A study conducted by Albert Einstein College of Medicine of Yeshiva University in 2012 examined over 11,000 children for more than six years to investigate the relationship between sleep-disordered breathing (SDB) in young children and the development of behavioral difficulties. The research found that children with SDB, including snoring, mouth breathing, and sleep apnea, were more prone to developing behavioral issues such as hyperactivity, aggressiveness, emotional symptoms, and difficulties in peer relationships. The study utilized questionnaires filled out by parents and assessed behavior using various scales. The strongest correlation was observed with hyperactivity, but significant associations were found across all five behavioral measures. The study highlights the importance of recognizing SDB symptoms early and seeking appropriate evaluation and treatment for affected children.
