The best diagnosis of obesity is by methods simple and known worldwide, measuring in weight and height, according to the type of population that they belong. These indexes are used to value the degree and type of present obesity:
Body mass Index (BMI): It’s the relation of weight of the person in kilos divided by the height in meters; so an index BMI inferior to 25, it’s normal; between 25 and 30 is overweight; and major than 30 is obesity. It’s the main form of diagnose the obesity.
Presence of cutaneous folds: The folds measurement in the region bicipital, tricipital, subscapular, and suprailiac allow measuring and quantifying the fats of subcutaneous tissue.
YOU ARE OR YOU AREN’T OBESE, MEASURE YOUR
BODY MASS
Waist – hip index: It’s the relation of the perimeter of the waist of the person divided by the perimeter of the hip. This relation, when it’s major than 0.9 in women and major than 1.0 in men, is sign of obesity and signal of cardiovascular risk. The following table indicates us a relation between a normal person and the different types of obesity (waist and hip):
Normal person |
0.9 – 1.1 |
Person with risk of obesity |
1.1 – 1.2 |
Person with light obesity |
1.2 – 1.3 |
Person with moderate obesity |
1.3 – 1.5 |
Person with serious obesity |
1.5 – 1.7 |
Person with massive obesity |
1.7 – 2.0 |
Person with morbid obesity |
major than 2.0 |
Bioelectric impedanciometry: It’s another method to diagnose the obesity. They are quantified the compartments of total body water, lean mass, and fat mass.
Also you have to determine the volume of fat. This can be made measuring the thickness of a skin fold, between the two fingers (under the arm or over the hips), and the measurements over 2.5 cm indicate excess of body fat. Also you can measure of this way, first it’s weighed in ground, and then it’s immersed in water. A formula based on these two measurements shows the percentage of body fat.
