肥胖已成为我们这个时代讨论最多的问题之一。在2005年8月12日的互联网搜索中，“肥胖流行病”和“肥胖与健康”的点击率分别为753000和9680000。这些数字落后于“关系”的99 100 000次点击，但仍然令人印象深刻。Campos等人1关注的是肥胖作为一个公共卫生问题的强调是否有道理，或者它是否代表了没有得到当前数据很好支持的危言耸听的说法。首先要明确我们的立场，我们认为：（i）肥胖是一个公共卫生问题，（ii）肥胖对健康的危害被夸大了，肥胖作为一种健康风险的经验证据的力量与科学和非专业媒体对这个问题的关注程度和数量之间存在不匹配，（iii）大部分有关肥胖与健康结果的大型前瞻性研究，（如死亡率或非致命性疾病）不能充分解释这种关联的主要混淆因素-体力活动，及（iv）重点不应放在肥胖问题本身，而应放在饮食欠佳及缺乏运动上，因为这是导致肥胖的主要生活方式因素。这些主题将出现在整个报告中，因为我们对坎波斯等人讨论的四个主要观点进行了评论。
Obesity has become one of the most discussed issues of our time. An Internet search on August 12, 2005 yielded 753 000 hits for ‘obesity epidemic’and 9 680 000 hits on ‘obesity and health’. These numbers lag behind ‘relationships’ with 99 100 000 hits, but are impressive nonetheless. Campos et al. 1 focus on whether or not the emphasis on obesity as a public health problem is warranted or whether it represents alarmist claims that are not well supported by current data. To make our position clear at the outset, we believe that (i) obesity is a public health problem,(ii) the health hazards of obesity have been overstated and a mismatch exists between the strength of empirical evidence for obesity as a health risk and the intensity and amount of attention this issue receives in the scientific and lay press,(iii) most of the large prospective studies on obesity and health outcomes (eg mortality or non-fatal incident disease) fail to account adequately for a major confounder of this association—physical activity, and (iv) the focus should not be on obesity per se but on poor diet and physical inactivity, which are the principal lifestyle factors leading to obesity. These themes will appear throughout this report as we comment on each of the four major points discussed by Campos et al.
