BEIJING, Sept. 30 (Xinhuanet) -- The number of children being prescribed stimulants to treat attention deficit hyperactivity disorder (ADHD) has been steadily rising in the U.S. since 1996, researchers found.The finding was contained in a report released Wednesday in the U.S. medical journal Psychiatry.About 7.8 percent of children aged 4 to 17 in 2003 were diagnosed with ADHD, compared to 9.5 percent in 2007, according to the data gathered from the Health Resources and Services Administration's National Survey of Children's Health.And compared to 0.6 percent in 1987, 2.9 percent of children under 19 in 2002 have been prescribed stimulants, the report said.The finding raises the researchers' concern as stimulants have side effects such as decreased appetite, leeplessness and even heart-related damage, the report warned."Stimulant medications work well to control ADHD symptoms, but they are only one method of treatment for the condition. Experts estimate that about 60 percent of children with ADHD are treated with medication." says researcher Benedetto Vitiello, MD, of the U.S. National Institute of Mental Health."There is ongoing concern that these drugs may not be used properly, especially when they are prescribed to college students or children in their late adolescence who are more in charge of their care and may not be using the medications as prescribed." he added.

SAN FRANCISCO, Dec. 2 (Xinhua) -- About one in 10 mobile phone subscribers in the United States is now using an Apple iPhone, said a new survey released on Friday.Latest survey results from research firm comScore showed that for the three-month period ending in October, Apple remained the No. 4 handset maker in the U.S. with its share of mobile subscribers rising to 10.8 percent from 9.5 percent in the previous three months.Among the top five mobile phone brands in the U.S. market, Apple is the only one that saw its market share increase in the quarter, according to the survey.Samsung was still the top handset manufacturer with 25.5 percent of U.S. mobile subscribers, followed by LG and Motorola taking the second and third place with 20.6 percent and 13.6 percent of share respectively.Research in Motion (RIM), maker of Blackberry, ranked No. 5 with a share of 6.6 percent.Except Apple, market shares of the other four brands remained unchanged or dropped from the previous quarter.Apple's gain in the quarter might be driven by the introduction of new model iPhone 4S which went on sale on Oct. 14, and the addition of Sprint as a carrier in the U.S. market, some analysts said.The survey by comScore, which involved more than 30,000 U.S. mobile subscribers, found that 234 million Americans age 13 and older used mobile devices by the end of October.

SAN FRANCISCO, Nov. 11 (Xinhua) -- Apple on Friday said it will "continue to investigate" the unexpected iPhone battery drain as some users still see the problems after downloading a latest software update designed to address the issues."The recent iOS software update addressed many of the battery issues that some customers experienced on their iOS 5 devices. We continue to investigate a few remaining issues," said Apple in a statement made to technology news site AllThingsD.Apple released iOS 5.0.1, an update to its latest mobile operating system iOS 5 on Thursday. The update includes fixes for some bugs which are blamed for shortening the battery life of iPhones and other devices that use the system.Some users said the battery life of their iPhones look much better after the update. But according to some posts on Apple's official support forums, some iPhone owners still claimed the issue is persisting, saying they saw no difference at all after downloading the update.Complaints about the battery life of Apple's latest iPhone 4S smartphone have been piling up on the Internet in the past weeks.On Apple's official support forums, some iPhone 4S owners said their handsets' battery drained more than 10 percent every hour, even when in standby mode with some advanced features like Siri and location services completely deactivated.It is reported that Apple engineers contacted some iPhone 4S owners in Britain and installed a diagnosis file on their devices to send details back to the company's headquarters in Cupertino, California.Apple confirmed the iPhone battery issue last Wednesday, saying that a few bugs in the iOS system have caused the problem and it will release a software update in a few weeks.

BEIJING, Oct. 18 (Xinhuanet) -- Autism can likely develop when low birth weight babies are combined with other factors such as environment and genetic predisposition, new research suggests.Researchers from the University of Pennsylvania School of Nursing and School of Medicine identified 1,105 children who weighed less than 2,000 grams at birth between Oct. 1, 1984, and July 3, 1989.Sixteen years later, researchers were able to reach 623 of those children, and used a questionnaire to screen them for autism spectrum disorders.When 189 of the children turned 21 years old, 60 percent of those who screened positive for an autism spectrum disorder, and 24 percent of those who screened negative with the condition. All in all, the rate of autism spectrum disorders among the study participants with low birth weights was five times higher than the general.Autism spectrum disorder makes people have difficulty communicating, difficulty interacting in social situations, and restrictive or repetitive interests, said study co-author Jennifer Pinto-Martin, a researcher in the University.Those with mild autism spectrum disorders, "may only want to talk about one subject," Pinto-Martin said. "They're perfectly functional. They can go to college. They can hold a job." Premature babies are often born with low birth weights, though full-term babies can also have the condition. The research suggests a need not only for better prenatal care to reduce the number of premature babies, but also a need for early diagnosis and intervention for people with autism.
