Confirmation and characterization of neglected WDS systems using Gaia DR3 and the Virtual Observatory

The aim of this paper is, making use of the Gaia DR3 catalogue and Virtual Observatory tools, to confirm and characterize 428 binary and multiple stellar systems classified as neglected (only one observation) in the Washington Double Star Catalogue (WDS). The components of the stellar systems have the same parallax and proper motion (within the errors) and are separated by less than 50 000 AU, which minimizes the number of by-chance counterparts. Effective temperatures calculated using VOSA were used to estimate stellar masses. Binding energies were calculated for 42 binary systems confirming they are physical pairs. Also we found 75 pairs with F/G- M spectral types which are very interesting to improve the determination of the metallicity of the M star from the higher-mass component.Comment: 10 pages, 10 figure

Association of Adherence to Specific Mediterranean Diet Components and Cardiorespiratory Fitness in Young Adults

Objective: Cardiorespiratory fitness (CRF) and a healthy diet may be part of an overall healthy lifestyle. The association between cardiorespiratory fitness and adherence to an overall Mediterranean Diet (MedD) pattern and specific MedD foods has been assessed. Design: Subjects completed a lifestyle survey and dietary pattern, using the validated MedD Adherence 14-item questionnaire and two self-reported 24-h dietary recalls. Participants' height, body weight, waist circumference (WC), and CRF (maximum oxygen uptake, VO2max, ml/kg/min) were measured. Setting: University of Cadiz, Spain. Subjects: A sample of young adults (n = 275, 22.2 +/- 6.3 years). Results: Mean VO2max was 43.9 mL/kg/min (SD 8.5 mL/kg/min). Most participants had healthy CRF (75.9%). The average MedD score was 6.2 points (SD 1.8 points). Participants who consumed more servings of nuts had higher VO2max. Those who showed low CRF performed less physical activity (PA) and had a higher body mass index (BMI) and WC compared with those classified as having healthy CRF. Nut consumption was positively associated with VO2max (beta = 0.320; 95% CI 2.4, 10.7; p < 0.002), adjusting for sex, age, smoking PA, BMI, WC, and energy intake, showing the subjects who consumed more nuts were fitter than young adults who consumed less. Conclusions: CRF is positively associated with nut consumption but not with the overall MedD pattern and all other MedD foods in the young adults. The subjects who consumed more servings of nuts were fitter than young adults who consumed less. Moreover, fitter subjects performed more PA and had a lower BMI and WC than those who had lower fitness levels

Calidad de vida y sus factores determinantes en universitarios españoles de Ciencias de la Salud

La calidad de vida en la población universitaria adquiere una especial importancia ya que permite obtener información sobre las condiciones de vida de los universitarios y, sobre todo, de cómo éstos las perciben. Objetivo: Evaluar la calidad de vida de los universitarios que cursan estudios en ciencias de la salud y su relación con diferentes factores tales como: hábitos de vida, parámetros antropométricos y la influencia de las distintas variables sobre su percepción. Material y Método: Estudio transversal de una muestra de 1.753 estudiantes de ciencias de la salud de nueve universidades españolas con diseño muestral aleatorio y estatrificado según curso y facultad al que se le aplicó un cuestionaro ad hoc que recogía todas las variables a estudio. Resultados: La calidad de vida percibida por los participantes fue Me = 75. Los factores explorados de la calidad de vida se co-relacionaron significativamente con la percepción global de calidad de vida de los estudiantes (p<0,001). Se establecieron 3 dimensiones y el impacto de cada una de ellas sobre la percepción de calidad de vida global fue p<0,001. Los varones percibieron mejor calidad de vida que las mujeres y también los estudiantes con menor Índice de Masa Corporal (IMC). Conclusión: Los universitarios son una población clave para realizar actividades de promoción y prevención de la salud por lo que resulta necesario crear mejores infraestucturas y recursos educativos para mejorar la CV y fomentar hábitos y estilos de vida saludable con especial atención en la alimentación y la realización de una adecuada actividad física.Abstract Introduction: The quality of life of university students acquires special importance because it provides information about their life conditions and especially how they perceive it. Objetive: Evaluate the quality of life of students who are enrolled in health science studies and its relation with the following diverse factors: life and dietetic habits, anthropometric parameters and the influence of distinct variables on their perception. Methods: Transversal study of a sample of 1753 health science degree students of nine Spanish universities with a randomized design and stratified by course and faculty for which we applied an ad hoc questionnaire that considered all study variables. Results: The quality of life (QoL) perceived by the participants had a Median of 75. The factors that were explored about the quality of life correlated significantly with their global perception of it (p<0.001). Three dimensions were established and the impact of each one of them on their global perception of QoL was p<0.001. Men perceived better QoL then women and the students with lower Body Mass Index (BMI). Conclusions: University students are a key population for realizing health promotion and prevention activities therefore it is necessary to develop and provide better infrastructures and educative resources in order to enhance their QoL and to promote healthier habits and life styles with special attention on dietetics habits and the performance of an adequate physical activity

