Description
For sample adults in 2002 and 2007 who had ever seen a practitioner for chelation (CHEEV) and for sample children in 2007, CHEYR reports whether the person had used chelation in the past 12 months.
Chelation was one of many alternative health treatment modalities included in the 2002 and 2007 Alternative Health Supplements. For the full list of alternative health treatments covered in the NHIS, and for general background information about the Alternative Health Supplements, see ACUYR.
Definitions
The 2002 and 2007 Field Representative's Manuals provide similar definitions of chelation. The 2007 manual says that chelation is:
In 2002 the definition was not routinely shared with respondents. However, in 2007 field representatives were advised to "feel free to offer [this definition] even if the respondent has not requested [it]."
The 2002 and 2007 survey questions asked whether the person had seen "a practitioner" (for sample adults) or "a provider or practitioner" (for sample children) for chelation in the past 12 months. The 2007 Manual defines an "alternative provider or practitioner" as:
Related Variables
In 2002 and 2007, sample adults with a positive response in CHEYR were asked a series of other questions (described below) about the following topics: frequency of using chelation; the out-of-pocket cost of the treatment; whether chelation was used to treat a specific medical condition, and, if so, what that condition was (this information was also obtained for sample children in 2007); any conventional medical treatments received and the timing of the conventional treatment relative to the chelation treatment; the reasons for using chelation; and the disclosure of the use of chelation to conventional medical professionals.
Respondents who indicated that they had ever used chelation (CHEEV) (in the case of sample adults) and that they had used it in the last 12 months (CHEYR) (both sample adults and sample children), were asked follow-up questions about their use of chelation. Most of the following variables relate only to sample adults, except for CHETREAT and some variables covering specific health conditions.
- importance of use of chelation (CHEIMPORT)
- times saw practitioner for chelation (CHENO)
- amount paid per visit for chelation (CHEPAID)
- chelation costs covered by insurance (CHEINSURE)
- whether used chelation for specific health problem (CHETREAT)
- reasons for using chelation (CHEUSCOMBO, CHEUSENERGY, CHEUSHCREC, CHEUSIMMUN, CHEUSINTER, CHEUSMEDCOST, CHEUSMEDFAIL, CHEUSRELREC, CHEUSWELL)
- whether combined chelation with conventional treatments (CHENOCONV, CHECOUN, CHENPMED, CHEPMED, CHEPT, CHESURG)
- timing of chelation treatment, relative to use of conventional treatments (CHECOUNTIM, CHENPMEDTIM, CHEPMEDTIM, CHEPTTIM, CHESURGTIM)
- whether informed conventional medical practitioners of use of chelation (CHELCONVHP, CHELDENT, CHELDO, CHELMD, CHELNURS, CHELPHARM, CHELPSYCHI, CHELPSYCHO)
Persons who indicated in CHETREAT that they had used chelation in the past 12 months to treat a specific health problem were asked to specify the condition treated. There are 131 total variables for specific conditions that were treated by chelation, including 72 for sample adults, 28 for sample children, and 31 for both sample adults and sample children. See CHETREAT for more detail and the full list of conditions that persons could indicate were treated with chelation. Analysts interested in the conditions that chelation was used to treat may also wish to consult the following variables:
- condition for which chelation was used most (CHETCONMOST)
- first condition for which chelation was used (CHECON1)
- degree of help from chelation, 1st condition (CHECON1HELP)
- second condition for which chelation was used (CHECON2)
- degree of help from chelation, 2nd condition (CHECON2HELP)
- third condition for which chelation was used (CHECON3)
- degree of help from chelation, 3rd condition (CHECON3HELP)
- condition count for chelation (CHECONNO)
Comparability
CHEYR is fully comparable across time. In the 2002 and 2007 sample adult questionnaires, the question read, "During the past 12 months, did you see a practitioner for chelation?" The 2007 sample child questionnaire asked, "During the past 12 months, did [fill: sample child's name] see a provider or practitioner for any of the following therapies? Please say yes or no to each. ... Chelation (key-LAY-shun) Therapy?"
Universe
- 2002: Sample adults age 18+ who have ever seen a practitioner for chelation therapy.
- 2007: Sample adults age 18+ who have ever seen a practitioner for chelation therapy and sample children under 18.
