SEATTLE, Feb 20, 2009 (UPI via COMTEX) -- Anti-social behavior among girls and
anxiety among both sexes predicted depression in early adolescence, U.S.
researchers found.
University of Washington social scientists tracked first- and second-graders for
seven years and found that surprisingly, early signs of depression were not
predictive of adolescent depression.
"Anti-social behavior has typically been viewed as a big problem among boys, so
it tends to be ignored among girls. Boys with early anti-social behavior
typically go on to show more anti-social behavior while girls may turn inward
with symptoms, morphing into other mental health problems such as depression
eating disorders, anxiety and suicidal behavior during adolescence," lead author
James Mazza said in a statement.
"When all the risk factors were analyzed, anti-social behavior and anxiety were
the most predictive of later depression. It just may be that they are more
prevalent in the early elementary school years than depression."
More than 800 children participated in the study. Eighty-one percent were white
and 54 percent were boys.
The findings are published in the online edition of The Journal of Early
Adolescence.
