Don't be so quick to pass along that sage advice to your children about "setting a good example" for a younger brother or sister. New research on birth order suggests that just having an older sibling can be a negative influence on younger children in the family.

The new research by economics professors seeks to understand how teens get involved in risky behaviors that can have long-term economic consequences. It finds that the very existence of an older sibling increases the chances a younger sibling will drink, smoke, use marijuana or have sex.

The published study [ed. note: See, Argys, Laura M.: "Birth Order and Risky Adolescent Behavior", in this bibliography] analyzed data from the National Longitudinal Survey of Youth from 1997 to 1999. It included 7,000 to 8,000 children ages 12 to 16. A second study reviewed data from 1994 to 1996 from the National Longitudinal Survey of Adolescent Health, which includes about 20,000 young people in grades seven to 12. Averett says the second study confirmed the results of the first.
