After following 8,000 children from kindergarten to third grade, researchers concluded that kids who watched the most TV were at the greatest risk of being or becoming overweight. Children who ate fewer meals with their families also were at risk for becoming overweight.
"Other research has shown that children who eat meals with their families eat more healthy foods than children who don't eat as many meals with their families," said Sara Gable, associate professor of human development and family studies in the MU College of Human Environmental Studies. "I suspect there are other benefits of family meal times that protect children from developing some of the habits that could lead to weight problems."
The researchers grouped children into three categories to determine the factors associated with becoming overweight: children who were not overweight during kindergarten and first grade but were overweight by the third grade; children who became overweight during kindergarten and stayed that way through the third grade; children who were never overweight.
"Children who were never overweight between kindergarten and third grade were watching, as per parent reports, roughly two hours of television per day, or about 14 hours during a typical week," Gable said. "The children who were persistently overweight were watching about 16 hours of television per week."
Members of the persistently overweight groups also lived in neighborhoods that parents perceived as less safe for outdoor play.
"These results suggest that some overweight children have fewer options for active play when they are at home," Gable said.
The study, which was funded by the United States Department of Agriculture, was published in this month's issue of the Journal of the American Dietetic Association.

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.
Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.
Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...
The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.
Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.
Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
