Table 5 shows selected results from five logistic regression models (three based on the 2001-2006 NHANES and two based on the 2001-2006 NHIS) used to predict the odds of having ever been diagnosed with diabetes, based on the BMI measures. All five multivariate logistic regression models include an identical set of covariates: gender, age, education, race/ethnicity and household income. From the odds ratios associated with the BMI measures (both in linear and quadratic form), it is apparent that the adjusted self-reported measures deliver risk estimates that are close to those obtained on the basis of the measured BMI scores. In particular, the estimates obtained from the adjusted NHIS data are almost identical in size to those for the BMI scores based on measured height and weight in the NHANES.
