Title: Predicting brain health outcomes from objectively-assessed sleep duration in UK Biobank
Speakers: Matthew Whelan
Abstract:

Consistently short or long sleep duration, commonly defined as less than 7 hours or more than 9 hours of sleep, respectively, is implicated in worse outcomes for brain health. This includes increased risk of developing neurodegenerative diseases such as dementia, worse performance in cognitive tests, and smaller brain volume. However, most studies on sleep duration use subjectively reported sleep measures, which are known to match poorly with objective measures. This presentation will present findings for an initial associational analysis using data from UK Biobank. It assesses the feasibility of predicting brain health outcomes from sleep duration derived using accelerometery data.
