Definitions of Obesity
A: How does one define when a person is considered to be obese and not just somewhat overweight? Height-weight tables give an approximate guideline as to whether one is simply overweight or has passed into the obese stage.
B: The World Health Organization recommends using a formula that takes into account a persons height and weight. The "Body Mass Index" (BMI) is calculated by dividing the persons weight in kilograms by the square of their height in meters, and is thus given in units of kg/m2. A BMI of 18.5-24.9 is considered to be the healthiest. A BMI of between 25 and 29.9 is considered to be overweight, while a BMI of over 30 is considered to be obese.
C: However, it is recognized that this definition is limited as it does not take into account such variables as age, gender and ethnic origin, the latter being important as different ethnic groups have very different fat distributions. Another shortcoming is that it is not applicable to certain very muscular people such as athletes and bodybuilders, who can also have artificially high BMIs. Agencies such as the National Cholesterol Education Program (NCEP) in the USA and the International Diabetes Foundation (IDF) are starting to define obesity in adults simply in terms of waist circumference.
Health Effects of Obesity
D: Over 2000 years ago, the Greek physician Hippocrates wrote that "persons who are naturally very fat are apt to die earlier than those who are slender". This observation remains very true today. Obesity has a major impact on a persons physical, social and emotional well-being. It increases the risk of developing diabetes mellitus type 2 ("mature onset diabetes") and also makes Type 2 diabetes more difficult to control. Thus weight loss improves the levels of blood glucose and blood fats, and reduces blood pressure. The association between obesity and coronary heart disease is also well-known.
Cancer
E: Furthermore, in 2001 medical researchers established a link between being overweight and certain forms of cancer, and estimated that nearly 10,000 Britons per year develop cancer as a result of being overweight. This figure was made up of 5,893 women and 3,220 men, with the strongest associations being with breast and colon cancers. However, it is thought that being overweight may also increase the risk of cancer in the reproductive organs for women and in the prostate gland for men.
F: The link between breast cancer and nutritional status is thought to be due to the steroid hormones oestrogen and progesterone, which are produced by the ovaries, and govern a womans menstrual cycle. Researchers have found that the more a woman eats, or the more sedentary her lifestyle, the higher are the concentrations of progesterone. This link could explain why women from less affluent countries have lower rates of breast cancer. Women from less affluent nations tend to eat less food and to lead lifestyles which involve more daily movement. This lowers their progesterone level, resulting in lower predisposition to breast cancer.
G: The Times newspaper, in 2002 reported that obesity was the main avoidable cause of cancer among non-smokers in the Western world!
Aging
H: Research published by St Thomas Hospital, London, UK in 2005 showed a correlation between body fat and aging, to the extent that being obese added 8.8 years to a womans biological age. The effect was exacerbated by smoking, and a non-overweight woman who smokes 20 cigarettes a day for 20 years added 7.4 years to their biological age. The combination of being obese and a smoker added at least ten years to a woman’s biological age, and although the study only involved women, the lead researcher Professor Tim Spector believes the finding would also apply to men.
I: The aging effect was determined by measuring the length of telomeres, tiny "caps" on the ends of chromosomes, which help protect the DNA from the ageing process. Indeed, telomeres have been dubbed the "chromosomal clock" because, as an organism ages, they become progressively shorter, and can be used to determine the age of the organism. Beyond a certain point, the telomere becomes so short that it is no longer able to prevent the DNA of the chromosome from falling apart. It is believed that excess body fat, and the chemicals present in tobacco smoke release free radicals which trigger inflammation. Inflammation causes the production of white blood cells which increases the rate of erosion of telomeres.
Dementia
J: Recent research (2005) conducted in the USA shows that obesity in middle age is linked to an increased risk of dementia, with obese people in their 40s being 74% more likely to develop dementia compared to those of normal weight. For those who are merely overweight, the lifetime risk of dementia risk was 35% higher.
