Toddlers with Sleep Problems Have More Injuries

Newswise – A new study by psychologists at the University of Alabama at Birmingham (UAB) finds that toddlers who persistently wake up one or more times a night, at least once a week are at a greater risk for accidental injuries severe enough to require medical attention. The results of the study are published in the current advanced access edition of the Journal of Pediatric Psychology.

Injuries are the leading cause of death among children in the United States, according to the National Center for Injury Prevention and Control.

"The study reinforces the need to aggressively treat sleep difficulty in young children as a means to encourage not just cognitive and social development, but also to maintain physical health," said UAB psychologist David Schwebel, Ph.D., the study’s principal investigator.

In the study, Schwebel examined a sample of 799 children, which included 408 boys and 391 girls. The children’s parents were surveyed several times a year, beginning just after the children were born until their third birthday.

According to reports by the parents, 34 percent of the children were classified as having very mild to mild sleep problems. This group awakened one or more times a night at least once a week for five minutes or longer.

Two percent of the children were classified as having moderate to severe sleep problems, waking up at least twice a night, three or more times a week and remaining awake for 15 minutes or longer each time.

The study found that the children with very mild to severe sleep problems had nearly twice as many injuries as the 511 children in the study, 64 percent, who did not have sleep problems.

The link between sleep patterns and injury risk was demonstrated even when the researchers controlled for variables such as socioeconomic status, parenting styles and maternal stress and depression, Schwebel said.

More studies are needed to find out whether fatigue or other possibilities such as parent behavior, children’s personality or conditions in the home play a role in creating the link between nighttime awakenings and injuries.

Carl M. Brezausek, M.S., with the UAB Center for Educational Accountability, was the study’s co-author.
