An ongoing study, the European Youth Heart Study is examining the nature, strength, and interactions between personal, environmental, and lifestyle influences on later risk of these diseases. As part of this study, European researchers questioned 1,921 children from three regions in Portugal, Estonia and Denmark on the hours of TV viewed and measured their activity over a 4 day period. They also measured six metabolic-risk factors (body fatness, blood pressure, fasting triglycerides, inverted high-density lipoprotein (HDL) cholesterol, glucose, and insulin levels and calculated a metabolic risk score for each child based on these risk factors.
The researchers showed that there was a positive association between TV viewing and adiposity (fatness), but not with the overall risk score. However, the physical activity of the children was independently and inversely associated with systolic and diastolic blood pressure, fasting glucose, insulin, triglycerides and with the overall risk score, independently of obesity and other factors.
TV viewing has previously been linked to metabolic-risk factors in youth. However, it had been unclear whether this association was independent of physical activity and obesity. This study showed that TV viewing and physical activity should be considered as separate entities as they are differently associated with adiposity and metabolic risk. The authors conclude that “preventive action against metabolic risk in children may need to target TV viewing and physical activity separately.” These results will be presented during the International Diabetes Federation 19th International meeting in Cape Town on Thursday the 7th December.
In a related Perspective article, Andrew Prentice and Susan Jebb, who were not involved in the study, discuss further the implications of these findings.

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...
