The historical disparity values for men and women were -281 and -365 kilocalorie-per-day, (95% CI: -299, -264 and -378, -351), respectively. These results are indicative of significant under-reporting. The greatest mean disparity values were -716 kcal/day and -856 kcal/day for obese (i.e., ≥30 kg/m2) men and women, respectively.<h4>Conclusions</h4>Across the 39-year history of the NHANES, EI data on the majority of respondents (67.3% of women and 58.7% of men) were not physiologically plausible. Improvements in measurement protocols after NHANES II led to small decreases in underreporting, artifactual increases in rEI, but only trivial increases in validity in subsequent surveys. The confluence of these results and other methodological limitations suggest that the ability to estimate population trends in caloric intake and generate empirically supported public policy relevant to diet-health relationships from U.S. nutritional surveillance is extremely limited.Edward ArcherGregory A HandSteven N BlairPublic Library of Science (PLoS)articleMedicineRScienceQENPLoS ONE, Vol 8, Iss 10, p e76632 (2013)
