[Evolution of the diet and physical activity of university students after the COVID-19 pandemic]. / Evolución de la dieta y la actividad física de los estudiantes universitarios tras la pandemia de COVID-19.

Introduction: Objective: to assess the evolution of adherence to Mediterranean diet and level of physical activity of university students of Health Sciences in Castilla-La Mancha during the COVID-19 lockdown and one year afterwards. Methods: a cross-sectional observational study using questionnaires on adherence to the Mediterranean diet and level of physical activity. A total of 893 students enrolled in Health Sciences degrees at the University of Castilla la Mancha participated, 575 in the first survey (during the lockdown) and 318 in the second (one year later). By sex, 672 women and 221 men (in the first survey 77.7 % were women and 22.3 % men while in the second survey these were 70.8 % and 29.2 %, respectively). Adherence to the Mediterranean diet was assessed with the Mediterranean Diet Adherence Screener (MEDAS) questionnaire and the modified Prevention with Mediterranean Diet (PREDIMED) questionnaire. The level of physical activity was assessed with the Rapid Assessment of Physical Activity Scale (RAPA). Results: one year after the COVID-19 confinement, consumption of olive oil has almost tripled. Daily fruit consumption has also doubled. Similarly, the consumption of wine and alcoholic beverages has doubled. Conversely, there was a reduction in the consumption of butter and margarine, as well as of carbonated drinks and sweetened beverages. Likewise, the percentage of university students with high adherence to the Mediterranean diet increased significantly (from 26 % to 34.3 %). Regarding physical activity level, there was a significant increase in the percentage of university students who engaged in light, moderate and even intense physical activity on an irregular basis. This increase was not found in the case of muscular strength and flexibility training activities. Conclusion: the results of the study indicate that, although the levels of adherence to the Mediterranean diet and physical activity have improved after the COVID-19 confinement, adherence to Mediterranean diet and physical activity level among the university population analyzed is still low. It is necessary to implement strategies for the achievement or maintenance of a healthy lifestyle in this population.

Introducción: Objetivo: valorar la evolución de la adherencia a la dieta mediterránea y el nivel de actividad física de los estudiantes universitarios de Ciencias de la Salud de Castilla-La Mancha durante la pandemia de COVID-19 y un año después de la misma. Método: estudio observacional transversal mediante cuestionarios sobre la adherencia a la dieta mediterránea y el nivel de actividad física. Participaron 893 alumnos matriculados en grados de Ciencias de la Salud de la Universidad de Castilla-La Mancha, 575 en la primera encuesta (durante la pandemia) y 318 en la segunda (un año después). Por sexos, 672 mujeres y 221 hombres (en la primera encuesta, el 77,7 % eran mujeres y el 22,3 % hombres, mientras que en la segunda lo eran el 70,8 % y 29,2 %, respectivamente). La adherencia a la dieta mediterránea se valoró con el cuestionario Mediterranean Diet Adherence Screener (MEDAS) y el cuestionario de Prevención con Dieta Mediterránea (PREDIMED), modificado. El nivel de actividad física se valoró con el cuestionario Rapid Assessment of Physical Activity Scale (RAPA). Resultados: tras un año desde el confinamiento por la COVID-19, el consumo de aceite de oliva casi se ha triplicado. Se ha duplicado también el consumo de frutas diario. De igual modo, se ha duplicado el consumo de vino y bebidas alcohólicas. Por el contrario, se encontró una reducción del consumo de mantequilla y margarina, al igual que de bebidas carbonatadas y azucaradas. Asimismo, aumentó significativamente el porcentaje de estudiantes universitarios con adherencia alta a la dieta mediterránea (del 26 % al 34,3 %). En cuanto al nivel de actividad física, ha aumentado significativamente el porcentaje de estudiantes universitarios que realizan actividad fisica ligera, moderada e incluso intensa de forma irregular. Este aumento no se ha encontrado en el caso de las actividades de fuerza muscular y flexibilidad. Conclusión: los resultados del estudio nos indican que, aunque los niveles de adherencia a la dieta mediterránea y de actividad física han mejorado tras el confinamiento por la COVID-19, la adherencia a la dieta mediterránea y el nivel de actividad física de la población universitaria analizada siguen siendo bajos. Es necesario aplicar estrategias para la consecución o mantenimiento de un estilo de vida saludable en dicha población.

Meeting 24 h Movement Guidelines and Health-Related Quality of Life in Youths during the COVID-19 Lockdown

Limitations in the use of public spaces have impacted the frequency and duration of movement behaviours (physical activity, sedentary behaviour, sleep) and outdoor activities of children and adolescents. Whether pandemic-induced changes in movement behaviours are related to the health-related quality of life (HRQoL) of children and adolescents is unknown. The aim of the current study was to examine the association between meeting 24 h movement guidelines and HRQoL during the COVID-19 lockdown among children and adolescents. Data from 1099 3–17-year-old children and adolescents from Spain and Brazil were analysed. An online questionnaire was used to collect parent-reported information concerning physical activity, screen time, and sleep duration. For the assessment of HRQoL, the EQ-5D-Y proxy version was used. The highest prevalence of reported problems was related to the 'worries/sadness/unhappiness' factor, where 36.3% of participants declared to have at least 'some problems'. Participants meeting the 24 h guidelines had a higher HRQoL score compared with those who did not (91.9 ±2.5 vs. 84.3 ±0.5, respectively;p < 0.05). The current study shows that children and adolescents that met 24 h movement guidelines presented a higher HRQoL during the COVID-19 lockdown, providing support for the promotion of healthy movement behaviours-especially during a pandemic.

