For sample adults who had seen a practitioner for chelation during the past 12 months (CHEYR) and had told a conventional medical professional about their use of chelation (CHELCONVHP), CHELNURS indicates whether they had reported their use of chelation to a nurse practitioner or physician assistant.

In both 2002 and 2007, interviewers asked, "During the past 12 months, did you let any of these conventional medical professionals know about your use of chelation?" and handed the respondent a card listing several types of conventional health care practitioners. If the answer was affirmative (i.e., a "Yes" response in CHELCONVP), interviewers asked the follow-up question, "Which ones [did you tell]?" and noted, "You may choose more than one."

In both 2002 and 2007, the list of conventional medical professionals included, along with "nurse practitioner/physician assistant":

  • Medical doctor (including specialists) (CHELMD)
  • Dentist (including specialists) (CHELDENT)

In 2007, the list included additional categories of conventional medical professionals:

  • Doctor of Osteopathy (D.O.) (CHELDO)

For more information about the full range of variables related to chelation, including definitions, see CHEYR.


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