Data presented as change in relative risk per 10 nmol/l change in maternal serum 25-hydroxyvitamin D status at 34 weeks’ pregnancy.

Adjusted models: atopy age 1 year - child’s gender, parents’ social class, maternal atopy; atopy age 3 years - child’s gender, exposure to smoke in infancy, maternal eczema, atopy age 6 years - child’s age at testing, child’s gender, parents social class, maternal asthma, paternal rhinitis, maternal atopy; exhaled nitric oxide - child’s age at testing, maternal asthma, paternal rhinitis, maternal height.
