Independent§ associations (adjusted‡)

Fish	0.44 (0.21 to 0.93)	0.34 (0.13 to 0.85)

*Regression coefficient estimated modelling food intake as a continuous variable (g/day or natural log of g/day), and OR presented for the difference in mean intake (in g/day) between the highest and lowest tertiles of intake (for mean food intake per tertile see table 2).

†Dietary variable modelled as natural log of g/day.

‡Adjusted for educational level of the mother, foreign descent, and total energy intake.

§The variables representing whole grain intake and fish intake were entered simultaneously in a single logistic model.
