FRUTNO is a 3-digit-numeric variable.
996: Not in Universe
998: Unknown-not ascertained
999: Unknown-don't know
For sample adults, FRUTNO reports how many times the respondent ate fruit in a specified time period. This includes fresh, frozen, or canned fruit, but does not include fruit juice. FRUTNO should be used in conjunction with FRUTTP, which reports the corresponding time units stated by the respondent.
FRUTNO is part of a series of variables initiated in 1987 related to food, food knowledge, and cancer.
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 beginning in 2000 excluding 2005 (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, and this data is available in the variable FRUITMO. 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 IPUMS NHIS weights.
- 1992: Half of sample persons age 18+ in quarters 1 and 2 and 2 weeks of quarter 3 (excluded from CACT supplement).
- 2000; 2010; 2015: Sample adults age 18+.
