Asociación entre sueño insuficiente, cambio en el tamaño de lasporciones, patrones alimentarios y sobrepeso/obesidad enestudiantes latinoamericanos / Association between insufficient sleep, change in portion size, eating patterns and overweight/obesity in latin american students

Fundamentos: El sueño es una función biológica de vital importancia ya que interviene en múltiples procesosbiológicos como la regulación energética, estando asociada una mala calidad y/o cantidad de sueño con elsobrepeso y la obesidad. El objetivo fue identificar la asociación de sueño insuficiente con cambios en el tamaño delas porciones, patrones alimentarios y sobrepeso/obesidad en estudiantes universitarios de América Latina.Métodos: Estudio transversal y multicéntrico. A los estudiantes, utilizando un cuestionario on-line, se les consultósobre su alimentación, horas de sueño, peso y estatura y otras variables sociodemográficas.Resultados: El estudio incluyó a 4.880 estudiantes, mayoritariamente mujeres (73,8%), la regresión no mostróasociaciones entre sueño insuficiente con estado nutricional y aumento del tamaño de las porciones de alimentos.En el modelo 3 (mayor ajuste) se observó que el sueño insuficiente se asoció con el consumo de infrecuente dedesayuno OR:1,22 (IC 95% 1,07-1,40) y frutas OR:1,16 (IC 95% 1,01-1,33), y no realizar actividad física OR:1,18(IC95% 1,03-1,34). Por otro lado, hubo asociaciones protectoras frente al sueño insuficiente como pertenecer alsexo femenino OR: 0,86 (IC 95% 0,74-0,99) y ser estudiantes de carreras de la salud OR:0,64 (IC 95% 0,56-0,73).Conclusiones: El estudio revela que el sueño insuficiente en estudiantes universitarios se asocia con no desayunartodos los días y consumir insuficiente fruta.(AU)

Background: Sleep is a biological function of vital importance since it intervenes in multiple biological processessuch as energy regulation, with poor quality and/or quantity of sleep being associated with overweight and obesity.The objective was to identify the association of insufficient sleep with changes in portion sizes, eating patterns andoverweight/obesity in university students in Latin America.Methods: Cross-sectional, multicenter study. Students, using an online questionnaire, were asked about their diet,hours of sleep, weight and height, and other sociodemographic variables.Results: The study included 4,880 students, mostly women (73.8%). The regression showed no association betweeninsufficient sleep with nutritional status and increased food portion size. In model 3 (higher adjustment), it wasobserved that insufficient sleep was associated with infrequent consumption of breakfast OR:1.22 (95% CI 1.07-1.40) and fruits OR:1.16 (95% CI 1.01-1.33), and no physical activity OR: 1.18 (95% CI 1.03-1.34), on the other handthere were protective associations against insufficient sleep such as belonging to the female sex OR: 0.86 (95% CI0.74-0.99) and being students of health careers OR:0.64 (95% CI 0.56-0.73).Conclusions: The study reveals that insufficient sleep in university students is associated with not eating breakfastevery day and insufficient fruit consumption.(AU)

Self-Reported Nutritional Status and Breakfast Characterization in Latin American University Students.

OBJECTIVE: To associate breakfast consumption frequency with self-reported nutritional status and dietary patterns of Latin American university students by human development. MATERIAL AND METHODS: This was a cross-sectional, multicenter observational study. University students from 11 Latin American countries (Argentina, Chile, Colombia, Costa Rica, Ecuador, Guatemala, Mexico, Peru, Paraguay, Panama and Uruguay) were invited to participate by answering an online self-administered questionnaire on food consumption and sociodemographic indicators, associations were investigated using logistic regression. RESULTS: The logistic regression analysis showed significant associations between breakfast consumption and the crude model, models 2 and 3 in countries with very high and upper-middle/high human development. However, after adjustment in the most comprehensive model, the association is no longer statistically significant. In the fully adjusted model of the variables, a significant relationship was observed between breakfast consumption and both healthy and unhealthy dietary patterns. Specifically, students who typically consume breakfast exhibit greater consumption of oatmeal and fruits, as well as healthier dinner choices. Conversely, they exhibit lower consumption of fast food, sugary drinks, and juices. In particular, in highly developed countries, along with the mentioned foods, consumption of dairy was linked to breakfast consumption in a positive way, while alcohol consumption was negatively associated. CONCLUSION: University students who eat breakfast on a regular basis maintain a healthier diet in comparison to those who do not, irrespective of their country's level of human development.

