Description
For sample adults, FOODSIXBFLAG flags cases with a valid observation for the number of times a food was consumed per year, but where the portion size for that food was left blank.
FOODSIXBFLAG 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 or see DIETCHANGEV.
