The incidence of diabetes in children, which is constantly increasing worldwide is estimated in mainland France at about 15/100 000 per year with a wide disparity between countries and a north gradient South.

In Reunion island, about 30 children a year seem to reveal diabetes before the age of 18 years but no precise data has ever been published on this subject.

Indeed, while type 1 diabetes (insulin-dependent autoimmune) represents historically the majority of cases of diabetes revealed at pediatric age (about 90%), since a little more than 10 years other types of diabetes seem emerge at pediatric age. This is particularly the case of type 2 diabetes in connection with the global epidemic of obesity.

The purpose of the investigator's study is the exhaustive prospective collection of all cases of diabetes revealed before the age of 18 in the Reunion region over a period of 5 years.