Etiquetado frontal de advertencia nutricional de alimentos y bebidas pre-envasados. Postura intersectorial de expertos en Centro América y República Dominicana / Front-of-package warning labelling system for pre-packaged foods and beverages: an intersectoral position of expertsin Central American and Dominican Republic

La región latinoamericana ha sido pionera en la implementación del etiquetado frontal de advertencia nutricional (EFAN), mismo que ha demostrado su eficacia y efectividad para identificar correctamente cuando un producto contiene cantidades excesivas de nutrientes asociados a Enfermedades no transmisibles (ENT). Sin embargo, ningún país del Sistema de la Integración Centroamericana (SICA); que incluye a Belice, Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua, Panamá y República Dominicana, lo ha adoptado. Por esta razón, el Instituto de Nutrición de Centro América y Panamá, convocó a un grupo de expertos de la academia y la sociedad civil con el objetivo de establecer una postura técnica, basada en la mejor evidencia científica, en relación al etiquetado frontal para los nutrientes críticos de alimentos y bebidas pre- envasados en la región centroamericana. Se presenta evidencia específica de la región del SICA que demuestran la superioridad del EFAN frente a otros etiquetados como las Guías Diarias de Alimentación (GDA), el semáforo y el Nutriscore para seleccionar opciones más saludables. Dentro del marco de los derechos de la niñez y de los consumidores, se brindan argumentos y se hace un llamado a los gobiernos para la pronta adopción del EFAN como una política costo-efectiva para la prevención de ENT. Además, se proveen recomendaciones para su monitoreo y evaluación, así como recomendaciones de otras políticas costo-efectivas como la regulación de la publicidad de alimentos no saludables dirigido a la niñez y adolescencia, entre otros, para la prevención de las ENT y la creación de ambientes y sistemas alimentarios más saludables y sostenibles(AU)

The Latin American region has been a pioneer in the implementation of a front- of-pack warning labeling system (FOPWL), which has demonstrated its efficacy and effectiveness in correctly identifying when a product contains excessive amounts of nutrients associated with Non-Communicable Diseases (NCDs). However, countries of the Central American Integration System (SICA); which includes Belize, Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua, Panama and the Dominican Republic, have no adopted it. For this reason, the Institute of Nutrition of Central America and Panama convened a group of experts from academia and civil society with the aim of establishing an evidence-based technical position, in relation to front-of-pack labelling for critical nutrients of pre-packaged foods and beverages in the Central American region. Specific evidence from the SICA region demonstrating the superiority of FOPWL over other labels such as the Guideline Daily Amount (GDA), the traffic light and Nutriscore to select healthier choices is presented. Within the framework of children's and consumer rights, arguments are provided, and a call is made to governments for the prompt adoption of FOPWL as a cost-effective policy for the prevention of NCDs. In addition, recommendations for its monitoring and evaluation are provided, as well as recommendations for other cost-effective policies such as the regulation of unhealthy food advertising aimed at children and adolescents, among others, for the prevention of NCDs and the creation ofhealthier and more sustainable environments and food systems(AU)

[Diet and body weight at the beginning of the COVID-19 pandemic in Mexico]. / Alimentación y peso corporal al inicio de la pandemia por COVID-19 en México.

Background: Weight changes in adults have strong repercussions on people's health status. During the COVID-19 pandemic, these changes could be more evident due to the mandatory confinement, as well as eating habits and lifestyle. In this study, changes in diet and body weight in Mexican population at the beginning of COVID-19 lockdown period (weeks 4-7) were evaluated using an online survey. Objective: To identify the characteristics of the diet and the perceived change in body weight at the beginning of the COVID-19 pandemic in Mexico. Material and methods: Descriptive, cross-sectional study of 1281 people over 18 years of age, electronic survey in weeks 4-7 of confinement with sociodemographic data, food consumption and perception of body weight. Results: The change in food consumption was 53.9%, finding differences according to gender in beverages (carbonated, juices, alcoholic), coffee/tea, fruits, legumes (p < 0.05). The perception of body weight increases by 3.4 (increased) and 2.1 (lowered) times more than the risk of change in diet. Conclusions: The dietary differences refer to a tendency to the type of food consumed, mainly sugary drinks, with the perception of changes in positive body weight in women.

