Sleep loss and daytime sleepiness in the general adult population of Japan
Abstract
There are few epidemiological studies on sleep loss and daytime sleepiness in the general adult population of Japan. A total of 4000 adult people, aged 20 and over, were randomly drawn from five areas of Japan, and 3030 individuals were interviewed and completed a questionnaire including information about sleep duration and sleep problems. Overall, 29% slept less than 6 h at night, 23% reported having insufficient sleep, and 6% took sleep enhancing medications. The prevalence rates were 21% for symptoms of insomnia and 15% for excessive daytime sleepiness. Symptoms of insomnia were more prevalent in the elderly, whereas young people were more likely to report short sleep duration, subjective insufficient sleep and excessive daytime sleepiness. A multiple logistic regression model revealed that excessive daytime sleepiness had significant associations with young people, short sleep duration, insomnia symptoms, subjective insufficient sleep and sleep enhancing medication use. Short sleep duration was the strongest predictor of excessive daytime sleepiness. The findings indicate that sleep loss and excessive daytime sleepiness in the Japanese adult population are common, and comparable to those reported in Western countries. Excessive daytime sleepiness in the general adult population seems more likely to be attributed to short sleep duration.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
