Which of the following is true regarding body mass index (bmi)?

it is a poorer measure of body mass than height to weight tables.

it uses height, weight, and waist measurements in its calculations.

in population studies it is a good indicator of fat related health risks.

it is a good measurement for children and teens.

In population studies it is a good indicator of fat related health risks.

Explanation:

Various methods are used to assess the individual's body composition. Most of them, however, are not feasible for use in large population groups, mainly due to the high cost and difficulties of operationalization in field logistics.

With regard to anthropometric methods, skinfolds and bioimpedance are often used in the assessment of body composition, while the waist / hip ratio  and waist circumference  are used to assess abdominal concentration. of body fat and its relationship with chronic non-communicable diseases.

The body mass index (BMI), although not specific for the assessment of body composition, has been used to assess excess population weight and has gained relevance in epidemiological studies, both for the simplicity and easy obtaining of the measures that integrate its composition as well as enabling the classification of anthropometric status and monitoring of excess population weight.

Results of studies carried out with population groups have shown a high correlation between BMI and weight and the amount of body fat determined by direct measurements, such as waist circumference and waist / hip ratio, skinfolds and bioimpedance.

Thus, we can say that BMI in population studies is a good indicator of health risks related to fat.

it'll be alright, just keep on going and keep your head up!
