2.3. ABOUT BMI - BODY MASS INDEX
-
A study by American researchers from Harvard University found
that if BMI increases during the first 6 months, the child is more li-
kely to suffer from premature obesity at 3 years
. BMI is an indicator
4
of being overweight and potential medical risks, based on the ratio
of weight to height. The weight graph helps to identify children
who are obese or at risk of becoming so. BMI increases in the first
year and then decreases until the age of 6 before increasing again.
This rise, which occurs on average at 6 years, is called adiposity re-
bound
. The earlier the adiposity rebound takes place, the greater
5
the risk of obesity. An upward percentile crossing is a warning sign.

2.4. CALCULATING BMI IN CHILDREN
The child's BMI is calculated using the following formula: BMI =
weight (in kilograms) / (height (in meters) x height (in meters)). For
e
example, for a 9-year-old girl weighing 42 lb / 19 kg and measuring
43 in / 1.10 m, the BMI will be: BMI = 19 / (1.1 x 1.1) or 19 / 1.21 =
15.70. As you can see, the resulting BMI for the child in question
(15.70) is entirely in line with the BMI-for-age chart for girls.
