Do adolescents with extreme obesity differ according to previous treatment seeking behavior? The Youth with Extreme obesity Study (YES) cohort.

Adolescent extreme obesity is associated with somatic and psychiatric comorbidity, low quality of life, and social dysfunction. Nevertheless, few adolescents seek obesity treatment, thus many may elope appropriate care. We examine whether previous treatment seeking relates to disease burden, and whether previously non-treatment seeking adolescents accept diagnostic and therapeutic offers. This information is important to inform intervention strategies. The Youth with Extreme obesity Study (YES) is a prospective, multicenter cohort study. We developed a novel recruitment strategy to span medical and vocational ascertainment settings and directly compare previously treatment seeking and non-treatment seeking youth. Participants aged 14-24 years; BMI ≥ 30 kg/m Of 431 participants, 47% were male; mean age 16.6 (standard deviation 2.3) years, BMI 39.2 (7.5) kg/m Irrespective of previous treatment seeking, adolescent extreme obesity was associated with high comorbidity and psychosocial burden. Acceptance of the diagnostic program overall and the therapeutic program at the job center were high. This underscores the need of innovative, accessible programs beyond the currently offered care.
