Outline of Final Research Achievements

Children with behaviorally induced insufficient syndrome may develop symptoms similar to ADHD such as increased aggression, decreased attention, concentration, motivation, restlessness, coordination failure. This study focused on sleep apnea disorder in particular, and conducted a survey on children who take ADHD - like behavior.
For all elementary school students enrolled in M city in October 2014, responses were obtained from 24,296 children, about 90% response rate. We analyzed the data of the 17,769 children, after deleting incomplete responses etc. The results showed the relationship between short sleep duration and obesity. Moreover, it became clear that short sleeping time and SDB (Sleep-disordered breathing) are related to problem behavior.
