title: An adolescent age group approach to examining youth risk behaviors.
abstract: OBJECTIVE
  To investigate relationships among youth risk behaviors and demographic factors using an adolescent age group approach.
  
  
  METHODS
  Cross-sectional data from a randomly selected population. Risk behaviors were compared within specific demographic factors and by adolescent age groups.
  
  
  METHODS
  Racially diverse, inner-city neighborhoods in two midwestern cities.
  
  
  METHODS
  Teenagers (n = 1350) and parents (n = 1350) of the teenagers.
  
  
  METHODS
  Truancy; arrested/picked up by police; weapon carrying; fighting; sexual intercourse; tobacco, alcohol, and other drug use; demographic factors; and family structure.
  
  
  RESULTS
  Youth mean age was 15.4 (+/- 1.7) years and 52% were female; racial/ethnic characteristics were 47% White, 22% Black, 19% Hispanic, and 10% Native American. Parents' mean age was 42.2 (+/- 8.4) years and 81% were female. chi 2 analyses indicated numerous significant (p < .05) youth risk behavior differences within the demographic factors and that many of the differences varied by adolescent age group. For example, risk behavior differences within racial/ethnic groups were most profound in the middle and older age groups, whereas risk behavior differences within parent income, education levels, and family structure were most apparent in the younger age groups. Of the demographic factors, family structure was most frequently associated with the risk behaviors.
  
  
  CONCLUSIONS
  The results generally suggest that the relationships among risk behaviors and demographic factors vary within the adolescent age groups included in this study. The results will be useful for developing age-appropriate prevention programs for youth who fit the profile for these risk behaviors. The study protocol also includes specific sampling methods that may be useful for future studies that intend to collect data from difficult-to-reach populations.
