Sleep habits and excessive daytime sleepiness correlate with injury risks in the general population in Taiwan.
OBJECTIVE
To explore the relationship between sleeping habits, excessive daytime sleepiness (EDS), and different injury risks in the general population of Taiwan.


METHODS
Cross-sectional national data from the Taiwan Social Trend Survey conducted in 2005 by interviews using validated inventories.


METHODS
Population-based face-to-face interviews at participants' residences.


METHODS
36,473 Taiwanese citizens aged 15 years or older.


METHODS
Self-reported EDS was measured using the Epworth sleepiness scale. Other sleep-related problems investigated included self-reported sleep quality (assessed by the insomnia self-assessment inventory) and self-reported inadequate sleep duration (<7 h).


METHODS
Self-reported major injuries that required medical attention.


RESULTS
Considering all sleep-related problems together, multivariate logistic regression analyses showed that EDS and poor sleep quality were significant predictors of higher risks of various injuries. EDS predicted major traffic injuries (odds ratio (OR) 1.62, 95% CI 1.29 to 2.02) and major fall injuries (OR 1.49, 95% CI1.20 to 1.84). Those with poor sleep quality tended to have traffic injuries (OR 1.67, 95% CI 1.41 to 1.99) and major fall injuries (OR 1.73, 95% CI 1.44 to 2.07).


CONCLUSIONS
EDS and sleep quality are associated with the occurrence of a variety of injuries in Taiwan's general population.
