Young children who attend daycare on a regular basis are 50% more likely to be overweight compared to those who stayed at home with their parents, according to a study by researchers at the University of Montreal and the CHU Sainte-Justine Hospital Research Centre.
"We found that children whose primary care arrangement between 1.5 and 4 years was in daycare-center or with an extended family member were around 50% more likely to be overweight or obese between the ages of 4-10 years compared to those cared for at home by their parents," said Dr. Marie-Claude Geoffroy, who led the study. "This difference cannot be explained by known risk factors such as socioeconomic status of the parents, breastfeeding, body mass index of the mother, or employment status of the mother."
The researchers studied 1,649 families with children born in 1997-1998 in Québec. The sample was representative of the majority of Québec children. Mothers were interviewed about the care of their children at 1.5 years, 2.5 years, 3.5 years, and 4 years. The children were classified according to the type of care in which they had spent the most total hours, i.e., in a 'daycare centre' (30%), in 'family daycare' (35%), with an 'extended family member' (11%), with a 'nanny' (5%), or with their 'parents' (19%). During the six years that followed, the researchers measured the children's weight and height. Children with excessive weight or obesity were identified using international standards (IOTF).
To date, the mechanisms responsible for the increased proportion of overweight children in some child care situations remains unknown. "Diet and physical activity are avenues to follow," says Dr. Sylvana Côté, who co-directed the study. "Parents don't have to worry; however, I suggest to parents they ensure their children eat well and get enough physical activity, whether at home or at daycare."
The researchers believe that daycare has the potential to reduce weight problems in children, possibly through the promotion of physical activity and healthy eating. "The enormous potential of the impact of daycare on the nutritional health of children 2-5 years of age was also noted by the Extenso unit of the University of Montreal Nutrition Reference Centre, which has developed a Web portal specifically devoted to children in daycare," said Dr. Jean Séguin, who also co-directed this study.
About the study
The study was published in the Journal of Pediatrics and was supported in part by the Fonds de recherche du Québec - Santé, the Institut de la statistique du Québec, and the Social Sciences and Humanities Research Council of Canada. Researchers from University College London, INSERM, Université Laval, Université Paris-Sud, the University of Ottawa, and University College Dublin contributed to the study. Dr. Geoffroy is financially supported by the Canadian Institutes of Health Research. The University of Montreal is officially known as Université de Montréal.

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
