Fully adjusted associations between dietary pattern trajectories from (6 to 24 months) and IQ¹ at 8 and 15 years of age (n = 7652)².

1Abbreviations: FSIQ, full scale intelligence quotient; IQ, intelligence quotient; PIQ, performance intelligence quotient; VIQ, verbal intelligence quotient 2Eligible participants were children who had at least one measurement of IQ collected at either 8 or 15 years of age (n = 7652). IQ was measured using the Wechsler Intelligence Scale for Children at 8 years and the Wechsler Abbreviated Scale of Intelligence at 15 years of age. Incomplete IQ or missing covariable data was imputed by Multiple Imputation. 3Analyses show the beta-coefficient from multivariable linear regression analysis using generalized linear models and adjusted for the following covariables; sex, gestational age at birth, birth weight, ethnicity, singleton/twin, maternal age, parity, social class (according to standard UK classifications of occupation at the time of birth[17]), maternal education, other children, family income, maternal smoking, stimulation in the home environment (using an adaptation of the HOME questionnaire[18]) and maternal IQ (measured by WASI when the study child was 15 years of age). A one standard deviation change in Healthy dietary pattern trajectory from 6 to 24 months of age is associated with 0.66 (95% CI −0.20, 1.51) higher FSIQ scores at 8 years of age.
