^aThe proportion (%) of sodium consumed is defined as the sum of the amount of sodium consumed from each specific food category for all participants divided by the sum of sodium consumed from all food categories for all participants multiplied by 100. All estimates use 24-hour dietary recall, take into account the complex sampling design, and use dietary Day 1 sample weights to account for nonresponse and weekend/weekday recalls.

^bA measure that accounts for differences in the amount of calories consumed from foods obtained from each source, defined as milligrams of sodium/1,000 kcal.

^cPlace obtained was analyzed from responses to the questions, “Where did you get this (most of the ingredients for this) [food name]?” Sources other than those shown were combined under “other” and included “from someone else/gift,” and 19 other sources, including “missing,” “do not know,” and “other/specify.”

^dDifference compared with respondents aged 14 to 18 years.

^eDifference compared with children aged 6 to 10 years.
