  • 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.

  • Keys explicitly judged BMI as appropriate for population studies and inappropriate for individual evaluation.

  • Arch Intern Med. The percentage of patients with congestive heart failure, myocardial infarction, and peripheral vascular disease was also highest in the obese groups.

  • In this paper, Keys argued that what he termed the BMI was " Keys explicitly judged BMI as appropriate for population studies and inappropriate for individual evaluation.

Ethnic variation

Conversely, when the Asia-Pacific cutoffs were applied, the percentage in the obese group linearly decreased wold the GOLD criteria increased in severity. The present study revealed that patients with COPD with a high BMI had better pulmonary function and health-related quality of life and fewer dyspnea symptoms. Appropriate Asian body mass indices? J Korean Med Sci. Obesity: preventing and managing the global epidemic.

Such a correlation between DLCO and obesity is controversial. Table 2 lists the baseline characteristics of the study participants. The mean BMI value was There had been two previous attempts to interpret the BMI cut-offs in Asian and Pacific populations 3,4which contributed to the growing debates.

The current WHO and NIH ranges of normal weights are proved to be associated with decreased risks of some diseases such as diabetes type II; however using the same range of BMI for men and women is considered arbitrary hea,th makes the definition of underweight quite unsuitable for men. June 17, According to mathematician Nick Trefethen"BMI divides the weight by too large a number for short people and too small a number for tall people. A new formula for computing Body Mass Index that accounts for the distortions of the traditional BMI formula for shorter and taller individuals has been proposed by Nick Trefethen, Professor of numerical analysis at the University of Oxford : [57].

International Journal of Epidemiology. Archived PDF from the original on So, if all body dimensions double, and mass scales naturally with the cube of the height, then BMI doubles instead of remaining the same. In this situation, BMI will increase without any corresponding increase in weight. Obesity Homepage in Japanese.

The BMI may be determined using a masss [a] world health organisation body mass index classification chart which displays BMI as a function of mass and height using contour lines or colours for different BMI categories, and which may use other units of measurement converted to metric units for the calculation. The health risks associated with increasing BMI are continuous and the interpretation of BMI gradings in relation to risk may differ for different populations. Waist circumference WC is a cheap and easy method of measurement. However, many taller people are not just "scaled up" short people but tend to have narrower frames in proportion to their height [ citation needed ]. June 17,

Body Mass Index BMI is a simple index of weight-for-height that is commonly used to classify underweight, overweight and obesity in adults. For example, the BMI of bodybuilder and eight-time Mr. Environment International. We have developed five key areas of policy that are a priority to us.

Due to lack of body composition data, evaluation of the association of clinical parameters such as lung function and diet score to FFMM was limited. BMIformerly called the Quetelet index, is a measure for indicating nutritional status in adults. History BMI is very easy to measure and calculate and is therefore the most commonly used tool to correlate risk of health problems with the weight at population level.

The BMI is generally used as a means of correlation between groups related by general mass and can serve world health organisation body mass index classification a vague means of estimating adiposity. Waist-to-hip circumference ratio has also been used, but has been found to be no better than waist circumference alone, and more complicated to measure.

Two BMI classifications were used to assess the clinical correlation between clinical parameters and BMI, and several differences were observed. Ann Am Thorac Soc. The BMI ranges are based on the effect excessive body fat has on disease and death and are reasonably well related to adiposity. It was developed by Adolphe Quetelet during the 19 th century.

A common use of the BMI is to assess how far an individual's body weight departs from what is normal or desirable for a person's height.

The Mantel—Haenszel chi-squared test was performed to determine the association between categorical variables.
