Consumo de alimentos y calidad de la dieta en estudiantes universitarios: Proyecto uniHcos
Antecedentes/Objetivos: La etapa universitaria se caracteriza por cambios en estilos de vida y, la alimentación es uno de los de mayor variación, especialmente en los primeros cursos. El objetivo de este estudio es describir la frecuencia de consumo de alimentos y la calidad de la dieta de los universitarios españoles. Métodos: Estudio observacional, descriptivo, transversal, multicéntrico de estudiantes universitarios de primer año participantes en el proyecto uniHcos. Población de 1363 estudiantes, 72,6% mujeres y 27,4% hombres de 6 universidades españolas. Los participantes respondieron un cuestionario online de frecuencia de consumo de alimentos: A diario; 3-4 veces/semana pero no diario; 1-2 veces/semana; < 1 vez/semana; Nunca/casi-nunca. Para interpretar los resultados los alimentos se categorizaron según guías-dietéticas SENC-2004 en consumo: diario (pasta, pan-cereales, fruta, verduras, lácteos); semanal (carnes, huevos, pescado, legumbres) y ocasional (embutidos, dulces, refrescos con azúcar. A partir de estos datos se calculó el Índice de Alimentación Saludable (IASE) para determinar la calidad de la dieta. Se clasificó en saludable, necesita cambios y poco saludable. Se realizaron estadísticos descriptivos mediante el software estadístico SPSS 20.0. Resultados: El 38,1% de los universitarios consumen frutas a diario, 21,4% verduras, 74,5% lácteos, 60% pan-cereales y 15% pasta. Semanalmente, el 55,3% consumen carne 3-4 veces/semana, 20,7% huevos, 22,2% pescado y 25,5% legumbres. Además, el 13,3%, 22,2% y 10,2% de los universitarios declaran consumir a diario embutido, dulces y refrescos con azúcar respectivamente. Estos resultados van en concomitancia con los del IASE estadísticamente significativos (p-valor < 0,001), donde se muestra que 6,5% de los universitarios se alimentan saludablemente (mujer: 6,9%; hombre: 5,3%), frente a 78% que necesitan cambios (mujer: 76,7%; hombre: 81,3%) y 15,6% que presentan una alimentación poco saludable, siendo mayor en mujeres (16,4%) que en hombres (13,4%). Conclusiones: La alimentación de los universitarios españoles sigue siendo poco saludable y necesitando cambios, como muestran otros estudios en población universitaria. Los patrones alimentarios de consumo semanal de embutidos, dulces, como el de frutas, verduras y pasta, muestra una inversión de la alimentación saludable y, por tanto un problema de salud pública que requiere de atención por ser población que inicia su camino universitario.Plan Nacional Sobre Drogas (2010I145)

Patterns of Alcohol Consumption and Use of Health Services in Spanish University Students: UniHcos Project
[EN] The aim of the study was to examine the association of alcohol consumption patterns (hazardous alcohol use and binge drinking) and the use of emergency services and primary care consultations in university students. An observational, descriptive, cross-sectional study was conducted at eleven Spanish universities collaborating within the uniHcos Project. University students completed an online questionnaire that assessed hazardous alcohol use and binge drinking using the AUDIT questionnaire and evaluated the use of emergency services and primary care. A descriptive analysis of the data was performed, as well as the chi-squared test and Student’s t-test and nonconditional logistic regression models to examine this association. Results: There were 10,167 participants who completed the questionnaire. The prevalence of hazardous alcohol use was 16.9% (95% CI: 16.2–17.6), while the prevalence of binge drinking was 48.8% (95% CI: 47.9–49.8). There were significant differences in the use of emergency services in those surveyed with hazardous alcohol use (p < 0.001) or binge drinking pattern (p < 0.001). However, no significant differences were observed in terms of attendance during primary care visits in individuals with hazardous alcohol use (p = 0.367) or binge drinking pattern (p = 0.755). The current study shows the association between university students with a pattern of hazardous alcohol use or binge drinking and greater use of emergency services. However, no significant association was observed between the said consumption patterns and the use of primary care services.S

Menstrual problems and lifestyle among Spanish university women
