Description

For sample adults, OJTP reports the time unit (day, week, month, or year) that corresponds with the frequency with which the respondent reported consuming orange or grapefruit juice. OJTP should be used in conjunction with OJNO, which reports the frequency stated by the respondent. For information about the portion size, see OJSIZ.

OJTP 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

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.
