Codes and Frequencies
For sample persons aged 18 years and over, EHEARFIBER indicates whether the respondent indicated that she/he had heard of fiber.
In 1992, respondents who identified eating more fiber as helpful for reducing the risk of certain types of cancer (EHCANFIBER), and were not asked directly if they had heard of fiber, but were automatically documented as having heard of fiber.
EHEARFIBER is part of a series of variables initiated in 1987 dealing with food, food knowledge, and cancer. For related variables, please use the IPUMS NHIS search function and drop-down menus or see DIETCHANGEV.
