BACKGROUND
Seasonal variability on obstructive sleep apnea has already been studied by polysomnography in children. Winter and spring season emerged as critical periods. No data are currently available for pulse oximetry performed at home. The aim of our study was to evaluate the effect of seasonality and age on the results of at-home pulse oximetry performed in children referred for suspected OSA.
METHODS
We retrospectively studied 781 children (64.3% Males), aged 4.9 ± 2.5 years. For all patients, we evaluated both pulse oximetry metrics and the McGill Oximetry Score. Variables for seasonal groups were assessed using Kruskal-Wallis test. A logistic regression model was performed to assess the relationship between patients' main characteristics, season period and the likelihood to have an abnormal McGill Oximetry Score.
RESULTS
Patients recorded during winter were significantly younger (p < 0.02), nadir SpO was significantly lower (p < 0.002) and DI significantly higher than during others seasons (p < 0.005). Moreover, patients recorded during winter were nearly 2 times more likely to have an abnormal MOS (aOR 1.949). The logistic regression showed that also younger age (p < 0.0001) was associated with a higher risk to find an abnormal pulse oximetry.
CONCLUSIONS
In our study, the winter season confirms to be a critical period for pulse-oximetry and it should be taken into account by clinicians for a correct interpretation of tests. Our data show that also younger age affects the prevalence of abnormal at-home pulse oximetry in children.
背景
季节性变化对儿童阻塞性睡眠呼吸暂停的影响已通过多导睡眠图进行了研究。冬季和春季是关键时期。目前尚无关于家庭使用脉搏血氧仪进行监测的季节性变化的数据。我们的研究旨在评估季节性和年龄对疑似阻塞性睡眠呼吸暂停患儿家庭使用脉搏血氧仪结果的影响。
方法
我们回顾性研究了 781 名儿童（64.3%为男性），年龄为 4.9±2.5 岁。所有患者均评估了脉搏血氧仪的指标和麦吉尔血氧仪评分。使用 Kruskal-Wallis 检验评估季节性组别的变量。采用逻辑回归模型评估患者主要特征、季节周期与麦吉尔血氧仪评分异常的可能性之间的关系。
结果
冬季记录的患者明显更年轻（p<0.02），最低 SpO2 明显更低（p<0.002），DI 明显更高（p<0.005）。此外，冬季记录的患者发生异常 MOS 的可能性几乎是其他季节的两倍（优势比 1.949）。逻辑回归显示，年龄越小（p<0.0001），脉搏血氧仪异常的风险越高。
结论
在我们的研究中，冬季证实是脉搏血氧仪的一个关键时期，临床医生应考虑这一点以正确解释检测结果。我们的数据表明，年龄较小也会影响儿童家庭使用脉搏血氧仪异常的发生率。
