Codes and Frequencies
For sample adults, LIVERSIZ reports the person's average portion size (small, medium, or large) when consuming liver, including chicken liver. A medium portion size was defined as 4 ounces. Researchers may wish to use LIVERSIZ in conjunction with LIVERNO, which reports the frequency with which the person eats liver, and LIVERTP, which reports the corresponding time unit.
LIVERSIZ 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.
