^a,bMeans within an age group and sex category (all, male, female) that do not share a common superscript letter differ significantly, p < 0.05 (Bonferroni-adjusted p < 0.0167)
^cValues are weighted mean ± SE (data from CCHS 2.2). Adjusted for age, sex, race, supplement use, food security, language spoken at home, physical activity category, smoking, education level and marital status. None = no food or beverages reported as breakfast; RTEC Breakfast = breakfast that included ready-to-eat cereal (RTEC); Other Breakfast = any other type of breakfast