ABSTRACT: Menstrual problems affect many young women worldwide, conditioning both their academic performance and quality of life. This study sought to analyse the prevalence of menstrual problems and their possible relationship with lifestyle among Spanish university women, as part of a research project (UniHcos Project) involving a cohort of 11 Spanish universities with 7208 university students. A descriptive analysis was performed using the bivariate chi-square test and the Student’s t-test together with a binary logistic regression, in which the dependent variable was ‘suffering from menstrual problems’. Menstrual problems were identified in 23.8% of the students, representing women who paid more visits to the doctor and to emergency rooms, and who consumed more painkillers and contraceptives. In relation to dietary preferences, menstrual problems were 1.39 (CI 95% 1.22–1.61; p = 0.000) times more likely among women classified as high-risk alcohol users according to the AUDIT questionnaire, and 1.187 (CI 95% 1.029–1.370; p = 0.019) times greater among those who consumed sweets daily, 1.592 (CI 95% 1.113–2.276; p = 0.011) times more frequent among those who eat fish daily, and 1.199 (CI 95% 1.004–1.432; p = 0.045) times greater among those who were dieting. Menstrual problems affect many college students and potentially modifiable lifestyle variables exist which may influence their prevalence. It would be interesting to develop programmes to promote women’s health in the university context.This research was funded by the National Drug Plan, Ministry of Health, Social Services and Equality of Spain (Grant numbers: 2010|145 and 2013|034) and Instituto de Salud Carlos III (Grant number: PI16/01947)
Alcohol use and family-related factors among Spanish university students: the unHicos project
[EN] Background During adolescence and youth there are relevant changes in the consolidation, gain or loss of consumption habits and lifestyles and the family factors has a fundamental role to development these habits. The study of the consumption of toxins, such as alcohol intake, is crucial at this stage due to the repercussions that said consumption presents in adulthood. Therefore, the objective of our study was to evaluate the associations between alcohol consumption patterns and related family factors (family functioning, family history of alcohol consumption) in Spanish university students. Methods Observational, descriptive, cross-sectional, multicenter study, carried out in first-year university students from 11 Spanish universities. Through an online questionnaire, alcohol consumption (risky consumption and intensive consumption or binge drinking), family functioning and history of alcohol in the family were evaluated. Risky alcohol consumption and binge drinking were assessed using the AUDIT test, and family functioning was assessed using the family APGAR questionnaire. A descriptive analysis of the data was performed, as well as the Chi-Square test and Student's T-Test, and non-conditional logistic regression models were carried out to examine this association. Results The prevalence of risky alcohol consumption identified in the 10,167 respondents was 16.9% (95% CI = 16.2–17.6), and that of BD was 48.8% (95% CI = 47.9–48.8). There is a significant association between risky alcohol consumption and family functioning in students of both sexes, with greater consumption in the face of severe dysfunctional support (men OR = 1.72; p < 0.001 and women OR = 1.74; p < 0.001) and family history of consumption (p = 0.005). Regarding the binge drinking pattern, no statistically significant differences were observed. Conclusions Risky alcohol consumption in university students is associated with dysfunctional family support, unlike the binge drinking pattern, where there is no such association. The findings of this study show the importance of creating prevention programs focused on the family approach in university students, which include alcohol screening in the population with a family history of this substance, and greater social support from health servicesSIThis work was supported by the National Drug Plan, Ministry of Health, Social Services and Equality of Spain (Codes: 2010|145, 2013|034 and 2020|030) and project PI16/01947
Guiding structures with multiply connected cross-sections: evolution of propagation in external fields at complex Robin parameters
Properties of the two-dimensional ring and three-dimensional infinitely long
straight hollow waveguide with unit width and inner radius in the
superposition of the longitudinal uniform magnetic field and
Aharonov-Bohm flux are analyzed within the framework of the scalar Helmholtz
equation under the assumption that the Robin boundary conditions at the inner
and outer confining walls contain extrapolation lengths and
, respectively, with nonzero imaginary parts. It is shown that,
compared to the disk geometry, the annulus opens up additional possibilities of
varying magnetization and currents by tuning imaginary components of the Robin
parameters on each confining circumference; in particular, the possibility of
restoring a lossless longitudinal flux by zeroing imaginary part of the
total transverse energy is discussed. The energy turns real under
special correlation between the imaginary parts of and
with the opposite signs what physically corresponds to the
equal transverse fluxes through the inner and outer interfaces of the annulus.
