What is Body Mass Index?
Body Mass Index provides a definition for physicians in the selection of therapy for people who are overweight. One is clinically severe obese (morbidly obese) when he or she is so heavy that the fat tissue load creates other medical problems. Individuals who are morbidly obese are typically 100lbs in excess of ideal body weight. Body Mass Index is calculated by weight (kg) / height (meters squared).
Risk factors for related health conditions:
- Family history
- Current cigarette smoking
- Sedentary lifestyle/physical inactivity
- Waist-to-hip ratio
An increased waist-to-hip ratio or waist circumference is associated with increased risk for obesity-related health conditions. If the ratio in males is greater than 1, and in females is greater than .8 that qualifies as a risk factor. Or, if the waist circumference for males is greater than 40 inches and for females greater than 35 inches, it’s a risk factor.
