Waist to hip ratio cut-off levels
Excess abdominal fat distribution is indicated by a WHR greater than 0.8 for women and 0.9 for men.
Due to the natural variation in body shape and composition between different ethnicities, the cut-off points for determining central obesity are slightly different. Ethnicities with a smaller build, such as Japanese and Chinese, may be at risk at a lower WHR. It is best to see your doctor to have a thorough examination that takes these factors into account.
If your WHR is greater than the cut-off levels, you should see a doctor. You are at risk for developing the following conditions:
- Diabetes: A high WHR is not the most reliable prediction of diabetes, but it does correlate with individuals who have diabetic levels of fasting blood glucose. A WHR over 0.96 for men and 0.83 for females is associated with an increased risk of developing diabetes. If these WHR values are coupled with a BMI over 25, the risk is even greater. Tests for diabetes should be carried out immediately, and at least every three years.
- Ischaemic stroke: An elevated WHR is associated with an increased risk of ischaemic stroke. A 1.6-fold greater risk has been determined for females with a WHR greater than 0.87, and a 2.3-fold greater risk for men with a WHR greater than 0.98.
- High blood pressure: A large WHR is associated with high blood pressure. Even if you have a BMI in the normal range, you will still have an increased risk of hypertension if your WHR is high.
- Reduced lung function: Poor lung function is significantly correlated to a WHR greater than 0.94±0.06. Reduced lung function causes difficulties in breathing and physical performance.
- Metabolic risk factors: A large WHR is associated with abnormal levels of uric acid, C-reactive protein, triglyerol, insulin, glucose and HDL cholesterol. These organic compounds are all associated with various medical conditions.
