Hyperactivity associated with shorter nights for young boys

30.11.2009
Canada-France study published in Pediatrics journal

Hyperactive boys don't get enough sleep, which can worsen their condition according to new research. Published in the November issue of Pediatrics, the study is the first to examine a large sample of children and to study the link between lack of sleep and hyperactivity.

As part of the investigation, 2057 mothers answered yearly questionnaires concerning sleep duration and hyperactivity of their children. Data was collected until kids reached five years of age and was analyzed by a team of scientists from the Université de Montréal, its affiliated Hôpital du Sacré-Cœur de Montréal and Sainte Justine University Hospital Research Center, as well as the Université Laval and the French National Institute for Health and Medical Research (INSERM).

" Hyperactivity problems may interfere with night-time sleep," says senior author Jacques Montplaisir, a professor in the Université de Montréal Department of Psychiatry and director of the Sleep Disorders Center at Hôpital du Sacré-Cœur de Montréal. "We found that children who didn't sleep long were generally hyperactive boys who lived under adverse family conditions."

"On the other hand, short or fragmented sleep leads to sleepiness, which could manifest as hyperactivity in boys," explains Dr. Montplaisir, noting children who slept persistently for at least 11 hours had low hyperactivity scores. "However, the risk of abbreviated sleep in highly hyperactive children is stronger than the risk of hyperactivity among kids with short sleep duration."

The research team found that boys (more than girls) whose mothers had low education, insufficient family income and whom were comforted outside the bed or joined the parental bed after an awakening at night when they were young were more at risk of having both short sleep duration and high hyperactivity.

Study respondents were a mostly (92.1 percent) homogenous pool of mothers who were white and French-speaking Quebecers. Questions asked of mothers included: how long does your child sleep during the night (on average); in the past three months, how often would you say your child was restless or hyperactive; couldn't stop fidgeting; impulsive or acted without thinking; had difficulty waiting for his/her turn at games; couldn't settle down to do anything or couldn't wait when promised something?"

Côté, Dominique Petit, Xuecheng Liu, Richard E. Tremblay and Jacques Y. Montplaisir of the Université de Montréal.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Im Focus: Three Magnetic States for Each Hole

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
