TABLE 2.

Interactions between the effects of maternal macronutrient intake in trimester 1 (adjusted for total energy intake by the nutrient density method) and fetal sex on adjusted ORs for SGA birth¹

		P
Dietary intakes	P-interaction(dietary intake × fetal sex)	Dietary intake	Fetal sex
Energy, per 100 kcal/d	0.62	0.91	0.35
Carbohydrate, per 5% of energy	0.09	0.72	0.12
Protein, % of energy	0.92	0.88	0.79
Fat, per 5% of energy	0.05	0.71	0.03

¹ n = 2035. Multiple variable logistic regression was used with maternal age, education, parity, height, and weight at recruitment; fetal sex; and total energy intake as covariates. SGA, small-for-gestational age.
