Teens are more depressed than feeling depression and self-harm and give less sleep overnight than 10 years.
However, smoking, alcoholism and social antisocial behavior (often with mental health problems) were less than 14 years before 2015 in 2015.
The factors that have detected mental health problems may change, as University College London researchers have said.
The rise of symptoms depression was "profoundly disturbing," Charity said.
London and Liverpool researchers analyzed data from two major 14-year cohorts: the first team around Bristol was born in 1991-92 and the second in the United Kingdom was born in 2000-01.
In the first group, 5,600 young people gathered and 11,000 in the second.
In 10 years, according to the standard questionnaire about humor and feelings, age depression levels ranged from 9% to 15%.
Teenagers with the same goal increased from 12% to 14%. The growth rate was similar to that of boys and girls, even though girls were causing self-harm.
How to change teenage health and behavior 10 years, 2005-15
Study based on two under 14 peers
While obesity and body were weak, less than 14 year olds in 2015 tried to drink alcohol, drink, smoke, and sex compared to those surveyed a decade earlier.
Even less, cannabis or other drugs have been tested by 4.3%, down from 5%.
When he was thirsty, the 2015 cohort was likely to sit down and wake up later, some of which was less than eight hours of sleeping recommended for teens.
Dr. Praveetha Patalay, associate professor at UCL and author of the International Journal of Epidemiology, said research had contributed to a higher image of teens' health, not just isolated mental health.
"It is a holistic point of view, worse and some improvements.
"We have to remember that a lot of things are changing for young people in different directions."
He said, although the study could not determine the causes of mental health problems, the risk factor may be the identification of mental risks.
In the first years, Lauren Nicole Coppin Campbell, now 21 years old, began to undergo corporal image and low self-esteem.
For him, the image of the people who watched the social media and public culture had a negative impact.
"I did not like people who were watching my stream.
"You have seldom seen curvy, chubby, black women or girls portraying themselves as beautiful or intelligent.
"When you see stereotypes in the media or in other media, you feel like a bigger woman comedy, a funny person laughs or feels like you".
At the age of 16, he was sick to achieve what he called "the crush of perfection".
Sometimes it was not like getting away.
"It's not just online", he added.
"You can go to school or see friends at the weekend and start talking about Kylie Jenner or feeling less than others."
Lauren is now working as a plus size model and is The Ambassador of The Be Real Campaign.
Emma Thomas, the executive of the YoungMinds charity, said the 14-year growth of self-harm or depression symptoms was "profoundly alarming."
"Factors with mental health problems are often complex, but we know that stress in school, bullying, body care, and pressures on social media can have a great impact," he said.
"To make things worse, it is very difficult for young people to receive mental health care, which means that their problems are wasted."
Dr. Bernadka Dubicka, Professor of Children and Teenagers at the Royal Psychiatrist's College, said: "This study confirms that young people are having mental health problems with over 90 homosexuals today.
"There is a significant rise in the depression and the worrying increase of one's own health, the concern that our young people have on their body."
