Obese teens are at risk of becoming severely obese as adults, according to a new study.

根据一项新的研究,青少年肥胖者正处于成年后变得严重肥胖的风险中。

"What's unique about this study is, we are following them over 13 years," says researcher Penny Gordon-Larsen, PhD, associate professor of nutrition at the University of North Carolina, Chapel Hill.

“关于这项研究,独特的是我们随访了他们13年以上,” 查珀尔希尔北卡罗来纳大学营养学副教授研究员Penny Gordon-Larsen博士说。

She expected to see an increased risk of severe obesity during young adulthood in those teens who were obese, but the percentages were higher than she anticipated, she tells WebMD.

她期望看到青少年期肥胖的人们在成人早期增长的严重肥胖风险,但是比例比她期望的还要高,她告诉WebMD。

"Half of the obese female teens developed severe obesity by their 30s, and 37% of the obese male teens developed severe obesity," she says.

“一半的肥胖女性青少年在30岁前发展成严重肥胖症,并且37%的肥胖男性青少年发展为严重肥胖症,”她说。

Severe obesity is defined as having a body mass index (BMI) of 40 or greater. "When we are talking about severe obesity, we are talking about 80 to 100 pounds over normal body weight," Gordon-Larsen says.

严重肥胖被定义为体重指数为40或更大。“当我们谈论严重肥胖时,我们正在谈论超过正常体重80到100磅,” Gordon-Larsen说。

The excess weight carries with it an increased risk of health complications, such as high blood pressure, diabetes, asthma, and arthritis.

多余的重量带来伴随的健康并发症增长的风险,例如高血压、糖尿病、哮喘和关节炎。

The study is published in The Journal of the American Medical Association.

这项研究发表在《美国医学会杂志》上。

Tracking Obese Teens
While much research has shown that obesity and severe obesity have risen in recent years, there has been less research that looks at those who are obese early in life to see what happens as they enter young adulthood, Gordon-Larsen says.

追踪肥胖青少年
尽管很多研究已经显示肥胖和严重肥胖在近年已经升高,但是很少有研究观察生命早期肥胖的人们以搞清楚当他们进入成年早期时发生什么,Gordon-Larsen说。

She tracked 8,834 participants in the U.S. National Longitudinal Study of Adolescent Health, ages 12 to 21 when they entered the study in 1996. She followed them into adulthood, when they were ages 24 to 33 in 2007-2009.

她在美国国家青少年健康纵向研究中追踪了8834名参加者,当他们在1996年进入这个研究时年龄在12岁到21岁。她随访他们到成年时期,当他们在2007年-2009年中年龄是24岁到33岁。

Weight and height were measured during in-home surveys and body mass index was calculated. Participants came from 80 high schools and 52 middle schools and are representative of the U.S. population.

在家庭调查中,测量身高和体重,并且计算体重指数。参加者来自80个高等学校和52个中学,并且他们是美国人群的代表。

At the study's start in 1996, just 1% of the teens, or 79, were severely obese. Sixty of those, or 70.5%, remained severely obese in adulthood.

这项研究在1996年开始时,只有1%的青少年或79人是严重肥胖的。他们中60人或70.5%在成年时期仍是严重肥胖。

By 2009, 703 new cases of severe obesity -- or 7.9% of all the participants -- were found in those young adults who weren't severely obese as teens. Those 703 were more likely to have a higher BMI as a teen than those who didn't become severely obese as young adults.

到2009年,703名严重肥胖的新病例(或全部参加者的7.9%)在那些青少年时期不是严重肥胖的年轻成年中被发现。那703人在青少年时期比年轻成年时期不变的严重的肥胖的人们更易于有较高的体重指数。

Gordon-Larsen found gender and racial differences, with severe obesity rates highest among black women, with 52.4% of those who were obese as teens becoming severely obese at the study end.

Gordon-Larsen发现性别和种族差异,黑人女性中严重肥胖症最高,52.4%的青少年时期肥胖的那些人在研究结束时变得严重肥胖。

Put in other terms, overall, the obese teens were 16 times more likely to develop severe obesity as young adults compared to normal-weight or overweight (but not yet obese) teens, she found.

总体上,换句话说,与正常体重或体重超重(但是还不是肥胖)的青少年相比,肥胖的青少年在年轻人时发生严重肥胖症的可能要多16倍,她发现。

Less than 5% of those who were at a normal weight as teens became severely obese as young adults, she found.

青少年时期正常体重的人们中在年轻人时变得严重肥胖的低于5%,她发现。

Those who developed severe obesity gained about 80 pounds over the 13-year follow-up, Gordon-Larsen says. "I think these numbers are pretty staggering, in terms of the amount of weight gained and the risk," she says.

发生严重肥胖症的那些人在13年随访中增加大约80磅,Gordon-Larsen说。“我认为这些数字是相当令人震惊的,考虑到体重增加的数量和风险,”她说。

The study findings are no surprise to Jessica Rieder, MD, founder and director of the Bronx Nutrition and Fitness Initiative for Teens program, or B'N'Fit, for overweight and obese teens at Montefiore Medical Center in the Bronx, N.Y. She reviewed the study findings for WebMD.

该研究发现对Jessica Rieder医学博士是没有什么吃惊的,她是布朗克斯营养与青少年健康初步项目的创立者和主任,在纽约布朗克斯蒙蒂法沃医疗中心为了体重超重和肥胖青少年。她为WebMD评述了这个研究发现。

While programs to prevent childhood obesity have become more common, those to help youth already obese are less common, she says.
Gordon-Larsen tells parents of all children to "keep an eye on the weight gain."

尽管预防儿童期肥胖症项目已经变得十分普遍,帮助已经肥胖青年人的项目是非常少的,她说。
Gordon-Larsen告诉所有儿童的父母关注体重增加。

She suggests parents have a goal of ''keeping a healthy household." That means focusing on healthy food options and building physical activity into the day, encouraging kids to walk more and move more.

她建议父母们有一个保持健康家庭的目标。这意味着注重于健康饮食选择和白天进行体育活动,鼓励儿童多走和多动。

Rieder agrees, suggesting that healthy changes need to be adopted by all family members, not just children who are trying to maintain or lose weight. "As a family, you adopt a healthier lifestyle for everyone," she says. "The whole family does it together."

Rieder同意,建议全部家庭成员需要采纳健康改变,不只是儿童努力保持体重或减肥。“作为一个家庭,你为任何人采纳了一个更健康的生活方式,”她说。“整个家庭一起来进行它。”

Beyond those changes, Rieder says, ''the obese child needs a lot of support." She suggests parents of obese children and obese teens talk to their child's pediatrician and ask for screenings for diabetes, high cholesterol, and other potential problems. Ask what resources are available in the community to help your child lose weight.

Rieder说,在那些变化之外,“肥胖儿童需要大量的支持。”她建议肥胖儿童和肥胖青少年的父母们与他们孩子的儿科医生交谈,并要求筛查糖尿病、高胆固醇和其它潜在的疾病。询问在社区内可以得到什么资源来帮助你的孩子减肥。
