What is bmi-for-age?
BMI-for-age, also known as the body weight index for age, is a concept that uses a standard calculation of body weight index, but in assessing that BMI takes into account the age of a person. The body changes as we age, so the amount of fat content is normal change as we age. In view of this, it is important when using BMI to determine whether a person is overweight or underweight. BMI has important consequences for adults because they age, but it is a term that is most common in discussion on child obesity issues.
The calculation of BMI of any person, whether adult or child, is relatively simple. The subject begins with measuring its height and weight. To calculate the BMI, the subject simply multiplies the weight in pounds by 703 and then distributes this value at the other. When using metric values for calculation BMI, the subject simply uses weight in kilograms and divides this number of meters height.
BMI-FOR-Age adjustment is particularly important when using BMI to evaluate the health of the child,Because children's bodies are subject to such substantial changes as they grow and develop. A healthy BMI for fully developed adults can be very different from a healthy BMI for a child. As a result, rather than following the standard BMI values, the BMI child evaluation is performed using a percentile system to determine whether the child can be overweight, underweight or obese.
Thesystem of the percentile system that BMI-for-age uses compares a BMI child with other children the same age groups. In general, when a BMI child is in or over 95. Percentile for its age group, it means that the child is overweight. When BMI is on or under the fifth percentile, then the child is underweight. When BMI is between 85 and 95. Percentile, this may indicate that Child is at risk of overweight.
BMI-for-age, however, is not only important in determining healthy BMI levels for children. The development of an adult body is not as extreme or as fast asHowever, the development of children but adult bodies are undergoing changes as they age. When men and women enter the middle -aged, they tend to see an increase in BMI. When they reach old age, BMI can drop, sometimes to an unhealthy level. To take into account these physical changes, it is important to use BMI-for-age values to determine the healthiest BMI levels for people of all age groups.
