ABSTRACT

Objetivo: Relacionar los niveles séricos de adiponectina con el estado nutricional y resistencia a la insulina (RI) en adultos con o sin síndrome metabólico (SM), pertenecientes a la cohorte CDC de Canarias en Venezuela. Métodos: La muestra incluyó 62 adultos Canarios e hijos residentes en Venezuela. Se efectuó antropometría, determinación de presión arterial, análisis sérico de: glucosa, HDL-colesterol, triglicéridos, insulina y adiponectina. Resultados: La adiponectina fue significativamente inferior, comparado con los controles, en obesos, (2,16 ± 0,51 ng/ml vs. 2,62 ± 0,42 ng/ml, p =0,032) y sujetos con SM (1,85 ± 0,46 ng/ml vs. 2,55 ± 0,43 ng/ml, p =0,000). La adiponectina mostró una correlación inversa con edad, presión arterial diastólica así como con los indicadores de RI (HOMA, índice triglicéridos / HDL-colesterol y trigliceridemia). Conclusión: En la totalidad de la muestra, los sujetos mostraron hipoadiponectinemia, implicando alto riesgo cardiovascular, que podría explicarse parcialmente por la presencia de obesidad, SM, RI o relacionado con mayor edad que incrementa el riesgo de estrés oxidativo.


Objective: To relate serum adiponectin levels with nutritional status and insulin resistance (IR) in adults with and without metabolic syndrome (MS) cohort belonging to the CDC de Canarias en Venezuela. Methods: The sample included 62 people, Canaries and children living in Venezuela. Anthropometry, blood pressure determination, analysis of fasting serum glucose, HDL-cholesterol, triglycerides, insulin and adiponectin, were performed. Results: Serum levels of adiponectin were significantly lower in individuals with obesity (2.16 ± 0.51 vs 2.62 ± 0.42, p = 0.032) and subjects with MS (1.85 ± 0.46 vs 2.55 ± 0.43 p = 0.000), compared to respective control group. Pearson analysis showed an inverse correlation of adiponectin with age, diastolic blood pressure as well as indicators of insulin resistance (HOMA, index triglycerides, HDL-cholesterol and triglycerides). Conclusion: In the whole sample, the subjects showed low serum adiponectin, implying a high cardiovascular risk, which could be partially explained by the presence of obesity, MS, RI or related to older age that increases the risk of oxidative stress.
