2013年2月20日上午,哈佛大学公共卫生学院的大礼堂里聚集了200多人。一位组织者介绍说,召开这次会议的目的是向大家解释,一项关于体重与死亡率的最新研究为何是错误的。这项研究报告于2013年1月2日发表在《美国医学会杂志》上,综合分析了97项研究的结果,而参与这些研究的受试者达到288万人。美国国家卫生统计中心的流行病学家凯瑟琳·弗莱戈带领的课题组研究发现,按照国际通行的体重评价标准,超重人群比体重正常人群在同一时期内的死亡率可能要低6%。这一结果刚公布就掀起了轩然大波。同时,该结果也引起了一些公共健康专家的强烈质疑。哈佛大学的营养学家兼流行病学家沃尔特·威利在接受电台记者采访时说:“这项研究简直就是垃圾,不值得大家浪费时间去关注它。”并
On the morning of February 20, 2013, more than 200 people gathered in the auditorium of the Harvard School of Public Health. One organizer said that the purpose of the meeting was to explain to everyone why a recent study on weight and mortality was wrong. The research, published in the Journal of the American Medical Association on January 2, 2013, provides a comprehensive analysis of the results of 97 studies involving 2.88 million participants in these studies. The research team led by Catherine Fleck, an epidemiologist at the National Center for Health Statistics, found that overweight people in the overweight population may be 6% less likely to die during the same period than the normal weight population, according to internationally accepted weight measures. The result just announced it set off an uproar. At the same time, the results also raised strong doubts among public health experts. Walt Willy, a nutritionist and epidemiologist at Harvard University, told radio reporters: “This research is simply rubbish and it is not worth everyone’s time to focus on it.”
