Effects of sleep-disordered breathing on physical traits, school performance, and behavior of Korean elementary school students in the upper grade levels.
ABSTRACT We investigated the physical traits, school performance, and behavior of Korean children with sleep-disordered breathing (SDB).
We recruited 679 students from an elementary school in Seoul, Korea. We used a survey to collect information on the absence or presence of SDB at both the child's preschool age and his or her current age and on the degree of behavioral disturbance. Physical traits and examination scores were also analyzed. We divided the children into 4 groups: non-SDB group, past SDB group, recent SDB group, and continuous SDB group. Comparisons between these four groups were conducted.
Sixty-one students were excluded because of incomplete information. The current body mass index was significantly higher in the past (19.7 +/- 3.6), recent (21.2 +/- 3.6), and continuous SDB groups (20.7 +/- 3.9) than in the non-SDB group (18.8 +/- 3.2), but only for male students (p < 0.001). The examination scores were not different among the four groups, but the behavioral disturbance scores were much higher in the past, recent, and continuous SDB groups than in the non-SDB group for both genders.
Among these Korean elementary school students in the upper grade levels, the presence of current or past SDB appeared to influence the current body mass index in boys and the presence of behavioral disturbances in both genders. However, SDB was not associated with school performance.

ABSTRACT: Children with neurodevelopmental disorders are at increased risk for sleep issues, which affect quality of life, cognitive function, and behavior. To determine the prevalence of sleep problems in children with the common neurodevelopmental disorder neurofibromatosis type 1, a cross-sectional study was performed on 129 affected subjects and 89 unaffected siblings, age 2 to 17 years, using the Sleep Disturbance Scale for Children questionnaire. Children with neurofibromatosis type 1 were significantly more likely to have disturbances in initiating and maintaining sleep, arousal, sleep-wake transition, and hyperhidrosis, but not problems with abnormal sleep breathing, or excessive somnolence. Although the overall sleep scores were higher in children with neurofibromatosis type 1, this was not related to a coexisting attention deficit disorder, cognitive impairment, or stimulant medication use. Collectively, these results demonstrate that children with neurofibromatosis type 1 are more likely to have sleep disturbances, and support the use of appropriate interventions for this at-risk population.Journal of child neurology 09/2013; 28(11).

ABSTRACT: Adenotonsillectomy is an effective treatment for sleep-disordered breathing in children, but its ability to resolve neurocognitive issues, is not clear. To analyze the outcomes of cognitive and behavioral disorders after one year of adenotonsillectomy. We studied the behavioral and cognitive abnormalities in 45 children with obstructive sleep apnea and 30 healthy controls, aged 3 to 13 years. Psychological tests were performed in both groups at baseline and at 12 months. Preoperatively, all cognitive and behavioral disturbances were higher in the study group than in the control group: attention in 46.7% of cases in the study group versus 20% in the control group (P=.016), anxiety 60.9% versus 40.9% (not significant); memory 55.6% versus 36.7% (P=.019), spatial structuring 64.4% versus 36.7% (P=.017), hyperactivity 42.9% versus 12.5% (P=.016), and attention deficit 46.4% versus 8.3% (P=.003). After one year we observed more disturbances in all variables in the study group. However, significant differences remained only in spatial structure (31.3% versus 3.3%, P=.017), and attention deficit (40.5% versus 16.7%, P=.031). The percentages of patients that improved in one year were not significantly different between both groups. Behavioral and cognitive disturbances in children with sleep apnea were partially resolved following adenotonsillectomy. Improvements in the cognitive and behavioral variables did not differ significantly from those the normal evolution of the individual, and were independent of the resolution of respiratory disorders.Anales de Pediatría 10/2013; · 0.72 Impact Factor
