Information for participants

If your child is part of the HealthNuts study we'd like to thank you for taking the time to contribute to this valuable research.

As you may recall, HealthNuts is a ground breaking study of food allergy in children. We first met you at your local immunisation centre when your child was 12 months old. Beginning in 2007, 5,300 infants across Melbourne were tested for food allergy. Around 1,000 came to the HealthNuts clinic at The Royal Children's Hospital for further allergy testing.

Age 4 year old phase

We re-contacted families as children turned four years old and asked parents to fill out a questionnaire.

Age 6 year old phase

At age 6 years, we invited all HealthNuts children to have a free allergy health check. We also asking parents to fill out a short questionnaire. 

Age 10 year old phase

We followed up participants again as they turned 10 years of age. This again involved a free allergy health check for children, and parents and children were asked to fill out a short questionnaire.

Thank you to the parents and children who completed their questionnaire, and the children who had an allergy check  - we really appreciate your help!

Age 15 year old phase

We are excited to announce that we have secured funding to again follow up HealthNuts participants at 15 years of age! 


We'd like all HealthNuts participants to take part, even if they don't have any allergies. If your child doesn't have any allergies, we'd like to find out why!
