Description

For sample adults who had used high dose or megavitamin therapy (2002) or had taken vitamin or mineral supplements (2007) during the past 12 months (VITYR and VITANY) and had told a conventional medical professional about their use of high dose/megavitamin therapy or vitamin/mineral supplements (VITYLCONVHP), VITYLNURS indicates whether they had reported their use of high dose/megavitamin therapy or vitamin/mineral supplements to a nurse practitioner or physician assistant.

Data Collection

In 2002, interviewers asked, "During the past 12 months, did you let any of these conventional medical professionals know about your use of high dose or megavitamin therapy?" In 2007, the question was nearly identical but referred to "vitamins" rather than "high dose or megavitamin therapy." In both years, the interviewer then handed the respondent a card listing several types of conventional health care practitioners. If the answer was affirmative (i.e., a "Yes" response in VITYLCONVHP), interviewers asked the follow-up question, "Which ones [did you tell]?" and noted, "You may choose more than one."

Comparability

Only sample adults with a positive response in VITYLCONVHP are included in the question universe for VITYLNURS. For discussion of comparability issues for VITYLCONVHP, see the documentation for that variable.
