Relationship of weight to height Used to establish a ""healthy weight"" range is Body Mass Index assessment tool for the general population; Not appropriate to use with: Pregnant females and Overly trained athletes
Step-by-step explanation:
The body mass index measures the healthiness of a person by relating the height and weight of a person. It evaluates if a person has got a healthy weight for his/her height.
Based on the value obtained by using the height-weight BMI formula, a person is said to be either underweight, healthy weight, overweight or obese.
This is a great health marker or indicator which indicates the onset of any cardiovascular or metabolic diseases, etc.
BMI calculations may not be appropriate to be used for pregnant women or for overly trained athletes because their body weights are not constant and keeps changing with time. Hence any conclusion made from BMI calculations of these persons may not be interpreted correctly.
The weight of a pregnant woman increases with each trimester and the weight before and after pregnancy may vary.
Similarly, the weight of an overly trained athlete also will vary before and after training sessions.