Dietary Patterns, Adherence to the Food-Based Dietary Guidelines, and Ultra-Processed Consumption During the COVID-19 Lockdown in a Sample of Spanish Young Population.

Purpose: The aim of this study was to explore the dietary patterns, adherence to Food-Based Dietary Guidelines, and the ultra-processed consumption during the COVID-19 lockdown among a Spanish young population aged 3-17 years. Methods: Parents/legal guardians of preschoolers, children, and adolescents aged 3-17 years were enrolled through social networks. The eating habits were assessed by a Food Propensity Questionnaire applied in the ENALIA (Encuesta Nacional de Alimentación en la población Infantil y Adolescente) Spanish survey, which aims to collect food intake information and other data about eating habits on children and adolescents (0-18 years old). Participants were dichotomized following the Food-Based Dietary Guidelines for the Spanish young population offered by the Spanish Society of Community Nutrition. The ultra-processed food score was determined following the principles established in the NOVA classification. Results: Data from 604 children and adolescents were included. An association between age group and the recommendations of snacks (p = 0.002), fruits (p = 0.010), and diaries (p < 0.001) was found. Adolescents showed a lower mean compliance with these guidelines than children (p = 0.004) and preschoolers (p < 0.001). Similarly, children reported lower Food-Based Dietary Guidelines than preschoolers (p = 0.015). Regarding ultra-processed consumption, it was also observed a higher intake in adolescents than in children (p = 0.037), as well as in preschoolers (p < 0.001). Conclusions: The associations that were found highlight the low proportion of the young population (especially adolescents) meeting the Food-Based Dietary Guidelines and the high consumption of ultra-processed foods during COVID-19 lockdown.

[Perception of loneliness, happiness, and health, and quality of diet. The moderator role of weight status]. / Percepción de soledad, felicidad y salud, y calidad de la dieta. El rol moderador del estado ponderal.

INTRODUCTION: Aim: to determine the relationship between perceived loneliness, happiness, and health, and quality of diet, observing the moderator role of weight status in elementary school children during the state of alarm decreed for COVID-19. Methods: a descriptive, cross-sectional study in a sample of 116 Spanish schoolchildren. The perception of loneliness, happiness, and health was assessed using three items of the Health Behavior in School-aged Children questionnaire. The quality of their Mediterranean diet was assessed using the Mediterranean Diet Quality Index quetsionnaire for children and adolescents. Anthropometric variables were collected through a self-reported questionnaire, and for the calculation of body mass index the Quetelet index (kg/m2) was used. Results: the descriptive analysis showed no differences in the perception of loneliness, happiness, or health, quality of diet, or anthropometric variables (p > 0.005), except for weight (p < 0.005), according to sex. The inferential analysis showed that higher values in quality of diet are correlated with higher scores in perceived happiness and health (p < 0.005). In turn, the linear regression test showed an association between quality of diet and perception of happiness after the model was adjusted for normal weight (R2 = 0.382; p < 0.005). Likewise, it showed a significant association between quality of diet and perception of health after the model was adjusted for overweight schoolchildren (R2 = 0.455; p < 0.005). Conclusion: the association between perceived health and happiness with quality of diet seems to be moderated by weight status.

INTRODUCCIÓN: Objetivo: determinar la relación existente entre la percepción de soledad, felicidad y salud, y la calidad de la dieta, observando el rol moderador del estado ponderal en escolares de primaria durante el estado de alarma decretado por la COVID-19. Métodos: estudio descriptivo transversal de una muestra de 116 escolares españoles. Las percepciones de soledad, felicidad y salud se valoraron mediante tres ítems del cuestionario Health Behavior in School-aged Children. La calidad de la dieta mediterránea se valoró a través del cuestionario Índice de calidad de la dieta mediterránea en niños y adolescentes. Las variables antropométricas se recogieron a través de un cuestionario autoinformado y para el cálculo del índice de masa corporal se empleó el índice de Quetelet (kg/m2). Resultados: el análisis descriptivo no mostró diferencias en la percepción de soledad, felicidad y salud, la calidad de la dieta, y las variables antropométricas (p > 0,005), a excepción del peso (p < 0,005), según el sexo. El análisis inferencial mostró que los valores más elevados en la calidad de la dieta se correlacionan con valores más altos en la percepción de felicidad y de salud (p < 0,005). Por su parte, la prueba de la regresión lineal mostró asociación entre la calidad de la dieta y la percepción de felicidad tras ajustarse el modelo al normopeso (R2 = 0,382; p < 0,005). Asimismo, mostró una asociación significativa entre la calidad de la dieta y la percepción de salud tras ajustarse el modelo a los escolares con sobrepeso (R2 = 0,455; p < 0,005). Conclusión: la asociación entre la percepción de salud y de felicidad con la calidad de la dieta parece estar moderada por el estado del peso.
