      1. BMI >30 (Or >27 if other risk factors present)
    4. Very High Risk (Class 2 Obesity)
      1. BMI >35 (Or >30 if other risk factors present)

    1. Cardiovascular Disease: Nurses' Health Study
      1. Studied 115,818 nurses ages 30-55
      2. Over 14 years of study, 1292 nurses developed CAD
      3. Relative Risk (RR) of CAD increased with BMI
        1. Body Mass Index (BMI) < 21: RR = 1
        2. Body Mass Index (BMI) < 23: RR = 1.2
        3. Body Mass Index (BMI) < 25: RR = 1.48
        4. Body Mass Index (BMI) < 29: RR = 2.08
        5. Body Mass Index (BMI) > 29: RR = 3.53

Obesity (C0028754)

Definition (MEDLINEPLUS)

Obesity means having too much body fat. It is different from being overweight, which means weighing too much. The weight may come from muscle, bone, fat, and/or body water. Both terms mean that a person's weight is greater than what's considered healthy for his or her height.

Obesity occurs over time when you eat more calories than you use. The balance between calories-in and calories-out differs for each person. Factors that might affect your weight include your genetic makeup, overeating, eating high-fat foods, and not being physically active.

Being obese increases your risk of diabetes, heart disease, stroke, arthritis, and some cancers. If you are obese, losing even 5 to 10 percent of your weight can delay or prevent some of these diseases. For example, that means losing 10 to 20 pounds if you weigh 200 pounds.

Definition (NCI_NCI-GLOSS) A condition marked by an abnormally high, unhealthy amount of body fat.
Definition (NCI_CTCAE) A disorder characterized by having a high amount of body fat.
Definition (NCI) Having a high amount of body fat (body mass index [BMI] of 30 or more).
Definition (CSP) excessively high accumulation of body fat or adipose tissue in relation to lean body mass; the amount of body fat (or adiposity) includes concern for both the distribution of fat throughout the body and the size of the adipose tissue deposits; individuals are usually at high clinical risk because of excess amount of body fat (BMI greater than 30).
Definition (MSH) A status with BODY WEIGHT that is grossly above the acceptable or desirable weight, usually due to accumulation of excess FATS in the body. The standards may vary with age, sex, genetic or cultural background. In the BODY MASS INDEX, a BMI greater than 30.0 kg/m2 is considered obese, and a BMI greater than 40.0 kg/m2 is considered morbidly obese (MORBID OBESITY).
