Screen Hours and Sleep Symptoms: The US National Health and Nutrition Examination Survey.

Few studies have examined the relationship between television viewing, computer use, and sleep symptoms. We hypothesized that television and computer time was associated with sleep symptoms. Screen hours were the sum of daily TV hours and computer hours. A total of 4342 participants 20 years and older had data on screen hours. After adjusting for confounders, 4 or more screen hours were significantly associated with increased odds of reporting long sleep latency, nighttime awakening, high sleep hours, and snoring (P < .05). These findings suggest that increased screen/TV time is an important risk factor for sleep symptoms.
