双标记水方法的发展使得有可能测试用于测量能量摄入的膳食摄入仪器的有效性。测量的能量消耗与能量摄入量的比较，无论是称重或估计的饮食记录对能量消耗表明，肥胖的主题，女性耐力运动员，和青少年低估了习惯和实际的能量摄入。个别低估50%并不罕见。即使在非肥胖的成年人中，偏差最小，能量摄入的个体误差的标准差也接近20%。对自我报告的饮食记录用于测量饮食摄入量变化的有效性的两项调查也表明，对实际变化的估计被大大低估了。由于偏差和不精确性，自我报告的能量摄入量应谨慎解释，除非在实验设计中包括评估其有效性的独立方法。版权所有（C）1995由W.B.桑德斯公司
Development of the doubly-labeled water method has made it possible to test the validity of dietary intake instruments for the measurement of energy intake. Comparisons of measured energy expenditure with energy intake from either weighed or estimated dietary records against energy expenditure have indicated that obese subjects, female endurance athletes, and adolescents underestimate habitual and actual energy intake. Individual underestimates of 50% are not uncommon. Even in non-obese adults, where bias is minimal, the standard deviation for individual errors in energy intake approaches 20%. Two investigations of the validity of self-reported dietary records for measuring change in dietary intake also indicate large underestimates of the actual change. Because of bias and imprecision, self-reported energy intakes should be interpreted with caution unless independent methods of assessing their validity are included in the experimental design.
