VITYVITCMG is a variable with five columns and no implied decimal place.
00000 = NIU
99999 = Unknown
For sample adults in 1987 who had taken vitamin or mineral supplements (VITANY) and vitamin C (VITAMINC) in the past 12 months, VITYVITCMG reports the number of milligrams of vitamin C in each pill taken by the respondent (VITYVITCPILS).
Respondents were asked, "How many milligrams of vitamin C are in each of the pills you took?"
The Field Representative's Manual instructed interviewers as follows:
It is possible to use both VITYVITCMG and VITYVITCPILS to determine the number of milligrams of vitamin C respondents were taking, on days they took vitamin C. The related variables VITAMINCMO and VITAMINCDMO report the frequency of respondents' use of vitamin C in number of months and number of days per month, respectively.
Analysts interested in the amount of vitamin C taken may wish to consult the following variables, which report similar information for other vitamins/minerals (all only available for 1987). Users should note that calcium is also measured in milligrams (a measure of quantity), but vitamins A and E are measured in international units (IUs, a measure of biological activity). Further, a direct comparison of IUs across substances is not possible. That is, 1,000 IUs of vitamin A is not equivalent to 1,000 IUs of vitamin E.
