life outcomes in young people, with up to 1 in 5 children ages 3 to 17 in the US with a reported mental, emotional, developmental, or behavioral disorder.17 In 2016, of the 7.7 million children with treatable mental health disorder, about half did not receive adequate treatment.18 Unfortunately, in recent years, national surveys of youth have shown major increases in certain mental health symptoms, including depressive symptoms and suicidal ideation. From 2009 to 2019, the proportion of high school students reporting persistent feelings of sadness or hopelessness increased by 40%; the share seriously considering attempting suicide increased by 36%; and the share creating a suicide plan increased by 44%.19 Between 2011 and 2015, youth psychiatric visits to emergency departments for depression, anxiety, and behavioral challenges increased by 28%.20 Between 2007 and 2018, suicide rates among youth ages 10-24 in the US increased by 57%.21 Early estimates from the National Center for Health Statistics suggest there were tragically more than 6,600 deaths by suicide among the 10-24 age group in 2020.22 Scientists have proposed various hypotheses to explain these trends. While some believe that the trends in reporting of mental health challenges are partly due to young people becoming more willing to openly discuss mental health concerns,23 other researchers point to the growing use of digital media,24, 25, 26 increasing academic pressure,27, 28, 29 limited access to mental health care,18, 30 health risk behaviors such as alcohol and drug use,31 and broader stressors such as the 2008 financial crisis, rising income inequality, racism, gun violence, and climate change.32, 33, 34, 35 It’s also important to acknowledge that the prevalence of mental health challenges varies across subpopulations. For instance, girls are much more likely to be diagnosed with anxiety, depression, or an eating disorder, while boys are more likely to die by suicide or be diagnosed with a behavior disorder, such as attention deficit hyperactivity disorder (ADHD).36, 37, 38 In recent years, suicide rates among Black children (below age 13) have been increasing rapidly, with Black children nearly twice as likely to die by suicide than White children.39 Moreover, socioeconomically disadvantaged children and adolescents— for instance, those growing up in poverty—are two to three times more likely to develop mental health conditions than peers with higher socioeconomic status.40 Protecting Youth Mental Health: The U.S. Surgeon General’s Advisory 9 The COVID-19 Pandemic’s Impact on the Mental Health of Children and Youth During the pandemic, children, adolescents, and young adults have faced unprecedented challenges. The COVID-19 pandemic has dramatically changed their world, including how they attend school, interact with friends, and receive health care. They missed first days of school, months or even years of in-person schooling, graduation ceremonies, sports competitions, playdates, and time with relatives. They and their family may have lost access to mental health care, social services, income, food, or housing.41 They may have had COVID-19 themselves, suffered from long COVID symptoms, or lost a loved one to the disease—it’s estimated that as of June 2021, more than 140,000 children in the US had lost a parent or grandparent caregiver to COVID-19.42 Since the pandemic began, rates of psychological distress among young people, including symptoms of anxiety, depression, and other mental health disorders, have increased. Recent research covering 80,000 youth globally found that depressive and anxiety symptoms doubled during the pandemic, with 25% of youth experiencing depressive symptoms and 20% experiencing anxiety symptoms.43 Negative emotions or behaviors such as impulsivity and irritability—associated with conditions such as ADHD— appear to have moderately increased.44 Early clinical data are also concerning: In early 2021, emergency department visits in the United States for suspected suicide attempts were 51% higher for adolescent girls and 4% higher for adolescent boys compared to the same time period in early 2019.45 Moreover, pandemic-related measures reduced in-person interactions among children, friends, social supports, and professionals such as teachers, school counselors, pediatricians, and child welfare workers. This made it harder to recognize signs of child abuse, mental health concerns, and other challenges.46 During the pandemic, young people also experienced other challenges that may have affected their mental and emotional wellbeing: the national reckoning over the deaths of Black Americans at the hands of police officers, including the murder of George Floyd; COVID-related violence against Asian Americans; gun violence; an increasingly polarized political dialogue; growing concerns about climate change; and emotionally-charged misinformation.47, 48, 49, 50, 51 Although the pandemic’s long-term impact on children and young people is not fully understood, there is some cause for optimism. According to more than 50 years of research, increases in distress symptoms are common during disasters, but most people cope well and do not go on to develop mental health disorders.52 Several measures of distress that increased early in the pandemic appear to have returned to pre-pandemic
