VITAMINCTP
Frequency took vitamin C, past 12 months: Time period

Description

For sample adults in 2000 who had taken any vitamin C during at least 1 month of the past 12 months (VITAMINCMO), VITAMINCTP reports the the time period ("days per week," "days per month," or "other") respondents used to report how frequently they had taken vitamin C during the relevant months.

Interviewers elicited these responses by asking, "During [the/those] month(s), about how many [days [per week]/days per month] did you take vitamin C?" VITAMINCTP must be interpreted in conjunction with VITAMINCNO, which reports respondents' answers to the question in terms of number of days.

Related Variables 

The National Center for Health Statistics recoded data from VITAMINCNO and VITAMINCTP to create two new variables with consistent time units: Number of days per week took vitamin C during the relevant months of the past 12 months (VITAMINCDWK), and number of days per month took vitamin C during the relevant months of the past 12 months (VITAMINCDMO). VITAMINCDMO is also available for 1992, when it was asked as a direct question.

Variables similar to VITAMINCTP are available for the following vitamin/mineral supplements (with years indicating availability):
