Tots who sleep less have more behavior problems, says study

11.07.2013
Increased 'externalizing' problems for preschoolers who sleep less than average

Four-year-olds with shorter than average sleep times have increased rates of "externalizing" behavior problems, reports a study in the July Journal of Developmental & Behavioral Pediatrics, the official journal of the Society for Developmental and Behavioral Pediatrics. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health.

"Preschool children with shorter nighttime sleep duration had higher odds of parent-reported overactivity, anger, aggression, impulsivity, tantrums, and annoying behaviors," according to the new research by Dr. Rebecca J. Scharf of University of Virginia, Charlottesville, and colleagues. They recommend that parents and health care providers discuss steps to improve sleep habits for preschool-age children with behavior problems.

Shorter Sleep Times, More Behavior Problems

The researchers analyzed parent responses from a nationally representative study of approximately 9,000 children, followed from birth through kindergarten age. When the children were four years old, nighttime sleep duration was estimated by asking the parents what time their child typically went to bed and woke on weekdays.

On a standard child behavior questionnaire, parents rated their child on six different "externalizing" behavior problems such as anger and aggression. (Externalizing behavior problems are outward behaviors, distinguished from "internalizing" problems such as depression and anxiety.) The relationship between sleep duration and behavior scores was assessed, with adjustment for other factors that might affect sleep or behavior.

The average bedtime was 8:39 pm and wake time 7:13 am, giving a mean nighttime sleep duration of about 10½ hours. Eleven percent of children were considered to have "short sleep duration" of less than 9¾ hours (calculated as one standard deviation below the average).

On the child behavior questionnaire, 16 percent of children had a high score for externalizing behavior problems. Behavior problems were more common for boys, children who watched more than two hours of television daily, and those whose mothers reported feeling depressed.

After adjustment for other factors, "Children in the shortest sleep groups have significantly worse behavior than children with longer sleep duration," Dr Scharf and colleagues write. The effect was greatest for aggressive behavior problems, which were about 80 percent more likely for children with nighttime sleep duration of less than 9¾ hours.

Shorter sleep times were also associated with 30- to 46-percent increases in rates of the other externalizing behaviors studied, including overactivity, anger, impulsivity, tantrums, and annoying behaviors. In a linear analysis, as sleep duration increased, troubling behaviors decreased.

Previous studies in smaller groups of children have identified shorter nighttime sleep duration as a risk factor for behavior problems in preschool children. The average 10½-hour sleep time in this nationally representative sample is less than in studies performed in past decades, and less than currently recommended for four-year-olds.

The new results, along with other recent studies, add to the evidence that preschoolers who sleep less will have more behavior problems, including disruptive behaviors like aggression and overactivity. Although the study can't draw any conclusions about causality, "there is good reason to believe that short nighttime sleep duration leads to externalizing behaviors," the researchers write.

Dr Scharf and coauthors recommend that doctors and health care providers ask about bed and wake times when talking to parents about young children with behavior problems. They add, "Advocating for regular sleep habits, healthy sleep hygiene, and regular bedtime routines may be helpful for young children."

About the Journal of Developmental & Behavioral Pediatrics

Written for physicians, clinicians, psychologists and researchers, each issue of the Journal of Developmental & Behavioral Pediatrics is devoted entirely to the developmental and psychosocial aspects of pediatric health care. Each issue brims with original articles, case reports, challenging cases and reviews—the latest work of many of today's best known leaders in related fields—that help professionals across disciplines stay current with the latest information in the field. Relevant areas covered include learning disorders, developmental disabilities, and emotional, behavioral, and psychosomatic problems. Journal of Developmental & Behavioral Pediatrics is the official journal of the Society for Developmental and Behavioral Pediatrics.

About The Society of Developmental and Behavioral Pediatrics

The Society for Developmental and Behavioral Pediatrics (SDBP) is an international organization dedicated to improving the health of infants, children, and adolescents by promoting research, teaching and clinical practice in developmental and behavioral pediatrics. Comprised of more than 700 members, the society strives to promote an understanding of the social, educational, and cultural influences on children

Im Focus: Can the immune system be boosted against Staphylococcus aureus by delivery of messenger RNA?

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.

Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
