Codes and Frequencies
For sample children age 7 to 17 (in 1991) or 7 to 15 (in 1998) who played any of nine organized sports during the past 12 months (PLAYSPORTYR), PLAYFOOTB indicates whether the child played football. Respondents were handed a card listing nine sports, including football, and asked, "Which ones did [sample child] play?"
The 1991 Field Representative's Manual defines "organized sports" as any sport that has a sponsor, including school-related activities (such as school varsity or junior varsity teams, intramural or club sports, and physical education classes) or sports played through community organizations, Little League, recreation centers, or Scouts, as well as private lessons.
Related dichotomous variables indicate whether the child played eight other organized sports, as follows:
- Baseball or Softball (PLAYBASEB)
- Soccer (PLAYSOCCER)
- Rugby (PLAYRUGBY)
- Field or Ice hockey (PLAYHOCKEY)
- Lacrosse (PLAYLACROS)
- Wrestling (PLAYWREST)
- Boxing (PLAYBOX)
- Karate or Judo (PLAYJUDO)
For sample children who played football during the past 12 months, interviewers asked follow-up questions about the frequency with which the child wore protective headgear (HGFOOTB) and a mouthguard (MGFOOTB) while playing football. Similar follow-up questions gauged the frequency with which children wore protective headgear and mouthguards while playing the eight other organized sports listed above.
These questions were all part of the sample child health questionnaire in 1991. The 1991 Field Representative's Manual notes that the purpose of such questions was to obtain baseline data on child safety for the "Year 2000 Objectives of the Nation," a series of specific and quantifiable 10-year health objectives set forward by the Department of Health and Human Services in 1990.
In 1998, these questions were part of the "Injury Prevention" section of 1998 sample child "Prevention Module Supplement." The 1998 Field Representative's Manual explains the purpose of this line of questioning as follows:
- 1991: Sample persons age 7 to 17 who played any organized sport in the past 12 months.
- 1998: Sample children age 7 to 15 who played any organized sport in the past 12 months.