K: Scientists from the Aging Research Centre at the Karolinska Institute in Sweden have been able to take information such as age, number of years in education, gender, body mass index, blood pressure level, physical activity and genetic factors, assigning each a risk score. They then used this information to devise a predictive test for dementia. This test will enable people at risk, for the first time, to be able to affect lifestyle changes which will reduce their risk of contracting dementia.
Other Problems
L: The world-wide upsurge in obesity, particularly in children, is of major economic concern, liable to drain economies. Of further concern is that research conducted in Australia and published in 2006, shows that up to one third of breech pregnancies were undetected by the traditional "palpation" examination, the danger being greatest for those women who are overweight or obese—a growing proportion of mothers. This means that such women are not getting the treatment required to turn the baby around in time for the birth, and in many cases require an emergency Caesarean section.
M: This is a true health-care crisis, far bigger than Severe Acute Respiratory Syndrome (SARS) and ultimately, even bigger than AIDS.
1. You can judge whether one is simply overweight or has passed into the obese stage according to the height-weight table.
2. Using the "Body Mass Index"to define a persons weight ideal is limited, because it does not takes into account many variables such as age, gender and ethnic origin.
3. A persons emotional well-being would be affected by obesity.
4. Obesity has something to do with cancer in the prostate gland for man.
5. Women from less affluent nations tend to have much less breast cancer.
6. A non-overweight woman who smokes 20 cigarettes a day for 20 years added 7.4 years to her biological age.
7. The excess body fat, like the chemicals present in tobacco smoke, can lead to inflammation.
8. Obese people in middle age run an increased risk of dementia .
9. The predictive test for dementia will help people to affect lifestyle changes that will reduce their risk of contracting dementia.

10 Ways Obama Could Fight Climate Change
[A] One of the biggest surprises of President Barack Obamas inaugural address,on Monday was how much he focused on fighting climate change, spending more time on that issue than any other. "We will respond to the threat of climate change, knowing that the failure to do so would betray our children and future generations," Obama said. The President pointed out that recent severe weather supplied an urgent impetus for energy innovation and staked the nations economic future on responding to a changing climate. "We cannot cede to other nations the technology that will power new jobs and new industries--we must claim its promise," Obama said. " Thats how we will maintain our economic vitality and our national treasure--our forests and waterways; our croplands and snowcapped (山顶积雪的) peaks. That is how we will preserve our planet, commanded to our care by God. " so what could the President reasonably do to deliver on that vow? Here are ten of their suggestions:
Sunset coal with new incentives and regulations.
[B] "Provide incentives to phase out the oldest, most polluting power plants," said Robert Jackson, a climate scientist at Duke University. Its already happening, to some degree, as more of the nation transitions to natural gas. Earth scientist Bill Chameides, dean of Dukes Nicholas School of the Environment and a former chief scientist at the Environmental Defense Fund, urges the administration to use its Clean, Air Act authority to promulgate (颁布 )carbon regulations for existing power plants like it has for new ones: "Doing that will force fuel switching from coal to natural gas. "Invest federal stimulus money in nuclear power.
[C] Its hardly a perfect fuel, as accidents like Japans Fukushima fallout have shown, but with safety precautions new nuclear plants can meaningfully offset dirtier types of energy, supporters say."Nuclear is the only short-to medium-term way to really get away from fossil fuels," said Peter Raven. President emeritus of the Missouri Botanical Garden. He said the damage done by relentless global warming will far exceed the damage done by faults in the nuclear system.
Kill the Keystone pipeline.
[D] The controversial Keystone XL oil pipeline is up for review again by the White House this year. "The font thing he should do to set the tone to a lower carbon economy is to reject the Keystone pipeline, “said Raymond Pierrehum Bert, a geophysical scientist at the University of Chicago. The pipeline was never going to be a major driver of global emissions, but Pierre humbert and some other environmentalists say that by killing it the President would send a clear message about Americas intent to ramp down fossil fuels.
Protect the oceans by executive order.
