1 Dietary intake data are presented as mean (95% CI); 2 Total choline intakes were estimated assuming that water-soluble forms of choline contribute 84% to total choline and a reference milk intake of 780 mL/day; 3 Total choline intakes were estimated at 36 weeks of gestation using a food frequency questionnaire and the USDA database on choline content in common foods (version 2); 4 Since the AI reflects the average choline concentration of breastmilk from healthy lactating women, it is expected that ~50% of infants would have intakes above the AI. When mean intake equals the AI, it is assumed that the prevalence of inadequacy in the group is low; when mean intake is below the AI, no conclusions regarding adequacy can be drawn.
