IgG1 antibody levels to cat and IgG4 antibody levels to \u03b2\u2010lactoglobulin and cat were also higher in atopic than in nonatopic mothers, whereas the other subclass antibody levels to those allergens were similar. High levels of cord blood IgG antibodies to cat and birch, but not to the food allergens, were associated with less atopic symptoms in the children during the first 8 years of life. Moreover, children who developed IgE antibodies to cat had lower levels of IgG antibodies to that allergen at birth.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>High levels of cord blood IgG subclass, especially IgG4, antibodies to food and inhalant allergens are associated with maternal atopy.
