Codes and Frequencies
For sample adults in 2002 who had ever used vitamins for their own health or treatment (VITEV), VITMULTEV indicates whether the person had ever taken "multi-vitamins such as One-A-Day."
Persons with an affirmative response to VITEV were asked, "Which of the following did you use? Please say yes or no to each one." In addition to reporting that they had ever used multi-vitamins, sample adults could also report that they had ever used:
- Individual vitamin supplements (VITSUPEV)
- High dose or megavitamin therapy (VITMEGAEV)
Regardless of their response to VITMULTEV, only sample adults who provided an affirmative response to VITMEGAEV were asked further questions about their vitamin use in 2002.
