9996: Not in Universe
9999: Unknown-don't know

Description

For sample adults, PIEYR is a recoded variable that reports frequency with which the respondent consumes pie. A different variable, SWEETSYR, aggregates responses to questions about different types of baked goods to create a variable that allows researchers to compare baked goods consumption across more samples.

PIEYR is part of a series of variables first introduced in 1987 related to food, food knowledge, and cancer. For related variables, please use the IPUMS NHIS search function and drop-down menus.

Comparability

Prior to 2000, respondents were asked to report the frequency with which they ate pie, as well as how often they ate other baked goods including doughnuts, cookies, cake, or pastries. Beginning in 2010 baked goods were instead divided between doughnuts, sweet rolls, Danishes, muffins or pop-tarts, and cookies, cake, pie, or brownies. To allow for comparability across years, the two categories available in each sample are aggregated into the single variable SWEETSYR. Researchers interested in the differentiated sweets types should use PIEYR, which reports the number of times the respondent ate pie in one year (for 1987 and 1992), and DONUTYR, which reports the number of doughnuts the respondent ate in one year (for 2010). Data users can divide SWEETSYR by PIEYR or DONUTYR in a given sample to create the proportion of a specific type of sweets.

Prior to 2000, respondents were asked about foods they usually ate in the past year. Beginning in 2000, this recall period was reduced to foods the respondent usually ate in the past month. The structure of the responses (recording number of times a food was consumed and the time unit associated with that frequency) makes it possible to compare response categories even with different recall periods

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.
