Description

For sample adults in 2000 and 2005 who had taken a multi-vitamin during at least 1 month of the past 12 months (VITAMULTV and VITAMULTVMO), VITAMULTVNO reports the number of days (per week or per month) that respondents had taken a multi-vitamin in those months.

In both years, interviewers asked, "During [the/those] month(s), about how many [days [per week]/days per month] did you take multi-vitamins?" VITAMULTVNO must be interpreted in conjunction with VITAMULTVTP, which reports the type of time unit ("days per week," "days per month," or "other") respondents used when answering the question.

Related Variables[show more]

For 2000 only, the National Center for Health Statistics recoded data from VITAMULTVNO and VITAMULTVTP to create two new variables with consistent time units: Number of days per week took a multi-vitamin during the relevant months of the past 12 months (VITAMULTVDWK), and number of days per month took a multi-vitamin during the relevant months of the past 12 months (VITAMULTVDMO). VITAMULTVDMO is also available for 1992, when it was asked as a direct question.

Variables similar to VITAMULTVNO are available for the following vitamin/mineral supplements (with years indicating availability):

Beta carotene (VITABETANO, 2005)

Calcium (VITACALCNO, 2000, 2005)

Vitamin A (VITAMINANO, 2000)

Vitamin C (VITAMINCNO, 2000)

Vitamin E (VITAMINENO, 2000, 2005)

Selenium (VITASELNNO, 2005)
