a
Adjusted for cohort, maternal age, maternal pre-pregnancy BMI, child sex, maternal education level, maternal race/ethnicity, parity, income, prenatal vitamin use
b
As defined in text; low total pregnancy intake corresponds to low or no intake at both time points; inconsistent intake refers to high intake in one timepoint and low in the other; high intake refers to consistently high intake across both pregnancy timepoints
c
For fish type analyses, reference category for each estimate is individuals reporting no intake of that type of fish (any intake during the survey period compared to no intake)
