Smart phones are the trendiest accessory for teens - but a new survey suggests they also be the most unhealthy. Is there a link between depression in teens and cellphone use?
Between 2010 and 2015, large national surveys found the number of U.S. teens who felt useless and joyless – classic symptoms of depression – had risen a staggering 33 percent. In the same time period, teen suicide attempts increased 23 percent. (1)
Most tragic of all, the number of 13- to 18-year-olds who committed suicide jumped 31 percent.
The new study, published in Clinical Psychological Science, found that the recent increases in teen depression, suicide attempts and suicide appeared in every background – more privileged and less privileged, across all races and in every region of the country.
The current generation of teens includes those born after 1995. The studies showed that this group was much more likely to experience mental health issues than their millennial predecessors.
The only major change in lifestyle found by the researchers was the sudden growth in smartphone use. According to the Pew Research Center, smartphone ownership crossed the 50 percent threshold in late 2012, precisely when teen depression and suicide began to increase. By 2015, an astounding 73 percent of teens had access to a smartphone. (3)
The study not only found that smartphone use and depression increased in tandem, but the amount of time spent online was also linked to mental health issues. Teens who spent five or more hours a day online were 71 percent more likely than those who spent only one hour a day to have at least one suicide risk factor. Suicide risk factors include depression, thinking about suicide, making a suicide plan, or attempting suicide. Overall, suicide risk factors rose significantly after two or more hours a day of time online.
The researchers cited two other recent studies. These studies followed people over time, and both studies found that spending more time on social media led to unhappiness.
