Adolescent Depression

Depression has a significant impact on adolescent development and well-being.122 Adolescent depression can adversely affect school and work performance, impair peer and family relationships, and exacerbate the severity of other health conditions such as asthma and obesity.123, 124, 125 Depressive episodes often persist, recur, or continue into adulthood.126 Youth who have had a major depressive episode (MDE) in the past year are at greater risk for suicide and are more likely than other youth to initiate alcohol and other drug use, experience concurrent substance use disorders, and smoke daily.127, 128, 129

NOTE: Treatment is defined as seeing or talking to a medical doctor or other professional and/or using prescription medication in the past year for depression. Respondents with unknown treatment data were excluded. There is a break between 2019 and 2020 to indicate caution should be used when comparing estimates between 2020 and prior years because of methodological changes for 2020.
