Disparity of rEI and TEE for men and women (20–74 years).

*All estimates are weighted means.aSignificantly different from NHANES I at p≤0.001 (Women).bSignificantly different from NHANES I at p≤0.001 (Men).cSignificantly different from NHANES I at p≤0.05 (Men).dSignificantly different from NHANES I at p≤0.05 (Women).Note: TEE = estimated total energy expenditure; IOM = Institute of Medicine; rEI = reported energy intake; BMR = Basal Metabolic Rate calculated via Schofield predictive equation.These values were calculated by subtracting the IOM TEE from the NHANES rEI. Negative values indicate the kilocalorie-per-day (kcal/day) value of underreporting.
