STRETCHFNO is a 3-digit-numeric variable.
000: Not in Universe
994: 994+ times
996: Unable to do this activity
998: Unknown-not ascertained
999: Unknown-don't know
STRETCHFNO reports the frequency, in number of units, with which sample adults engaged in stretching leisure-time physical activities. It must be interpreted in conjunction with the variable STRETCHFTP, which reports the time period (e.g., per day, week, month, or year) corresponding to the number of units in STRETCHFNO. For example, a respondent who does yoga once a day would have a STRETCHFNO value of 1 (to indicate 1 time) and a STRETCHFTP value of 2 (which is the code for "day").
STRETCHFWK, a recoded variable created by the staff at the National Center for Health Statistics, draws upon the information in STRETCHFTP and STRETCHFNO and reports the frequency of stretching leisure-time physical activities in terms of a single time unit, times per week.
Stretching leisure-time physical activities are described in the survey question itself as "physical activities designed to stretch your muscles such as yoga, or exercises like bending side-to-side, toe touches, and leg stretches."
According to the Field Representative's Manuals for 2001 forward, the maximum frequency of each broad category of physical activity was topcoded at 4 times per day (or its equivalent in some other time unit).
For further discussion of data collection on leisure-time physical activity in general for 1997 forward, see VIG10FNO (Frequency of vigorous activity 10+ minutes: Number of units).
