The study spoke to children across 45 countries.
Irish teenagers are among the least satisfied with life compared to their counterparts in 45 countries, according to research from the World Health Organisation.
The study looked at the health, behaviour and wellbeing of 11, 13 and 15-year-olds around Europe and Canada, and found that Irish teens rank highly when it comes to avoiding things like sugary drinks, smoking and drinking alcohol.
But it also found they rank among the top ten internationally for rates of cyberbullying.
The country’s 15-year-olds ranked second from the bottom when it came to life satisfaction in a table of European countries, above only Malta.
And 13-year-olds here reported lower than average satisfaction with life, ranking 35th in the survey. Only 11-year-olds seemed more content, ranking 25th in their age group for life satisfaction.
Sociology lecturer at Waterford Institute of Technology, Jill O’Mahony, believes the issue around social media needs to be dealt with.
''We're seeing a correlation between life satisfaction going down and social media usage going up'', she said.
''I feel the issue hasn't really been dealt with on a government level, and we're seeing the results of that now''.
The Irish component of the study, published on Tuesday, was led by Prof Saoirse Nic Gabhainn in NUI Galway’s Health Promotion Research Centre.
