Codes and Frequencies
For sample adults, DARBREDSIZ reports the respondent's average portion size (small, medium, or large) when eating whole grain bread. A medium portion was defined as 2 slices. Researchers may wish to use DARBREDSIZ in conjunction with BREADNO, which reports the frequency with which the respondent ate whole grain bread and BREADTP, which reports the corresponding time unit.
DARBREDSIZ 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.
