What is obesity?

Obesity is an excessive increase in body fat in the body, to such an extent that it may have an influence on health.

ObésitéL'obésité is defined as exceeding the standard curves corpulence. These curves are expressed as percentiles, standard deviation, or standard deviations. The 50th percentile represents the median. Changes considered normal range from 10 to 90. Between the 90th and 97th percentile may have about overweight zone. Beyond 97, we talk about obesity.



New values

An international definition of childhood obesity based on BMI curves derived from different countries will soon be proposed. Two degrees of overweight will be defined by the percentile curves reaching values ​​of 25 and 30 to 18. This new international definition for child maintain continuity with the adult and will mainly compare the incidence of obesity in relation to the total population between different studies and between countries.

Changes with age
In the French baseline growth, where a reference population was followed longitudinally (over several years) from birth to 20 years, it has been observed that the majority of children 1 year did not stay in the same group of corpulence. In particular, 60% of fat kids in one year will no longer be in adulthood. Hence the importance for young children to focus on the dynamic aspect of the evolution of their body size and their adiposity rebound to identify children claiming support or preventive measures.
