Calculadora de índice de masa corporal (IMC)

BMI is body weight divided by a power of height, usually (height)2, which is said to be independent of stature. Calculations based on values for ideal body weight suggest that BMIs for normal men and women should be in the range of 18.5 to 25 kg/m2. Indeed, this range roughly corresponds to the 10th to 75th percentile values recorded from adult individuals. For infants and children, average BMI values change with age, from 13 kg/m2 at birth, to a peak of 18 at about 1 year, a nadir of 15 at about age 6 years, and then a rise to adult values during adolescence.

Individuals with high indices are classified as overweight, even obese, and those with subnormal indices as undernourished. However, such classifications cannot be applied, for example, to short muscular men or to tall asthenic women, and despite the sex difference in body fat, the average index is about the same for both sexes during the adolescent and young adult years.
