London (CNN) Teenage drinking has declined across Europe, with the most dramatic falls in Britain, the World Health Organization (WHO) has found.

Half of all teenage boys in England drank weekly in 2002, but this figure was down to one in 10 by 2014, the report said

For teenage girls, the same number dropped from 43% in 2002 to 9% in 2014, with similar falls reported in Scotland and Wales.

The findings point to significant reductions in adolescent drinking in Britain. Among the 36 European regions included in the survey, England had scored second-worst in 2002 for the measure -- but by 2014 the country was seventh-best.
