Objectives: The first objective of this study was to analyze the metabolic profile of the population to be studied. The second one was to ascertain whether there was a significant association between the nutritional status of the subjects and the serum level of C-reactive protein. Finally, the third objective was to discover whether there was a correlation between C-reactive protein serum levels and waist to hip ratio values.
Sample and methodology: The sample was composed of 1001 adolescents, 9-17 years of age, from 18 schools in the provinces of Granada and Almeria. Their nutritional status was determined by means of anthropometric evaluation. For the metabolic study, a blood sample was collected from each subject by venipuncture. An analysis was performed of C-reactive protein, basal glycemia, ceruloplasmin, glycated hemoglobin (HBA1c), basal insulin, serum levels of lipoprotein (a), and non-esterified fatty acids (NEFA).
Results: The biochemical study reflected a normal metabolic profile with serum levels of C-reactive protein, basal glycemia, ceruloplasmin, glycated hemoglobin, basal insulin, lipoprotein (a) and non-esterified fatty acids slightly higher in the male subjects. The results of our studied showed that there was a statistically significant association (p < 0.05; F = 3.701) between the nutritional status of the subjects and serum levels of C-reactive protein. A statistically significant association (F = 9.008; p < 0.005) was also found between serum levels of C-reactive protein and waist to hip ratio values.
Conclusions: The C-reactive protein associated either with nutritional status or the waist to hip ratio is an effective biochemical marker of cardiovascular risk among the population of adolescents in our study.
Resumen: Objetivos: Los objetivos de este estudio fueron analizar el perfil metabólico de la población de estudio. En segundo lugar, verificar una asociación significativa entre el estado nutricional de los sujetos y los niveles séricos de proteína-C reactiva. Por último, comprobar la existencia de una correlación entre los niveles séricos de proteína-C reactiva y los valores del índice de cintura-cadera. Muestra y metodología: Una población de 1001 adolescentes de entre 9 y 17 años de edad, pertenecientes a 18 centros educativos de las provincias de Granada y Almería. Se evaluó el estado nutricional de los alumnos mediante antropometría. Para el estudio metabólico, se practicó una extracción sanguínea mediante punción venosa a cada alumno, analizando proteína-C reactiva, glucemia basal, ceruloplasmina, hemoglobina glicosilada (HBA1c), insulina basal, niveles séricos de lipoproteína (a) y ácidos grasos de cadena larga (NEFA). Resultados: El estudio bioquímico evidenció un perfil metabólico normal, destacando niveles séricos de proteína-C reactiva, glucemia basal, ceruloplasmina, hemoglobina glicosilada, insulina basal, lipoproteína (a) y ácidos grasos libres ligeramente superiores en chicos. Se encontró una asociación estadísticamente significativa (p.
