For sample adults in 2000 who had taken a multi-vitamin during at least 1 month of the past 12 months (VITAMULTV and VITAMULTVMO), VITAMULTVDWK reports the number of days per week the respondent had taken a multi-vitamin 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 (VITAMULTVTP), and the other reporting the number of days per week or per month reported (VITAMULTVNO)--to create the new recoded variable VITAMULTVDWK with a single time unit of times per week. VITAMULTVTP and VITAMULTVNO record responses to the question, "During {the/those} month(s), about how many {days [per week]/days per month} did you take multi-vitamins?"

Related Variables 

The NCHS also used data from VITAMULTVTP and VITAMULTVNO to create a second recoded variable with a single time unit, VITAMULTVDMO, which reports the number of days per month respondents had taken a multi-vitamin during the relevant months of the past 12 months. VITAMULTVDMO is also available for 1992 and 1987, when it was asked as a direct question.

Variables similar to VITAMULTVDWK are available for the following vitamin/mineral supplements (for 2000 only):
