Abstract OBJECTIVE: To investigate the prevalence of snoring in school age children from Changsha City, and study the correlation of snoring with attention deficit and hyperactivity-impulsivity. METHODS: A total of 1 736 children aged 6 to 12 years were randomly sampled from five districts in Changsha City. Their parents completed the questionnaires about children's sleep conditions and the Attention Deficit Hyperactivity Disorder Diagnostic Scale-Parent Version. RESULTS: The total incidence rate of frequent snoring was 5.7%. Boys had higher incidence of frequent snoring than girls (7.5% vs 3.8%; χ2＝18.782, P<0.01). The incidence of snoring in the 6-to 9-year-old group was higher than that of the 10-to 12-year-old group (χ2=9.666, P＜0.01). The incidence of daytime sleepiness in the snoring group was higher than that in the non-snoring group (31.5% vs 25.9%; χ2=6.678, P<0.01). The incidences of larynx choking, sleep apnea, mouth breathing, hyperhidrosis, and awaking for unknown reasons or awaking by choke in the frequent snoring group were significantly higher than in the occasional snoring and the non-snoring groups (χ2=37.035, 27.745, 51.341, 30.975, 45.972 respectively; all P＜0.01). The incidences of attention deficit (31.3%) and hyperactivity-impulsivity (18.2%) in the frequent snoring group were the highest, followed by the occasional snoring (16.2% and 9.9% respectively) and the non-snoring groups (13.9% and 8.8% respectively). There were significant differences in the incidence of both attention deficit (χ2=20.592, P<0.01) and hyperactivity-impulsivity (χ2=9.067, P<0.05) between groups. CONCLUSIONS: There is a high incidence of snoring in school age children from Changsha City. Snoring is correlated to attention deficit and hyperactivityimpulsivity. It is essential to pay attention to the mental growth and behavioral problems in children with sleep snoring.［Chin J Contemp Pediatr, 2009, 11 (7):562-565］
