BMI is a numerical value of your weight in relation to your height. A BMI between A BMI of less than To check your BMI, type your height and weight into the BMI calculator for adults from the National Institute of Health. To calculate your BMI manually, multiply your weight in pounds by , divide by your height in inches, then divide again by your height in inches. Waist circumference is the distance around your natural waist at the iliac crest, or hip bone. Some well-trained people with dense muscle mass may have a high BMI score but very little body fat. For them, the waist circumference, the skinfold thickness or more direct methods of measuring body fat may be more useful measurements than BMI.

Obesity: BMI calculators and charts	This makes it difficult to have set values for BMI cut-offs for young people. However, in adults who have stopped growing, an increase in BMI is usually caused by an increase in body fat. You can use the body mass index BMI calculator for adults to calculate your BMI, provided you know your:. If your BMI is:. For older Australians over the age of 70 years, general health status may be more important than being mildly overweight. At the population level, BMI is used to indicate level of risk for morbidity disease risk and mortality death rates. Differences in BMI between individual adults of the same age and sex are usually due to body fat, however there are many exceptions to this rule, which is why a BMI figure may not always be accurate. BMI calculations will overestimate the amount of body fat for:. However, BMI cannot differentiate between body fat and muscle mass. This means there are some exceptions to the BMI guidelines:. BMI calculations used for adults are not a suitable measure of weight for children or adolescents. The current BMI charts for children have been developed by the US Centres for Disease Control and Prevention. They are useful for the assessment of overweight and obesity in children aged over two years. To calculate a child's BMI, you can use the body mass index calculator for children and teenagers. However, BMI charts should be used only as a guide to indicate when to make small lifestyle changes, and when to seek further guidance from a doctor or a dietitian. The link between being overweight or obese and the chance you will become ill is not definite. Research is ongoing. Statistically, there is a greater chance of developing various diseases if you are overweight. When identifying health risk in adults, it is recommended that you combine your BMI classification with your waist circumference as a measurement of disease risk. Men, in particular, often deposit weight in the waist region and therefore have an increased risk of obesity-related disease. Studies have shown that the distribution of body fat is linked to an increased prevalence of diabetes, hypertension, high cholesterol and cardiovascular disease. Generally, the associations between health risks and body fat distribution are:. Generally, according to the CDC:. The same factors that limit the efficacy of BMI for adults can also apply to children and adolescents. Additionally, height and level of sexual maturation can influence BMI and body fat among children. BMI is a better indicator of excess body fat for obese children than it is for overweight children, whose BMI could be a result of increased levels of either fat or fat-free mass all body components except for fat, which includes water, organs, muscle, etc. In thin children, the difference in BMI can also be due to fat-free mass. Below are the equations used for calculating BMI in the International System of Units SI and the US customary system USC using a 5'10", pound individual as an example:. BMI prime is the ratio of a person's measured BMI to the upper limit of BMI that is considered "normal," by institutions such as the WHO and the CDC. Since BMI prime is a ratio of two BMI values, BMI prime is a dimensionless value. A person who has a BMI prime less than 0. The table below shows a person's weight classification based on their BMI prime:. BMI prime allows us to make a quick assessment of how much a person's BMI differs from the upper limit of BMI that is considered normal. It also allows for comparisons between groups of people who have different upper BMI limits. The Ponderal Index PI is similar to BMI in that it measures the leanness or corpulence of a person based on their height and weight. The main difference between the PI and BMI is the cubing rather than squaring of the height in the formula provided below. While BMI can be a useful tool when considering large populations, it is not reliable for determining leanness or corpulence in individuals. Although the PI suffers from similar considerations, the PI is more reliable for use with very tall or short individuals, while BMI tends to record uncharacteristically high or low body fat levels for those on the extreme ends of the height and weight spectrum. Below is the equation for computing the PI of an individual using USC, again using a 5'10", pound individual as an example:. Also, it's common for teens to gain weight quickly — and see their BMI go up — during puberty. Your doctor can help you figure out whether this weight gain is a normal part of development or whether it's something to be concerned about. It's important to look at BMI as a trend instead of focusing on individual numbers. Any one measurement, taken out of context, can give you the wrong impression of your growth. Our BMI calculator can help you find out what your BMI is. When you get your results, it's a good idea to ask a doctor or health professional to help you interpret the results. Although not a perfect measure of body fat, BMI can help identify teens who are gaining weight too slowly or too quickly. If you are concerned about your weight , talk to your doctor.

Adolphe Quetelet , a Belgian astronomer , mathematician, statistician , and sociologist , devised the basis of the BMI between and as he developed what he called "social physics". Instead, it was a component of his study of l'homme moyen , or the average man.

