Abstract
Background Data on the validity of tools for sleep apnea risk detection in rotating shift workers are limited. The aim was
to evaluate the Berlin questionnaire (BQ) and the Neck, Obesity, Snoring, Age, Sex (NoSAS) score for the detection of
obstructive sleep apnea risk in shift workers.
Methods This cross-sectional study included male rotating shift workers, drivers of heavy of-road machinery in an iron ore
extraction company. Polysomnography was the gold standard for evaluation. Obstructive sleep apnea (OSA) was defned
as an apnea–hypopnea index (AHI) of≥5 events/h. The Shapiro–Wilk test verifed the data distribution and comparative
analysis was conducted using the chi-square analyses and U Mann–Whitney with Bonferroni correction. Receiver operating
characteristic curve analysis, sensitivity, specifcity, positive and negative predictive values, positive and negative likelihood
ratios, and accuracy were used for evaluate BQ and NoSAS with OSA diagnosis by polysomnograph.
Results Among 119 male shift workers, ages 24 to 57 years, polysomnography showed that 84% had obstructive sleep apnea
(AHI≥5), and 46% had moderate to severe sleep apnea (AHI≥15). For AHI≥5, the NoSAS score had higher sensitivity
and specifcity than the BQ. For AHI≥15 and AHI≥30, the NoSAS score had a sensitivity higher than 70% while BQ was
60% and 58%, respectively. The accuracy of the NoSAS score was higher for all OSA criteria than that of BQ.
Conclusion In rotating shift workers, drivers of heavy of-road machinery, the NoSAS score showed higher accuracy in
identifying patients at risk for sleep apnea than the BQ.
