Insomnia and workplace productivity loss among young working adults: a prospective observational study of clinical sleep disorders in a community cohort.

Objective: To examine associations between three clinically significant sleep disorders (chronic insomnia, obstructive sleep apnoea, restless legs syndrome) and workplace productivity losses among young Australian adults.

Design, Setting: Prospective, observational study; 22-year follow-up of participants in the longitudinal birth cohort Raine Study (Perth, Western Australia).

Participants: Currently employed 22-year-old Raine Study participants who underwent in-laboratory sleep disorder screening for moderate to severe obstructive sleep apnoea (apnoea-hypopnea index of more than fifteen events/hour or obstructive sleep apnoea syndrome) and were assessed for insomnia and restless legs syndrome using validated measures.

Prevalence of common sleep disorders in a middle-aged community sample.

Study Objectives: There is a paucity of contemporary prevalence estimates for common sleep disorders of insomnia, obstructive sleep apnea (OSA), and restless legs syndrome. We aimed to assess the prevalence of clinically significant common sleep disorders in a middle-aged community sample.

Methods: Parents of participants in the community-based Raine Study underwent assessments between 2015 and 2017, including comprehensive questionnaires, anthropometric measures, and in-laboratory polysomnography.
