Description

For sample adults, MAYOSIZ reports the respondent's average portion size (small, medium, or large) when eating mayonnaise or salad dressing. A medium portion was defined as 2 tablespoons. Researchers may wish to use MAYOSIZ in conjunction with MAYODRNO, which reports the frequency with which the respondent ate mayonnaise or salad dressing, and MAYODRTP, which reports the corresponding time unit.

MAYOSIZ 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

Special instructions in the field representative's manual differ slightly between survey years. The 1992 field representative's manual indicates that respondents should include low-fat or non-fat dressings or mayonnaise; however, all other survey years specify not to include these. Beginning in 2000, interviewers were instructed to also include salad dressing used as dip.s

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.
