Codes and Frequencies
For sample adults, WHIBREDSIZ reports the person's average portion size (small, medium, or large) when eating white bread, rolls, or crackers. A medium portion was defined as 2 slices or four crackers. Researchers may wish to use WHIBREDSIZ in conjunction with WHIBREDNO, which reports the frequency with which the respondent ate white bread and WHIBREDTP, which reports the corresponding time unit.
WHIBREDSIZ is part of a series of variables initiated in 1987 related to food, food knowledge, and cancer. For related variables, please use the IPUMS NHIS search function and drop-down menus.
