According to the study, injuries related to serious violence decreased by 12 per cent in 2013 compared to 2012 and the credit for this can be attributed to fall in binge drinking and the rising price of alcohol.
Lead author of the study and director of the research group professor Jonathan Shepherd said, "Binge drinking has become less frequent, and the proportion of youth who don't drink alcohol at all has risen sharply. Also, after decades in which alcohol has become more affordable, since 2008 it has become less affordable."
He added, "For people most prone to involvement in violence, those aged 18-30, falls in disposable income are probably an important factor."
The study also said that the present generation of teenagers show lack of interest in using drugs or smoking. And over the past decade, the percentage which has tried an illicit drug has declined from 27 per cent to 17 per cent.
This is the fifth consecutive year that NHS has reported a decline in violent injuries. Previous NHS figures have suggested that today's young teenagers are much healthier than previous generations.
Only 12 per cent of 11-15-year-olds said they had consumed alcohol in the previous week in 2011, which was 26 per cent a decade earlier.
Similar habits were noticed among older teenagers and young adults. Of 16-26-year-olds, 48 per cent said they had had an alcoholic drink in the previous week in 2010, compared with 71 per cent in 1998.
