The lean body mass (LBM) has been described as an index superior to total body weight for prescribing proper levels of medications and for assessing metabolic disorders, as body fat is less relevant for metabolism. ![]() Instead, the body fat percentage, which is the complement, is computed, and is typically 10–40%. The percentage of total body mass that is lean is usually not quoted – it would typically be 60–90%. Lean body weight (LBW) - is a component of body composition, calculated by subtracting body fat weight from total body weight: total body weight is lean plus fat. A value of 0.091 corresponds to the doubling of the relative hazard rate. The finding of the paper is that the BSI above 0.083 (when expressed in metric units) is indicative of a higher relative hazard. The inclusion of the latter is believed to make the BSI a better indicator of the health risks from excess weight than the standard Body Mass Index. Wikipediaīody shape index (BSI) - is a metric for assessing the health implications of a given human body height, mass and waist circumference. However, there is some debate about where on the BMI scale the dividing lines between categories should be placed. The BMI is an attempt to quantify the amount of tissue mass (muscle, fat, and bone) in an individual, and then categorize that person as underweight, normal weight, overweight, or obese based on that value. The BMI may also be determined using a table or 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 BMI is defined as the body mass divided by the square of the body height, and is universally expressed in units of kg/m2, resulting from mass in kilograms and height in metres. Wikipediaīody mass index (BMI) - is a value derived from the mass (weight) and height of an individual. The trend to personalized medicine is one approach to counter this weakness. It is also thought to be a distorting factor in Phase I and II trials that may result in potentially helpful medications being prematurely rejected. This can lead to significant overdosing and underdosing (and increased risk of disease recurrence). Typically there is a 4–10 fold variation in drug clearance between individuals due to differing the activity of drug elimination processes related to genetic and environmental factors. ![]() Nevertheless, there have been several important critiques of the use of BSA in determining the dosage of medications with a narrow therapeutic index, such as chemotherapy. ![]() For many clinical purposes BSA is a better indicator of Kouro than body weight because it is less affected by abnormal adipose mass. IBW (kg) = 45 (kg) + 2.3 (kg) × (Height (cm) × 2.54 - 60)īody surface area (BSA) - in physiology and medicine, the body surface area is the measured or calculated surface area of a human body.
