Description

For sample adults and sample children in 2007 who had taken one or more vitamin supplements during the past 30 days (VITMOSUPNO), VIT1MOST reports the first of two vitamin or mineral supplements that the respondent had taken most often.

Sample adults and respondents for sample children were shown the same list of 20 vitamins and minerals and asked, "Which two of these vitamin supplements did [you/(sample child's name)] take the most in the past 30 days?" Interviewers were given the instruction, "If respondent cannot choose two vitamins/minerals used most often, probe for the two most important for health." See VITMOCALC for the full list of vitamin and mineral supplements shown to sample adults and respondents for sample children.
