BMI is a number calculated from a person’s weight and height. BMI provides a fairly reliable indicator of body fatness for most people and is used to screen for weight categories that may lead to health problems.
What is a BMI used for?
BMI is a reliable indicator of body fatness for most people. It is used to screen for weight categories that may lead to health problems. This calculator provides BMI and the corresponding weight category. Use this calculator for adults, 20 years old and older.
What does BMI tell you about your health?
BMI is a way to figure out your approximate level of body fat in an easy, inexpensive way. It’s a number based on your weight and height that can help you tell if you are at a healthy weight for your height. In general, the higher the number, the more body fat a person has.
What are the strengths and limitations of using BMI as a measure?
The strengths include the fact that BMI is cheap and relatively easy to use. The weaknesses include the fact that BMI percentiles are not widely used, and categorization of BMI percentiles may not adequately define risk of comorbid conditions.
What are limitations of BMI?
Factors such as age, sex, ethnicity, and muscle mass can influence the relationship between BMI and body fat. Also, BMI does not distinguish between excess fat, muscle, or bone mass, nor does it provide any indication of the distribution of fat among individuals.
What was the purpose of BMI when first introduced?
The BMI was introduced in the early 19th century by a Belgian named Lambert Adolphe Jacques Quetelet. He was a mathematician, not a physician. He produced the formula to give a quick and easy way to measure the degree of obesity of the general population to assist the government in allocating resources.
Should we still use BMI?
As a single measure, BMI is clearly not a perfect measure of health. But it’s still a useful starting point for important conditions that become more likely when a person is overweight or obese.
Does BMI tell the whole story?
doesn’t tell the whole story, experts say. NYT: Calculated by dividing one’s weight in kilograms by the square of one’s height in meters, body mass index, or B.M.I., doesn’t differentiate between fatty and lean tissue.
Is a BMI of 20.98 good?
BMI under 18.5: Underweight. BMI from 18.5 to 24.9: Normal weight. BMI from 25 to 29.5: Overweight.
What does BMI tell a doctor or physician?
Shortcomings of BMI
BMI is a screening tool that tells doctors whether someone is carrying excess body fat. But it doesn’t tell you anything about your body composition. That’s an important distinction. For one thing, athletes with low body fat but a high muscle mass tend to have higher BMIs.
What are some pros and cons of using the BMI as an assessment tool?
Body Mass Index Advantages and Disadvantages
- Advantages: Accurate Measurements Across a Group.
- Disadvantage: BMI Misses Normal Weight Obesity.
- Disadvantages: BMI Overestimates Risk for Some.
- Take a Holistic Approach to Measurements.
What is the advantage of using a BMI chart quizlet?
– BMI provides useful information about risks for various diseases and is used in many epidemiological and clinical studies. – BMI correlates with the incidence of cardiovascular complications (hypertension and stroke).
What are some drawbacks of using BMI in regards to body composition?
Body Mass Index’ biggest flaw is that it does not take into account the person’s body fat versus muscle (lean tissue) content. Muscle weighs more than fat (it is denser, a cubic inch of muscle weighs more than a cubic inch of fat).
How do Epidemiologists use BMI?
Body mass index (BMI) is typically used to define overweight and obesity in epidemiological studies. However, BMI has low sensitivity and there is a large inter-individual variability in the percent body fat for any given BMI value, partly attributed to age, sex, and ethnicity.
What is the limitation of using BMI to assess obesity?
One limitation to the body mass index is that it does not differentiate between fat and lean body mass. For example, an athlete or bodybuilder with a large amount of muscle mass could very easily fall into the overweight or obese categories based on their BMI.
Why is BMI a widely used tool in public health for measuring overweight and obesity?
Why is BMI used to measure overweight and obesity? Because calculation requires only height and weight, BMI is an inexpensive and easy tool.
