Description

For sample adults, FOODNOFLAG flags cases where the number of times food is reported as being consumed was coded inconsistently. For example, if the number of times a food consumed was greater than or equal to 1, but the corresponding time unit reported is equal to 0.

FOODNOFLAG 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.

Comparability

Changes in survey design (e.g., quarters in which the supplement was collected) may affect raw frequencies, but do not affect comparability of the variable. As always, data users should use the prescribed IHIS weights.
