Codes and Frequencies
For sample adults, PORKTP reports the time unit (day, week, month, or year) that corresponds with the frequency with which the person reported eating pork. PORKTP should be used in conjunction with PORKNO, which reports the corresponding frequency stated by the person. For information about the portion size, see PORKSIZ.
In 2010, the variable REDMEATMNO was introduced, which reports how many times the person ate red meat, such as beef, pork, ham, or sausage.
PORKTP 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.
