To examine the distribution of patterns of macronutrient density in relation to obesity.
Cross sectional.
Denmark.
323 men and women aged 35-65 years, selected randomly from a larger population sample of Danish adults.
Bias in dietary reporting of energy and protein intake in relation to percentage body fat, assessed by comparison of data from an interview on dietary intake with data estimated from 24 hour nitrogen output, validated by administering p-aminobenzoic acid, and estimated 24 hour energy expenditure.
Degree of obesity was positively associated with underreporting of total energy and protein, whereas compared with total energy reported, protein was overreported by the obese subjects.
Errors in dietary reporting of protein seem to occur disproportionately with respect to total energy, suggesting a differential reporting pattern of different foods. Although, on average, all subjects showed a greater underreporting of energy than of protein, this was most common in the obese subjects. Snack-type foods may be preferentially forgotten when obese people omit food items in dietary reporting. These results seem to agree with the general assumption that obese people tend to underreport fatty foods and foods rich in carbohydrates rather than underreport their total dietary intake. These results may have implications for the interpretation of studies of diet and comorbidities related to obesity.
研究常量营养素密度模式与肥胖症之间的关系分布情况。
横断面研究。
丹麦。
从丹麦成年人的更大规模人群样本中随机选取的323名年龄在35至65岁之间的男性和女性。
通过比较饮食摄入量访谈数据与根据24小时氮排出量估算的数据（通过给予对氨基苯甲酸进行验证）以及估算的24小时能量消耗，评估能量和蛋白质摄入量的饮食报告偏差与体脂百分比的关系。
肥胖程度与总能量和蛋白质报告不足呈正相关，而与报告的总能量相比，肥胖受试者蛋白质报告过多。
蛋白质饮食报告中的误差似乎在总能量方面不成比例地出现，这表明不同食物的报告模式存在差异。尽管平均而言，所有受试者能量报告不足的情况都比蛋白质更严重，但这在肥胖受试者中最为常见。肥胖者在饮食报告中遗漏食物项目时，零食类食物可能会被优先遗忘。这些结果似乎与普遍的假设一致，即肥胖者倾向于少报高脂肪食物和富含碳水化合物的食物，而不是少报他们的总体饮食摄入量。这些结果可能对肥胖相关饮食和合并症研究的解释有影响。
