Description

YTQTBACPAIN indicates whether the person used yoga, Tai chi, or Qi gong to treat back pain or problem. Please see the Comparability and Universe tabs for more information on how this variable is constructed and changes over time.

Comparability

Prior to 2012, in universe persons were asked about a series of specific health problems, symptoms, or conditions they may have treated with different complementary and alternative medicine (CAM) therapies. Beginning in 2012, persons were instead asked to select three of sixteen therapies that were most important and only asked the series of questions related to treating health problems, symptoms, or conditions about these top three therapies. Persons who did not include yoga/tai chi/qi gong among their top three CAM therapies did not answer follow up questions for this therapy beginning in 2012 and are reported as responding "no". For more information on the construction of this variable for 2012-forward, please see TABDOM1.

Additionally, prior to 2012 only sample adults could report treating back pain using a CAM therapy. However, beginning in 2012, "low back pain" was included on the list of conditions that sample children could report treating using a CAM therapy.
