  VIT1PJNTPAIN
  Took 1st vitamin supplement to prevent joint pain or stiffness/other joint condition
  For sample adults in 2007 who had taken one or more vitamin supplements during the past 30 days (VITMO) and had taken the first vitamin supplement to prevent (but not to treat) a specific health problem or condition (VIT1PREV), VIT1PJNTPAIN indicates whether the person had used a vitamin supplement to prevent joint pain or stiffness/other joint condition.
  Joint pain or stiffness/other joint condition was one of 87 possible specific conditions that respondents could report preventing with vitamin supplements. The other such conditions are:
  VIT1MOST reports the specific first vitamin supplement (out of 20 possible vitamins) that was taken most often by the respondent. Analysts interested in the prevention of joint pain or stiffness/other joint condition by other vitamin or herbal supplements should see the related variables VIT2PJNTPAIN, HER1PJNTPAIN, and HER2PJNTPAIN. The corresponding variables VIT2MOST, HER1MOST, and HER2MOST indicate which vitamin or herbal supplement was taken.
  Sample adults and sample children were also asked about their use of vitamin supplements to treat (rather than to prevent) health problems or conditions (VIT1TREAT and VIT2TREAT). Researchers interested in the use of vitamin supplements to treat joint pain or stiffness/other joint condition should see VIT1TJNTPAIN and VIT2TJNTPAIN. For more information on the full range of variables related to the use of vitamin supplements, see VITMO.
