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.
