Parámetros hormonales e inflamatorios en un grupo de mujeres con sobrepeso/obesidad / Hormonal an inflammatory biomarkers in a group of overweight and obese women

Introducción y Objetivos: Recientemente se ha descubierto que la obesidad es una patología caracterizada por un estado crónico de inflamación leve. El objetivo de este estudio fue describir la situación hormonal e inflamatoria de un colectivo de mujeres con sobrepeso/obesidad. Pacientes y métodos: se incluyeron mujeres > 18 años, con IMC ≥ 25 < 40 kg/m2. Se recogieron datos ocio-sanitarios, presión arterial, parámetros antropométricos, de actividad física, estudio bioquímico, hormonal e inflamatorio para determinar la situación hormonal e inflamatoria de un colectivo de mujeres antes del inicio de un tratamiento para el control de peso corporal. Resultados: participaron 104 mujeres con edad media de 48,4 ± 9 años y un IMC de 29,8 ± 3,5 kg/m2. Un 48% de las mujeres estudiadas se encontraba en etapa de menopausia. Un 8,9% presentó hiperinsulinemia. El valor medio obtenido de grhelina fue 38,8 ± 33,6 pg/ml, no se encontró correlación entre sus concentraciones y las variables antropométricas y bioquímicas estudiadas. Los valores medios de PCR, leptina, adiponectina, resistina, IL 6, IL 10 y PAI 1 fueron 3,0 ± 2,7 mg/dl, 36,3 ± 19,5 ng/ml, 8,3 ± 4,5 μg/ml, 24,3 ± 23,2 ng/ml, 51,6 ± 93,6 pg/ml, 10,0 ± 34,2 pg/ml y 22,3 ± 30,6 ng/ml, respectivamente. Estas concentraciones correlacionaron significativamente con diferentes variables antropométricas y bioquímicas, sin embargo, estas correlaciones fueron débiles. Variables como la edad y presencia o no de menopausia o la práctica de actividad física de forma regular no influyeron en los valores medios obtenidos. Las pacientes con obesidad tuvieron valores medios significativamente más elevados que aquellas con sobrepeso, aunque sólo en el caso de la resistina y PAI 1. Conclusión: El grupo de mujeres estudiadas presentó cifras de adipoquinas alteradas en relación a otros estudios realizados en población con situación nutricional normal. Esto pone en evidencia la situación inflamatoria presente en estos pacientes y los valores obtenidos pueden contribuir a establecer unos rangos normalizados de estos marcadores para el colectivo de personas con sobrepeso y obesidad (AU)

Background and objectives: The aim of this study was to describe the hormonal and inflammatory status of a group of overweight/obese women. Patients and methods: The sample studied was a crosssectional cohort of women > 18 years of age, BMI ≥ 25 <40 kg/m2, prior to starting a weight control program. Data collected were: demographic characteristics, blood pressure, anthropometric parameters, physical activity data, and biochemical, hormonal and inflammatory biomarkers. Results: The study involved 104 women with a meanage of 48.4 ± 9 years and a BMI of 29.8 ± 3.5 kg/m2. Some 48% of the women studied were in menopause. Some8.9% had hyper insulinemia. The mean ghrelin value was38.8 ± 33.6 pg/ml; there was no correlation between ghrelinlevels and anthropometric and biochemical variables.CRP, leptin, adiponectin, resistin, IL6, IL10, and PAI1were 3.0 ± 2.7 mg/dl, 36.3 ± 19.5 ng/ml, 8.3 ± 4.5 mg/ml,24.3 ± 23.2 ng/ml, 51.6 ± 93.6 pg/ml, 10.0 ± 34.2 pg/ml and22.3 ± 30.6 ng/ml, respectively. Obese patients had significantly higher mean values of resistin and PAI 1 than those who were overweight. These levels correlated significantly with anthropometric and biochemical variables; however, the correlations were weak. Age, menopause or the regular practice of physical activity had no effect on mean values. Conclusions: The group of women studied had altered inflammatory biomarkers in relation to people of normal weight. The study shows the inflammatory status of overweight/obese individuals, and the values obtained may help to establish standard ranges for these markers (AU)

Assessment surveys conducted in La Paz University Hospital in Madrid during the 9th "National Nutrition Day 2010"]. / Análisis de las encuestas sobre etiquetado nutricional realizadas en el Hospital La Paz de Madrid durante la 9ª edición del "Día Nacional de la Nutrición (DNN) 2010".

