of intervention.' Although the level of concern for
class I and class II obesity (BMI 30.0±39.9) is higher
and the likelihood of weight-related chronic conditions
is higher, the recommendations are similar,
including the emphasis on risk factor reduction
rather than on weight loss per se. However, for class
III obesity (BMI ^ 40.0), the WHO expert committee
recommends intensive action to reduce weight,
including considering options such as surgical treatment
for obesity. In the total US population, the
overall prevalence of class III obesity is low, but for
some groups, particularly middle-aged non-Hispanic
black women, the prevalence of class III obesity
approaches or exceeds 10%.
