Question: Paragraph: But within the holding pattern there is a dramatic rise in "extreme" obesity among adults and children. The annual "F as in Fat" report from the Trust for America's Health and the Robert Wood Johnson Foundation found that the proportion of adults who are extremely obese - at least 100 pounds (45.4 kilograms) overweight - has climbed over the last three decades from 1.4 percent in the late 1970s to 6.3 percent in 2009-2010. That is about a 350 percent increase, researchers for the health nonprofit groups said. About 5 percent of children and teenagers are also now severely obese, they added. Rates of extreme obesity were nearly twice as high for women as for men, and were also particularly high for Hispanic boys and black girls. "As long as we continue to see those increases in extreme obesity, I think we need to be worried," Trust for America's Health Executive Director Jeffrey Levi told Reuters. Overall, the report found obesity rates stabilizing across the United States, though at historically high levels with nearly 36 percent of U.S. adults obese as of 2010. Only one state, Arkansas, had an increase in obesity levels. The findings follow this month's announcement that the obesity rate among low-income children between the ages of 2 and 4 dropped slightly, after 30 years of increases. "After decades of bad news, we're finally seeing signs of progress," researchers for the two health groups wrote in Friday's report that said government efforts to encourage healthier diets and more exercise were paying off. "I'm delighted but not surprised," said Kelly Brownell, dean of Sanford School of Public Policy at Duke University. "The collective effect is having an impact and turning things around ... We've managed the plateau, we may remain there. We will have to do more to achieve a downturn." The analysis, based on data from the Centers for Disease Control and Prevention, underscored America's continuing battle with weight. Obesity rates were highest in the South and Midwest in states including Louisiana, Mississippi and Oklahoma. In addition to geographic differences, rates were higher for people with less education and lower incomes, it found. Rates for those ages 45 to 64, the bulk of the so-called Baby Boomer generation, were also a concern as their obesity rates were 30 percent or higher in 41 states. In Alabama and Louisiana, their rate reached 40 percent. Increasingly heavy men also narrowed the obesity gender gap. "Ten years ago, the obesity rate for women was significantly higher than the rate for men," 33.4 percent compared to 27.5 percent, researchers wrote. Now, their "rates are essentially the same" at nearly 36 percent, they said. Health experts agreed with the report's conclusion that various government programs making school lunches healthier, mandating calorie counts on menus, discouraging soda consumption, integrating physical activity into the daily life and other weight-conscious changes were adding up to widespread behavior changes. The report recommended strengthening such programs. It said food and beverage companies should market only their healthiest products to children, the nation's transportation plans should encourage walking and biking, and everyone should be able to buy healthy, affordable foods close to home. Obesity is commonly measured by body mass index (BMI), a measure of one's height to weight. A BMI score of 30 or more is defined as obese, while extreme obesity is a score of 40 or higher. A score of 25 to 29 is considered overweight. Claim: U.S. obesity leveling off, but at high rate: report.

Answer: Obesity levels among adults appear to be holding steady across the United States, adding to recent evidence that the growth rate for U.S. waistlines is slowing, according to an analysis released on Friday.

Question: Paragraph: Roughly half of Yellowstone's 4,600 bison are estimated to have been exposed to brucellosis, a bacterial infection that can sometimes cause cows and bison to miscarry. Worries that infected bison may endanger cattle in states such as Montana that border Yellowstone had prompted the powerful ranching lobby to endorse biobullets - absorbable projectiles packed with vaccine. They would cut disease rates among bison by as much as 35 percent over 30 years. The proposal was the latest decades-long efforts to ease conflicts between livestock interests and wildlife advocates over management of Yellowstone bison. Park officials said they decided against the remote vaccination program because of its $9 million price tag, questions about its effectiveness and the possible impact on the millions of visitors who flock to the park to view iconic Western wildlife like bison. The measure would have required shooting the animals once a year for three decades, raising questions about how increased human interaction could affect bison within the wild herd. "We have concerns about how that repeated contact might impact bison behavior and their visibility to park visitors," said Yellowstone spokesman Al Nash. Nash said there was no documented case of wild bison transmitting brucellosis to cattle, which he said signifies the success of existing measures designed to separate the park's herd from domestic livestock. Those practices include returning bison that leave the park, testing and vaccinating bison that leave Yellowstone, and slaughtering some infected animals. Errol Rice, executive vice president of the Montana Stockgrowers Association, said the threats posed by infected bison to Montana's brucellosis-free certification, which protects the market value of cattle, warranted using biobullets. He said the program would have lessened the public outcry that erupts when wandering bison are corralled and shipped to slaughterhouses. "The capture and removal of bison has been a challenging issue for the park and Montana. Remote vaccination would have helped alleviate the public relations burden we have to deal with when bison migrate out of Yellowstone," he said. Stephany Seay, spokeswoman for Buffalo Field Campaign, a bison advocacy group, applauded the park's decision not to shoot bison with vaccine. "It was a mismanagement scheme based on a livestock model. We don't vaccinate skunks against rabies or mosquitoes against West Nile virus," she said. Claim: Yellowstone managers reject vaccinating bison with biobullets.

