Description

For sample adults, YAMTP reports the time unit (day, week, month, or year) that corresponds with the frequency with which the respondent reported eating sweet potatoes or yams. YAMTP should be used in conjunction with YAMNO, which reports the corresponding frequency stated by the respondent.

YAMTP is part of a series of variables related to food, food knowledge, and cancer. For related variables, please use the IPUMS NHIS search function and drop-down menus.

Comparability

Beginning in 2010, sweet potatoes are included with other types of potatoes (POTATONO).

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.