Quetelet thought of the average man as a social ideal, and developed the body mass index as a means of discovering the socially ideal human person. The modern term "body mass index" BMI for the ratio of human body weight to squared height was coined in a paper published in the July edition of the Journal of Chronic Diseases by Ancel Keys and others.

In this paper, Keys argued that what he termed the BMI was "if not fully satisfactory, at least as good as any other relative weight index as an indicator of relative obesity".

The interest in an index that measures body fat came with observed increasing obesity in prosperous Western societies. Keys explicitly judged BMI as appropriate for population studies and inappropriate for individual evaluation. Nevertheless, due to its simplicity, it has come to be widely used for preliminary diagnoses.

If pounds and feet are used, a conversion factor of 4. When the term BMI is used informally, the units are usually omitted. BMI provides a simple numeric measure of a person's thickness or thinness , allowing health professionals to discuss weight problems more objectively with their patients.

BMI was designed to be used as a simple means of classifying average sedentary physically inactive populations, with an average body composition. A common use of the BMI is to assess how far an individual's body weight departs from what is normal for a person's height.

The weight excess or deficiency may, in part, be accounted for by body fat adipose tissue although other factors such as muscularity also affect BMI significantly see discussion below and overweight. The WHO regards an adult BMI of less than BMI is used differently for people aged 2 to It is calculated in the same way as for adults but then compared to typical values for other children or youth of the same age.

Instead of comparison against fixed thresholds for underweight and overweight, the BMI is compared against the percentiles for children of the same sex and age. A BMI that is less than the 5th percentile is considered underweight and above the 95th percentile is considered obese.

Children with a BMI between the 85th and 95th percentile are considered to be overweight. Studies in Britain from have indicated that females between the ages 12 and 16 had a higher BMI than males of the same age by 1. These recommended distinctions along the linear scale may vary from time to time and country to country, making global, longitudinal surveys problematic.

The cut-off for observed risk varies based on populations and subpopulations in Europe, Asia and Africa. The Hospital Authority of Hong Kong recommends the use of the following BMI ranges: [19].

A study from the Japan Society for the Study of Obesity JASSO presents the following table of BMI categories: [20] [21] [22]. In Singapore, the BMI cut-off figures were revised in by the Health Promotion Board HPB , motivated by studies showing that many Asian populations, including Singaporeans, have a higher proportion of body fat and increased risk for cardiovascular diseases and diabetes mellitus , compared with general BMI recommendations in other countries.

The BMI cut-offs are presented with an emphasis on health risk rather than weight. In the UK, NICE guidance recommends prevention of type 2 diabetes should start at a BMI of 30 in White and New research based on a large sample of almost 1.

In , the U. National Institutes of Health brought U. This had the effect of redefining approximately 25 million Americans, previously healthy , to overweight.

This can partially explain the increase in the overweight diagnosis in the past 20 years [ when? By , National Health and Nutrition Examination Survey of showed that The BMI ranges are based on the relationship between body weight and disease and death.

The BMI is generally used as a means of correlation between groups related by general mass and can serve as a vague means of estimating adiposity.

The duality of the BMI is that, while it is easy to use as a general calculation, it is limited as to how accurate and pertinent the data obtained from it can be. Generally, the index is suitable for recognizing trends within sedentary or overweight individuals because there is a smaller margin of error.

This general correlation is particularly useful for consensus data regarding obesity or various other conditions because it can be used to build a semi-accurate representation from which a solution can be stipulated, or the RDA for a group can be calculated. Similarly, this is becoming more and more pertinent to the growth of children, since the majority of children are sedentary.

Smaller effects are seen in prospective cohort studies which lend to support active mobility as a means to prevent a further increase in BMI. In France, Italy, and Spain, legislation has been introduced banning the usage of fashion show models having a BMI below A study published by Journal of the American Medical Association JAMA in showed that overweight people had a death rate similar to normal weight people as defined by BMI, while underweight and obese people had a higher death rate.

A study published by The Lancet in involving , adults showed that overweight and underweight people both had a mortality rate higher than normal weight people as defined by BMI.

The optimal BMI was found to be in the range of High BMI is associated with type 2 diabetes only in people with high serum gamma-glutamyl transpeptidase. In an analysis of 40 studies involving , people, patients with coronary artery disease with normal BMIs were at higher risk of death from cardiovascular disease than people whose BMIs put them in the overweight range BMI 25— One study found that BMI had a good general correlation with body fat percentage, and noted that obesity has overtaken smoking as the world's number one cause of death.

A study that followed 11, subjects for up to eight years concluded that BMI is not the most appropriate measure for the risk of heart attack, stroke or death. A better measure was found to be the waist-to-height ratio.

