BEIJING, Aug. 16 (Xinhuanet) -- It is widely accepted that obesity leads to an increased risk of health complications, but new studies quoted by media Tuesday challenge the conventional notion.“Our studies challenge the idea that all obese individuals need to lose weight,” said Dr. Jennifer Kuk, assistant professor in York University’s School of Kinesiology & Health Science in Toronto.  One of the studies used data from the Aerobics Center Longitudinal Study consisting of 29,533 individuals and assessed their mortality in 16 years.It found no difference in death risks between normal-weight individuals and obese ones. "Since the obese people did not have greater risk of dying than normal weight individuals, they don’t need to lose weight," said Dr. Kuk.But the finding did not give obese individuals a “free license” to gain weight, Dr. Kuk added. Maintaining weight, eating right and exercising may be better than trying to lose weight in the long run, said Dr. Kuk.

SYDNEY, July 1 (Xinhua) -- Breastfeeding mothers should limit their use of codeine-containing painkillers to four days as they can cause harm, an Australian doctor warned on Friday.The warning is being discussed at a meeting of anesthetists in Sydney."New mothers should limit their use of codeine-containing painkillers to no more than four days and, if they feel drowsy while taking this medication, cease its use and have their baby examined by a doctor for signs of drowsiness," Sydney's Royal North Shore Hospital anesthetist Dr. Gavin Pattullo said."This is because codeine needs to be metabolized by the liver into morphine to offer pain relief and this liver conversion process is very unpredictable," Pattullo said."Some patients' livers produce large amounts of morphine after taking codeine, causing drowsiness, while others fail to produce any morphine at all."Pattullo said for breastfeeding mothers, a large dose of morphine could make its way into the baby and result in the baby's death by overdose."While new mums shouldn't be unnecessarily alarmed, they need to be aware that codeine-containing painkillers in certain circumstances can cause harm," he said.Breastfeeding mothers are being advised to see a doctor if their baby gets sleepy while taking the painkillers.

BEIJING, Aug. 30 (Xinhuanet) -- The United Nations is warning authorities to be on high alert of bird flu as the virus appears to be returning.The UN Food and Agriculture Organization said in a statement Monday a mutant strain is spreading across parts of Asia, and there could be a spill-over to humans.However, it said at this stage, there's no need for any alarm.A mutant strain of H5N1, which can apparently sidestep defenses of existing vaccines, is spreading in China and Vietnam, it said.It said the variant of the virus appears able to side step Vaccines.The UN is concerned the new form of the virus could spread to Cambodia, Thailand and Malaysia, as well as the Korean Peninsula and Japan."Wild birds may introduce the virus, but people's actions in poultry production and marketing spread it," said FAO's chief veterinary office Juan Lubroth in urging greater preparedness and surveillance, according to media reports.Outbreaks of the virus peaked in 2006 before it was eradicated from most countries.

SAN FRANCISCO, July 7 (Xinhua) -- Apple announced Thursday that over 15 billion applications have been downloaded from its App Store by more than 200 million Apple mobile devices users worldwide."Thank you to all of our amazing developers who have filled it with over 425,000 of the coolest apps and to our over 200 million iOS users for surpassing 15 billion downloads," said Phillip Schiller, Apple's senior vice president of worldwide product marketing, in a statement.Launched on July 10, 2008, Apple's digital application distribution platform has been growing at a fast speed. It took nine months to hit one billion downloads and five billion in June 2010. In January, Apple gave a 10,000-U.S. dollar App Store gift card to a user who downloaded the 10 billionth application.In Thursday's statement, the Cupertino, California-based company said it had paid developers 2.5 billion dollars to date.Apple's mobile market place is far ahead of Google's Android Market. At its annual I/O conference in May, Google said there had been 4.5 billion app installs so far. But Google said the growth of its mobile operating system and applications is accelerating with its store hitting another billion downloads every 60 days.Currently, Apple is in a legal battle against Amazon over the use of "Appstore," which the online retailer launched in March to sell mobile applications to Google's Android platform users.On Wednesday, a federal judge denied Apple's request to immediately stop Amazon from using the term "Appstore."Meanwhile, Amazon, Microsoft, HTC, Nokia and Sony Ericsson have filed complaints against Apple in Europe, seeking to get Apple's trademarks for "App Store" and "Appstore" invalidated.

WASHINGTON, June 14 (Xinhua) -- Short sleep duration may contribute to the development or worsening of hyperactivity and inattention during early childhood, suggests a research abstract that was presented Tuesday at SLEEP 2011, the 25th Anniversary Meeting of the Associated Professional Sleep Societies LLC.Results show that less sleep in preschool-age children significantly predicted worse parent-reported hyperactivity and inattention at kindergarten. The sample consisted of approximately 6,860 children, and analyses controlled for gender, ethnicity and family income."Children who were reported to sleep less in preschool were rated by their parents as more hyperactive and less attentive compared to their peers at kindergarten," said lead author Erika Gaylor, senior researcher for SRI International, an independent, nonprofit research institute in Menlo Park, California. "These findings suggest that some children who are not getting adequate sleep may be at risk for developing behavioral problems manifested by hyperactivity, impulsivity, and problems sitting still and paying attention." According to the authors, attention-deficit/hyperactivity disorder (ADHD) is not generally diagnosed until the school-age years. However, the onset of developmentally inappropriate inattention, hyperactivity and impulsivity is often much younger. Sleep problems, particularly difficulty falling asleep and staying asleep, are frequently reported in children and adolescents with ADHD. However, the direction of causation, if any, has been difficult to determine. Longitudinal studies may provide a window into the direction of this complex relationship.Last year at SLEEP 2010, Gaylor reported that having a regular bedtime was the most consistent predictor of positive developmental outcomes at four years of age. Having an earlier bedtime also was predictive of higher scores for most developmental measures.
