Codes and Frequencies
For sample adults ages 18 and older who ate grapefruit in the past year, GRAPFRSIZ reports the size of the portion consumed (small, medium, or large). A medium portion was defined as ½ of a grapefruit. Researchers may wish to use GRAPFRSIZ in conjunction with GRAPFRNO, which reports the number of units of grapefruit consumed and GRAPFRTP, which reports the corresponding time period
GRAPFRSIZ 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.
