FRIDAY, Aug. 15, 2003 (HealthDayNews) -- Children who are heavy snorers may suffer learning problems at school, says a study in the August issue of the American Thoracic Society Journal.
A German study found habitual snoring in third graders was associated with poor academic performance on mathematics, science and spelling.
The study of 1,129 students is the first to show a clear biological relationship between frequent snoring in children and increased risk of poor academic performance.
Of the children in the study, 410 never snored, 605 snored occasionally, 89 snored frequently and 25 always snored.
Snoring "always" was significantly associated with low grades in math, science and spelling, while snoring "frequently" was associated with low grades in math and spelling, the study found.
The researchers assessed snoring in the children and intermittent hypoxia (inadequate amounts of oxygen in the blood). They found no association between intermittent hypoxia in children and poor academic performance. But they did find an significant association between snoring and poor academic performance in children without intermittent hypoxia.
