Claim: Teens today are more likely to say they feel persistently sad or hopeless and think about suicide.
In the CNN article cited here, it also mentions particularly girls.
According to the CDC, in 2021, 42% of U.S. high school students experienced persistent sadness and hopelessness. Almost a third experienced poor mental health in the past month, and 10% attempted suicide in the last year.
Furthermore: in 2021, nearly three and five teenage girls reported depressive symptoms. Three in ten seriously considered attempting suicide, and more than one in 10 girls attempted suicide.
The claim was made in a CNN article, which is a mainstream news source. I fact-checked their findings using the CDC. The data cited from the CDC was taken from the findings from the Youth Risk Behavior Surveillance System (a survey). The CDC is a credible public health source that got its findings from U.S. high school students nationwide.
It's clear that there is an overall trend of declining mental health amongst teens, specifically females. According to these sources, it seems to be due to multiple causes. Some theories are because of the earlier onset of puberty or the overuse of social media.
The verdict is true. CNN accurately reported the CDC's findings of teens today saying they feel persistent sadness and hopelessness, and increased thoughts about suicide.
