Mild sleep-disordered breathing among children fluctuates according to the seasons, research has found.
A US study found that mild sleep-disordered breathing among primary school-age children rose steadily through the summer from 21.6 per cent in June to a peak in September of 37.2 per cent. It then fell again through the autumn to a low of 6.3 per cent in November.
The study involved a random sample of 687 children of primary school age. The findings were published in a supplement of the journal Sleep and were presented last week at a US Associated Professional Sleep Societies conference in Texas.
