Additionally, there are 57 other conditions sample adults only could report treating with vitamin supplements, and 29 other conditions that could be reported for sample children only. For the full list of conditions, see VIT1TREAT.

Persons taking more than one vitamin supplement during the past 30 days were also asked whether their second vitamin supplement was used to treat a specific problem or condition (VIT2TREAT) and, if so, what was that condition. Similarly, persons taking herbal supplements during the past 30 days (HERMO) were asked whether those herbal supplements were used to treat a specific condition (see HER1TREAT and HER2TREAT).

VIT1MOST reports the specific first vitamin supplement (out of 20 possible vitamins) that was taken most often by the respondent. Analysts interested in the treatment of hay fever by other vitamin or herbal supplements should see the related variables VIT2THAY, HER1THAY, and HER2THAY. The corresponding variables VIT2MOST, HER1MOST, and HER2MOST indicate which vitamin or herbal supplement was taken.

Sample adults, but not sample children, were also asked about their use of vitamin supplements to prevent (rather than to treat) health problems or conditions (VIT1PREV and VIT2PREV). Researchers interested in the use of vitamin supplements to prevent hay fever should see VIT1PHAY and VIT2PHAY. For more information on the full range of variables related to the use of vitamin supplements, see VITMO.
