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
