That's according to the results of a study conducted by Chantelle Hart, associate professor of public health at Temple's Center for Obesity Research and Education (CORE), published today in Pediatrics.
The study, entitled "Changes in Children's Sleep Duration on Food Intake, Weight, and Leptin," is the first known study to examine the impact of sleep on children's eating behaviors by manipulating the amount of sleep that study participants were able to get.
The study, which was conducted while Dr. Hart was at the Miriam Hospital and Alpert Medical School of Brown University, involved 37 children, ages 8 to 11; 27 percent of whom were overweight or obese.
For the first week of the study, children were asked to sleep their typical amount. Next, during the second week, the group was randomized to either reduce or lengthen their sleep time; participants completed the opposite sleep schedule during the third and final week of the study.
The results were conclusive: During the week that the children increased their sleep, they reported consuming an average of 134 fewer calories per day, weighed a half pound less, and had lower fasting levels of leptin, a hunger-regulating hormone that is also highly correlated with the amount of adipose tissue, when compared to the week of decreased sleep.
"Findings from this study suggest that enhancing school-age children's sleep at night could have important implications for prevention and treatment of obesity," said Hart. "The potential role of sleep should be further explored."
So what's next? Hart is working on a study funded by the National Heart Lung and Blood Institute of the NIH using a brief behavioral intervention to get kids to increase their sleep to determine if there are significant changes in eating, activity behaviors and weight status.
While it is still early in the testing, Hart hints that the intervention looks promising:
"Given all of its documented benefits, in many ways, you can't lose in promoting a good night's sleep."
Funding for this research was provided by a grant from the American Diabetes Association.

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.
Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
