a
Categorical variables are expressed as weighted column percentages (95% CI). Body mass index, waist circumference, and glycemic testing results are expressed as mean (95% CI).
b
These numbers represent the population size in millions among all U.S. adults.
c
Overweight and obesity status were determined based on a measured BMI of ≥25kg/m2 and ≥30kg/m2, respectively, for all racial and ethnic groups. Normal weight status was defined by a BMI <25kg/m2.
