Who Is The Treatment-Seeking Young Adult With Severe Obesity: A Comprehensive Characterization With Emphasis On Mental Health

ObjectiveTo characterize treatment-seeking young adults (16-25 years) with severe obesity, particularly mental health problems.Study Design and ParticipantsCross-sectional study of 165 participants (132 women, 33 men) with BMI >= 35 kg/m(2) or >= 30 kg/m(2) with comorbidities, enrolling in a multidisciplinary obesity treatment program.MethodData collection at admission of present and life-time health issues including symptomatology of anxiety, depression (Hospital Anxiety and Depression Scale) and attention-deficit/hyperactivity disorder (Adult ADHD Self-Report scale); self-esteem (Rosenberg Self-Esteem Scale), suicide attempts, health-related quality of life (Short Form-36 Health Survey), psychosocial functioning related to obesity (Obesity-related Problems Scale), cardiorespiratory fitness (Astrand's bicycle ergometer test), somatic and psychiatric comorbidities, cardiometabolic risk factors, and micronutritional status. We used multiple regression analysis to identify variables independently associated with present anxiety and depressive symptomatology.ResultsMean body mass index was 39.2 kg/m(2) (SD = 5.2). We found evidence of poor mental health, including present psychiatric diagnoses (29%), symptomatology of anxiety (47%), depression (27%) and attention-deficit/hyperactivity disorder (37%); low self-esteem (42%), attempted suicide (12%), and low quality of life (physical component score = 46, SD = 11.2; mental component score = 36, SD = 13.9, P<0.001 for difference). Variables independently associated with present anxiety symptomatology (R-2 = 0.33, P<0.001) included low selfesteem (P<0.001) and pain (P = 0.003), whereas present depressive symptomatology (R-2 = 0.38, P<0.001) was independently associated with low self-esteem (P<0.001), low cardiorespiratory fitness (P = 0.009) and obesity-related problems (P = 0.018). The prevalence of type 2 diabetes was 3%, and hypertension 2%. Insulin resistance was present in 82%, lipid abnormality in 62%, and poor cardiorespiratory fitness in 92%. Forty-eight percent had at least one micronutritional deficiency, vitamin D being the most common (35%).ConclusionA wide range of health issues, including quite severe mental health problems, was prevalent in treatment-seeking young adults with severe obesity. These are likely to constitute a major treatment challenge, including options relating to bariatric surgery.
