About 1 million adult New Yorkers are obese(肥胖的), but nearly two-thirds of them don’t think they are, according to a study released on Tuesday by the city’s Department of Health and Mental Hygiene(卫生).
Among the obese, who account for about one in five New Yorkers, only 39% described themselves as “very overweight”, according to the report. 2% said they were very underweight, 1% said they were slightly underweight, 16% said they were just right and 42% said they were slightly over weight.
Some 2 million more New Yorkers are overweight, the report said, and one in five children in kindergarten is obese.
Only 44% of the city’s adults are at a healthy weight, and nearly 75% say they do not participate in(参加) any regular physical activity.
New York City’s adult obesity rate was 20% in 2003 compared with 23% nationwide in 2004.The national average has nearly doubled from 12% in 1993, the report said.
Overweight and obese are defined by body mass index, or BMI (=" kg/m)" , which is based on a person’s weight , adjusted(调整) for height, the department said.
Being obese means having a BMI of 30 or greater, while being overweight means a BMI of more than 25 but less than 30.
A 5-foot, 10-inch (1.78-meter) man weighing 175 pounds(79kg) would have a BMI of 25.1 and be considered overweight according to the department . If he weighed 210 pounds (95kg), he would have a BMI of 30.1 and be obese.
The report came from results of the department’s 2002 and 2003 yearly telephone surveys of some 10,000 adults.

Everyone makes mistakes in life, but for whales and dolphins, the “mistake” of landing on the shore costs the highest price---their lives.
People living along the coast of Australia and New Zealand have been shocked and saddened by the number of whales and dolphins that they have found on their beaches recently. Since November 28th, 96 whales and dolphins have died in Australia and 53 whales died in New Zealand. Although 20 whales were saved, some of these were not expected to live, as they were too weak to swim with the others back to sea.
Bob Brown, leader of Australia’s Green party, said the mass beaching was caused by the recent “sound bombing” of the ocean floor between the two countries. This is a method of testing for oil and gas reserves (储藏量).
But mass beaching of whales has long puzzled scientists. Typically most members of the stranded (搁浅) group will appear to be perfectly healthy. “Some researchers believe that close relationship within the group causes the problem, if one gets into trouble, the others will not leave” said Shery Gibney, a leading biologist in New Zealand. “Some will come in and try and assist it; if they get trapped on the beach, then more will come.”
Another common theory is that the whales’ navigation (导航) system are thought to break down in some way. It has been said that whales follow electromagnetic (电磁的) patterns in the sea-bed. The whales can get confused because these patterns sometimes change. That would be a bit like a new roundabout (环状交叉路) being built on a road you were used to driving on. You might be confused for a minute when you come to it for the first time, and you might even take a wrong turning before getting back on your route.
A different idea is that when whales chase fish for food they end up in shallow waters because they are not paying attention to where they are going.
And yet, from time to time a group will swim on purpose into shallow waters and end up on the beach, where they die. If returned to the sea, some whales often show great determination in restraining themselves.
