WASHINGTON, Oct. 3 (Xinhua) -- Overweight or obesity may put children at three times greater risk for high blood pressure than those of normal weight, according to researchers from the Regenstrief Institute and Indiana University (IU) School of Medicine.Their study will appear in the November issue of Hypertension: Journal of the American Heart Association with advance online publication on Monday.More than 1,100 healthy Indiana school children were followed for nearly five years. The researchers found that when body mass index (BMI) reached or exceeded the 85th percentile for the age and gender of the child -- designated as being overweight -- the risk of high blood pressure nearly tripled. Obesity was defined as a BMI percentile higher than 95th. BMI is a measurement of body fat calculated from weight and height.Among study participants, 14 percent of overweight or obese children were pre-hypertensive or hypertensive, compared with 5 percent of normal weight children. These findings were consistent across age, gender and race.The average age at time of study enrollment was 10.2 years. Each child was assessed approximately eight times during the course of the study. All were healthy children and none were taking medication affecting blood pressure."Higher blood pressure in childhood sets the stage for high blood pressure in adulthood," said Regenstrief Institute Investigator Wanzhu Tu, professor of biostatistics at IU School of Medicine, who led the study. "Targeted interventions are needed for these children. Even small decreases in BMI could yield major health benefits."The researcher also found that leptin, a protein hormone which is involved in body weight regulation and metabolism, was positively associated with increased blood pressure in overweight and obese children.

SANYA, Hainan, Dec. 4 (Xinhua) -- The five BRICS nations intend to focus and work together on developing alternative energy sources.When Bu Xiaolin, vice governor of China's coal-rich Inner Mongolia autonomous region, spoke over the weekend in front of hundreds of BRICS delegates on regional energy strategies, she mentioned little of the fossil fuels that have long contributed to the region's growth.Like many other speakers at the 1st BRICS Friendship Cities and Local Governments Cooperation Forum, which ran from Dec. 1-3 in Sanya, Hainan province, she devoted large part of her speech to discussing wind and solar energy."Facing the prospects of running out of fossil energy and the related environmental issues, developing new energy is an inevitable choice," said Bu.The forum at this seaside resort over the weekend attracted hundreds of local governors, scholars and business people from the BRICS nations -- Brazil, Russia, India, China and South Africa -- to discuss city-to-city cooperation, and new energy was among the top agenda topics.Consensus had been reached at the forum that the five countries should strengthen dialogue and cooperation for provincial and local partnerships, including infrastructure, green economy and technology transfer."We are very willing to cooperate with BRICS countries on new energy innovations, promotion and market development," said Bu.According to Bu, Inner Mongolia has huge potential in new energy, with 380 million kilowatts of exploitable wind power resources, accounting for more than half of China's on-shore wind power resources.The region is aiming for a total installed capacity of 33 million kilowatts for wind power and one million kilowatts for solar power by the end of 2015, she added.At national level, the Chinese central government expects to bring the country's total wind power installed capacity up to 150 million kilowatts in the next five years, according to national development plans.Meanwhile, in Brazil, there is movement to replace fossil energy with new energy in daily use, said Jailson Lima Da Silva, State Representative of the National Union of State Legislatures of Brazil.The country is working to increase the nation's wind power capacity, and new energy is expected to account for 65 percent of the nation's total energy consumption, he said."Brazil is optimistic on wind power exploitation, which will be one of the major fields of future investment," he said.Silva expressed hopes to work with China on new energy, especially solar power and biomass energy. "Brazil has large potential in solar energy, while China is a leading producers of solar equipment," he said.According to Mlibo Qoboshiyane, a member of the Executive Council of Eastern Cape, South Africa, the African nation is also investing extensively in wind and solar energy.South Africa has just unveiled a 12-billion-U.S.-dollar program on renewable energy development, which would largely be spent on wind and solar power and reduce the use of traditional energies, said the official.It would be helpful to exchange technologies and valuable information between the BRICS countries to keep consumption of new energies sustainable and affordable, he said. 

BEIJING, Oct. 25 (Xinhuanet) -- Steve Jobs, Apple's co-founder and former CEO, may be one of the great men who will still be influential after their deaths.The new biography of Steve Jobs is likely to be the top-selling book 2011 of Amazon.com Inc, an online book retailer, according to Amazon spokeswoman Brittany Turner Monday."It could very likely be our top-selling book of the year," Turner said in a statement cited by the Reuters.Steve Jobs, written by Walter Isaacson, former Time magazine managing editor, was landed on shelves in bookstores Monday.But its digital version was reported to be released late on Sunday on Apple's iBooks online store and Amazon's Kindle eBook store.Since its release, the biography, both electronic and physical versions, has performed very well in Amazon.It is the best-selling book on Amazon.com and the top-selling electronic book on the Kindle as well. According to the Reuters, Isaacson was asked by Jobs to consider writing a biography for Apple's former CEO in 2004, when Jobs was going to be operated on for pancreatic cancer.Then Isaacson had more than 40 exclusive interviews with Steve Jobs. The last such interview was on October 5, one week before the giant's death.

BEIJING, Nov. 13 (Xinhua) -- A campaign that aims to boost the public's role in safeguarding food safety and promote awareness of the issue was launched at the 9th China Food Safety Annual Conference, which closed on Sunday.Food safety has a bearing on people's health as well as the nation's sound and harmonious development, said Shi Xiushi, chairman of the Financial and Economic Committee of China's National People's Congress (NPC), at the opening, calling for efforts to raise companies' sense of responsibility and consumers' awareness in preventing and dealing with food safety crimes.The new campaign is part of a broader five-year program (2011-2015) of food safety education announced by the State Council Food Safety Commission (SCFSC) in May.The program aims for more than 80 percent of the public to be aware of basic food safety by 2015, with the rate for primary and high-school students reaching up to 85 percent or more.ARDUOUS WORKFood safety has become a growing public concern in China following a string of scandals over recent years. In the latest one, illegal workshops were found making and selling "gutter oil," which is processed from leftovers dredged from gutters.Gu Xiulian, former vice chairwoman of the NPC's Standing Committee, the country's top legislature, said ensuring safety is the top priority for the food sector, the country's pillar industry with an output of 550 million yuan (97.3 million U.S. dollars) in the first nine months of 2011.The development of the nation's food safety has failed to keep up with the demands of a public whose living standards have improved substantially in recent years, said Shi.Pledging to do everything it can to ensure food safety, the government takes a zero-tolerance approach to companies that sell unsafe food. In 2010 alone, authorities across the country investigated and handled 130,000 cases of food safety violations, shutting down more than 100,000 companies, according to the SCFSC."The food industry's overall development level is relatively low. There are weak links in the sector's credibility, management, detection techniques and even the laws and regulations," said Pu Changcheng, deputy director of the Administration of Quality Supervision, Inspection and Quarantine.Pu's points are exemplified by China's agricultural industry, which is largely based around small-scale production managed by disparate bodies. It would be a formidable task to eradicate the sector's safety issues.The catering business also faces a similar plight. The country has issued licenses to 2.2 million catering companies, most of which are small and individually operated, making safety supervision extremely difficult, according to Bian Zhenjia, deputy head of the State Food and Drug Administration.
