Most published studies have failed to show a greater food intake in obese subjects than in nonobese. However, the sample sizes in most of these studies are small and the methodologies open to question. HANES I is based on a probability sample of 20,749 people, representative of the civilian noninstitutional population of the U.S. We analyzed a subsample of 6219 nonpregnant adults whose diet was not influenced by illness or drugs and who stated that their intake, estimated by dietary interview, represented their usual pattern. Neither the caloric intake nor the caloric intake adjusted for physical activity level and age was higher in the obese subjects. This suggests that, unless estimates of food intake differ in accuracy between obese and nonobese subjects, factors other than overeating should be given increased consideration in the etiology of obesity.
大多数已发表的研究未能表明肥胖受试者的食物摄入量高于非肥胖者。然而，这些研究中的大多数样本量较小，方法也存在问题。美国国家健康与营养检查调查（HANES I）基于对20749人的概率抽样，代表了美国非机构化的平民人口。我们分析了一个由6219名非怀孕成年人组成的子样本，他们的饮食不受疾病或药物影响，并且表示通过饮食访谈估计的摄入量代表了他们的日常模式。肥胖受试者的热量摄入量以及根据身体活动水平和年龄调整后的热量摄入量均不高于非肥胖者。这表明，除非肥胖和非肥胖受试者在食物摄入量估计的准确性上存在差异，否则在肥胖病因中应更多地考虑暴饮暴食以外的因素。
