双语：肥胖青少年更易早尝禁果

Obese teens tend to be socially outcast, and so researchers had long assumed they were less likely to engage in the kinds of risky social behaviors that mark traditional adolescence: drinking, smoking and hooking up. But a new survey finds that in fact obese teens are just as likely to participate in these rites of teenhood as their thinner peers。

In some ways, obese teens' behavior is even riskier. The study found that obese teenagers drank alcohol about as often as normal-weight classmates, but they were more likely to smoke cigarettes. And while obese teen girls were less likely to have sex than thin girls, those who were sexually active were more likely to use drugs or alcohol before sex。

The survey included responses from 9,000 high school students. Among the students, 410 were extremely obese, and the rest were considered healthy weight。

"Obese adolescents are already at greater risk for the development of additional chronic health conditions, the likes of which may be exacerbated by cigarette smoking, resulting in compound health risk," wrote the researchers。

肥胖青少年常被社会排斥，研究人员也曾以为他们不像一般青少年那样，有较多冒险性质的社交行为，比如喝酒、吸烟、发生性关系。但最新调查发现，事实上，肥胖青少年与他们的苗条同伴一样，参加此类活动的次数并不少。

在某些方面，肥胖青少年的行为更加冒险。研究发现，他们和体重正常的同学喝酒频率不相上下，但是他们吸烟更多。尽管肥胖女孩子发生性关系的可能性要比苗条女孩子小，却不乏有积极活跃者在性交前吸食毒品或者饮酒。

该调查报告囊括了9000名高中生的反馈。其中410名为极度肥胖，剩下的则拥有健康体重。

“肥胖青少年已经成为慢性健康疾病的高发人群，吸烟可加重类似疾病，从而导致复合健康问题，”研究人员写道。
