[Frequency of overweight and obesity in children and adolescents with autism and attention deficit/hyperactivity disorder].

Objective:: To assess the frequency of overweight and obesity in children and adolescents with autism spectrum disorder (ASD) and with attention deficit/hyperactivity disorder (ADHD) and their parents, in comparison with children and adolescents without developmental disorders.

Methods:: Anthropometric measures were obtained in 69 outpatients with ASD (8.4±4.2 years old), 23 with ADHD (8.5±2.4) and 19 controls without developmental disorders (8.6±2.9) between August and November 2014. Parents of patients with ASD and ADHD also had their anthropometric parameters taken. Overweight was defined as a percentile ≥85; obesity as a percentile ≥95; and underweight as a percentile ≤5. For adults, overweight was defined as a BMI between 25 and 30kg/m and obesity as a BMI higher than 30kg/m.

Results:: Children and adolescents with ASD and ADHD had higher BMI percentile (<0.01) and -score (<0.01) than controls, and increased frequency of overweight and obesity (=0.04). Patients with ASD and ADHD did not differ between them in these variables, nor regarding abdominal circumference. Parents of children with ASD and ADHD did not differ between themselves.

Conclusions:: Children and adolescents with ASD and ADHD are at a higher risk of overweight and obesity than children without developmental problems in the community.
