Clinically severe or morbid obesity (body mass index (BMI) >40 or 50 kg m(-2)) entails far more serious health consequences than moderate obesity for patients, and creates additional challenges for providers. The paper provides time trends for extreme weight categories (BMI >40 and >50 kg m(-2)) until 2010, using data from the Behavioral Risk Factor Surveillance System. Between 2000 and 2010, the prevalence of a BMI >40 kg m(-2) (type III obesity), calculated from self-reported height and weight, increased by 70%, whereas the prevalence of BMI >50 kg m(-2) increased even faster. Although the BMI rates at every point in time are higher among Hispanics and Blacks, there were no significant differences in trends between them and non-Hispanic Whites. The growth rate appears to have slowed down since 2005. Adjusting for self-report biases, we estimate that in 2010 15.5 million adult Americans or 6.6% of the population had an actual BMI >40 kg m(-2). The prevalence of clinically severe obesity continues to be increasing, although less rapidly in more recent years than prior to 2005.International Journal of Obesity advance online publication, 18 September 2012; doi:10.1038/ijo.2012.159.