In the asymptotic case of the very large radius, simple expressions are derived
and applied to the analysis of the dependence of the real energy on
and . New features also emerge in the magnetic
field influence; for example, if, for the quantum disk, the imaginary energy
is quenched by the strong intensities , then for the annulus this
takes place only when the inner Robin distance is real;
otherwise, it almost quadratically depends on with the corresponding
enhancement of the reactive scattering. Closely related problem of the hole in
the otherwise uniform medium is also addressed for real and complex
extrapolation lengths with the emphasis on the comparative analysis with its
dot counterpart.Comment: 37 pages, 9 figure

Psychological Distress, Family Support and Employment Status in First-Year University Students in Spain
[EN] Mental disorders are consistently and closely related to psychological distress. At the start of the university period, the relationship between a student’s psychological distress, family support, and employment status is not well-known. The aims of this study were: To determine the prevalence of psychological distress in first-year university students and to analyze its relationship with family support and the student’s employment status. Data from 4166 first-year university students from nine universities across Spain were considered. The prevalence of psychological distress was obtained using the GHQ-12, a valid and reliable screening tool to detect poor mental health. To analyze the relationship between psychological distress, family support, and employment status, logistic regression models were fitted. Regarding the prevalence found, 46.9% of men and 54.2% of women had psychological distress. In both genders, psychological distress levels increased as family support decreased. Among women, psychological distress was associated with their employment status. The prevalence of psychological distress among first-year university students in Spain is high. In addition, family support, and employment status for women, could be factors to take into account when developing psychological distress prevention strategies at the beginning of the university period.S
Consumo de drogas ilegales, apoyo familiar y factores relacionadosen estudiantes universitarios. Un estudio transversal basado en datosdel Proyecto uniHcos
Objective: To assess the prevalence of illegal drug use in college students on any previous occasion, duringthe previous year and the previous month, and to analyze the relationship between illegal drug use andfamily support and other factors.Methods: A cross-sectional study using data from students participating in the uniHcos project (n = 3767)was conducted. The prevalence and age of onset of consumption of cannabis, non-prescription sedatives,stimulants and depressants was evaluated. Polyconsumption was also assessed. The independent vari-ables were: family support, age, residence, and employment status. To determine the factors related todrug use multivariate logistic regression models stratified by gender were fitted.Results: Differences between men and women in prevalence of illegal drug use except non-prescriptionsedatives were observed. In both genders, less family support was associated with higher consumptionof all drugs, except depressants, and with polyconsumption. To be studying and looking for work wasrelated to cannabis and stimulant use and to polyconsumption among women, but only to cannabis useamong men.Conclusions: These results support the notion that the start of university studies is a particularly relevantstage in the onset of illegal drug use and its prevention, and that consumption may be especially associatedwith family support.Objetivo: Evaluar la prevalencia del consumo de drogas ilegales en estudiantes universitarios y analizarla relación entre dicho consumo, el apoyo familiar y otros factores.Método: Se realizó un dise?no transversal basado en datos de participantes en el proyecto uniHcos (n =3767). Se evaluaron la prevalencia y la edad de inicio del consumo de cannabis, tranquilizantes sin receta,estimulantes y depresores, y el policonsumo. Como variables independientes se consideraron el apoyofamiliar, la edad, la residencia y la situación laboral. Para la determinación de los factores asociados alconsumo de drogas se ajustaron modelos de regresión logística estratificados por sexo.Resultados: Se observaron diferencias entre hombres y mujeres en la prevalencia del consumo de todaslas drogas ilegales, excepto tranquilizantes sin receta. En ambos sexos, cuanto peor apoyo familiar, mayorconsumo de todas las drogas, excepto depresores y policonsumo. Encontrarse estudiando y buscandotrabajo se relacionó con el consumo de cannabis, estimulantes y policonsumo en las mujeres, y solo concannabis en los hombres.Conclusiones: Los resultados de este estudio aportan nueva evidencia a favor de que el inicio de la etapauniversitaria es un momento de especial relevancia en el inicio del consumo de drogas ilegales y suprevención, pudiendo este consumo estar especialmente relacionado con el apoyo familiar
