The study was performed by a team of researchers from The Medical Research Council Epidemiology Unit and The University of East Anglia, coordinated by Esther van Sluijs. During the Summer term 2007, they studied the diet, physical activity and body shape of 2064 Year 5 pupils (aged 9-10 years) in 92 schools across the county of Norfolk.
They also investigated their socioeconomic and ethnic backgrounds, and school and home neighborhood environments. According to van Sluijs, “To date, the extent of the problem of physical inactivity and unhealthy dietary habits in children has been largely unknown. Good data about physical activity, assessed using valid and reliable measures in large samples, are scarce - especially in children”.
The aim of the SPEEDY study was to generate valid data about current diet and exercise patterns, and the factors that are most strongly associated with them. The authors sought to better understand why some children have a healthier lifestyle than others so that they can promote changes in important health behaviors.
They write, “Our results showed that more than two-thirds of children adhere to the physical activity guideline of accumulating at least 60 minutes of moderate-to-vigorous physical activity each day, but that daily consumption of fruit or of vegetables was only reported by 56.8% and 49.9% of the children, respectively.”
Boys were more likely to be physically active and of normal weight than girls. In contrast, boys’ reported daily consumption of ‘healthy’ foods was lower, and their consumption of snacks and unhealthy food items such as soft drinks was higher than that of girls. In addition, children from a higher socioeconomic background were more likely to eat fruit and vegetables daily.
The authors say, “The fact that almost 70% of children meet national physical activity guidelines indicates that a prevention of decline, rather than increasing physical activity levels, might be an appropriate intervention target, although there is some uncertainty over whether these recommended levels are really sufficient. Promotion of daily fruit and vegetable intake in this age group is also warranted, possibly focusing on children from lower socioeconomic backgrounds.”

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
