What to know
- Nearly 1 in 4 U.S. adults had a mental illness in the past year, and almost 3 in 10 high school students reported poor mental health.
- Mental health—which includes emotional, psychological, and social well-being—is important for overall health and well-being.
- Mental health conditions (like depression) increase the risk of chronic conditions, which in turn can increase the risk of mental health conditions.
- Public health strategies can address these conditions and promote mental health and emotional well-being.

Summary
In 2021, 29% of high school students experienced poor mental health (most of the time or always) during the past 30 days.1 While mental health affects children and adolescents of all ages, ethnic/racial backgrounds, and regions, the magnitude of health issues vary across subpopulations.1,2 For example, female students were more likely than male students and Asian and Black students were less likely than Hispanic and multiracial students.1 Children and adolescents growing up in poverty are two to three times more likely to develop mental health issues than peers who are not living in poverty.2,3 Although mental health issues in children and adolescents are widespread, they are treatable, and often preventable. In 2021, the Surgeon General issued an advisory that provides actionable recommendations for various audiences and sectors to support the mental health of children and adolescents.1

Summary
Depression is a common and serious mood disorder. It causes severe symptoms that affect how you feel, think, and handle daily activities, such as sleeping, eating, or working.1 In 2019, an estimated 47 million U.S. adults (19%) reported they had been told by a doctor they had a depressive disorder, including depression, major depression, dysthymia, or minor depression in their lifetime.2 In 2019, 7% of all U.S. adults experienced moderate or severe symptoms of depression within the past 2 weeks with women more likely than men and adults ages 18–29 more likely than adults 30 years and older to experience any level of severity of symptoms.3 Depression, even the most severe cases, can be treated. The earlier treatment begins, the more effective it is.1

The question only assesses lifetime, not necessarily current, depression, and does not assess severity or duration of depression.

Summary
Experiencing symptoms of depression in the postpartum period is common1-3 and symptoms often reoccur—over half of women with depression in the postpartum period had a diagnosis either during or preceding pregnancy.3 Postpartum depression has negative effects on maternal health, relationships, and behaviors; infant cognitive and language development and quality of sleep; and on mother-child interactions, including bonding and breastfeeding.4
Notes
This indicator represents self-reported depressive symptoms only and is not equivalent to a diagnosis of depression. Further, it cannot be used to distinguish reoccurring symptoms or new symptoms, only those at time of survey. Various similar tools assessing self-reported depressive symptoms including feelings of being down, depressed, sad, or hopeless, have been recommended for depression case-finding. Sensitivity measures for these tools is generally high with moderate to high specificity measures.5, 6

Summary
In 2021, US adults reported an average of 4.7 recent mentally unhealthy days, defined as the number of days in the past 30 days a respondent experienced poor mental health because of stress, depression, or problems with emotions.1 The average number of mentally unhealthy days was higher for women than men.1 Mentally unhealthy days is one of CDC’s health-related quality of life measures (CDC HRQOL-4).2 As mental health and physical health are closely connected, promoting good mental and physical health through individual- and community-level interventions (e.g., physical activity programs; smoking cessation programs, screening programs) can improve health by preventing and managing chronic disease risk factors and adverse outcomes.3

Summary
In 2021, 14.7% of US adults reported frequent mental distress (FMD), defined as 14 or more mentally unhealthy days during the past 30 days where the person has experienced poor mental health because of stress, depression, or problems with emotions.1 FMD estimates are higher for women than men.1 FMD is also negatively associated with life expectancy and positively associated with behavioral and metabolic risk factors.2 Mentally unhealthy days is one of CDC’s health-related quality of life measures (CDC HRQOL-4). FMD is used to identify individuals with more severe or persistent health problems in the previous month.1 Many chronic diseases can impact general health status, including mental distress. Practicing healthy behaviors (e.g., not smoking, eating healthy, being active, and limiting drinking) can reduce the likelihood of getting a chronic disease and improve the odds of staying well, feeling good, and living longer.3

Summary
Perinatal mental health conditions are often underdiagnosed and under- or untreated.1 Detection or screening is often the first step in the care pathway for mental health conditions,1 including depression.2, 3 Multiple professional and clinical organizations recommend screening for perinatal depression, including the American College of Obstetricians and Gynecologists,4 the American Academy of Pediatrics5, and the United States Preventive Services Task Force.6 The Women’s Preventive Services Initiative, a federally supported collaborative program led by the American College of Obstetricians and Gynecologists (ACOG), recommends screening for anxiety in adolescent and adult women, including those who are pregnant or postpartum.
Notes
Indicates whether a health care provider inquired about depression and anxiety during postpartum visits but does not indicate whether recommended screening and referrals were performed or of the content of any care provided outside of the health care setting. Self-report data on sensitive topics are subject to social desirability bias; challenges with recalling past experiences also may introduce bias. This indicator results from a new question in a new phase of the PRAMS survey, Phase 9. Phase 9 PRAMS data will not be available until 2024 (Phase 9 will begin with 2023 births).
