Codes and Frequencies
For sample adults ages 18 and older who ate mustard greens, turnip greens, or collards in the past year, GREENSSIZ reports the size of the portion consumed (small, medium, or large). A medium portion was defined as ½ cup. Researchers may wish to use GREENSSIZ in conjunction with GREENSNO, which reports the number of units of greens consumed and GREENSTP, which reports the corresponding time period
GREENSSIZ 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.
