  Adolphe Quetelet - Wikipedia, the free encyclopedia
Quetelet received a doctorate in mathematics in 1819 from the University of Ghent.
Quetelet was among the first who attempted to apply it to social science, planning what he called a "social physics".
Quetelet also founded several statistical journals and societies, and was especially interested in creating international cooperation among statisticians.

Quetelet was convinced that probability influenced the course of human affairs more so than earlier generations had and more so than his contemporaries did.
Quetelet had come to be known as the champion of a new science, dedicated to mapping the normal physical and moral characteristics.
Quetelet believed that if the investigator took care to ensure that they had obtained accurate measurements of individuals belonging to a particular race or nationality, it would be possible to determine any unknown physical or intellectual aspect of the population under investigation.

 Body mass index - Wikipedia, the free encyclopedia
Body mass index (BMI) or Quetelet Index is a statistical measure of the weight of a person scaled according to height.
It was invented between 1830 and 1850 by the Belgian polymath, Adolphe Quetelet during the course of developing "social physics".
The Body Mass Index is generally used as a means of correlation between groups related by general mass and can serve as a basic means of estimating adiposity.

Another unfortunate aspect of Quetelet's otherwise groundbreaking work was the manner in which it seemed to reinforce the racial stereotypes so common in nineteenth century thought (or even today).

Quetelet was born in Ghent, to a French father who had established himself there ten years earlier, and a Brabantine mother.
This "moral statistics" of Quetelet is the distant progenitor of the modern science of sociology.
Among the philosophical issues raised by Quetelet's theory of social regularity, and also by the contemporary writings of Buckle, are questions of individual free well, and, ultimately, of individual responsibility for crime.

 Quetelet (body mass) index: not an unbiased quotient
It is convenient to dispose of an index standardized for weight, as that would provide a convenient index of obesity.
The Quetelet index (in English: ‘body mass index’, BMI) is used worldwide to this end: body mass/height².
It is therefore not an ideal index to establish the association between obesity and lung function.

 Body mass index - A measure of chronic energy deficiency in adults
Recent reports have advocated that height may be particularly useful as an index of socioeconomic conditions in developing societies because populations which are poorly fed and subject to repeated infections rarely grow well in either childhood or adolescence and fail to achieve an adult stature which is commensurate with their full genetic potential (Gopalan, 1987).
Since these competing power type indices are purported to provide an index of "body bulk" or "energy reserves" and each has been used by different investigators, it is extremely important that their relative merits are examined critically.
Thus, this index is relatively independent of height and is less biased by height than W/H. Adolphe Quételet (1796-1876) wee a mathematician and statistician and Permanent Secretary of the Royal Observatory of Brussels.

The reciprocal of the ponderal index and ectomorphy with their cut points comprised a larger age range in children and adolescents and a wider and more central range in the university students, both for the reported (current) and desired weights.
index and the ectomorphy allow that, from the age of 5.5 years on, the same cut points of adults may be used regardless of the sex.
The cut points proposed for body mass index should be reviewed for an adult population, because, as observed in the database analyzed, this method indicated that 35% of the male university students were overweight and, therefore, would be at a higher risk for morbidity and mortality.

 What is BMI?
The index is thought to be a more accurate indicator of body fat content than the standard height-weight tables that have been in use for over 30 years.
Body Mass Index (BMI) is one of the most accurate ways to determine when extra pounds translate into health risks and is becoming the measurement of choice used by health care professionals and investigators.
The BMI is also called the Quetelet index and while it does not distinguish fat mass from lean or muscle mass, it is a very useful approximation to what one should weigh depending on height.

The body mass index (BMI) is a calculated number, used to compare and analyse the health effects of weight on human bodies of all heights.
It was developed by the Belgian polymath Adolphe Quetelet in the course of working out his system of "social physics", between 1830 and 1850 (and is therefore also known as the Quetelet Index).
The Index is primarily a statistical tool, designed for public health studies, which enables the investigation and comparison of any medical data set in which the height and weight of subjects were recorded, to determine whether obesity was a correlate in health outcomes.

The Belgian astronomer Quetelet observed in 1869 that, among adults of normal body build, weight was proportional to the square of height: in other words W/H² was constant.
This useful index is therefore called Quetelet's index (QI), but Keys and colleagues in 1972 made a similar observation, and named it body mass index (BMI).
However, for most clinical and epidemiological purposes, Quetelet's index provides a satisfactory measure of obesity in people who are not hypertrophied athletes (in which case it overestimates fatness) or old (in which case it underestimates fatness).

The median value of the perinatal background index (our cutoff between favourable and unfavourable) was 29 points for primiparous women and 28 points for multiparous women.
In multiparous women, the perinatal outcome index controlled for background was significantly better with planned home birth than with planned hospital birth (table 3).

Weight-for-age is a useful index of acute malnutrition for children 6 months to 7 years old.
Weight-for-height is a sensitive index of current nutritional status, reflecting weight in relation to other children of the same height and sex, and is independent of age for children one to ten years old.
Quetelet's index, which is weight in kilograms divided by height in meters-squared, is commonly used as a measure of body mass and is also referred to as body mass index (BMI).

A higher Quetelet index (weight in kilograms divided by the square of the height in meters) was positively associated with the occurrence of each category of coronary heart disease.
The current Quetelet index was a more important determinant of coronary risk than that at the age of 18; an intervening weight gain increased risk substantially.
Odds ratios were determined for three body mass index categories: 19.1-23, 23.1-27, and 27.1+, with a relative risk of 1 for body mass index less than or equal to 19.

 Lung function - Obesity, pregnancy and ethnic differences
In children and adolescents lung function is positively correlated to the Quetelet index (body mass index, BMI: body mass/ height²); this might be because a higher index reflects more muscle mass.
In boys there is no relationship between obesity and lung function, in girls an increased Quetelet index appears to be associated with somewhat ‘better’ lung function: the putative explanation is that fat deposition is central in boys, and peripheral in girls where it would not affect the lung (ref. 1).
However, the body mass index is a biased index of obesity, as it correlates positively with standing height

The Body Mass Index or BMI is a method of classifying whether an individual is overweight, underweight, obese or normal weight based only on their height and weight and is not gender specific.
The modern Body Mass Index or BMI calculation is based on the work of the Belgian mathematician, Lambert Adolphe Jacques Quételet who published a study of the average man in 1835 entitled "A Treatise on Man and the Development of His Faculties" ISBN 0820110612.

Biochemical analyses for percent free estradiol, percent estradiol bound to sex hormone-binding globulin (SHBG), total estradiol, estrone, and follicle-stimulating hormone were performed on sera that had been kept at -80 degrees C since sampling.
For increasing quartiles of free estradiol, defined as the fraction of estradiol that is not bound to proteins, the Quetelet index-adjusted ORs of breast cancer were 1.0, 1.4, 3.0, and 2.9 (P value for trend <.01).
When we considered the percent of estradiol bound to SHBG, the Quetelet index-adjusted ORs were 1.0, 0.70, 0.40, and 0.32 (P value for trend <.01), thus suggesting a strong protective effect.
