　　科学美国人60秒中文翻译：

　　Obesity increases your risk for heart disease and stroke, diabetes, and even forms of cancer. 肥胖会使你罹患心脏病、中风、糖尿病甚至癌症的风险增加。

　　So it's probably a good idea to get in the habit of eating right and exercising while you're still young. 因此趁还年轻时养成正确饮食及锻炼身体的习惯是个不错的想法。

　　But teens get mixed messages about what's a healthy body weight. 但就何为健康的体重很多青少年都是一知半解。

　　They're bombarded with unrealistic images of ultra-skinny celebrities and models, 他们被那些不真实的骨瘦如柴明星及模特的图片狂轰滥炸，

　　while also seeing media coverage of obesity that includes photos of those who are exceptionally obese. 同时媒体对肥胖问题的报导也包括那些胖人的照片。

　　So a group of researchers in the U.K. wanted to know, do British teens have an accurate sense of where they fall along the weight scale? 因此英国的研究者们想要了解自己国家的青少年们对体重问题是否自始至终有一种确切的感受?

　　They examined data from nearly 5,000 13- to 15-year-olds collected between 2005 and 2012 by what's called the Health Survey for England. 研究人员对英格兰健康调查机构于2005至2012年收集的近5000名13-15岁青少年的数据进行了调查研究。

　　Of the group, nearly three-quarters were normal weight. 这群青少年中大约3/4呈现体重正常。

　　Twenty percent were overweight, with seven percent obese. 有20%的人超重，肥胖率为7%。

　　The survey included asked this question for that age group: 这项调查中会问及青少年们一个这样的问题：

　　Given your age and height, would you say that you are about the right weight, too heavy, or too light? 根据你的年龄和身高，你觉得自己是体重标准，超重还是太瘦呢?

　　Despite the thin-celebrity-saturated culture, 83 percent of normal weight adolescents thought they were, in fact, a healthy weight. 虽然当前受名人文化影响瘦为美，82%正常体重的青少年认为自己实际上是非常健康。

　　Not surprisingly, the data changed by gender, 11 percent of normal-weight girls thought they were too heavy, compared to just four percent of boys. 不奇怪的是，这些数据中存在性别差异，相比占4%的男孩，11%正常体重的女孩认为自己超重。

　　But the bad news: nearly forty percent of the overweight and obese teens did not self-identify as too heavy. 但坏消息是：将近40%的超重和肥胖青少年并不认为自己太重。

　　Overweight girls recognized the issue more than boys did—nearly half the boys did not think that they were too heavy. 相比男生，认识到这个问题的超重女孩的人数更多—而将近一半的男生并不认为自己的体重存在问题。

　　The study is in the International Journal of Obesity. 这项研究已经在《国际肥胖》期刊上发表。

　　The researchers say the data on overweight teens, particularly boys, may have implications for the future health and well being of young people, 研究人员表示尤其是男生，这些超重青少年的数据可能对年轻人未来的健康和幸福产生影响。

　　and that overweight teens are substantially more likely to become overweight adults. 而且这些超重的青少年很大可能在成年后依旧是超重。

　　Recognizing that there's a lack of awareness among some teens could be a first step toward a healthier future. 认识到这一点对于这些青少年而言是步入健康未来的关键一步。
