First author [reference]Participants (n/age range)Main findings
Keller et al. [18]937 adolescents between 11 and 18 years oldParents of AA reported a significantly higher percentage of internalizing problems and peer relationship problems (p = 0.022 and 0.001, respectively), while the AA self-report was only significant in peer relationship difficulties (p = 0.004).
Felix et al. [19]66,567 students between 12 and 17 years oldAA had a significantly higher prevalence of common mental disorders (anxiety or depression) than those without asthma (p < 0.00001).
Licari et al. [20]40 AA aged 12 to 17 yearsAnxiety rates sustained at 60% within a group of adolescents with severe asthma. Furthermore, depression was only found in adolescents who had both asthma and comorbid anxiety.
Wu et al. [21]162,766 adolescents between 11 and 16 years oldPatients with asthma had a higher risk of panic disorder than those without asthma (aHR: 1.70), a risk that increased in those who started smoking early (aHR: 4.95). Patients who were hospitalized or visited in the emergency department also had a higher risk of panic disorder (aHR: 2.07).
Valero-Moreno et al. [22]450 adolescents between 12 and 16 years oldAA had lower averages on the self-esteem scale than their healthy peers (p ≤ 0.001).
Park et al. [23]57,303 students aged 12 to 18AAs who experienced a significant degree of stress were 9 times more likely to have depression (p < 0.001) than adolescents not exposed to stress.
Chen et al. [24]153,526 adolescents between 11 and 16 years oldThe suicide HR was higher in adolescents with current or previous asthma than in those without asthma (HR = 1.95 and 2.01, respectively).
Azzi et al. [25]604 teenagers between 12 and 18 years oldAA had more somatic complaints (p < 0.001), attention problems (p = 0.032), and behavioral problems (p = 0.025) than those who were not asthmatic.

AA: adolescents with asthma; aHR: adjusted hazard ratio; HR: hazard ratio.