INTRODUCTION: Nutrition labelling (NL) provides information on the energy and nutrients in a food and it represents a valuable tool to help consumers make informed decisions about their diet and lifestyle. However, little is known about how consumers perceive the nutrition labelling information. OBJECTIVES: Evaluate the knowledge of NL of a population survey and examine aspects such as attention, reading, understanding and utility. MATERIAL AND METHODS: 200 volunteers were interviewed about NL on National Nutrition Day (NND) on May 28, 2010 at the La Paz University Hospital in Madrid. The questionnaire was self-administered and this contained 10 closed multiple choice questions. RESULTS: The surveyed group (66.7% women and 33.3% men) had a mean age of 42.0 ± 15 years and a BMI of 24.1 ± 3.8 kg/m². A percentage of 86.5% had completed secondary and higher education. The concept about NL was knocked by 77.1% of them. This percentage was significantly higher according to the level of their studies (primary 7.1%, secondary 32.1% and higher studies 60.9%; p < 0.0001) and also regarding the age range (42.3% vs. 25% of over that 50, p < 0.05). 73.8% always or almost always readied NL; 67.7% of those who declared that always readied were women and 71% had higher education. 53.8% of people over 50 years were not capable of reading labels due to the small letters. The most interesting information for the consumers was: calories (61%), fats (39%) and cholesterol (25.7%). Nutritional concepts questions had a low percentage of right answers, especially in volunteers with lower level of education and among older age groups. CONCLUSIONS: Results show that consumers have a low level of nutrition information that would enable a better choice to purchase food. Nutrition education is needed should be necessary to NL had a significant impact on the foods election. Therefore, this fact could contribute to the maintenance of health and disease prevention.

Análisis de las encuestas sobre etiquetado nutricional realizadas en el Hospital La Paz de Madrid durante la 9ª edición del 'Día Nacional de la Nutrición (DNN) 2010' / Knowledge of nutrition labelling in general population. assessment surveys conducted in la Paz University Hospital in Madrid during the 9th 'National Nutrition day 2010'

Introducción: El etiquetado nutricional es toda la información en relación con el valor energético y los nutrientes que componen al alimento y representa una valiosa herramienta para ayudar a los consumidores a tomar decisiones informadas acerca de su dieta y estilo de vida. Sin embargo, es poco conocido como percibe el consumidor esta información. Objetivos: Conocer el grado de información de la población encuestada sobre el etiquetado nutricional y evaluar aspectos como atención, lectura, comprensión y uso del mismo. Materiales y métodos: 200 voluntarios que asistieron el día 28 de mayo de 2010 (Día Nacional de la Nutrición DNN) al Hospital La Paz y completaron un cuestionario sobre etiquetado nutricional autoadministrado, consistente en 10 preguntas cerradas de opción múltiple. Resultados: El colectivo entrevistado (66,7% mujeres y 33,3% hombres) presentaba una edad media de 42,0 ± 15 años y un IMC de 24,1 ± 3,8 kg/m2. Un 86,5% tenía estudios medios y superiores. Un 77,1% conocía el concepto del etiquetado nutricional. El porcentaje fue significativamente mayor entre aquellos con estudios superiores (primarios 7,1%, medios 32,1% y superiores 60,9%; p < 0,0001) y en las edades comprendidas entre 30-49,9 años (42,3% vs 25% en mayores de 50 años, p < 0,05). Un 73,8% declaró que leía el EN siempre o casi siempre; entre aquellos que declararon que los leían siempre 67,7% fueron mujeres y 71% tenía estudios superiores. Un 53,8% de los mayores de 50 años declaró no poder leer el etiquetado debido al tamaño reducido de las letras. La información que despierta mayor interés sobre los consumidores son las calorías (61%), las grasas (39%) y el colesterol (25,7%). Las preguntas relacionadas con conocimientos nutricionales tuvieron un bajo porcentaje de respuestas correctas, sobre todo en el grupo con menor nivel de estudios y entre las personas mayores. Conclusiones: Los resultados obtenidos muestran que la población presenta un nivel bajo de información nutricional que permita hacer una mejor elección de los productos que se compran. La educación nutricional es necesaria para que el etiquetado nutricional tenga impacto en la elección de los alimentos, ya que permite informar y concienciar a la población sobre como la dieta puede contribuir al mantenimiento de la salud y la prevención de la enfermedad (AU)
