This study sought to describe and compare adherence to the Mediterranean diet and consumption of local foods from the Huelva region among Spanish university women in relation to menstrual pain and other menstrual characteristics. This cross-sectional study included 311 health science students. The study variables were sociodemographic and gynecologic characteristics, adherence to the Mediterranean diet using the KIDMED questionnaire, alcohol consumption (SDU) and consumption of local food. A descriptive bivariate analysis and multiple binary regression were performed for menstrual pain. Up to 55.3% of participants had moderate adherence to the Mediterranean diet and only 29.6% had high adherence. Women with low adherence had longer menstrual cycles (p < 0.01). Eating less than two pieces of fruit per day (OR = 3.574; 95%CI = 1.474–8.665; p < 0.05) and eating pulses more than one day a week (OR = 2.320; 95%CI = 1.006–5.348) raised the probability of suffering menstrual pain. A positive correlation between SDU and cycle length was identified (r = 0.119, p = 0.038), and menstrual bleeding was lower in women who consumed olive oil daily (p = 0.044). In conclusion, the Mediterranean diet, alcohol consumption and consuming typical foods from southern Spain appear to influence cycle length, menstrual flow and menstrual pain. Further research is necessary to confirm and expand these findings.

Introducción: El uso excesivo de videojuegos ha aumentado de manera vertiginosa y, especialmente, entre los varones con edades comprendidas entre los 10 y los 19 años. Muchos adolescentes pierden el control sobre el videojuego, lo que puede tener consecuencias negativas como el juego patológico, problemático o la adicción al videojuego.Objetivos: Conocer la producción científica existente sobre el uso problemático de videojuegos y la adicción al videojuego en los adolescentes. Metodología: Se han analizado los documentos encontrados tras una búsqueda bibliográfica en las bases de datos COCHRANE, MEDLINE, LILACS, CINAHL y CUIDEN.Resultados: Se han definido los factores predictores, la prevalencia, las características, los cuestionarios validados, la relación con otras adicciones, la relación con el TEA (Trastorno del Espectro Autista) y con el TDAH (Trastorno por Déficit de Atención e Hiperactividad) y la prevención del uso problemático y la adicción al videojuego.Conclusiones: Hay inconsistencias en los resultados debido al diseño transversal de la mayoría de los estudios, a las muestras pequeñas, a la ausencia de muestras clínicas o aleatorizadas, a la extracción de datos con cuestionarios de autorreporte, a la realización de estos en colegios, sin tener en cuenta a los adolescentes ingresados en centros de salud mental u hospitales, a la falta de estudios en el género femenino y a la falta de estandarización de los criterios diagnósticos. El tema menos estudiado es el tratamiento y la prevención, el más importante para nuestra profesión, por lo que la principal futura línea de investigación sería en este ámbito. Introduction: The excessive use of videogames has increased dramatically, especially among 10-to-19-year-old males. Many teenagers lose control over video games, which may have negative consequences such as pathological, problematic, or addictive gaming.Objectives: Knowing the existing scientific production about the problematic use of video games and video games addiction in teenagers.Methodology: Documents found after a bibliographic search in the databases COCHRANE, MEDLINE, LILACS, CINAHL and CUIDEN have been analyzed.Results: It has been defined the predictive factors, the prevalence, the characteristics, the validated questionnaires, the associations with other addictions, the relations with ASD (Autism Spectrum Disorder) and ADHD (Attention-Deficit/Hyperactivity Disorder), and prevention of problematic use and addiction to video games.Conclusions: There are inconsistencies in the results due to the transversal design of most of the studies, such as small samples, the absence of clinical or randomized samples, data extraction with self-reporting questionnaires conducted in schools, without taking into account adolescents hospitalized into mental health centers or hospitals, the gender bias in research and the lack of standardization of diagnostic criteria. The least studied subject is the treatment and prevention, the most important for nursing profession, so the future main line of research would be in this area.