Answer: Yellowstone National Park managers have rejected a plan to use air rifles to shoot the nation's last herd of purebred bison with so-called biobullets containing a vaccine against a cattle disease, in a decision that has riled the U.S. livestock industry.

Question: Paragraph: The alert urged Americans to seek medical help in the event they suffered any "unusual, unexplained physical symptoms or events, auditory or sensory phenomena, or other health concerns." The alert comes as a U.S. medical team is screening more Americans who work at the Guangzhou consulate. A previous case in Guangzhou, disclosed last month, prompted the tests. The incidents have raised fears the unexplained issues that started in Cuba in 2016 have expanded to other countries. China says it has uncovered no information that could point to a cause. The most recent evacuations followed medical testing that revealed they might have been affected. State Department spokeswoman Heather Nauert said "a number of individuals" had been brought to the U.S. but didn't say how many were affected or evacuated. Friday's alert called for people to be attentive of symptoms including "dizziness, headaches, tinnitus, fatigue, cognitive issues, visual problems, ear complaints and hearing loss, and difficulty sleeping." It urged them "not to attempt to locate the source of any unidentified auditory sensation. Instead, move to a different location." The U.S. government has deemed the Cuba incidents "specific attacks" on American workers but hasn't publicly identified a cause or culprit. Most of the incidents were accompanied by bizarre, unexplained sounds that initially led U.S. investigators to suspect a sonic attack. Asked about the latest incidents, Chinese Foreign Ministry spokeswoman Hua Chunying said Thursday that the U.S. had not formally raised the matter with Beijing. "If the U.S. makes formal contact with us, China will continue necessary investigations in an earnest and responsible manner and maintain close communication and cooperation with the U.S.," Hua said at a regularly scheduled news conference. China earlier said it had looked into the case announced last month but came up with no clues about the cause of the symptoms. A U.S. official, who wasn't authorized to discuss the situation publicly and requested anonymity, said the evacuated American government workers were being brought from China for testing to the University of Pennsylvania. That's where doctors have been treating and studying patients previously evacuated from the U.S. Embassy in Havana. The preliminary findings of the medical reports on the 24 personnel affected in Cuba showed they had sensory and memory problems similar to the brain dysfunction seen with concussions. The Penn team said the patients from Cuba experienced persistent disability though rehabilitation therapy customized for them seemed to help. Canada in April also ordered families of diplomatic staff in Cuba to return home after mysterious health symptoms were detected in 10 Canadians stationed on the island. Canada said the 10 continued to show unexplained brain symptoms and that "medical information raised concerns for a new type of a possible acquired brain injury." In testimony before the Senate Foreign Relations Committee last month about the first case in China, U.S. Secretary of State Mike Pompeo said China had "said all the right things and have demonstrated their willingness to help us identify the vector which led to this medical incident." The China incidents affect one of the most important of the seven U.S. diplomatic outposts in the country. The Guangzhou consulate opened months after the establishment of diplomatic relations between Beijing and Washington in 1979 and moved to its new purpose-built facility in 2013. It serves four southern provinces with a combined population of more than 204 million and processes more than 1 million visa applications of all types annually. It is also the only U.S. diplomatic installation in China authorized to process immigrant visas and handle adoptions. People working in The Canton Place complex, a few kilometers (miles) from the consulate, said Thursday they were just hearing about the incidents, reflecting a lack of coverage in China's entirely state-controlled media. Aled Williams, a British teacher at a kindergarten said Thursday that the reports sounded "sci-fi-ish." "Hard to get my head around how it works," he said. "Better watch myself." Linda Chen, who runs a coffee shop in the area, said she was mystified as to why only certain people seemed to have been affected in an area known for its comfort and safety. "For me I feel it's very strange. But I don't feel that there's something to be very afraid of because it's probably a very special case," Chen said. ___ Associated Press writer Josh Lederman in Washington, D.C. contributed to this report. Claim: US Embassy in China sends new alert for mystery health issue.

Answer:
The U.S. Embassy in China sent its second alert in two weeks Friday to its citizens over unexplained health issues that have prompted the evacuation of a number of U.S. government employees working at a consulate in a southern city.
