Description

For sample adults, EXBIKE indicates whether the respondent had engaged in biking in the past 2 weeks.

Data Collection Process 

To obtain this information, interviewers first noted whether the sample adult was physically handicapped.

Interviewers were instructed by the 1995 Field Representative's Manual to

interpret this term ["physically handicapped"] in each individual situation. What may be a physical handicap to one person may not be to another. Obviously, "confined to a wheelchair" or "bedridden" are physical handicaps. Also include conditions that may make it impossible to participate in one or more of the activities listed in question 2. Enter in the "notes" whatever it is about the person that makes you consider him/her to be physically handicapped.

Those sample adults determined by the interviewer to be physical handicapped were asked to list the exercises, sports, or physically active hobbies they had participated in over the past 2 weeks.

Sample adults who were not determined by the interviewer to be physically handicapped were asked about each activity from a list of 22 activities in turn.

Once it was determined whether the respondent had participated in a given physical activity, whether the person had a physical handicap or not, respondents were asked follow-up questions.

For most activities, respondents were asked how many times in the past 2 weeks they had engaged in a particular activity, how many minutes on average they spent doing the activity each time, and what kind of increase (if any) the respondent had to his or her heart rate or breathing while performing the activity. For some activities (e.g., bowling), respondents were only asked how many times they had done the activity in the past 2 weeks.

  • EXBIKENO (Number of times biked, past 2 weeks)
  • EXBIKEMIN (Duration each time biked, past 2 weeks: Minutes)
  • EXBIKEBR (Heart rate/breathing changes when biking)

Comparability

Apart from universe changes, EXBIKE is fully comparable across all years.

  • 1985; 1990: Sample persons aged 18-74 except those who were both judged physically handicapped by interviewer and didn't exercise in the past 2 weeks.
  • 1991; 1998: Sample persons age 18+ except those who were both judged physically handicapped by interviewer and didn't exercise in the past 2 weeks.
  • 1995: Half of sample persons age 18+ (excluded from AIDS supplement) except those judged physically handicapped by interviewer who didn't exercise in the past 2 weeks.
