Description

For sample adults, YAMNO reports how many times the respondent consumed sweet potatoes or yams in a specified time period. YAMNO should be used in conjunction with YAMTP, which reports the corresponding time unit stated by the respondent.

YAMNO 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.

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.
