Doctors commonly view excessive (过多的) daytime sleepiness as a sign of disturbed or inadequate sleep. But a new study suggests it could also signal depression or even diabetes (糖尿病), regardless of whether an individual doesn't sleep well.
Among a random sample of 16, 500 men and women ranging in age from 20 to 100 years old from central Pennsylvania, 8.7 percent had excessive daytime sleepiness.
Researchers, who considered a wide range of possible reasons for why these individuals were excessively sleepy during the daytime, found that excessive daytime sleepiness was more strongly associated with depression, diabetes and overweight than with sleep-disordered breathing.
Depression was by far the most significant risk factor for excessive daytime sleepiness, researchers reported in the Journal of Clinical Endocrinology and Metabolism. The likelihood of being excessively sleepy during the daytime was more than three times higher in those who reported they were being treated for depression. These searchers also observed strong ties between excessive daytime sleepiness and diabetes. Individuals reporting treatment for diabetes were close to two times more likely to report excessive daytime sleepiness than those who were not being treated for diabetes. Being overweight also increased the likelihood of excessive daytime sleepiness.
Excessive daytime sleepiness was more common in people younger than age 30, who were in a state of unmet sleep needs and depression. As for the over 75 crowd, increasing medical illness and health problems were the causes.
Sleep-disordered breathing—brief episodes when breathing stops during sleep—was not a significant player in excessive daytime sleepiness. This was consistent with prior studies that had reported only weak associations between sleep-disordered breathing and excessive daytime sleepiness.
