Children's sleep disorders

NEW YORK, Mar 9 (Reuters) When children have sleep problems, their parents -- especially mothers -- often have sleep-deprived nights too, research shows.

In a study of families with children seen at a sleep clinic, researchers found that when children had multiple sleep problems, their parents were more likely to have daytime drowsiness.

Mothers were generally more affected than fathers, possibly because they were the ones who typically responded to their children's problems in the middle of the night, the researchers speculate.

''A child's sleep problem affects the whole family,'' said lead study author Dr. Julie Boergers, of Bradley Hasbro Children's Research Center and Brown Medical School in Providence, Rhode Island.

This is important, she told Reuters Health, because research shows that sleep disruptions and daytime sleepiness have negative effects on people's mood, behavior and health. For parents, sleep deprivation may cause them to have less patience with their child or spouse, and be less productive at work and at home, Boergers explained.

The study, published in the Journal of Family Psychology, is based on 107 families of children ages 2 to 12 who were evaluated at a sleep disorders clinic. The children's sleep problems ranged from the breathing disorder sleep apnea to night terrors and sleepwalking to behavioral issues like refusing to go to bed.

When parents were surveyed about their own sleep habits and daytime alertness, it turned out that those whose children had more than one sleep problem tended to suffer more daytime sleepiness than other parents.

This was particularly true of mothers, even though they reported sleeping roughly the same number of hours that fathers did.

It's possible that mothers did have more sleep interruptions than fathers, even though they logged roughly the same number of hours in bed, according to Boergers and her colleagues. While fathers in general may be taking on more child-rearing responsibilities, they note, moms are probably still the ones who more often get out of bed to check on their child.

According to Boergers, some signs of a childhood sleep disorder include excessive daytime sleepiness, difficulty falling asleep, frequent nighttime waking or snoring.

''It's also important to recognize that some children who demonstrate daytime behavior problems or mood disturbances may suffer from an underlying sleep disorder,'' she said.

Parents who suspect their child may have a sleep disorder ''shouldn't hesitate'' to seek help for it, Boergers said, as there are effective behavioral therapies and medications available.
