The results were taken from 83,724 young people across 1,100 UK primary and secondary schools.
Each pupil was asked more than 100 health-related questions about their school, home and social activities.
Despite the alarming amount that some children claimed to drink, the good news is that most children showed no interest whatsoever in drinking or getting drunk. In fact, compared with previous surveys, the number of children drinking more than 10 units a week is decreasing.
Simon Antrobus, chief executive of drug and alcohol rehabilitation charity ‘Addaction’, said:
“Children who drink at younger ages are the ones who need help most. We also know that children whose parents misuse alcohol are more likely to develop their own problems later in life.”
