The charity said its findings reveal a 'deeply worrying picture around wellbeing and happiness' among teenagers, adding: 'Alarm bells are ringing.'
A quarter of British 15-year-olds report having poor life satisfaction, the highest rate amongst 27 European countries polled and almost 20 percentage points higher than in Holland.
Among UK teenage girls, almost a third report low life satisfaction, compared to one in five across Europe, the charity found.
British girls aged ten to 15 are 'significantly less happy' with their life, appearance, family and their school than the average boy, with life satisfaction scores declining in girls but stable among boys.
The Children's Society said it is 'particularly troubling' that the gap between boys and girls is widening. Between 2015 and 2022 happiness levels among 15-year-old girls in the UK have also declined more sharply than the European average.
Data from the Good Childhood Report found that 22.6 per cent of girls reported being unhappy with their appearance in 2021/22, compared to 9.2 per cent of boys.
One teenager said their peers often feel they need to 'change' themselves to be accepted, because people won't 'acknowledge you or look at you' otherwise. They said people had to 'look a certain way to be accepted'.
The report said that the dissatisfaction relates to a range of factors including food deprivation, NHS waiting lists for mental health services, bullying in schools and levels of physical activity – with the UK having the fifth highest rate of pupils reporting no physical exercise.
It also found that the 'endemic' level of school absence in some age groups has a 'dramatic' effect on attainment and resulting life satisfaction.
