Research from the American Academy of Pediatrics analyzing responses from the parents of caregivers of 49,050 children aged six to seventeen in the combined 2016-2017 National Survey of Children's Health revealed that only 47.6% of American children slept for nine hours one most days, meaning a significant number was sleep deprived. Compared with children who did not get enough sleep most nights, those who did were 44% more likely to be curious about new things, 33% more likely to finish their homework, 28% more likely to care about their academic performance, and 14% more likely to finish the tasks they started. The researchers identified the risk factors associated with sleep deprivation among children to be the low educational attainment of parents or caregivers, being from families living below the federal poverty line, higher digital media usage, more negative childhood experiences, and mental illnesses.
