  • Title: [Insulin resistance in childhood obesity].
    Author: Ilyés I, Mahunka I, Sári B.
    Journal: Orv Hetil; 1992 Aug 30; 133(35):2221-4. PubMed ID: 1528585.
    Abstract:
    Insulin binding to erythrocytes (IB) and serum immunoreactive insulin concentration (IRI) were measured and relationships between these parameters and body mass index (BMI) were investigated in obese children and age matched controls with normal body weight. IRI was increased and IB was decreased significantly in the obese group compared to data of the controls. The decreased IB was due to a decrease in insulin receptor number since it was not accompanied by alteration of half maximal inhibition dose (ID50). Strong negative correlations were found between BMI and IB and between IRI and IB while a positive association was seen between BMI and IRI. These results prove an interrelationship between weight excess, hyperinsulinism and insulin resistance in childhood obesity.
