The purpose of this study is to validate the previously-validated Taiwan Chinese version of Sleep-Related Breathing Disorder scale (SRBD scale) in Hong Kong Chinese snoring children. SRBD scale is an instrument used for prediction of obstructive sleep apnea syndrome. (OSA) The Chinese version of SRBD scale were previously translated and validated in Taiwan. The same questionnaire were administered in a group of 102 snoring children (mean age: 10.7 and 65 boys) from a sleep laboratory in Hong Kong before their sleep studies. The SRBD scores were then validated against the results from sleep studies. By using the definition of apnea-hypopnea index larger than 1.5 as OSA, 28 children (27.5%) had polysomnography-confirmed OSA. The sensitivity, specificity, positive likelihood ratio and negative likelihood ratio of the previously validated cut-off of SRBD score > 0.33 for OSA were 0.5, 0.55, 1.12, and 0.90, respectively. The area under ROC curve was only 0.58, indicates suboptimal performance of SRBD score in predicting OSA. In summary, our study concluded that the previously reported Chinese SRBD scale is not accurate in identifying presence of OSA in Hong Kong Chinese snoring children.
本研究旨在验证先前在台湾验证过的睡眠呼吸障碍量表（SRBD 量表）的香港中文版是否适用于香港的打鼾儿童。SRBD 量表是一种用于预测阻塞性睡眠呼吸暂停综合征（OSA）的工具。该量表的中文版先前已在台湾被翻译并验证。在香港的一家睡眠实验室中，对 102 名打鼾儿童（平均年龄为 10.7 岁，其中 65 名为男性）进行了相同问卷的调查，这些儿童在进行睡眠研究之前都填写了问卷。然后，根据睡眠研究的结果对 SRBD 评分进行验证。根据呼吸暂停低通气指数大于 1.5 的定义，将 28 名儿童（27.5%）确定为多导睡眠图确诊的 OSA。先前验证的 SRBD 评分>0.33 用于 OSA 的截断值的灵敏度、特异性、阳性似然比和阴性似然比分别为 0.5、0.55、1.12 和 0.90。ROC 曲线下面积仅为 0.58，表明 SRBD 评分在预测 OSA 方面的表现不佳。综上所述，我们的研究表明，先前报道的中文 SRBD 量表在识别香港中文打鼾儿童中 OSA 的存在方面并不准确。
