Follow-up During the Peripubertal Period of Preterm Children Included in the Protocol Entitled "EPIPOD".

Follow-up During the Peripubertal Period of Preterm Children (Under 35 Weeks of Amenorrhea) Included in the "EPIPOD" Protocol : Evaluation of Insulin Resistance

Prematurity is associated with an increased risk of developing cardiovascular and metabolic disturbances in adulthood.

It has been demonstrated that the body composition of children born prematurely is different from that of children born under term with a deficit in fat free mass.

It can thus be wondered if this excessive adiposity does or does not predict the risk of insulin resistance in adulthood.

Children born prematurely, with a body composition measurement performed at discharge from neonatal hospitalization as part of the EPIPOD protocol, and now aged between 8 and 14 years, will be included in the INFANTPOD protocol.

Analysis of body composition, insulin resistance, renal function, pulse wave velocity, eating behaviour and of physical activity will be performed.

Inclusion Criteria:

• Children hospitalised at the Nantes University Hospital in the neonatal period
• With a body composition measurement performed at discharge from neonatal hospitalization as part of the EPIPOD protocol
• Born prematurely (under 35 weeks of amenorrhea)
• Included in the Lift cohort with follow-up up to 7 years
• Aged between 8 and 14 years at inclusion

Exclusion Criteria:

• Children with an isolated metabolic disease: insulin-dependent diabetes; endocrine disease (Cushing's, hypothyroidism)
• Age of 15 years or more
• with a chromosomal anomaly
• with contraindicating measurement of the BOP-POD: ventilatory support, continuous parenteral feeding, elimination stoma
• Refusal of either parent or child
