Codes and Frequencies
HER2USHCREC indicates whether respondents had used a second herbal supplement because it was recommended by a health care provider. Please see the Comparability and Universe tabs for important information on changes that may affect the comparability of this variable over time.
For other reasons for using a second herbal supplement, see HER2USWELL. For information about the full range of variables related to natural herbs, including a definition of "natural herbs," see HERYR.
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 a second herbal supplement among their top three CAM therapies did not answer follow up questions for this therapy beginning in 2012 and are reported as responding no.
Additionally, sample children aged 4-17 are included in the universe beginning in 2012. Otherwise, there are no comparability issues.