Stress contributes to the development and maintenance of obesity. Mindfulness-based therapies are being used to reduce stress and promote weight reduction and maintenance. This study aimed to determine the efficacy of mindfulness-based interventions for stress and weight reduction in the short, medium, and long term. Searches on PsycINFO, Medline, CINAHL, Scopus, WOS, and Science Direct were conducted until March 2021. Intervention studies with a sample of adults were included; these evaluated a mindfulness-based intervention and used stress and weight or body mass index as outcome variables. These criteria were met by 13 articles. A meta-analysis of 8 of the 13 articles was performed with a random-effects or fixed-effects model, depending on the level of heterogeneity between studies. Mindfulness-based interventions had a small effect on stress reduction over a 3-month period: effect size (standardized mean difference) = −0.29 (95% CI: −0.49, −0.10). However, no significant evidence was found for stress reduction from 3 months onwards, nor for weight or body mass index reduction in any period. Mindfulness-based interventions are effective in reducing stress in the short term, but not in the medium or long term, nor are they effective for weight or body mass index. More robust and longer study designs are needed to determine their effects.

Summary: Covid‐19 has triggered an unprecedented global health crisis. The highly contagious nature and airborne transmission route of SARS‐CoV‐2 virus requires extraordinary measures for its containment. It is necessary to know the behaviour of aerosols carrying the virus to avoid this contagion. This paper describes the behaviour of aerosols and their role in the transmission of SARS‐CoV‐2 according to published models using a scoping review based on the PubMed, Scopus, and WOS databases. From an initial 530 references, 9 papers were selected after applying defined inclusion criteria. The results reinforce the airborne transmission route as a means of contagion of the virus and recommend the use of face masks, extending social distance to more than 2 metres, and natural ventilation of enclosed spaces as preventive measures. These results contribute to a better understanding of SARS‐CoV‐2 and help design effective strategies to prevent its spread.

Emotional Eating (EE) patterns have been shown to play a relevant role in the development of overweight and obesity. The aim of this study was to analyze the factor structure and psychometric properties of the Emotional Eater Questionnaire (EEQ) in university students from Huelva. The EEQ was administered to 1282 students (age 22.00 (±5.10), BMI 23.59 (±6.74)), belonging to the University of Huelva. An exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were carried out. The internal structure of the questionnaire, internal consistency, test-retest reliability, and convergent validity were analyzed. Principal component analysis of the questionnaire showed two dimensions, explaining 56% of the variance. Internal consistency showed a Cronbach’s alpha of 0.859 globally, and of 0.841–0.855 if the items were removed. The corrected item-total correlation yielded values of 0.444–0.687. The test-retest stability was ICC = 0.924 (p < 0.001). The data showed significant correlations between EEQ and the rest of the variables, and a Spearman’s Coefficient ranging from −0.367 to 0.400. The fit indexes were good for the confirmatory factor analysis. The results obtained with this structure found an adequate reliability and validity of the questionnaire in comparison with previous studies.

The development of healthy eating habits in adolescence is perceived as an effective strategy to avoid health problems in adulthood. The involvement of educational centres’ governing boards, as well as the Educational State and Regional Administrations’, may be necessary to create healthy food environments during the school day. The objective of this study is to identify the relationship between students’ eating habits during the school day and sociodemographic, family and physical activity variables, as well as the existence of a school cafeteria. For this, a cross-sectional study in a stratified random sample of 8068 students of Public Secondary Education High Schools of Andalusia (Spain) has been carried out. The results show that students who are 14 years old or older are more likely to skip breakfast at home (odds ratio (OR): 1.81, 95% confidence interval (CI): 1.55–2.12) than those under this age. Students whose mothers do not have a university education are more likely to consume incomplete breakfasts (OR: 1.83, 95% CI: 1.26–2.65). Snacks with sweets (OR: 1.93, 95% CI: 1.67–2.23), candy in general (OR: 2.75, 95% CI: 2.38–3.19), and bagged crisps (OR: 3.06, 95% CI: 2.65–3.54) were more likely to be consumed in schools with a cafeteria. The factors that significantly influence the eating habits of secondary students in Andalusia include age, sex, parental level of education, physical activity and the existence of a cafeteria.
