The allergic phenotype during the first 10 years of life in a prospective cohort.

Allergic eczema/asthma in early life, being born during the autumn/winter, having multiple allergic symptoms and two allergic parents were all strong predictors for having allergic diseases at 5 and 10 years of age. However, the allergic march seems to be independent of heredity, as IgE-mediated allergies follow the same trajectories in children with and without allergic heredity.
