Alternatives to polysomnography for children with suspected obstructive sleep apnoea.

打鼾是阻塞性睡眠呼吸暂停（OSA）的主要症状，是儿童时期的一个主要健康问题，对认知、行为和心血管健康有重大影响。大约35%的儿童打鼾，但其中只有10%患有阻塞性睡眠呼吸暂停综合症。诊断打鼾儿童的阻塞性睡眠呼吸暂停需要多导睡眠图，这是一项技术上具有挑战性且昂贵的测试。在这项研究中，我们将检查一些简单的测试对OSA的预测能力，开发一种工具，使临床医生能够在不需要多导睡眠图的情况下诊断OSA。

Snoring is the cardinal symptom of obstructive sleep apnoea (OSA), a major health issue in childhood with significant impacts on cognition, behaviour and cardiovascular health. Approximately 35% of children snore but only about 10% of those have OSA. Defining OSA in a snoring child requires polysomnography, a technically challenging and expensive test. In this study we will examine a number of simple tests for their predictive power for OSA, developing a tool that will enable clinicians to diagnose OSA without the need for polysomnography.
