A new study by British researchers will be the largest-ever to examine whether chronic use of mobile phones and other wireless devices affects kids’ and teenagers’ brain development. Reuters has more:
The Study of Cognition, Adolescents and Mobile Phones, or SCAMP, project will focus on cognitive functions such as memory and attention, which continue to develop into adolescence – just the age when teenagers start to own and use personal phones.
While there is no convincing evidence that radio waves from mobile phones affect health, to date most scientific research has focused on adults and the potential risk of brain cancers.
Because of that, scientists are uncertain as to whether children’s developing brains may be more vulnerable than adults’ brains – partly because their nervous systems are still developing, and partly because they are likely to have a higher cumulative exposure over their lifetimes.
“Scientific evidence available to date is reassuring and shows no association between exposure to radiofrequency waves from mobile phone use and brain cancer in adults in the short term – i.e. less than 10 years of use,” said Paul Elliott, director of the Centre for Environment and Health at Imperial College London, who will co-lead the research.
“But the evidence available regarding long term heavy use and children’s use is limited and less clear.”
Mobile phone use is ubiquitous, with the World Health Organisation estimating 4.6 billion subscriptions globally. In Britain, some 70 percent of 11 to 12 year-olds now own a mobile phone, and that figure rises to 90 percent by age 14.

Frequent Internet use, stressed-out parents who don’t have time to play outside, and too much time spent riding in cars are all cited by a non-profit organization’s Physical Activity for Children and Youth report card as contributing factors to poor physical activity and fitness levels among American kids. Reuters has more:
Only one quarter of children aged 6 to 15 meet the current guidelines of 60 minutes of moderate physical activity per day, said Dr. Russell R. Pate, chairman of the non-profit National Physical Activity Plan (NPAP) Alliance, which issued the first U.S. report card on Physical Activity for Children and Youth.
“Fifty percent of waking hours are spent in sedentary activity,” said Pate, professor in the Department of Exercise Science in the Arnold School of Public Health at the University of South Carolina.
Fitness experts say it is up to parents and policy makers to get their children to be more active.
“It’s not about grading the kids,” said Dr. Peter Katzmarzyk, a fellow of the American College of Sports Medicine and chairman of the research committee that issued the report card.
“Kids want to be active, if they’re given the opportunity.” he said. “This is for us to change.”

New York City has been named in a national survey as the most expensive city in the nation in terms of the cost of hiring a babysitter. More from Time.com:
The average hourly babysitting rate for one child in New York is $15.34, based on a survey by UrbanSitter, which compiled data from nearly 7,500 families. That’s about $4.50 per hour more expensive than the cheapest big American city, Denver, whose babysitters charge parents an average of $10.84 per hour.
San Francisco parents pay $14.99 for one kid, Los Angeles parents pay $13.53, Washington, DC parents pay $13.83, and on the lower end, Chicago parents bay $11.91 and San Diego parents pay $11.11.
UrbanSitter also found that parents go through babysitters pretty quickly, with only 6 percent saying they’ve had the same one for over 5 years. Parents also like to go out a lot: more than a fourth of parents say they hire a babysitter once a week or more. And 30 percent of parents say they would not hire a “manny”—a male babysitter.

Connecticut legislators have sent to the governor a measure that would prohibit public schools from offering chocolate milk and some juices to children, citing the beverages’ links to imbalanced nutrition when it comes to fat, salt, and sugar. More from CBS News:
If he signs it, Connecticut would be the first state in the country — not just a single school district –to ban chocolate milk in school cafeterias. The law would go into effect next September.
Politicians in the state faced pressure to pass school nutrition rules or risk forfeiting funds from the Healthy, Hunger-Free Kids Act, a federal policy that sets requirements for the United States Department of Agriculture’s Nutrition Programs, which includes its school lunch program. However, the USDA points out that the Act does not ban individual food items. A USDA spokesperson told CBS News that it does require flavored milks to be non-fat.
Under the state proposal, schools in Connecticut would only be allowed to serve low-fat, unflavored milk and beverages without artificial sweeteners, added sodium or more than four grams of sugar per ounce.
Chocolate milk contains high fructose corn syrup and up to 200 milligrams of sodium, which means it won’t make the cut.
Some child nutritionists think the proposed law will backfire and jeopardize the health of children in the state. Jill Castle, a registered dietician and nutritionist from New Canaan, Conn., told CBS affiliate WFSB that when chocolate milk is removed from the cafeteria the overall consumption of milk goes down.
“From a nutrient profile, you’re getting calcium, vitamin D, potassium, phosphorous, protein, and other nutrients,” said Castle.
But some food experts disagree. Marlene Schwartz, director of Yale University’s Rudd Center for Food Policy and Obesity, says the ban means that the food industry will simply need to adjust.
“This isn’t going to keep out flavored milk,” Schwartz told the Hartford Courant. “All it’s going to do it make sure the flavored milk that’s in there is not going to have added salt.”

Babies who are circumcised rarely have medical complications, though older kids who undergo the procedure are more likely to have issues, according to a new study published in the journal JAMA Pediatrics. More from Reuters:

Previous research found wide variations in the rates of complications following male circumcisions. Those studies were often small and based on patients from a single hospital.
For the new study, published Monday in JAMA Pediatrics, researchers used data from U.S. insurance claims for babies younger than one year old, children between ages one year and nine years and older children 10 years and older. The findings do not include children who underwent ritual circumcisions in a non-medical setting.
Overall, the researchers had data on more than 1.4 million circumcised males. The vast majority were newborns.
“This is what we found about the risks of circumcision,” said Charbel El Bcheraoui, the study’s lead author from the University of Washington in Seattle. “It’s low overall, but it increases with age at circumcision.”
About 0.4 percent of boys experienced circumcision complications when the procedure was performed within the first year of life. The risk increased about 20-fold among boys between one year and nine years of age. It was 10-fold higher among males 10 years old and older, compared with infants.
“What we assume is it’s probably because between one and 10 years of age is the age when caring after procedure is the most complicated,” Bcheraoui said.
Circumcision, or removing the foreskin from the penis, is a ritual obligation for infant Jewish boys and is also a common rite among Muslims, who account for the largest share of circumcised men worldwide.
The wider U.S. population adopted the practice due to potential health benefits, such as reducing the risk of urinary tract infections in infants and cutting the risk of sexually transmitted disease later in life, including HIV.
But the practice has been the focus of heated debate, including efforts to ban it in San Francisco and Germany. The rate of circumcisions performed on newborns in U.S. hospitals has dropped over the last three decades.
The American Academy of Pediatrics updated its recommendations in 2012 to say the benefits of male circumcision justify families having access to the procedure if they choose.
According to the JAMA Pediatrics study, about 0.5 percent of the procedures ended with some type of adverse event regardless of age, but the rates for specific complications varied.
Damage to the urethra occurred in about 0.8 per 1 million circumcisions. Leaving behind too much foreskin occurred in about 702 per 1 million circumcisions.
