Study type | Observational |
The purpose of this research study is to study the relationship between childhood asthma, allergies, and early-life environmental factors that may cause childhood asthma and allergies. Previous birth cohort studies have found early-life environmental factors such as allergies, pollutants, viruses and bacteria have all contributed to the development of asthma and allergies. Investigators are doing this research because there continues to be a strong need to understand the root causes of asthma and allergies. The CANOE study is an observational cohort study, which means investigators are not asking participants or participant's child to change their medications and investigators will not be giving participants or participant's child a study drug.

Primary | Number of children with early aeroallergen sensitization | Number of children with early aeroallergen sensitization will be reported. Early aeroallergen sensitization, defined as sensitization to at least one aeroallergens by age 2 years. | 2 years | |
Secondary | Number of children with Atopic dermatitis (AD) | Number of children with AD will be reported. Atopic dermatitis, defined if at least 1 of the following is present:
Physician diagnosis of eczema/AD (either study physician or other physician by parental report) at any time, Objective SCORAD (SCORing Atopic Dermatitis) = 8 at 1 or more study assessments.
