Suicide, poison and phones

The Washington Post has an article noting the increase in girls trying suicide by poison (boys prefer guns and strangulation), but it then talks more broadly about the rise in youth suicide and the search for a plausible causes.   Some think the rise of the mobile phone is more than a coincidence:

Spiller said he and others have overlaid their findings with other data to try to identify why the rates have spiked so sharply since 2011. They studied data from the rise of opioid addiction and deaths in recent years, thinking that the sharp increase could be due to increased access to drugs or fallout from parents’ deaths or addictions. But the timing did not fit precisely — the beginnings of the opioid epidemic traces back years before the 2011 spike.

They also compared it against economic data, but much of the country’s downturn occurred in 2008 or 2009.

“Unfortunately, we can’t definitely answer the why. That’s not how the data works,” said John Ackerman, a co-author and clinical psychologist at Nationwide Children’s Hospital in Columbus, Ohio.

Ackerman and Spiller, however, suspect the sudden increase in recent years has to do with the advent of smartphones and how they have made social media much more pervasive in young people’s lives.

The iPhone 3 came out in 2008, Spiller notes, and the Android phones had come into widespread use by 2011. Adults adopted such devices first, but within a year or two, such smartphones became more common among adolescents.

For years now, across all demographic groups, the death rate from suicide has been rising broadly. Experts cannot easily explain it. There is no single factor driving the phenomenon.
