The state of obesity and obesity research.

摘要

CLASS II OBESITY (BODY MASS INDEX [BMI] >35) AND class HI obesity (BMI >40) is a prevalent condition that adversely affects health. According to the latest National Health and Nutrition Examination Survey (2007-2008), the prevalence of class II and III obesity was 14.3% of the US population 20 years or older.1 Women have a higher prevalence (17.8%) than men (10.7%) and non-Hispanic blacks have a higher prevalence (21.9%) than non-Hispanic whites (13.6%), with non-Hispanic black women having the highest prevalence reported (27.9%). Even though the overall rates of increase for obesity (proportion of the population with BMI >30) may have slowed in the last decade,1 the population distribution among men and women in the United States clearly indicates that class II and III obesity is a problem to be reckoned with, especially in women.
