A study published in Feb 2019 from Gaziantep University in Turkey, examined the obesity/hypertension prevalence of children with ADHD as well as associated risk factors. They found that obesity was present in 16.9% of children, and hypertension was prevalent in 13% of ADHD patients. They also examined sleep and found in girls sleep duration on weekends was shorter in patients compared to controls. Paternal body mass index was also higher in the ADHD group. Screen time >1 hour a day was also more common in ADHD patients. They concluded that the high obesity and hypertension rates emphasizes that the assessment of weight/BP should be a part of ADHD management.
