Both of these measurements must be used together to get a correct idea of your health risk. Here's how to assess your own risk:. Susan weighs lbs and is 5' 7" tall. First, find Susan's height in the first column-you will need to use 5'8". Now, look across that row to find Susan's weight lbs. Susan's BMI value falls in the lb range, which means that her BMI is between This falls in the "healthy weight" category. To get clear picture of Susan's overall risk, we need to measure her waist circumference - see below. Find your BMI classification and waist measurement on Table 2 below to see how these factors may influence your overall health risk. Her BMI value is classed as "healthy weight". By locating these two values on Table 2, we can see that Susan may be at increased health risk, based on her waist circumference and BMI value. While Susan's BMI alone is not linked to an increased health risk, her waist circumference shows that the amount of fat located around her waist may increase her risk of disease. Health Canada recommends that we try to lower our overall health risk by reaching and keeping a healthy body weight.

Similar to BMIs for adult weights, CDC has the four weight classifications associated with BMI-for-age for youth:. Underweight — Less than the 5th percentile BMI-for-age Healthy weight — Between the 5th up to the 85th percentile BMI-for-age Overweight — Between the 85th up to the 95th percentile BMI-for-age Obese — At or above the 95th percentile BMI-for-age.
