Codes and Frequencies
For sample adults, OJSIZ reports the respondent's average portion size (small, medium, or large) when drinking orange or grapefruit juice. A medium portion was defined as 6 ounces. Researchers may wish to use OJSIZ with OJNO, which reports the frequency with which the respondent drank orange or grapefruit juice, and OJTP, which reports the corresponding time unit.
OJSIZ 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.
