Extra virgin olive oil (EVOO) consumption and antioxidant status in healthy institutionalized elderly humans

Recent studies show that the elderly have increased oxidative stress and impaired antioxidant defense systems. Our study aims to evaluate the effects of daily consumption of EVOO in the healthy institutionalized elderly. We studied anthropometric, biochemical and antioxidant parameters in 62 subjects aged 65-96 years after a 6-week daily intake of polyphenol-rich EVOO with high oleuropein derivative contents. Subjects were divided into a control group (CG) who maintained their dietary habits (n=39) and an olive group (OG) who consumed EVOO as the only added fat, plus a daily dose of 50ml (n=23). We found a significant reduction of total cholesterol (TC), HDL, LDL and TGs in OG subjects and a significant increase of HDL levels. There was no significant variation in the CG parameters. In OG the total antioxidant capacity (TAC) in plasma increased with significant differences over CG. Plasma hydroxytyrosol (OH-Tyr) concentration showed a significant increase after EVOO intervention. Daily consumption of EVOO was found to have positive effects on lipid profiles, OH-Tyr levels and TAC. The results also show a significant increase of catalase (CAT) in erythrocytes and a decrease (p<0.05) in superoxide dismutase (SOD) and glutathione peroxidase (GH-PX) activity after EVOO intake. To our knowledge, no other study has examined the effects of EVOO consumption on biochemical parameters, antioxidant capacity and antioxidant enzyme activity in healthy elderly subjects. In conclusion, our results show that nutritional intervention with EVOO improves antioxidant status in healthy elderly people.

Actividad física, dieta mediterránea, capacidad aeróbica y clima motivacional hacia el deporte en escolares de la provincia de Granada: un modelo de ecuaciones estructurales

INTRODUCTION the school stage represents a period of risk in the development of habits such as sedentary digital leisure, which favours future pathologies such as obesity. The practice of Physical Activity and the level of adherence to the Mediterranean Diet (MD) allows its prevention, being essential to promote motivational climates in sport that support a healthy lifestyle. MATERIAL AND METHODS the present study was carried out in a sample of 692 schoolchildren from the province of Granada. This research aims to develop a structural equation model that allows to analyse the relationships between motivational climate, healthy habits and maximal oxygen uptake. The main instruments used were the PMCSQ-2, KIDMED, PAQ-C and CERV. RESULTS the results show a direct relationship between the practice of PA, Task Climate and Ego Climate. PA was positively correlated with the use of videogames and maximum oxygen uptake. The problematic use of video games was positively associated with Ego Climate and negatively related to the level of adherence to the MD. Finally, Ego Climate was positively related to the level of adherence to MD. CONCLUSION the practice of PA oriented to Task Climate promotes a lifestyle more active, which improves the maximal oxygen uptake, reduces the sedentary digital leisure and is associated to a better dietary pattern. The ego-oriented goals also is associated with the quality of the diet, revealing the need to promote a physical-sports practice that favours intrinsic and extrinsic motivations.

espanolIntroduccion: La autoestima parece ser un importante predictor de sintomas depresivos entre los jovenes, y sobre todo en el genero femenino. Algunos autores sugieren que la existencia de sobrepeso y/o obesidad en jovenes se relaciona con una menor autoestima asi como la participacion deportiva se ha asociado con unos valores mas altos de la misma. Objetivos: Analizar las relaciones existentes entre el indice de masa corporal, sexo, aceptacion a las clases de Educacion Fisica y autoestima en una muestra representativa de escolares de 3o y 4o de Educacion Secundaria Obligatoria de la ciudad de Alicante. Metodos: El estudio se llevo a cabo sobre una muestra representativa compuesta por 1.150 alumnos escolarizados en la ciudad de Alicante. Se obtuvieron datos sociodemograficos, antropometricos, valores de autoestima y de aceptacion por las clases de educacion fisica. Resultados: Existe una correlacion positiva entre la aceptacion a las clases de educacion fisica y el autoestima (r= ,319) y una correlacion negativa entre esta y el sexo de los alumnos (r= -,289), siendo el grupo femenino el que muestra unas menores puntuaciones. Existe una correlacion negativa entre el autoestima y los valores de indice de masa corporal (r= -,083), y el sexo (r= -,308), siendo el grupo femenino el que muestra unos valores menores de autoestima. Conclusiones: En vista de los resultados se hace necesario planificar actuaciones encaminadas a reforzar y aumentar la autoestima durante la adolescencia, centrandose en los grupos de riesgo formados por los jovenes con sobrepeso/obesidad y sobre por el grupo de las chicas. EnglishIntroduction: Self-esteem seems to be an important predictor of depressive symptoms in adolescents, especially in females. Some authors suggest that there is a relationship between adolescents with overweight or obesity and lower self-esteem. In addition, sports participation has been associated with a higher self-esteem. Objectives: To analyses the relationships between BMI, gender, acceptance for physical education classes and self-esteem in a representative sample of 14-16 years students of the Alicante city. Methods: Research was conducted with a representative sample of 1,150 students (15.1 ± 0.8 years) of the Alicante city. Data included their socio-demographic background, anthropometric measurements, self-esteem and acceptance for physical education classes. Results: There is a positive correlation between acceptance for physical education classes and selfesteem (r= .319) and there is a negative correlation between this acceptance and gender (r= -.289), lower scores were shown in a female group. There is a negative correlation between self-esteem and BMI (r= -.083) and gender (r= -.308), lower self-esteem were shown in a female group. Results: It is necessary to plan actions aimed as reinforcing and increasing self-esteem during the adolescent period, focusing on the group of girls and the group of young adults with overweight and obesity problems and especially in the girl group.INTRODUCTION Self-esteem seems to be an important predictor of depressive symptoms in adolescents, especially in females.
