Codes and Frequencies
For sample adults, WHIBREDTP reports the time unit (day, week, month, or year) that corresponds with the frequency with which the person reported eating "white bread, rolls or crackers, including sandwiches, bagels, and so forth." WHIBREDTP should be used in conjunction with WHIBREDNO, which reports the corresponding frequency stated by the person. For information about the portion size, see WHIBREDSIZ.
WHIBREDTP 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.
