     School failure appears to trouble teenage girls more deeply than boys, US researchers said on Tuesday.

     They said adolescent (青春期的) girls who are dismissed or drop out of high school before they graduate

are more likely to have a serious depression by age 21 than boy with similar experiences.

     "For girls it is more serious to be school failure," said Carolyn McCarty, a University of Washington

researcher whose study appears in the Journal of Adolescent Health.

     "We already know that it leads to more poverty, higher rates of being on public assistance and lower rates

of job stability. And now this study shows it is having mental health implications for girls," McCarty said in a

statement.

     The study was drawn from data on more than 800 people in Seattle, Washington,and included people from

18 school in high-crime neighborhoods.

     The group was separated evenly by gender (性别) and nearly half were white, 24 percent were black, 21

percent were Asian-American and the rest were from other groups.

     Overall, 45 percent of the girls and 68 percent of the boys in the study experienced a major school failure,

but 22 percent of the girls later became depressed compared with 17 percent for the boys.

     "This gender shows that while school failure is more typical for girls, it appears to have more severe

consequences when it does occur," McCarty said.
