Codes and Frequencies
MOD10D20MIN provides answers to a follow-up question asked of sample adults who participated in light or moderate leisure-time physical activity for at least 10 minutes but who responded "don't know" when asked, "About how long do you do these light or moderate activities each time?" In such cases, interviewers asked the follow-up question, "Each time you do these light or moderate activities, do you do them 20 minutes or more, or less than 20 minutes?" The answers to that follow-up question are supplied in MOD10D20MIN. Answers from respondents who gave a specific duration for their light or moderate leisure-time physical activity appear in MOD10DNO (Duration of moderate activity 10+ minutes: Number of units) and MOD10DTP (Duration of moderate activity 10+ minutes: Time period).
Moderate activities are described in the survey questionnaire as activities that "cause only light sweating or a slight to moderate increase in breathing or heart rate." The Field Representative's Manuals for 1997 forward provide examples of light or moderate leisure-time physical activities, although these examples were not routinely shared with respondents. These examples include leisurely walking or bicycling, slow swimming or dancing, and simple 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).
