Codes and Frequencies
YTQTAIYR reports whether the person had practiced tai chi in the past 12 months. Please see the Comparability and Universe Tabs for more information on changes to the universe of this variable over time.
Yoga, tai chi, and Qi gong were one of many alternative health treatment modalities included in the Complementary and Alternative Health Supplements. In some years, if persons gave a positive response to YTQTAIYR they were asked a series of follow-up questions.
The 2002 Field Representative's Manual provides the following definition:
This definition was not routinely shared with respondents.
Beginning in 2007, the Field Representative's Manuals provide another definition:
In 2007 and later years, field representatives were advised to "feel free to offer [this definition] even if the respondent has not requested [it]."
Aside from slight changes in the universe, this variable is comparable over time.
In 2002, 2007, and 2012, sample adults 18 and older were first asked whether they had ever practiced tai chi (YTQTAIEV) and, for those who indicated that they had, YTQTAIYR records whether they had practiced tai chi in the past 12 months. In 2017, the initial question asking about whether sample adults had ever practiced tai chi was not asked. Instead, all sample adults aged 18 and older were asked whether they had practiced tai chi in the past 12 months.
In 2007, sample children were added to the universe for this question. In 2007 and 2017, the person responding for the sample child was asked whether the child had practiced tai chi in the past 12 months. In 2012, the respondent was first asked whether the sample child had ever practiced tai chi and then asked whether the child had practiced tai chi in the past 12 months. In 2007, respondents for sample children under age 18 were asked about tai chi, and in 2012 and 2017 respondents for sample children aged 4 and older were asked about tai chi.
