FRIDAY, March 11 (HealthDay News) -- Watching your team win a
major sporting event that ends in a close score can be thrilling,
but there may be a drawback: aggressive, testosterone-fueled
driving by victorious fans.
A new study has found that traffic deaths at the game site and
the hometown of the winning team increase significantly when the
"nail-biter" game is over.
Researchers at North Carolina State University examined traffic
deaths that occurred after 271 professional and college football
and basketball games played between 2001 and 2008. The analysis
included traffic deaths that occurred in the area where the game
was played, as well as in the hometowns of the winning and losing
teams.
As part of the study, a panel of experts was asked to rate how
close a game was on a scale of 1 to 5, with 5 being a nail-biter
and 1 being a blow-out. The investigators found a significant
increase in traffic deaths following close games, and games that
were nail-biters were far more likely to be associated with fatal
accidents than games that were blow-outs.
In fact, each increase in the rating was associated with a 21
percent increase in traffic deaths at the game site. Traffic deaths
were 133 percent higher after a nail-biter than a blow-out, the
researchers explained in a university news release.
But the increase in traffic deaths occurred only in places where
there were winners -- the site of the game and the winning team's
hometown, they noted.
"This pattern of results is important in that it suggests that the cause of the relationship might be associated with competition-induced testosterone," lead author Stacy Wood, a professor of marketing at North Carolina State University, said in the news release.
"During a close game, testosterone increases for the fans as well as the players -- that has been established by previous studies," Wood said. "After the game, testosterone levels drop for the losing side, but spike for the winning side. Because testosterone is linked to aggressive behavior and potentially aggressive driving, we hypothesize that this may play a role in the increased number of traffic fatalities in areas with a high proportion of winning fans."
The study is slated for publication in an upcoming issue of the
Journal of Consumer Research.
