Adjusted associations maternal secretor status with (A) likelihood of infections in the second year of life and (B) change in child body mass index (BMI) amongst non-secretor infants. Results are shown as odds ratios (AD), risk ratios (infections), and β estimates (BMI) with 95% CI. Models adjusted for child sex, maternal allergy (AD only), delivery mode (infections only), maternal milk group and/or ABO blood group, birthweight, and gestational age. Bonferroni-adjusted significance threshold: α = 0.0035. Abbreviations: AD, atopic dermatitis; OM, otitis media; LRTI, lower respiratory tract infections; URTI, upper respiratory tract infections; BMI, body mass index; CI, confidence interval; FUT2, fucosyltransferase-2; SNP, single nucleotide polymorphism; HMO, human milk oligosaccharide; SPATZ, Ulm SPATZ Health Study; UBCS, Ulm Birth Cohort Study.
