Predicting sleep disordered breathing in middle-aged Japanese office workers: A simple and effective screening tool

Area of Science:

• Sleep Medicine
• Occupational Health
• Diagnostic Tools

Background:

• Sleep Disordered Breathing (SDB) is underdiagnosed and linked to serious health issues like metabolic syndrome.
• Early SDB detection is vital, particularly in Japanese office workers who may lack apparent symptoms.
• This study addresses the gap in SDB screening within this specific demographic.

Purpose of the Study:

• Investigate the prevalence of SDB among asymptomatic Japanese office workers.
• Develop and validate a simple, effective screening tool for SDB.
• Facilitate integration of SDB screening into routine health check-ups.

Main Methods:

• A cohort of 518 male office workers participated in sleep monitoring and lifestyle questionnaires.
• Participants were split into derivation and validation groups to create and test an SDB prediction score.
• The study assessed lifestyle, comorbidities, and sleep quality alongside objective sleep monitoring.

Main Results:

• Approximately 28.7% of participants were diagnosed with moderate to severe SDB (Respiratory Disturbance Index ≥15).
• The developed SDB prediction model achieved 91.5% sensitivity and 49.4% specificity.
• The model shows strong potential for identifying individuals requiring SDB treatment.

Conclusions:

• A practical screening tool for SDB has been developed for Japanese office workers.
• This tool can significantly improve early SDB detection and intervention rates.
• Incorporating this tool into health examinations offers a proactive approach to managing SDB and its complications.