Introducción: los cambios de peso corporal tienen fuertes repercusiones en el estado de salud de las personas. Durante la pandemia, estos cambios podrían verse más pronunciados debido al confinamiento obligatorio, así como a los malos hábitos alimentarios y al estilo de vida. En este estudio se examinaron los cambios en la alimentación y el peso corporal en población mexicana durante el inicio de la pandemia por COVID-19 (semanas 4-7 de confinamiento) mediante una encuesta en línea. Objetivo: identificar las características de la alimentación y el cambio percibido del peso corporal al inicio de la pandemia por COVID-19 en México. Material y métodos: estudio descriptivo, transversal, de 1281 personas mayores de 18 años, mediante encuesta electrónica en las semanas 4-7 de confinamiento, con datos sociodemográficos, consumo alimentario y percepción del peso corporal. Resultados: el cambio de consumo de alimentos fue del 53.9%, encontrando diferencias según sexo en bebidas (carbonatadas, jugos, alcohólicas), café/té, frutas, leguminosas (p < 0.05). La percepción del peso corporal incrementó en 3.4 (subieron) y 2.1 (bajaron) veces más el riesgo de cambio en la alimentación. Conclusiones: las diferencias alimentarias refieren una tendencia al tipo de alimentos que consumen, principalmente bebidas ricas en azúcares, con percepción de cambios en el peso corporal positivo en mujeres.

Metabolomics of head and neck cancer in biofluids: an integrative systematic review.

INTRODUCTION: Head and neck cancer (HNC) is the fifth most common cancer globally. Diagnosis at early stages are critical to reduce mortality and improve functional and esthetic outcomes associated with HNC. Metabolomics is a promising approach for discovery of biomarkers and metabolic pathways for risk assessment and early detection of HNC. OBJECTIVES: To summarize and consolidate the available evidence on metabolomics and HNC in plasma/serum, saliva, and urine. METHODS: A systematic search of experimental research was executed using PubMed and Web of Science. Available data on areas under the curve was extracted. Metabolic pathway enrichment analysis were performed to identify metabolic pathways altered in HNC. Fifty-four studies were eligible for data extraction (33 performed in plasma/serum, 15 in saliva and 6 in urine). RESULTS: Metabolites with high discriminatory performance for detection of HNC included single metabolites and combination panels of several lysoPCs, pyroglutamate, glutamic acid, glucose, tartronic acid, arachidonic acid, norvaline, linoleic acid, propionate, acetone, acetate, choline, glutamate and others. The glucose-alanine cycle and the urea cycle were the most altered pathways in HNC, among other pathways (i.e. gluconeogenesis, glycine and serine metabolism, alanine metabolism, etc.). Specific metabolites that can potentially serve as complementary less- or non-invasive biomarkers, as well as metabolic pathways integrating the data from the available studies, are presented. CONCLUSION: The present work highlights utility of metabolite-based biomarkers for risk assessment, early detection, and prognostication of HNC, as well as facilitates incorporation of available metabolomics studies into multi-omics data integration and big data analytics for personalized health.

