Researchers led by The University of Manchester say that faster-growing children might be especially vulnerable to the fattening effects of the ‘obesogenic environment,’ that is causing society to get fatter.
Lead researcher Dr Iain Buchan, Director and Senior Lecturer in Public Health Informatics at the Northwest Institute for Bio-Health Informatics at Manchester said: “Our study shows that the UK needs to change its eating and exercise habits. The more children eat, the more they show the effects of what we are offering them – basically far too much unhealthy food and far too little chance to exercise.
“The largest increase in body mass index (BMI) in our study occurred in the tallest children, while that for the smallest hardly changed. Tall stature has therefore become important for child obesity. It shows a drive to adiposity (fatness) in young children involving both growth and appetite, with fast-growing and hungrier children more exposed to the obesogenic environment.”
The team, which also includes Great Ormond Street Hospital’s Institute of Child Health and The University of Liverpool, surveyed the weights of 50,000 three-year-olds from the Wirral (where BMI has been rising for 16 years) from 1988 to 2003.
They found that mean BMI rose by 0.7 kg/m2 while mean height fell by 0.5cm. Over the same period the weight-height correlation rose from 0.59 to 0.71 as the BMI of taller children rose.
Among the shortest 10% of the children mean BMI rose by 0.12 kg/m2, as against 1.38 kg/m2 among the tallest 10% - a 12-fold difference. Adjustment for age, sex, birth-weight, seasonality and deprivation did not alter their findings.
Dr Buchan added: “We have shown a strong relationship between child growth and obesity. The next research challenge is to work out exactly how this happens.
“We are looking at some deeper relationships between child growth and obesity with the data we have. Beyond this new data are required.
“One area in particular that needs more study is very early feeding. Animal studies show that obesity might be prevented permanently by reducing the amount of calories consumed by young in the first few weeks of life - exploring whether or not this is a safe and effective approach to preventing obesity in humans needs careful research.”

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
