Nearly three out of five high-school girls in the U.S. who were surveyed reported feelings of persistent sadness or hopelessness in 2021, a roughly 60% increase over the past decade, new research from the Centers for Disease Control and Prevention found. The trend accelerated during the Covid lockdowns.

Though both high-school girls and boys reported experiencing mental-health challenges, girls reported record high levels of sexual violence, sadness and suicide risk, the CDC said. In 2021, 57% of high-school girls reported experiencing persistent feelings of sadness or hopelessness in the past year, compared with 36% in 2011. Thirty percent reported they seriously considered attempting suicide in 2021, up from 19% in 2011.
