and BRFSS estimates have exhibited similar secular trends and associations with health outcomes as those based on physical measurement.56, 58 The correlation between measured and self-reported BMI ranges from 0.89 to 0.97, 55,59 and correlation of reporting bias with sociodemographic variables is mitigated in these analyses by the inclusion of numerous socio-demographic covariates in multivariate models. As demonstrated in Supplemental Tables 1 and 2, the association between FH-Alc and self-report based obesity is consistent across socio-demographic categories. Considering all of these factors, the tendency for higher BMI individuals to underestimate their BMI to a larger degree, if independent of FH-Alc, could result in a slight underestimation of the true association between FH-Alc and obesity.
