For sample adults in 2002 who had used chelation for their own health during the past 12 months (CHEYR) and had used chelation to treat at least one specific health problem or condition (CHETREAT), CHECON3 reports the third of the three most bothersome conditions treated with chelation.

The 2002 NHIS recognized 74 conditions (including an "other" category) that respondents could have treated with chelation. (See CHETREAT for the full list.) To obtain responses to CHECON3, the interviewer first asked, "For what health problems or conditions did you use chelation?" After recording all answers, the interviewer displayed the list of conditions reported by the respondent and asked, "Which three of these are the most bothersome?" These three conditions are reported in CHECON1, CHECON2, and CHECON3.

Respondents were also asked how much chelation had helped the three conditions reported to be most bothersome. The following variables report the degree of help from chelation for each of the three most bothersome conditions: CHECON1HELP, CHECON2HELP, and CHECON3HELP.
