Objectives:
Attention Deficit Hyperactivity Disorder (ADHD) and obesity are major pediatric public health problems. The present study aimed to examine the association between these two health parties in our pediatric populations.
Materials & Methods:
This study is a single group retrospective cohort study about Body Mass Index (BMI) changes in 149 children and adolescents between 3-18 years old with a diagnosis of ADHD based on one child and adolescent psychiatrist interview according to the Diagnostic and Statistical Manual of Mental Disorders 4th edition criteria (DSM-IV-TR). All participants were treated with methylphenidate. Besides, they were reassessed by the Kiddie Schedule for Affective Disorders and Schizophrenia-Present and Lifetime Persian version (K-SADS-PL-P). Furthermore, the height, weight, and BMI of participants were calculated. The data were analyzed by descriptive statistics, repeated measures, and Wilks' lambda analysis using IBM SPSS Statistics version 23.
Results:
The mean age of patients was 8.2±2.6 years, and 71.8% were boys. The obtained results showed that those treated with methylphenidate for more extended periods had higher BMI increases (p <0.001). The change in BMI was not related to the age at the start of treatment (p = 0.125), but this index was significantly different based on the years under treatment (p = 0.002). Moreover, changes in BMI were not significant based on gender (p = 0.850), the type of ADHD specifiers (p= 0.686), and concomitant drugs (p = 0.783).
Conclusion:
This study's findings suggest that long-term use of ADHD medications could raise the risk of obesity in children.

Ephedrine and pseudoephedrine lack a catecholamine group, making them less susceptible to degradation by metabolic enzymes. They have increased oral bioavailability and lipophilicity, resulting in a longer duration of action. Their response is reduced by...

Emergency and Intensive Care Unit (ICU) applications: Pressor agents increase blood pressure, heart rate, and contractility in shock and organ failure situations. Dopamine can induce vasodilation and stimulate adrenoceptors. Endogenous catecholamines are effective in treating cardiogenic shock. α2-agonists like clonidine can reverse anesthesia-induced hypertension.

Aromatic ring substitutions: Substituting the aromatic ring with –OH groups at positions 3 and 4 yields catecholamines (e.g., epinephrine), which have a high affinity for adrenoceptors. Hydrogen bonding between –OH groups and receptors enhances adrenergic activity.
