[Obesity and its relation with markers of inflammation and erythrocyte fatty acids in a group of overweight adolescents].

There is a general consensus that obesity is an eminently inflammatory process. This is justified by alterations observed in obese patients, which affect the secretion of certain cytokines such as ceruloplasmin, leptin, adiponectin, and interleukin-6 (IL-6), among others. In a parallel way, other research has also pointed out alterations in the composition of fatty acids in the erythrocyte membrane of overweight adults. The results obtained in our study confirm the existence of a significant correlation between the serum levels of some of the cytokines studied and the nutritional state of the sample studied. This means that for the population of children evaluated in our study, the serum concentrations of these biomolecules can be an important tool for the prediction of cardiovascular risk when they become adults. Furthermore significant differences were found regarding the composition of saturated fatty acids in the erythrocyte membrane.
