Activity . If there is no Anthropometer or Stadiometer, how can you measure the height? Discuss it in class. BMI Calculation BMI is a simple mathematical calculation which helps us to find out if an individual is normal weighted, over weighted or obese.
BMI is calculated by dividing the weight of an individual by the square of the height which is expressed in kg/metre². World Health Organization (WHO) has recommended norms for categorising an individual as normal weighted, under weighted or over weighted. Table : BMI Calculation Category BMI (kg/m ) From To Very severely underweight - Severely underweight Underweight . Normal (healthy weight) .
Overweight . . Obesity and above BMI for children aged between to years is calculated in same way and with the same formula, but not judged on the basis of norms mentioned in the above table. Whatever the result comes after calculating the BMI is compared after preparing the percentile table of all the children falling under the same sex and age category.
Less then percentile is under-weight, to percentile is normal, to percentile is over-weight and above percentile is obese. Waist-to-hip ratio (WHR) The waist-to-hip ratio (WHR) helps us to find out the fat distribution by which we can help in evaluating the overall health of an individual. One who carries more weight around the middle than the hip may have higher risk of developing several health issues. This is the ratio of the circumference of the waist and the circumference of the hip of an individual.
This is calculated by dividing waist measurement with the hip measurement of an individual (W ÷ H). For example, if the measurement of the persons waist and hip is cm and cm respectively then his waist-hip ratio will be . . World Health Organisation (WHO) has recommended the given norms for WHR: Activity .
