In Reply: In response to Dr Main and colleagues, we provide a Table that shows the age-standardized prevalence of grade 2 obesity (BMI of 35-<40), grade 3 obesity (BMI of ≥40), and grades 2 and 3 obesity (BMI of ≥35) among adults over the survey periods covered by our article. There were no statistically significant increases over the period 1999 through 2008 in the prevalences of grade 2 or grade 3 obesity in sex-specific logistic regression models adjusted for age group and race/ethnic group.
