WASHINGTON, Oct. 6 (Xinhua) -- The U.S. Food and Drug Administration (FDA) and the National Institutes of Health (NIH) announced Thursday a joint, large-scale, national study of tobacco users to monitor and assess the behavioral and health impacts of new government tobacco regulations.The initiative is the first large-scale NIH/FDA collaboration on tobacco regulatory research since the U.S. Congress granted FDA the authority to regulate tobacco products in an act in 2009. Scientists at NIH's National Institute on Drug Abuse and the FDA's Center for Tobacco Products will coordinate the effort."The launch of this study signals a major milestone in addressing one of the most significant public health burdens of the 21st century," said FDA Commissioner Margaret Hamburg in a statement. "The results will strengthen FDA's ability to fulfill our mission to make tobacco-related death and disease part of America's past and will further guide us in targeting the most effective actions to decrease the huge toll of tobacco use on our nation's health."Investigators will follow more than 40,000 users of tobacco- product and those at risk for tobacco use ages 12 and older. They will examine what makes people susceptible to tobacco use; evaluate use patterns and resulting health problems; study patterns of tobacco cessation and relapse in the era of tobacco regulation; evaluate the effects of regulatory changes on risk perceptions and other tobacco-related attitudes; and assess differences in attitudes, behaviors and key health outcomes in racial-ethnic, gender, and age subgroups."We are pleased to collaborate with the FDA on this study that may provide us with a better understanding of the impact of product regulation on tobacco prevention and cessation," said NIH Director Francis Collins.While smoking rates have dropped significantly since their peak in the 1960s, nearly 70 million Americans ages 12 and older were current users of tobacco products in 2010. As a result, death and disease caused by tobacco use is still a tremendous public health burden. Tobacco use is the leading preventable cause of disease, disability, and death in the United States. Cigarette smoking results in more than 443,000 premature deaths in the United States each year -- more than alcohol, illegal drug use, homicide, suicide, car accidents, and AIDS combined.

BEIJING, Oct. 26 (Xinhua) -- The State Council, or China's cabinet, has decided to create a food allowance for about 26 million needy students nationwide, according to a statement issued on Wednesday.Each student will receive an average of three yuan (47 cents) daily from the central budget, said a statement issued after a State Council meeting presided over by Premier Wen Jiabao.The policy will be implemented on a trial basis in 680 less-developed counties, the statement said.Authorities will have to allocate a total of 16 billion yuan annually from the central budget to meet the policy's requirements, it said.The money will be given to schools instead of directly to the students' families, allowing the schools to provide more and better food in their canteens, the statement said.Efforts will be made to build better canteens in rural primary and middle schools, the statement said.The statement added that daily allowances for needy students at primary boarding schools will also be increased from three to four yuan, while those for students at middle boarding schools will rise from four to five yuan.

UNITED NATIONS, Oct. 28 (Xinhua) -- China's progress in meeting a development goal on children's health can serve as an inspiration to other countries working towards the same objective, Dr. Renee Van de Weerdt, chief of maternal, newborn and child health at the UN Children's Fund (UNICEF) told Xinhua in an interview Friday.Van de Weerdt said that "the example of China is very encouraging because it means it can be done, even in a very big country with a very big population."China is on track to meet the fourth Millennium Development Goal (MDG), one of the eight development targets that the international community has pledged to meet by 2015. MDG 4 requires that each country reduce its rate of mortality for children under age five to two-thirds of what it was in 1990.According to Van de Weerdt, most deaths of children under five take place in the first month of life. After the first month, the most prevalent causes of death are pneumonia and diarrhea.ACHIEVING THE GOAL WORLDWIDEThe international community has been doing "relatively well" in working towards achieving MDG 4, Van de Weerdt said.The UN Interagency Group for Child Mortality Estimation (IGME) stated in their 2011 Report on Levels and Trends in Child Mortality that the number of under-five deaths worldwide has dropped from more than 12 million in 1990 to 7.6 million in 2010."We really continue to see progress," Van de Weerdt said. "The number of children that die every year continues to drop so we are really pleased to see that progress. Unfortunately, the progress isn't sufficient to really be able to say that if we continue at this pace we would achieve MDG 4 by 2015."Some regions, according to Van de Weerdt, like Latin America and parts of Asia are making more headway towards the goal than others that are currently lagging behind.
