Model 1. Adjusted for visit (early or mid childhood) and measurement conditions

Model 2. Model 1 + maternal age, race/ethnicity, education, marital status, pre-pregnancy BMI, smoking during pregnancy, third trimester SBP and child age, sex, fetal growth z-score, and BMI z-score.

Model 3. Model 2 + maternal second trimester fish intake

Model 4. Model 2 + maternal second trimester DHA + EPA intake
