring independent of post-conception exposures.
There is emerging evidence, mainly from animal studies, that asthma and allergy may result from exposures before conception. If pre-conception exposures are important in the development of asthma and allergies, it is a "game changer" in this area, as it may:
- Lead to novel interventions
- Explain the inconsistent evidence on post-conception risk factors (possible confounding by pre-conception risk factors)
- Explain the failure of intervention trials directed at the post-conception perioud.
Our study is part of Respiratory Health In Nothern Europe, Switzeland, Spain and Austalia (RHINESSA) project, an international research project investigating lung health in the offspring of the prestigious European Community Respiratory Health Survey (ECRHS) participants in 11 centres in Northern Europe, Spain, Switzerland, and Australia. Our international study will be the world's first to use the life course approach to identify pre-conception risk factors for asthma and allergies in children and adults.
