Description
VITMOCOMBO indicates whether a sample person had taken a multivitamin and/or mineral combination in the past 30 days. In 1987, this information was asked of sample adults who had taken vitamin/mineral supplements (VITANY) and multiple vitamins (VITAMULTV) in the past 12 months. In 2007, this information was collected from both sample adults and sample children who had taken vitamins or minerals in the past 30 days (VITMO). In 2010 and 2015, this question was included as part of the cancer supplement, and was asked of sample adults who reported taking vitamin or mineral supplements during the past month.
Question Wording and Data Collection[show more]
In 1987, sample adults were asked, "Did you take any multiple vitamins in the past month?"
In 2007, responses to VITMOCOMBO by sample adults were obtained as follows: While administering the NHIS, interviewers showed respondents a flash card containing a list of vitamins and minerals and asked, "During the past 12 months, have you taken any vitamins or minerals listed on this card for yourself?" Respondents who answered affirmatively (i.e., a "Yes" response in VITYR) were asked, "During the past 30 days, did you take any of these vitamins or minerals?" Sample adults who answered that question affirmatively (i.e., a "Yes" response in VITMO) were instructed, "Please tell me which of these vitamins or minerals you took in the past 30 days. If you take a multi-vitamin or mineral, include it as one supplement." Interviewers were told to "enter all that apply." The questions to collect this information for sample children were similar, except respondents were asked whether the sample child had taken any vitamins or minerals listed on a card.
In 2010 and 2015, respondents were asked "DURING THE PAST MONTH, did you take any multi-vitamins such as One-A-Day, Theragan, or Centrum?"
