Such teenagers, the researchers found, were 50 per centmore likely to engaged in six 'multi-risk behaviours', such as smoking, drunkenness, drug use, having unprotected sex and notusing seat belts, the Daily Mail reported.

The researches also suggested that future studies should examine the specific content adolescents are being exposed to in order to help strengthen current screen time guidelines for youth.
The new findings were published in the Journal of Preventative Medicine.
