Check your BMI (Body Mass Index) – Calculate it yourself

Assessment  of weight Related health Risks


Assessment of weight and health risk involves using three key measures:


  1. Body mass index (BMI)
  2. Waist circumference
  3. Risk factors for diseases and conditions associated with obesity

Body Mass Index (BMI)


BMI Chart

BMI is a useful measure of overweight and obesity. It is calculated from your height and weight. BMI is an estimate of body fat and a good gauge of your risk for diseases that can occur with more body fat. The higher you’re BMI, the higher your risk for certain diseases such as heart disease, high blood pressure, type 2 diabetes, gallstones, breathing problems, and certain cancers.


Although BMI can be used for most men and women, it does have some limits:


  • It may overestimate body fat in athletes and others who have a muscular build.
  • It may underestimate body fat in older persons and others who have lost muscle.

Waist Circumference


Measuring Waist Circumference helps screen for possible health risks that come with overweight and obesity. If most of your fat is around your waist rather than at your hips, you’re at a higher risk for heart disease and type 2 diabetes. This risk goes up with a waist size that is greater than 35 inches for women or greater than 40 inches for men. To correctly measure your waist, stand and place a tape measure around your middle, just above your hipbones. Measure your waist just after you breathe out.

How to Calculate BMI


Here is a Method for Calculating BMI. (Example:- Person 5 feet 7 inches tall, Weighing 184 lbs.)


1. Multiply weight (in pounds) by 703                 184 x 703 = 129,352


2. Divide the answer in step 1 by height (in inches)    129,352 /67 = 1,930


3. Divide the answer in step 2 by height (in inches) to get your BMI 1,930/67 = 28.8


BMI = 28.8

Normal 18.5–24.9


Overweight 25.0–29.9

Extreme Obesity >40.0–


Risk Factors of Overweight/Obese

Obesity Campaign Poster

For people who are considered Obese (BMI greater than or equal to 30) or those who are Overweight (BMI of 25 to 29.9) and have two or more risk factors, it is recommended that they should lose weight. Even a small weight loss (between 5 and 10 percent of your current weight) will help lower your risk of developing diseases associated with obesity. People who are overweight, do not have a high waist measurement, and have fewer than two risk factors may need to prevent further weight gain rather than lose weight.
