     Within a few years, girls in Europe have become heavier smokers than boys, for reasons that experts

still don't understand, according to a British study presented (递交) last week to an international conference

(大会) on smoking.

     Anti-smoking activists at the second "Tobacco or Health" conference pointed out that although adults

were giving up smoking in growing numbers, more and more young people were taking up the habit,

particularly girls.

     One-fourth of the 15-year-old young people smoke regularly, according to the study made in 27 countries

by Edinburgh University together with the World Health Organization.

     In Western Europe, girls were more likely to smoke than boys. In Germany or in England, one third of

the girls were smokers compared to (相比) one in four boys. In Eastern Europe, the girls "still fall behind"

those in the Western Europe but were "catching up" quickly, said the study.

     The study dealt with the behavior of 15-year-old in seven European countries between 1986 and 1998.

     The percentages (百分比) of young women smoking went from 17% to 36% in Austria, from 17% to

28% in Norway, from 21% to 28% in Hungary.

     In the seven countries and regions studied-Austria, Finland, Hungary, Norway, Sweden, Switzerland and

Wales-more girls smoked than boys, with the exception (例外) of Hungary.
