Multivariate-adjusted ORs (95%(CIs) of children’s T-score ≥ 65 for CPRS-R:S subscales at age 7 years associated with maternal log-SF and Hb levels (continuous). *Models were adjusted for cohorts (Gipuzkoa, Sabadell, Valencia), maternal age (years), maternal pre-pregnancy BMI (kg/m²), social class (low, medium, high), smoking during pregnancy (yes, no), mode of delivery (eutocic, dystocic), parity (primiparous, multiparous) breastfeeding (months), total iron intake above the RDA (27 mg/d) in 2^nd period (yes, no), children’s sex (male, female), age at delivery (weeks), birth weight (kg), birth head circumference (cm), children’s age at time of test (years) and BMI-for-age z-score at age 7 years, log-SF levels in 1^st period (μg/L) (for Hb analyses) and Hb levels (for SF analyses). †FS measurements at first and second trimester as a whole were defined as first period of pregnancy. The diamonds represent OR and the whisker plots represent 95% CIs.
