Snoring in Children Linked to Low Grades

By HospiMedica staff writers
Posted on 02 Sep 2003
A large study of sleep-disordered breathing has shown that habitual snoring in children is associated with poor performance in math, science, and spelling. More...
The findings were reported in the August 15, 2003, issue of The American Journal of Respiratory and Critical Care Medicine.

Researchers amassed information on 1,129 primary students in Germany, of whom 410 (36.3%) never snored, 605 (53.6%) snored occasionally, 89 (7.9%) snored frequently, and 25 (2.2%) always snored. Snoring "always” was significantly associated with low grades in math, science, and spelling; while snoring "frequently” was significantly associated with low grades in math and spelling. The researchers assessed snoring and intermittent hypoxia using a parental questionnaire and nocturnal home oximetry. Children with intermittent hypoxia showed no independent link to poor academic performance, whereas children without intermittent hypoxia did show a significant relationship between snoring and poor grades.

The study was conducted by researchers at the University of Tuebingen (Germany), Hannover Medical School (Germany), and the University of Vienna (Austria). The researchers say this is the first study to show a clear biologic relationship between snoring frequency and the risk of poor academic performance.

Images from patient T1, who had menstrual cycle–dependent right shoulder pain. (A) Maximum-intensity-projection images show abnormal findings for right diaphragm (arrowhead), bilateral round ligaments, peritoneum around bilateral ovaries, and left fallopian tube. Combined PET/MRI show hyperintense lesion with focal uptake inferior of right diaphragm, indicative of endometriosis (arrowhead, B). Confirmatory laparoscopy demonstrated extensive pelvic disease and implants of right diaphragm (C) that stained intensely positive for FAP (D).  (Image Credit: Schindler P, Brandt J, Bobe S, et al.
