A study of 778 children born in the Australian Capital Territory examined the clinical features of peanut allergy over 13 years:
- Most peanut allergy (90%) developed by age 72 months.
- Later age of first reaction was associated with an increased risk of anaphylaxis.
- Asthma was associated with increased risk of anaphylaxis.
- The incidences of peanut allergy and sensitization by age 72 months were 1.15% and 1.53%, respectively
- There was a rise in incidence during the 13-year study period.
