Insulin secretion in childhood obesity.


Journal Article (Academic article)

In 132 severely obese children (72 boys and 60 girls) who underwent institutional therapy, oral glucose tolerance tests were carried out on admission, and these children were divided into groups with normal and high insulin levels, in terms of the sigma IRI values obtained, on the basis of the reference value + 2SD calculated by Maruhama et al. From these children, those who had diabetes mellitus (DM) and those in whom DM was suspected were distinguished according to the diagnostic criteria of USPHS (Drash et al). The insulin levels were normal in 58 children and high in 64. Ten children were found to have DM, and 19 were suspected to have DM. Metabolism of the glucose load occurred at both normal and high insulin levels in some children. There was also a group of children in whom glucose metabolism was incomplete at high insulin levels and a group of children in whom glucose metabolism was not possible even at high insulin levels, showing an obvious DM reaction. These findings suggest that there is a difference in the sensitivity of the insulin receptors in these children. Age, severe obesity and a family history of DM were considered to be risk factors for DM. Although there was a moderate, positive correlation between sigma IRI and the obesity index and between sigma IRI and age, it seems that the level of insulin secretion varies considerably in obese children.