The medical establishment [50] and statistical community [51] have both highlighted the limitations of BMI. Part of the statistical limitations of the BMI scale is the result of Quetelet's original sampling methods.

For women, and people of non-European origin, the scale is often biased. As noted by sociologist Sabrina Strings, the BMI is largely inaccurate for black people especially, disproportionately labelling them as overweight even for healthy individuals. The exponent in the denominator of the formula for BMI is arbitrary.

The BMI depends upon weight and the square of height. Since mass increases to the third power of linear dimensions, taller individuals with exactly the same body shape and relative composition have a larger BMI.

So, if all body dimensions double, and mass scales naturally with the cube of the height, then BMI doubles instead of remaining the same. This results in taller people having a reported BMI that is uncharacteristically high, compared to their actual body fat levels.

In comparison, the Ponderal index is based on the natural scaling of mass with the third power of the height. However, many taller people are not just "scaled up" short people but tend to have narrower frames in proportion to their height. tables are excellent for identifying obesity and body fat in large populations, but they are far less reliable for determining fatness in individuals.

For US adults, exponent estimates range from 1. In other words, people with small frames would be carrying more fat than optimal, but their BMI indicates that they are normal. Conversely, large framed or tall individuals may be quite healthy, with a fairly low body fat percentage , but be classified as overweight by BMI.

However, falling into one's ideal weight range for height and build is still not as accurate in determining health risk factors as waist-to-height ratio and actual body fat percentage. Accurate frame size calculators use several measurements wrist circumference, elbow width, neck circumference, and others to determine what category an individual falls into for a given height.

In this situation, BMI will increase without any corresponding increase in weight. Assumptions about the distribution between muscle mass and fat mass are inexact.

BMI generally overestimates adiposity on those with leaner body mass e. A study in June by Romero-Corral et al. In other words, the BMI will be mostly correct when determining a person to be obese, but can err quite frequently when determining a person not to be. Despite this undercounting of obesity by BMI, BMI values in the intermediate BMI range of 20—30 were found to be associated with a wide range of body fat percentages.

Body composition for athletes is often better calculated using measures of body fat, as determined by such techniques as skinfold measurements or underwater weighing and the limitations of manual measurement have also led to new, alternative methods to measure obesity, such as the body volume indicator.

It is not clear where on the BMI scale the threshold for overweight and obese should be set. Because of this, the standards have varied over the past few decades. Between and the U. Dietary Guidelines have defined overweight at a variety of levels ranging from a BMI of In the National Institutes of Health NIH consensus conference recommended that overweight BMI be set at a BMI of In , an NIH report concluded that a BMI over 25 is overweight and a BMI over 30 is obese.

This became the definitive guide for determining if someone is overweight. One study found that the vast majority of people labelled 'overweight' and 'obese' according to current definitions do not in fact face any meaningful increased risk for early death. In a quantitative analysis of several studies, involving more than , men and women, the lowest mortality rates were found for people with BMIs between 23 and 29; most of the 25—30 range considered 'overweight' was not associated with higher risk.

The corpulence index uses an exponent of 3 rather than 2. People who are underweight are also at increased risk of death, although this is thought to be mainly because of underlying disease processes that produce weight loss 9.

Note: BMI was calculated based on measured height and weight and excludes pregnant women BMI is calculated as follows: weight in kilograms divided by height in metres squared.

BMI is calculated the same way for both adults and children. The calculation is based on the following formulas:. With the metric system, the formula for BMI is weight in kilograms divided by height in meters squared. Because height is commonly measured in centimeters, divide height in centimeters by to obtain height in meters.

Calculate BMI by dividing weight in pounds lbs by height in inches in squared and multiplying by a conversion factor of For adults 20 years old and older, BMI is interpreted using standard weight status categories.

These categories are the same for men and women of all body types and ages. BMI is interpreted differently for children and teens, even though it is calculated using the same formula as adult BMI. The CDC BMI-for-age growth charts take into account these differences and visually show BMI as a percentile ranking.

These percentiles were determined using representative data of the US population of 2- to year-olds that was collected in various surveys from to Obesity among 2- to year-olds is defined as a BMI at or above the 95 th percentile of children of the same age and sex in this to reference population.

The correlation between the BMI and body fatness is fairly strong 1,2,3,7 , but even if two people have the same BMI, their level of body fatness may differ The accuracy of BMI as an indicator of body fatness also appears to be higher in persons with higher levels of BMI and body fatness While, a person with a very high BMI e.

According to the BMI weight status categories, anyone with a BMI between 25 and However, athletes may have a high BMI because of increased muscularity rather than increased body fatness. In general, a person who has a high BMI is likely to have body fatness and would be considered to be overweight or obese, but this may not apply to athletes.
