Codes and Frequencies
For sample adults ages 18 and older, GRAPFRTP reports the time unit (i.e., day, week, month, or year), which corresponds with the frequency with which the respondent reported eating grapefruit in the past year. GRAPFRTP should be used in conjunction with GRAPFRNO, which reports the corresponding frequency stated by the respondent. Researchers may also want to use GRAPFRSIZ, which reports the corresponding portion size.
GRAPFRTP 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.
