Diagnoses of ADHD were confirmed by specialists in either neurology or psychiatry. Adolescents requiring regular and continuous treatment with stimulants with no improvement of symptoms under treatment were classified as having severe ADHD; data were available from 2004 to 2019. During 2015 to 2019, the diagnosis of ADHD was defined, and 65 118 (16.76%) of 388 543 adolescents with mild symptoms who required medications only for learning or who used stimulants irregularly were defined as having mild ADHD.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>The prevalence of severe and mild ADHD was 0.3% and 20.1%, respectively. Obesity was more prevalent among adolescents with severe ADHD than among those without ADHD (13.5% vs 7.5%). In the mild ADHD group 12.6% of males and 8.4% of females were diagnosed with obesity compared to 9.7% and 6.4%, respectively, in the non-ADHD group. The adjusted odds of severe ADHD for males and females with obesity were 1.77 (1.56-2.02) and 2.09 (1.63-2.66) times the odds for males and females with low-normal body mass index, respectively, and 1.42 (1.37-1.48) and 1.42 (1.34-1.50) for males and females with mild ADHD, respectively. The elevated risk persisted in several sensitivity analyses.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions<\/jats:title>\n