Malnutrición e inadecuados hábitos de alimentación en bomberos de Panamá

La malnutrición por exceso es un problema de salud pública en Panamá. En bomberos, la malnutrición tiene graves implicaciones en la salud. El objetivo del presente estudio fue evaluar el estado nutricional, los hábitos alimentarios y el riesgo cardiovascular de unidades del Benemérito Cuerpo de Bomberos de la Región de Panamá Oeste en Panamá. Se realizó un estudio descriptivo y transversal de marzo a diciembre 2022. Para la recopilación de hábitos alimentarios se utilizó el formulario de frecuencia de consumo. Para la evaluación nutricional se midió peso, talla y circunferencia de la cintura. El riesgo cardiovascular fue estimado a partir de la razón cintura-altura (WHtR, por su acrónimo en inglés). Se evaluaron 100 participantes (79% son hombres) con edad entre 18 a 60 años. El exceso de peso se observó en el 88%, la obesidad en el 58%. El 97% consume frituras y 94% consume bebidas azucaradas. Solo el 20% y 16% consume vegetales y frutas diariamente. El 51% presenta riesgo cardiovascular por WHtR, siendo 39.2% en hombres y 95% en mujeres (p= 0.000). Se observa una alta proporción de exceso de peso, obesidad, obesidad abdominal y riesgo cardiovascular entre los bomberos evaluados. Bajo consumo de frutas y vegetales junto con un alto consumo de bebidas azucaradas y frituras. Es necesario implementar programas de prevención y control de la obesidad, así como brindar educación en alimentación y nutrición para abordar estos problemas de salud.

Malnutrition is a public health problem in Panama. In firefighters, malnutrition has serious health implications. We aim to evaluate the nutritional status, eating habits, and cardiovascular risk of units of the Fire Department of the West Panama Region in Panama. A descriptive and cross-sectional study was carried out from March to December 2022. For the collection of eating habits, a food frequency questionnaire was used. Weight, height, and waist circumference were used for the nutritional status evaluation. Cardiovascular risk was estimated from the waist-height ratio (WHtR). 100 participants (79% are men) aged between 18 and 60 years were evaluated. Excess weight was observed in 88%, and obesity in 58%. Cardiovascular risk by WHtR was presented in 51%, 39.2% of males, and 95% of females (p= 0.000). 97% consume fried foods and 94% consume sugary drinks. Only 20% and 16% consume vegetables and fruits daily. A high proportion of excess weight, obesity, abdominal obesity, and cardiovascular risk among the evaluated firefighters was observed. Low consumption of fruits and vegetables along with a high consumption of sugary drinks and fried foods. It is necessary to implement obesity prevention and control programs, as well as provide food and nutrition education to address these health problems.

Beneficios de la estimulación temprana en la prevención de alteraciones del neurodesarrollo en los primeros mil días: una revisión narrativa

Las alteraciones del neurodesarrollo en la primera infancia tienen una alta prevalencia a nivel mundial, representando un desafío para los especialistas porque deben lograr minimizar alteraciones en el niño desde la etapa prenatal. El objetivo de esta revisión es realizar un análisis narrativo de la evidencia disponible sobre el neurodesarrollo y el impacto positivo que tiene la estimulación temprana, particularmente durante los primeros mil días de vida, en la prevención de alteraciones del neurodesarrollo. Existen diversas pruebas estandarizadas de cribado del desarrollo infantil, para identificar posibles signos de alarma en el neurodesarrollo como la BINS, PRUNAPE, ASQ-3, Test de Denver, entre otras. Una de las alternativas de tratamientos no invasivos para tratar y prevenir alteraciones en el niño es la estimulación temprana. A través de la intervención integral en el niño se logra adquirir, compensar y/o potencializar las habilidades del neurodesarrollo; dando como resultado un ser adaptado al medio que lo rodea. Es importante diseñar y validar una guía integral para la vigilancia del neurodesarrollo infantil, desde la etapa prenatal para la prevención de alteraciones o evitar secuelas en el niño; así como diseñar políticas públicas que promuevan una adecuada infancia.  (provisto por Infomedic International)

Neurodevelopmental disorders in early childhood have a high prevalence worldwide, which represents a challenge for specialists because they must manage it to minimize alterations in children from the prenatal stage. The objective of this review is to carry out a narrative analysis of the available evidence on neurodevelopment and its positive impact that early stimulation, particularly during the first thousand days of life, has on the prevention of neurodevelopmental disorders. There are various child development standardized screening tests to identify possible neurodevelopmental alarm signs, such as the EDI, the Bayley, or the M-CHAT checklist. One of the non-invasive treatment alternatives to treat and prevent alterations in the child is early stimulation. Through comprehensive intervention in the child, it is possible to acquire, compensate and/or enhance neurodevelopmental skills, resulting in a being adapted to the environment that surrounds them. In conclusion, it is important to design and validate a comprehensive guide for monitoring child neurodevelopment, from the prenatal stage to prevent alterations or avoid sequelae in the child and public policies that promote an adequate childhood.

