The report, published by the Varkey Foundation, an education charity, is based on a poll of more than 20,000 people from 20 countries, born between 1995 and 2001.
It places the UK 19th out of 20 nations for mental well-being, with a score of 47.3. Only Japan scored lower, with Indonesia topping the table, followed by India, then Nigeria, Israel and China.
The score is based on young people's views on 14 different areas, such as optimism about the future, feeling loved and good about themselves, feeling confident and cheerful.
Just one in six (15 per cent) of the UK youngsters who took part said they have good physical well-being, meaning that they get enough sleep, regular exercise and time for rest and reflection.
This is the same proportion as number of other countries, including Australia. Nigeria scored the highest for this measure at 41 per cent, followed by India at 24 per cent.
The report reveals that generally, more than two thirds of young people in the UK (67 per cent), think that the country is a good place to live – higher than nations including France (51 per cent), Israel (60 per cent) and the United States (63 per cent).

Stress – Feeling under mental or emotional pressure can lead to sleeping problems, a loss of appetite or difficulty concentrating
Around 46 per cent of the UK youngsters questioned said they have this view because the UK is "a free country where I have the freedom to live the way I want to".
Young people were also asked for their views about global issues such as immigration, and reveals that in the UK, youngsters are split on the matter.
While 31 per cent said it should be made easier for immigrants to live and work legally in the UK, 26 per cent said the Government should make it more difficult.
In comparison, 38 per cent of those in Italy and 37 per cent of those in Germany think that legal migration should be easier, along with 27 per cent of those in France.
Young people in the UK feel the Government is not doing enough to tackle the global refugee crisis
In addition many UK youngsters do not think that the Government is doing enough to combat the global refugee crisis (48 per cent), while 10 per cent think too much is being done.
Extremism and the rise of global terrorism make UK young people more fearful for the future than other issues – this was the top concern for 13 countries.
The findings also show that in general, young people worldwide support values such as tolerance and equality.
An overwhelming nine in 10 (89 per cent) say that men and women should be treated equally, while just under two thirds (63 per cent) think that same-sex couples should be allowed to marry, and three quarters (74 per cent) think that transgender people should have the same rights as other people.

Varkey Foundation chief executive Vikas Pota, said: "At a time of nationalist and populist movements that focus on the differences between people, the evidence shows that young people – whatever their nationality or religion – share a strikingly similar view of the world.
"Teenagers in Nigeria, New Delhi and New York share many of same priorities, fears, ambitions and opinions. There is far more unity among young people than a glance at the headlines would suggest."
