Description
For sample adults ages 18 and older, GREENSNO reports the frequency with which the respondent ate mustard greens, turnip greens, or collards in the past year. GREENSNO should be used in conjunction with GREENSTP, which reports the corresponding time unit stated by the respondent. Researchers may also want to use GREENSSIZ, which reports the corresponding portion size.
GREENSNO 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.
