Description
For sample adults in 2000 who had taken vitamin C during at least 1 month of the past 12 months (VITAMINCMO), VITAMINCDWK reports the number of days per week the respondent had taken vitamin C in those months.
The National Center for Health Statistics (NCHS) used the information recorded in two separate variables--one reporting the time period selected by the respondent (VITAMINCTP), and the other reporting the number of days per week or per month reported (VITAMINCNO)--to create the new recoded variable VITAMINCDWK with a single time unit of times per week. VITAMINCTP and VITAMINCNO record responses to the question, "During {the/those} month(s), about how many {days [per week]/days per month} did you take vitamin C?"
Related Variables[show more]
The NCHS also used data from VITAMINCTP and VITAMINCNO to create a second recoded variable with a single time unit, VITAMINCDMO, which reports the number of days per month respondents had taken vitamin C during the relevant months of the past 12 months. VITAMINCDMO is also available for 1992 and 1987, when it was asked as a direct question.
Variables similar to VITAMINCDWK are available for the following vitamin/mineral supplements (for 2000 only):
- Calcium (VITACALCDWK)
- Vitamin A (VITAMINADWK)
- Vitamin E (VITAMINEDWK)
- Multi-vitamins (VITAMULTVDWK)
