【社会人文】病态肥胖人群增加迅速
Number of morbidly obese growing rapidly
Study finds 3 percent of Americans are 100 pounds or more overweight
WASHINGTON - People who are 100 pounds or more overweight are the fastest-growing group of overweight people in the United States, researchers reported on Monday.
They found the proportion of the severely obese was 50 percent higher in 2005 than it had been in 2000 — a startling rate of growth.
“The proportion of people at the high end of the weight scale continues to increase at a brisk rate despite increased public attention on the risks of obesity and the increased use of drastic weight loss strategies such as bariatric surgery,” said Roland Sturm, an economist at Rand Corporation, a nonprofit research institute.
“The explosion in the use of bariatric (weight-loss) surgery has made no noticeable dent in the trend of morbid obesity,” Sturm added in a statement.
The researchers found that based on self-reported height and weight, which tends to underestimate the weight part, 3 percent of Americans are already severely obese — defined as having a body mass index of 40 or higher.
Body mass index is calculated by dividing weight in kilograms by the square of a person’s height in meters.
The researchers, whose report will be published later this year in the journal Public Health, found that the proportion of Americans with a BMI of 30 or more increased by 24 percent between 2000 and 2005.
The proportion of people with a BMI of 40 or more increased by 50 percent and the proportion of Americans with a BMI of 50 or more increased by 75 percent.
The number of bariatric procedures, which include stomach stapling and stomach bypass surgery, rose to an estimated 200,000 in 2006 from 13,000 in 1998.

More than 30 percent of Americans are overweight, with a BMI between 25 and 29, and another 30 percent on top of that are obese, defined as having a BMI of 30 or above.
Overweight people have higher risks of heart disease, diabetes and some cancer, and obesity makes the risks much more imminent. 本人已认领该文编译，48小时后若未提交译文，请其他战友自由认领 本人已认领该文编译，48小时后若未提交译文，请其他战友自由认领。 Number of morbidly obese growing rapidly
病态肥胖人群增加迅速
Study finds 3 percent of Americans are 100 pounds or more overweight
研究发现3%的美国人重达100磅（1磅=0.4536公斤）或更重
WASHINGTON - People who are 100 pounds or more overweight are the fastest-growing group of overweight people in the United States, researchers reported on Monday.
华盛顿-研究者本周一报道，美国体重达100磅或更重的人群在超重群体中剧增。
They found the proportion of the severely obese was 50 percent higher in 2005 than it had been in 2000 — a startling rate of growth.
研究者发现2005年重度肥胖人群比例比2000高50%，增长速度之快令人咋舌。
“The proportion of people at the high end of the weight scale continues to increase at a brisk rate despite increased public attention on the risks of obesity and the increased use of drastic weight loss strategies such as bariatric surgery,” said Roland Sturm, an economist at Rand Corporation, a nonprofit research institute.
Rand公司（一个非赢利性研究机构）的经济学家Roland Sturm说：“尽管公众日益重视肥胖带来的危害并采取更强有力的减肥措施如抽脂手术，但体重超过磅秤最大范围的人群所占的比例仍急剧增长。”
“The explosion in the use of bariatric (weight-loss) surgery has made no noticeable dent in the trend of morbid obesity,” Sturm added in a statement.
Sturm又称：“抽脂手术应用的增加使人们不太关注病态肥胖增加的趋势。”
The researchers found that based on self-reported height and weight, which tends to underestimate the weight part, 3 percent of Americans are already severely obese — defined as having a body mass index of 40 or higher.
研究者发现基于自报的身高和体重得出的数据（偏于低估了体重部分），已有3%的美国人患有严重肥胖-这项指标的指数一般定义在40及以上。
Body mass index is calculated by dividing weight in kilograms by the square of a person’s height in meters.
体重指数的计算方法是体重（公斤）除以身高（米）的平方。
The researchers, whose report will be published later this year in the journal Public Health, found that the proportion of Americans with a BMI of 30 or more increased by 24 percent between 2000 and 2005.
研究者发现体重指数达30或更高的美国人比例在2000年到2005年间增加了24%，此部分报道将于今年晚些时候发表在公众健康杂志上。
