Some 1 million adult New Yorkers are obese, 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.
Among the obese, who account for about one in five New Yorkers, only 39 percent described themselves as "very overweight," according to the report.
Two percent said they were very underweight, 1 percent said they were slightly underweight, 16 percent said they were just right and 42 percent said they were slightly overweight.
About 2 million more New Yorkers are overweight, the report said, and one in five children in kindergarten is obese.
Only 44 percent of the city's adults are at a healthy weight, and nearly 75 percent say they do not participate in any regular physical activity.
New York City's adult obesity rate was 20 percent in 2003 compared with 23 percent nationwide in 2004. The national average has nearly doubled from 12 percent in 1993, the report said.
Overweight and obese are defined by body mass index, or BMI, which is based on a person's weight, adjusted 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 (79 kg) would have a BMI of 25.1 and be considered overweight, according to the department. If he weighed 210 pounds (95 kg), he would have a BMI of 30.1 and be obese.
The report was compiled from results of the department's 2002 and 2003 annual telephone surveys of some 10,000 adults.
调查：大部分纽约胖子对自身体重浑然不知
美国纽约市日前公布的一项调查报告显示，该市成年肥胖者约为100万人，占到纽约总人口五分之一左右，但在他们中有将近三分之二的人却并不认为自己是个胖子。
据路透社11月23日报道，美国纽约市公众健康及精神卫生管理部门于11月22日发布的一份调查报告显示，在这些肥胖人士中，只有39%的人将自己的体重状况描述为“严重超标”，有2%的人竟认为自己“很瘦”，而声称自己“微瘦”的人占1%，有16%的人表示自己的体重“正合适”，而多达42%的人宣称自己只是“稍胖了一点”。这项报告是在对大约1万名成年人进行电话调查后形成的。
这份报告划定胖人的标准是体重指数(BMI)，即将体重(kg)除以身高(m)的平方所得的数值。BMI值处于25到30之间即是所谓体重超标，而BMI值大于或等于30的话，就意味着此人是一个胖子。
报告还指出，约有200万纽约人处于体重超标的状态下。幼儿园的儿童中肥胖者所占比例为五分之一。只有44%的纽约成年人的体重符合健康标准，而有接近75%的人表示他们从不进行任何有规律的健身运动。
