Introduction

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental condition characterized by symptoms of inattention, hyperactivity, and impulsivity, which only rarely remits in adulthood[1]. A positive association between ADHD and obesity has been repeatedly observed, especially in adult samples[2]. However, only a few studies investigated the prevalence and correlates of ADHD in obese patients seeking bariatric treatment[3,4].

Objectives

Our study was aimed to examine the prevalence of probable ADHD comorbidity in a sample of obese patients referred for bariatric surgery. Secondly, we sought to characterize differences in eating behaviour between obese subjects with and without probable ADHD.

Methods

The study sample was composed of 110 adult obese patients (BMI ≥ 30 kg/m2) consecutively referred for bariatric surgery to the Obesity Center of the Endocrinology Unit in Pisa University Hospital between November 2010 and May 2012. Probable ADHD was identified using a recently developed screening scale based on items selected from Symptom Check‐List‐90‐R (SCL-90-R)[5]. The extent of binge-eating/purging and night-eating behaviours were respectively estimated using the Bulimic Investigatory Test, Edinburgh (BITE)[6] and the Night-eating Questionnaire (NEQ)[7]. Wilcoxon test was used for statistical comparisons, with a significance level of p<0.05 set for all tests.

Results

Probable ADHD was found in 14 subjects (12.7%, 95%CI=7.1-20.4%). Patients with probable ADHD showed significantly higher BITE symptom score (20.4±9.3 vs. 12.1±7.5, r=0.31, p=0.001) and NEQ total score (16.1±9.2 vs. 9.5±3.9, r=0.27, p=0.005).

Conclusions

ADHD is a relatively common comorbidity in obese patients seeking bariatric treatment, which is positively associated with disordered eating habits, such as binge-eating/purging and night-eating behaviours.
