Washington: A new study conducted by researchers at the Child Study Center at NYU Langone Medical Center found that men diagnosed as children with attention-deficit/ hyperactivity disorder (ADHD) were twice as likely to be obese in a 33-year follow-up study compared to men who were not diagnosed with the condition.
"Few studies have focused on long-term outcomes for patients diagnosed with ADHD in childhood. In this study, we wanted to assess the health outcomes of children diagnosed with ADHD, focusing on obesity rates and Body Mass Index," lead author Francisco Xavier Castellanos, MD, Brooke and Daniel Neidich Professor of Child and Adolescent Psychiatry, Child Study Center at NYU Langone said.
"Our results found that even when you control for other factors often associated with increased obesity rates such as socioeconomic status, men diagnosed with ADHD were at a significantly higher risk to suffer from high BMI and obesity as adults," the researchers said.
According to the Centers for Disease Control and Prevention, ADHD is one of the most common neurobehavioral disorders, often diagnosed in childhood and lasting into adulthood.
People with ADHD typically have trouble paying attention, controlling impulsive behaviours and tend to be overly active.
ADHD has an estimated worldwide prevalence of five percent, with men more likely to be diagnosed than women.
The prospective study included 207 white men diagnosed with ADHD at an average age of 8 and a comparison group of 178 men not diagnosed with childhood ADHD, who were matched for race, age, residence and social class. The average age at follow up was 41 years old.
The study was designed to compare Body Mass Index (BMI) and obesity rates in grown men with and without childhood ADHD.
Results showed that, on average, men with childhood ADHD had significantly higher BMI (30.1 vs. 27.6) and obesity rates (41.1 percent vs. 21.6 percent) than men without childhood ADHD.
The study is published online in the journal Pediatrics.
