According to Centers for Disease Control and Prevention (CDC) data released this year, nearly 3 in 5 (57%) U.S. teen girls felt persistently sad or hopeless in 2021—double that of boys, representing a nearly 60% increase and the highest level reported over the past decade.

While all teens reported increasing mental health challenges, experiences of violence, and suicidal thoughts and behaviors, girls fared worse than boys across nearly all measures. The new report also confirms ongoing and extreme distress among teens who identify as lesbian, gay, bisexual or questioning (LGBQ+).

“High school should be a time for trailblazing, not trauma. These data show our kids need far more support to cope, hope and thrive,” Debra Houry, M.D., M.P.H., CDC’s chief medical officer and deputy director for program and science. “Proven school prevention programs can offer teens a vital lifeline in these growing waves of trauma.”

The analysis includes 2021 data and trends from the Youth Risk Behavior Survey (YRBS), which examines health behaviors and experiences among U.S. high school students. Youth mental health has continued to worsen—with particularly stark increases in widespread reports of harmful experiences among teen girls:

• Nearly 1 in 3 (30%) seriously considered attempting suicide—up nearly 60% from a decade ago.
• 1 in 5 (18%) experienced sexual violence in the past year—up 20% since 2017, when CDC started monitoring this measure.
• More than 1 in 10 (14%) had ever been forced to have sex—up 27% since 2019 and the first increase since CDC began monitoring this measure.

The report also found more than half (52%) of LGBQ+ students had recently experienced poor mental health and, concerningly, that more than 1 in 5 (22%) attempted suicide in the past year. Trend data are not available for students who identify as LGBQ+ due to changes in survey methods.

Findings by race and ethnicity also show high and worsening levels of persistent sadness or hopelessness across all racial and ethnic groups, and that reported suicide attempts increased among Black youth and White youth.

“Young people are experiencing a level of distress that calls on us to act with urgency and compassion,” said CDC Division of Adolescent and School Health Director Kathleen Ethier, Ph.D. “With the right programs and services in place, schools have the unique ability to help our youth flourish.”

School-based activities can make a profound difference in the lives of teens with a relatively small infusion of support to schools. More than 95% of U.S. youth spend much of their daily lives in school. While their primary goal is academic learning, schools can take evidence-based steps to foster the knowledge, skills and support needed to help prevent and reduce the negative impact of violence and other trauma and improve mental health. For example, safe and trusted adults—like mentors, trained teachers and staff—can help foster school connectedness, so that teens know the people around them care about them, their well-being and their success. Schools can provide education that equips teens with essential skills, such as understanding and ensuring true sexual consent, managing emotions and asking for what they need. Schools  also can connect teens to their classmates and communities through school-based clubs and community outreach.
