Individuals with ADHD have a higher body mass index (BMI) and a higher prevalence of obesity, with the odds ratio increasing with age. Indeed, the pooled prevalence increase by about 70% in adults and 40% in children. Additionally, individuals with ADHD suffer more from eating disorders (OR=3.82*), especially binge eating (OR=4.13).
Several mechanisms have been suggested to account for this association including shared genetic transmission, dysregulation of dopamine, mood lability, psychiatric comorbidities, and low participation in physical activity, impulsivity, inattention, and poor eating habits. It was found that both children and adults with ADHD consume less healthy foods (such as vegetables, fruits, and dairy products) and more unhealthy foods (fatty, sweet and processed foods, such as snacks, candies, “fast food” and “junk food.”)
*OR=3.82 means 3.82 times more likely
