Study Notes
Classifying Overweight and Obesity
- BMI (Body Mass Index) is a numerical value that reflects body weight adjusted for height
- Healthy BMIs range from 18.5 to 24.9
- Overweight adults have BMIs that range from 25.0 to 29.9; obese adults have BMIs that range from 30.0 to 39.9
- People whose BMIs are 40 or higher are classified as extremely obese
Excess Body Fat: Effects on Health
- People with BMIs greater than 25 have increased risks of type 2 diabetes, hypertension, and CVD
- Obesity is associated with a higher risk of certain cancers, including cancers of the gallbladder, pancreas, cervix, uterus, breast (postmenopausal women), colon, rectum, and kidney
- Obese patients have a high risk of experiencing serious complications during and after surgery
- Extremely obese individuals are far more likely to develop serious chronic diseases and die prematurely
Body Fat Distribution: Effects on Health
- Women tend to store extra subcutaneous fat below the waist, primarily in the buttocks and thighs ("pear shape"), which adds stress to hip and knee joints but is not associated with increased risk of serious chronic diseases
- Men tend to store extra visceral fat in the abdominal or central region of their bodies ("apple shape"), which is associated with higher risks of serious chronic diseases, especially CVD and type 2 diabetes
- Measuring waist circumference is an indicator of central-body obesity and can be used to determine risk of obesity-related disorders
- Central-body obesity is defined by a waist circumference of greater than 40 inches in men and greater than 35 inches in women
