Under-and overreporting of energy intake in relation to body mass index (BMI, kg/m2) were examined by using 24-hour urinary sodium and potassium as biomarkers. The data were obtained from 2,124 men and 1,998 women aged 25-74 years who participated in the 1981-1984 Belgian Interuniversity Research on Nutrition and Health study conducted in Belgium. The ratios of dietary intake to urinary excretion of sodium and potassium, as a measure for relative underreporting, were inversely associated with BMI (for men, p=-0.019 for sodium ratio and bêta=-0.026 for potassium ratio ; for women, bêta=-0.017 for sodium ratio and bêta=-0.019 for potassium ratio ; all p1 as overreporters. The percentage of underreporters increased with increasing pooled sex-specific deciles of BMI (bêta=1.88, p
