Abstract:
Introduction:Introduction: obesity is associated with high levels of oxidative stress (OS) and inflammation. There is a lot of evidence that some polyphenols, such as green tea, have a positive impact on the OS state and consecutively, on inflammation. Objectives: the purposes of this study were: a) evaluate OS biomarkers in both obese and normal weight women; and b) evaluate if green tea supplementation has an impact on OS and inflammatory cytokine biomarkers of obese women. Methods: we evaluated obese (body mass index [BMI] ≥ 40 kg/m²) and normal weight (BMI between 18.5 and 24.9 kg/m²) women. Blood samples were used to access malondialdehyde (MDA), trolox equivalent antioxidant capacity (TEAC) and inflammatory cytokines. We randomly chose obese patients (18 individuals) and then gave them green tea supplementation for eight weeks. Statistical analysis included the Shapiro-Wilk, Wilcoxon, independent and paired t tests; p < 0.05 were considered as significant. Results: we enrolled 42 obese (BMI: 48.2 ± 9.3kg/m2) and 21 normal weight (BMI: 22.5 ± 2 kg/m2) women with an average age of 36.2 ± 9.1 years old. The serum levels of MDA were higher in obese (2.52 ± 0.31 µmol/l) than in eutrophic women (2.13 ± 0.26 µmol/l; p = 0.000). On the other hand, lower TEAC values were observed in the obese (0.75 ± 0.06 mM/l) than in the eutrophic group (0.78 ± 0.04 mM/l; p = 0.009). After the green tea intervention, MDA decreased 4.7% and TEAC increased 10%. Interleukin-6 (IL-6) serum levels decreased 12.7% after treatment (p = 0.03). Conclusions: a) the obese group had lower antioxidant capacity than eutrophic; and b) green tea supplementation ameliorated TEAC and MDA and reduced serum levels of IL-6 in obese women. Introducción:Introducción: la obesidad se asocia con altos niveles de estrés oxidativo (EO) e inflamación. Existe mucha evidencia de que algunos polifenoles, como el té verde, tienen un impacto positivo en el estado del EO y, consecutivamente, en la inflamación. Objetivos: los propósitos de este estudio fueron: a) evaluar los biomarcadores de EO en mujeres obesas y de peso normal; y b) evaluar si la suplementación con té verde tiene un impacto en el EO y biomarcadores de citoquinas inflamatorias de las mujeres obesas. Métodos: evaluamos mujeres obesas (índice de masa corporal [IMC] ≥ 40 kg/m²) y con peso normal (IMC entre 18,5 y 24,9 kg/m²). Se utilizaron muestras de sangre para determinar el malondialdehído (MDA), la capacidad antioxidante equivalente de trolox (TEAC) y las citoquinas inflamatorias. Elegimos al azar pacientes obesas (18 individuos) y luego les dimos suplementos de té verde durante ocho semanas. El análisis estadístico incluyó las pruebas de Shapiro-Wilk, Wilcoxon, t pareadas e independientes; p < 0,05 fueron considerados como significativos. Resultados: se reclutaron 42 mujeres obesas (IMC: 48,2 ± 9,3 kg/m2) y 21 de peso normal (IMC: 22,5 ± 2 kg/m2) con un promedio de edad de 36,2 ± 9,1 años. Los niveles séricos de MDA fueron más altos en las personas obesas (2,52 ± 0,31 µmol/L) que en las mujeres eutróficas (2,13 ± 0,26 µmol/L; p = 0,000). Por otro lado, se observaron valores TEAC más bajos en los obesos (0,75 ± 0,06 mM/L) que en el grupo eutrófico (0,78 ± 0,04 mM/L; p = 0,009). Después de la intervención con té verde, la MDA disminuyó 4.7% y el TEAC aumentó 10%. Los niveles séricos de interleucina-6 (IL-6) disminuyeron 12.7% después del tratamiento (p = 0,03). Conclusiones: a) mujeres obesas tienen menor capacidad antioxidante que las eutrófica; y b) la suplementación con té verde mejora TEAC y MDA y redujo los niveles séricos de IL-6 en mujeres obesas.
