For sample persons ages 18 and over, BUYLOWSALT reports how the sample person or the person who usually shops for the sample person's food bought items that are labeled "low sodium" or "low salt." Respondents could answer always, often, sometimes, rarely, or never. For 1995 forward, respondents could also reply "don't shop for food".

BUYLOWSALT 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.


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.

Changes in response options may compromise comparability between 1991-1993 and 1995-forward.
