Interleucina-6 y resistina en relación con las medidas antropométricas en escolares / Interleukin-6 and resistin in relation to anthropometric measurements in school children

La prevalencia mundial de obesidad infantil ha aumentado considerablemente en las últimas tres décadas. La creciente incidencia en niños de trastornos como diabetes tipo 2, se cree es consecuencia de esta epidemia. Aunque los mecanismos exactos aún no están claros, la producción o secreción de adipocinas causadas por el exceso de tejido adiposo y su disfunción, pueden contribuir al desarrollo de enfermedades metabólicas relacionadas con la obesidad. El objetivo del estudio fue determinar en escolares las concentraciones séricas de interleucina-6 (IL-6) y resistina, y relacionarlas con las medidas antropométricas. Se estudiaron 103 escolares. La evaluación antropométrica incluyó peso, talla, pliegue tricipital (PTr), circunferencia de cintura (CC), índice cintura-talla (C/T) e índice de masa corporal (IMC). Las concentraciones de IL-6 y resistina fueron determinadas según el método ELISA. Los datos fueron analizados con el programa estadístico SPSS versión 20. Se consideró el 95% de confiabilidad estadística (p<0,05). La prevalencia de sobrepeso fue 15,54% y obesidad 11,65%. Los escolares con CC aumentada, índice C/T (sobrepeso/obeso) e IMC (sobrepeso) mostraron valores significativamente más elevados de IL-6. Solo los escolares con CC aumentada e índice C/T (sobrepeso/obeso) mostraron valores promedio más altos de resistina (p<0,05). La interleucina-6 mostró correlación positiva con CC (r=0,229;p=0,020) e índice cintura-talla (r=0,397;p<0,001); la resistina con el índice cintura-talla (r=0,283;p=0,004). Estos resultados sugieren que la CC y el índice cintura-talla son buenos indicadores antropométricos en escolares, pues su incremento se correlaciona de manera positiva con las citocinas proinflamatorias, vinculadas con el aumento del riesgo cardio-metabólico en la población infantil.

The worldwide prevalence of childhood obesity has increased greatly over the past three decades. The increasing occurrence in children of disorders, such as type 2 diabetes, is believed to be a consequence of this obesity epidemic. Although the precise mechanisms are still unclear, dysregulated production or secretion of adipokines caused by excess adipose tissue and adipose tissue dysfunction can contribute to the development of obesity-related metabolic diseases. The objective of the study was to determine the serum levels of interleukin-6 and resistin in relation to anthropometric measurements in school children. One hundred and three school-age children were studied. The anthropometric assessment included weight, height, triceps skinfold (TSF), waist circumference (WC), waist-to-height ratio (WHtR) and Body Mass Index (BMI). Interleukin-6 and resistin levels were measured by ELISA. The data were analyzed using the SPSS version 20 statistical program and 95% CIs (p<0.05) was considered significant. BMI values indicated that 15.54 % of the population was overweight, and 11.65 % was obese. We found that scholars with excess WC, WHtR and BMI (overweight) had higher levels of IL-6 and scholars with excess WC and WHtR had higher levels of resistin (p <0.05). Interleukin-6 showed positive correlation with WC (r=0.229; p = 0.020) and waist-to-height ratio (r=0.397; p<0.001); and resistin with waist-to-height ratio (r=0.283; p= 0.004). These results suggest that WC and waist-to-height ratio are good anthropometric indicators in school children, contributing to early detection and prognosis of metabolic risks in children, due to their positive correlation with pro-inflammatory cytokines (interleukin-6 and resistin).

Impact of the consumption of a rich diet in butter and it replacement for a rich diet in extra virgin olive oil on anthropometric, metabolic and lipid profile in postmenopausal women.

OBJECTIVE: To analyze the impact of the substitution of a rich diet in saturated fats with a rich diet in monounsaturated fats on anthropometric, metabolic and lipid profile in postmenopausal women. MATERIAL AND METHODS: A prospective, longitudinal and comparative study where 18 postmenopausal women participated in two periods of dietary intervention of 28 days each one: 1) (SAT diet) consumed butter. Caloric formula (CF) = 15% protein, 38% fat. [20% saturated fat (SFA), 12% monounsaturated fat (MUFA) and 47% carbohydrates and 6% polyunsaturated (PUFA)]. b) Period MONO: with extra virgin olive oil (EVOO). CF = 15% protein, 38% fat (<10% SFA, 22% PUFA and 6% MUFA) and 47% carbohydrates. Size and body composition, glucose, insulin, HOMA, TC, HDL-C, LDL-C, VLDL-C, TG, TC/HDL-C, LDL-C/HDL-C, TG/HDL-C and non-HDL-C/HDL.C were measured; dietary Anamnesis/24 hours, daily food record. ANOVA and Bonferroni statistical analysis (SPSS 20) was applied. RESULTS: The age was 56 ± 5 years, BMI 29.8 ± 3.1 kg/m2, waist circumference: 93.2 ± 10.1 cm, waist/hip ratio: 0.86 ± 0.14, waist/height: 0.59 ± 0.06 and 38.6 ± 4% body fat (NS). Lipid profile: SAT diet increased TC (p <0.001), LDL-C (p <0.002) and non HDL-Cholesterol (p <0.000), HDL-C increased in MONO diet (p <0.000). SAT diet: TC/HDL-c ratio, Non col HDL-c/HDL-c, LDL-c/HDL-c (p <0.000) and TG/HDL-c (p <0.000). In MONO diet decreased TC/HDL-c (p <0.015) and TG/HDL-c (p <0.016). CONCLUSIONS: The SAT diet increased cardiovascular risk, while the MONO diet decreased the risk to develop the metabolic syndrome components and choronary heart disease.
