Abstract
Background: Attention-deficit/hyperactivity disorder (ADHD) has been linked to obesity and type 2 diabetes, suggesting heightened cardiovascular risk. Whether adults with ADHD also show increased rates of metabolic syndrome (MetS), a cluster of central obesity, dyslipidemia, impaired glucose regulation, and hypertension, remains unclear. Methods: We examined a young to middle-aged adult cohort of 83 patients and 82 healthy controls (HC). The primary objective was to test whether MetS (Joint Interim Statement criteria) was more prevalent in ADHD than in HC. To explore potential pathways linking ADHD with cardiovascular risk, we additionally assessed anthropometric indices, 24-h blood pressure (BP), heart rate (HR), and inflammatory markers (interleukin-6, C-reactive protein). Finally, we fitted a serial mediation model examining whether hyperactivity/impulsivity (HI), eating behavior, and body mass index (BMI) mediated the association between ADHD and BP. Results: A higher proportion of ADHD patients fulfilled MetS criteria (OR 2.29). Adults with ADHD showed higher waist circumference, BMI, and overweight/obesity rates but did not differ in glucose and blood lipid levels. Non-stimulant medication and psychiatric comorbidity were more common among patients with MetS. Inflammatory markers were unrelated to ADHD. However, ADHD patients demonstrated slightly higher mean 24-h HR and nighttime systolic BP. The association between ADHD and nighttime systolic BP was mediated by obesity as a MetS constituent, and by HI and disordered eating as behavioral risk factors. Conclusion: Young to middle-aged adults with ADHD displayed increased MetS prevalence and subtle elevations in nighttime BP and HR, suggesting an early cardiovascular risk trajectory. Behavioral factors, particularly overeating and weight gain, and psychiatric comorbidity appear to contribute to this risk. These findings support early cardiovascular screening and weight-management interventions in adults with ADHD.
