Data derived from a single 24-hour dietary recall. Egg consumers (n = 111) and Non-consumers (n = 123) during the previous day. Energy adjustment was calculated dividing each nutrient by the total energy intake in kcal.
Values represent the percent of the sample falling within each tertile. Tertiles were constructed based on the energy-adjusted nutrient and its normal distribution. Categories reported as percent distribution. Cut-off points: Vitamin K (phylloquinone): Tertile 1 = 0 thru .012, Tertile 2 = .012 thru .023, Tertile 3 = .023 thru .19; Vitamin E (alpha tocopherol): Tertile 1 = 0 thru .002, Tertile 2 = .002 thru .003, Tertile 3 = .003 thru .011; Selenium: Tertile 1 = 0 thru .048, Tertile 2 = .048 thru .057, Tertile 3 = .057 thru .099; Beta-carotene: Tertile 1 = 0 thru .21, Tertile 2 = .21 thru .70, Tertile 3 = .70 thru 46; Lutein and xeaxanthin: Tertile 1 = 0 thru .25, Tertile 2 = .25 thru .49, Tertile 3 = .49 thru 2.7; Cholesterol: Tertile 1 = 0 thru .085, Tertile 2 = .085 thru .18, Tertile 3 = .18 thru .54; PUFA: Tertile 1 = 0 thru .005, Tertile 2 = .005 thru .007, Tertile 3 = .007 thru .023; DHA: Tertile 1 = 0 thru .000005, Tertile 2 = .000005 thru .00002, Tertile 3 = .00002 thru .0003.
Chi-square cross-tabulation bivariate analyses were used to compare the energy adjusted nutrient distribution between egg consumers and non-consumers (two-tailed). Nutrient contribution from prenatal supplements not included.
