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: FEV1 absolute - child’s age at testing, child’s gender, parity, maternal BMI, maternal height; FEV1 z-score - child’s gender; FVC absolute - child’s age at testing, child’s gender, age at introduction of solid foods, maternal BMI, maternal height, FVC z-score - child’s gender; BHR - maternal age, smoking in pregnancy, paternal eczema, age at introduction of solid foods.
