Longitudinal birth cohorts and food allergy
| Birth cohort | WHEALS | CCAPS | HEALTHNUTS | PASTURE |
|---|---|---|---|---|
| Geographic location | Southeast Michigan, USA | Greater Cincinnati area, Ohio, USA | Melbourne, Australia | Rural areas of 5 European nations: Austria, Finland, France, Germany and Switzerland |
| Unique characteristics of cohort | Racially diverse with 62% Black race | Higher risk cohort with at least one atopic parent | Used challenge-proven outcomes to assess the role of infantile food allergy in development of asthma | Assessed role of farm animals on allergic disease presence |
| Times of follow-up postnatally | 1, 6, 12, 24 and 48-months of age | 1,2,3,4, and 7 years | 11 or 15 months, 1 year, 4 years | 1, 4, 6 years |
| Total recruited | 1258 | 762 | 5276 | 1133 |
| Food allergens tested | Egg, peanut, milk | Cow’s milk, egg | Egg, peanut, sesame, and cow’s milk or shrimp | Cow’s milk, hen’s egg, cow’s milk, peanut, hazelnut, carrot, and wheat |
| Key food allergy phenotype finding | Black race was a significant risk factor for milk and egg allergy | Food sensitization in the presence of KIF3A mutations poses a significant risk for asthma, independent of aeroallergen sensitization | Asthma at 4 years of age is twice as common in children with food allergy, irrespective of whether child outgrows allergy | Farm exposure can alter sensitization patterns |
| PMIDs for key food allergy articles | 24636082 | 30830718, 19759553 | 29153880, 20608942 | 28531273 |
