Description
For sample adults in 2000 and 2005 who had taken any vitamin E during at least 1 month of the past 12 months (VITAMINEMO), VITAMINETP reports the time period ("days per week," "days per month," or "other") respondents used to report how frequently they had taken vitamin E during the relevant months.
In both years, interviewers elicited these responses by asking, "During [the/those] month(s), about how many [days [per week]/days per month] did you take vitamin E?" VITAMINETP must be interpreted in conjunction with VITAMINENO, which reports respondents' answers to the question in terms of number of days.

For 2000 only, the National Center for Health Statistics recoded data from VITAMINENO and VITAMINETP to create two new variables with consistent time units: Number of days per week took vitamin E during the relevant months of the past 12 months (VITAMINEDWK), and number of days per month took vitamin E during the relevant months of the past 12 months (VITAMINEDMO). VITAMINEDMO is also available for 1992, when it was asked as a direct question.
Variables similar to VITAMINETP are available for the following vitamin/mineral supplements (with years indicating availability):
- Beta carotene (VITABETATP, 2005)
- Calcium (VITACALCTP, 2000, 2005)
- Vitamin A (VITAMINATP, 2000)
- Vitamin C (VITAMINCTP, 2000)
- Multi-vitamins (VITAMULTVTP, 2000, 2005)
- Selenium (VITASELNTP, 2005)
