Morbid Obesity CV Risk
Objective

• To determine the prevalence of morbid obesity
  (weight gt300 pounds) and clustering of
  cardiovascular risk factors (diabetes mellitus,
  current smoking, hypertension, low HDL
  cholesterol, and elevated C-reactive protein)
  among participants in the United States National
  Health and Nutrition Examination Surveys (NHANES)

Study Population

• Male and female participants with body weight
  measures from NHANES II (1976-80), III (1988-94)
  and 1999-2004
• Patients stratified by weight lt300 or gt300 pounds
• Diabetes defined by self-report, physician
  diagnosis, fasting glucose gt126 mg/dL, or
  medication use

Conclusions

• Prevalence of morbid obesity (weight gt300 pounds)
  increased 15-fold between 1976-2004
• The prevalence of hypertension, diabetes
  mellitus, low HDL cholesterol, and elevated CRP
  is significantly higher in subjects gt300 compared
  with lt300 pounds
• Weight limits on radiologic equipment for
  cardiovascular imaging may preclude morbidly
  obese patients from undergoing diagnostic
  procedures
