- Brief Summary
The present study is a 5-year follow-up of the Allergy Reduction Trial (A.R.T.) birth cohort study of 551 infants at high-risk for allergy. The A.R.T. 5-year follow-up study, aims to investigate the prolonged effect of each feeding regimen \[formula-fed (exclusively or partially) with the partially hydrolyzed formula (pHF) or the standard formula (SF), or exclusively breastfed\] within the first 6 months of life on the development of any allergic manifestations up to the age of 5 years. Allergic manifestations within this time period will include the presence of any of the following: atopic dermatitis, food allergies, respiratory allergies, urticaria, drug allergy and insect venom allergy. In addition, differences on growth (weight, height, BMI) will be examined.