Estilos de vida asociados con sobrepeso y obesidad en adultos españoles.

Journal Article;OBJECTIVES To assess the relationship between life styles and eating habits with the overweight and obesity prevalence in a Spanish adult population. METHODS A population-based, cross-sectional study conducted on 2640 subjects older than 15 years, in Cádiz (Spain). Surveys were conducted in subjects' homes to obtain life styles, eating habits, and anthropometric data. Logistic regression has been used to study the association between the life style variables and overweight and obesity. RESULTS Prevalence of overweight and obesity in Cadiz is 37% and 17%, respectively; higher in males and increases with age. BMI has an inverse relationship with educational level (PR = 2.3, 1.57-2.38). The highest levels of obesity are associated with daily alcohol consumption (PR = 1.39, 1.29-1.50), greater consumption of television,and sedentary pursuit (PR 1.5, 1.07-1.24). A lower prevalence of obesity is observed among those with active physical activity (10.9% vs 21.6%), with differences between sex. Following a slimming diet is more frequent in the obese and in women but dedicate more hours than men to passive activities. In men is greater the consumption of alcohol, high energy foods and snacks. Overweight and obesity is associated with the male sex (OR = 3.35 2.75-4.07), high consumption of alcohol (OR = 1.38 1.03-1.86) and watching television (OR = 1.52 1.11-2.07), and foods likes bread and cereals (OR = 1.47 1.13-1.91). Exercise activities is a protective factor (OR = 0.76 0.63-0.98). CONCLUSIONS Life styles factors associated with overweight and obesity present different patterns in men and women and is necessary to understand them to identify areas for behavioural intervention in overweight and obesity patients.YesResumen Objetivo: Valorar la relación existente entre estilos de vida y hábitos alimentarios con la prevalencia de sobrepeso y obesidad en una población adulta española. Método: Estudio transversal de base poblacional realizado en 2.640 adultos mayores de 15 años en Cádiz(España). El estudio se llevó a cabo en el domicilio de los sujetos, recogiéndose mediante una encuesta los hábitos alimentarios y características de los estilos de vida. Resultados: La prevalencia de sobrepeso y obesidad en Cádiz es de 37% y 17% respectivamente, mayor en varones e incrementándose con la edad. El IMC muestra una relación inversa con el nivel educativo (RP = 2,3, 1,57- 2,38). Los mayores niveles de obesidad se asocian al consumo diario de alcohol (RP = 1,39, 1,29-1,50), mayor consumo de televisión y hábitos sedentarios (RP = 1,5, 1,07-1,24). Las menores cifras de prevalencia de obesidad se observan en los sujetos con una mayor actividad física (10,9% frente a 21,6%), aunque con diferencias entre sexos. Las mujeres dedican más horas que los hombres a actividades pasivas. Seguir dietas de adelgazamientos es mas frecuente en sujetos obesos y en mujeres. En hombres es mayor el consumo de alcohol, alimentos con elevado contenido calórico y comer entre horas. La presencia de sobrepeso y la obesidad se asocia con el sexo masculino (OR = 3,35 2,75-4,07), elevado consumo de alcohol (OR = 1,38 1,03-1,86) y televisión (OR = 1,52 1,11- 2,07), y con mayores consumos de alimentos del grupo de cereales y pan (OR = 1,47 1,13-1,91). La actividad física se comporta como factor protector (OR = 0,76 0,63-0,98). Conclusiones: Los estilos de vida asociados con el sobrepeso y la obesidad presentan diferentes patrones en hombres y mujeres. Es necesario estudiarlos para identificar áreas de intervención en pacientes con sobrepeso y obesidad
