VITYCALCMG
Took calcium, past 12 months: Number of milligrams per pill

Description

For sample adults in 1987 who had taken vitamin or mineral supplements (VITANY) and calcium (VITACALC) in the past 12 months, VITYCALCMG reports the number of milligrams of calcium in each pill taken by the respondent (VITYCALCPILS).

Data Collection

Respondents were asked, "How many milligrams of calcium are in each of the pills you took?"

 

The Field Representative's Manual instructed interviewers as follows:

Follow the procedure given for units in 3e when completing questions about milligrams. That is, just record the quantity, for example, record "Vitamin C 50.0 mg.-83 USRDA" as "50" on the milligram line. Take only whole numbers, drop decimals.

Related Variables 

It is possible to use both VITYCALCMG and VITYCALCPILS to determine the number of milligrams of calcium respondents were taking, on days they took calcium. The related variables VITACALCMO and VITACALCDMO report the frequency of respondents' use of calcium in number of months and number of days per month, respectively.

Analysts interested in the amount of calcium 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 vitamin C 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.

For more information on the full range of variables related to vitamins and minerals, see VITANY.

Comparability

VITYCALCMG is only available for 1987.