[E] Land use is complicated, but large swaths of oceans can be protected by executive order. Just as President George W. Bush designated the worlds largest marine monument northwest of Hawaii in 2006. Obama could single-handedly protect other areas. National Geographic Explorer-in-Residence Sylvia Earle said the President should focus on parts of the Arctic that are under U. S. control, putting them off limits to energy production, commercial fishing, and mineral exploration. Marine sanctuaries (禁捕区) wont stop climate change, but they can give marine species a better chance of adapting to it by reducing the other man-made threats the animals face.
Experiment with capturing carbon.
[F] Huge untapped reserves of natural gas and oil make it unlikely that the U. S. will transition away from fossil fuels in the immediate future. Instead, said Wallace Broecker, geology professor at Columbia Universitys Lamont-Doherty Earth Observatory, we should attack the atmospheres carbon surplus directly. "Obama could make available funds to build and test prototype air capture units" to capture and store CO2, said Broecker. Removing some carbon from the atmosphere could buy valuable time as policy makers and scientists explore more permanent solutions.
Grow government research for new energy sources.
[G] The Department of Energy has a nimble program thats tasked with innovative energy research—the Advanced Research Projects Agency-Energy. The ARPA-E funds research in biofuels, transmission,and battery storage, with an annual budget of $ 275 million. Last year, DOE officials requested at least $ 75 million more. Increasing funding for ARPA-E, said Rare Pomerance, former deputy assistant secretary of state for environment and development and currently an environmental consultant, "you get new technologies that undercut coal, oil, and gas. " Plus, he said, yon get a competitive advantage if American researchers uncover the next big idea in new energy.
Tax carbon.
[H] Congress would have to agree, but many climate experts say that the most meaningful way to tackle emissions is to set a price on carbon. "We should be asking people to pay the cost of putting carbon into the atmosphere as they buy the fuel," said Josh Willis, climate scientist and oceanographer at NASAs Jet Propulsion Laboratory. To gain political support for the idea, Obama would probably have to show that the tax wonld help accelerate technology, grow new industries, and pay down the deficit.
Dial back the federal governments energy use.
[I] With more than I. 8 million employees, $ 500 billion in annual purchasing power, and 500,000 buildings to operate, the federal government has been a leader in reducing energy use since Obama signed a 2009 executive order to cut waste. "I would urge him to keep using the power of government to promote energy conservation," said Syndonia Bret-Harte, an Arctic biologist who studies climate change at the University of Alaska, Fairbanks.
Build a scientific clearinghouse for climate information.
[J] "I advocate for building a better information system on what is happening and why," said Kevin Tren berth, head of the Climate Analysis Section at the U. S. National Center for Atmospheric Research. That involves compiling observations related to climate change from around the world and using the data to refine climate modeling. Think of it as a one-stop, user-friendly website that clearly demonstrates how weather data from around the globe are influenced by broader shifts in the planets climate.
Keep talking. Despite a consensus among top scientists, the world still needs some convincing on climate change.
[K] A CNN poll last week found that just 49 percent of Americans agree that global warming is real and is due to human activities. "The most important thing the President can do is to build on his inaugural comments to heighten the sense of urgency about rapid climate destabilization and clarify its connection to virtually every other issue on the national agenda," said David Orr, environmental studies professor at Oberlin College. That means using the bully clergymen to show how a more volatile climate affects everything from agriculture to transportation to 21st-century warfare.
46. The urge to promulgate carbon regulations is aimed at pushing power plants to replace coal by natural gas.
47. Marine sanctuaries should be preserved because they help sea species adapt to climate alteration.
48. The government should take the responsibility to raise Americans awareness about climate change.
49. Many climate experts believe that the most effective way to lower emission is to tax on carbon.
50. Nuclear supporters argue that nuclear system failures are less challenging than global warming.
51. Recent extreme weather made President Obama feel it is urgent to address climate change.
52. Keystone pipeline should be rejected because it is a signal to reduce fossil fuels.
53. Since Obama signed a 2009 executive order to cut waste, the federal government has taken the lead in saving energy.
54. Lower carbon emission will be most likely to happen if research in new energy resources succeeds.
55. Compared with turning to new energy, America prefers carbon capture and store as a temporary measure.
