For sample adults, FRUTWK is a recoded variable that reports how many times per week the respondent consumed fruit. This recoded variable is based on the responses to FRUTNO, which reports the frequency with which the respondent ate fruit and FRUTTP, which reports the corresponding time units. This includes fresh, frozen, or canned fruit, but does not include fruit juice.

FRUTWK 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.


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. In 2005, this format of separate frequency and time units was not used; instead respondents' answers were organized into pre-defined categories. Researchers interested in using all years of available data may consider seeing the 2005 variable FRUITMO, and modifying FRUTNO and FRUTTP to correspond to the pre-defined categories from 2005.

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.
