| Sumario: | Given the substantial increase in pediatric obesity rates in recent decades, its long-term stability, and its pervasive negative outcomes, continuous efforts to identify factors that may place children at increased risk for overweight or obesity (OW/OB) are essential. As such, the primary aim of the present investigation was to examine the extent to which symptoms of Cognitive Disengagement Syndrome (CDS; i.e., Sluggish Cognitive Tempo) relates to child body mass index (BMI) independent of Attention-Deficit/Hyperactivity Disorder (ADHD). The study is the first to examine whether CDS subdomains of slowed thinking, hypoarousal, and daydreamy is associated with BMI. Analyses included data from 72 clinically-referred children (46 males, 26 females) aged 4–12 years old (M = 8.41, SD = 2.48). CDS and ADHD were assessed using standardized parent-report rating scales, and children's BMI was collected at the time of encounter. Bayesian hierarchical regression models revealed no evidence that overall CDS symptoms or ADHD symptoms (overall and subdomain) predicted child BMI. However, models did provide moderate evidence that hypoarousal and daydream subdomains jointly predicted BMI independent of ADHD (BF = 19.28–21.87). The present study suggests that CDS is a risk factor for obesity in young children and future research is needed to inform clinical interventions and to provide further understanding of the relatively nuanced association between CDS symptoms and obesity.
