Study: Smartphone use spikes anxiety, depression in 25% of youth

Roughly 25% of youths experience depression, anxiety, poor sleep and high stress due to "problematic smartphone use," according to new research published Friday in BMC Psychiatry.

Why it matters: The report says that how young people use smartphones — in ways that mimic behavioral addiction — could be more harmful for mental health than the phones themselves.

What they found: 17 to 19 year olds are the most frequent sufferers of problematic smartphone use, as found by over a dozen studies cited in the report, and those users said that social networking was the most important part of using a smartphone.

  • Loneliness and low self-esteem were also found to be associated with addictive or problematic smartphone use.
  • Both risk-taking and risk avoidant characteristics were associated with poor smartphone use — like low self-control, emotional instability, impulsivity, and perfectionism.

Methodology: The final report used 41 studies out of the 924 it analyzed, which included over 40,000 children and young people — an age range of those with a mean population of no greater than 25. Researchers used studies from 2011 to 2017 and no language restrictions were applied.

Cellphone-related injuries have skyrocketed over the last decade, according to a new study in JAMA Otolaryngology.

By the numbers: Nearly 40% of injuries between January 1998 and December 2017 were among people ages 13 to 29, and many of them were "associated with common activities, such as texting while walking."

After reviewing 153 studies that analyzed eggs' effect on blood cholesterol, a new report by the Physicians Committee for Responsible Medicine says that industry-funded studies downplayed eggs' potentially negative health effects.

What they found: Over 85% of the analyzed studies demonstrated that eggs negatively effect blood cholesterol, the Washington Post reports — whether those studies were funded by the industry or not.

Despite the hype around young Americans' civic activism and record voter turnout in 2018, the voting power of young people is shrinking.

The big picture: On top of young adults being less likely to show up at the polls, the number of people under 25 who are even eligible to vote has fallen, according to a Census data analysis by Brookings Institution's William Frey.
