It is also worth noting that the data presented in these maps rely on self-reported weight and height from the BRFSS. Because people tend to underreport their weight and overreport their height in telephone surveys, these figures are underestimates of the obesity prevalence in the US*. When measured height and weight data from the National Health and Nutrition Examination Survey are used, the prevalence of obesity in U.S. adults is about one-third greater than the prevalence reported in these surveys.
