Duration of vigorous activity 10+ minutes: Minutes


VIG10DMIN is a 3-digit-numeric variable.

000: Not in Universe
997: Unknown-refused
998: Unknown-not ascertained
999: Unknown-don't know


VIG10DMIN is a recoded variable created by the staff at the National Center for Health Statistics that draws upon the information in VIG10DNO (Duration of vigorous activity 10+ minutes: Number of units) and VIG10DTP (Duration of vigorous activity 10+ minutes: Time period) and reports the duration of vigorous leisure-time physical activities in terms of a standardized time unit, minutes. Thus, a respondent who engaged in vigorous exercise for an hour and half would have a VIG10DMIN value of 90 (to represent 90 minutes).

Vigorous activities are described in the survey questionnaire as activities that "cause heavy sweating or large increases in breathing or heart rate." The Field Representative's Manuals for 1997 forward provide examples of vigorous activities, although these examples were not routinely shared with respondents. These examples include fast walking, fast bicycling, jogging, strenuous swimming or sports play, vigorous aerobic dance, and strenuous gardening.

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).


VIG10DMIN is available beginning in quarter 3 of 1997. For data on the duration of respondents' vigorous activity in the first half of 1997, see VIG20DMIN2.

The question wording for VIG10DNO and VIG10DTP, the variables used to create VIG10DMIN, changed slightly in 2004.


For all years from 1997 forward, the survey section on physical activity began with the statement, "The next questions are about physical activities (exercise, sports, physically active hobbies ...) that you may do in your leisure time." Beginning in 2004, the question about duration of vigorous activities reiterated the point that respondents were only to report leisure-time activities. From 1997 through 2003, interviewers asked, "About how long do you do these vigorous activities each time"; for 2004 forward, they asked, "About how long do you do these vigorous leisure-time physical activities each time?" Thus, beginning in 2004, the question wording made explicit what had previously been implicit and had been specified in the introductory statement only.
