Dr. Cathal McCrory:

The figure of 50% of obese children becoming obese adolescents and 80% of obese adolescents becoming obese adults were not taken from Growing Up in Ireland study. They are based on a meta-analysis of 200,000 children across a series of countries and cohorts. It shows the importance of tackling this issue early. I would tackle it much earlier than even the programmes in question which are great interventions for primary schoolchildren.
