Obesity in children is on the rise and many countries have taken initial steps to prevent this epidemic. According to the theory of epigenetics the risk of obesity can be passed from one generation to the next, because of behavioural and/ or biological factors. Over the last years there has been more interest to explain the trans-generational diseases with the theory of epigenetics. Identifying an underlying cause for obesity is important but majority of the time it is the change in lifestyle.
Early diagnosis and the metabolic derangements associated with obesity have to be detected in a timely manner. The body fat mass is a better predictor of the metabolic derangement when compared to the BMI. Measurement of BMI is practical and cost effective in our set up.
Clinicians are encouraged to screen all children from 6 to 18 years old for obesity by making BMI measurements part of usual care. Physicians should also be talking with parents, many of whom do not realize when a child is obese and offer comprehensive, intensive behavioral interventions. The behavioural interventions are mainly life style modification and motivation.