Ultra-processed food and homemade fried food consumption is associated with overweight/obesity in Latin American university students during COVID-19.

OBJECTIVE: We estimated the association between the consumption of select ultra-processed food (UPF), homemade fried food and overweight/obesity in Latin American university undergraduate students during the COVID-19 pandemic. METHODS: We conducted an analytical cross-sectional study. 4539 university students (73.6% female, mean age 22.5 ± 4.4) from 10 Latin American countries completed a self-administered online survey. UPF eating habits and homemade fried food were measured according to a validated survey. Height and body weight were self-reported. Body mass index (BMI) was calculated. A BMI ≥25 kg/m2 was categorized as overweight/obesity. Ordinal logistic regression models were applied. RESULTS: Snacks (36.2%) and homemade fried food (30.2%) had a higher prevalence of consumption than sugary drinks (22.5%) and fast food (7.2%). The greatest strength of association was found between fast food consumption [odds ratio (OR) = 2.16; 95% confidence interval (CI): 1.63-2.85], sugary drinks [OR = 2.05; CI: 1.63-2.59] and homemade fried food [OR = 1.46; CI: 1.16-1.85] with overweight/obesity. CONCLUSION: Latin American university undergraduates present risky eating behaviors associated with overweight and obesity. Effective policies to promote healthy eating should be incorporated and issued from universities to reduce the consumption of UPF and promote homemade, healthier and more natural food.

Nivel de conocimiento sobre nutrición y su asociación con las prácticas alimentarias y la obesidad entre estudiantes universitarios

Introducción: La literatura sobre el impacto de la educación alimentaria y nutricional de estudiantes universitarios en las prácticas alimentarias es heterogénea. Estudios han informado de que la educación alimentaria y nutricional puede cambiar los hábitos alimentarios y las elecciones alimentarias mientras que otros no encontraron asociación. Objetivo: Determinar la relación entre el conocimiento nutricional, las prácticas alimentarias y la obesidad en estudiantes universitarios nicaragüenses. Métodos: Estudio de corte transversal analítico que utilizó una muestra de 914 estudiantes universitarios de la ciudad de León en Nicaragua. Se midió el índice de masa corporal a través del peso y la estatura y el nivel de conocimiento nutricional. Las prácticas alimentarias fueron medidas con cuestionarios validados con moderadas modificaciones en base al contexto del país. Los datos fueron analizados mediante ANOVA de una vía, chi-cuadrado, prueba t de Student y regresión lineal. Resultados: Se encontró un bajo nivel de conocimiento nutricional y alta prevalencia de exceso de peso. El conocimiento nutricional de los estudiantes universitarios está asociado positivamente con las prácticas alimentarias. Sin embargo, aunque se tenga un máximo de conocimiento no significa un puntaje máximo de diversidad alimentaria. Asimismo, se reportó que las mujeres tienen una diversidad alimentaria ligeramente mayor a los hombres, pero mayor es la diversidad en el grupo que realizan actividad física y aquellos que tienen bajo peso. Por su parte, el conocimiento nutricional está asociado negativamente con el sobrepeso y la obesidad. Conclusión: se comprueba la hipótesis del impacto positivo del conocimiento nutricional en las prácticas alimentarias y la obesidad.

Background: The literature on the impact of food and nutrition education of university students on eating practices is heterogeneous. Studies have revealed that food and nutrition education can change eating habits and choices while others found no association. Objective: Determine the relationship between nutrition knowledge, eating practices, and obesity in Nicaraguan university students. Methods: Analytical cross-sectional study using a sample of 914 university students from the city of León in Nicaragua. The Body Mass Index (BMI) was calculated considering both values of weight and height, and the level of nutrition knowledge and eating practices were measured with validated questionnaires with moderate modifications based on the country context. The data were analyzed using one-way ANOVA, Chi-Square, Student's T-test, and linear regression. Results: A low level of nutrition knowledge and a high prevalence of overweight were found. The nutrition knowledge of university students is positively associated with eating practices. However, even if there is a high degree of nutrition knowledge, it does not mean there is a high dietary diversity score (DDS). Similarly, it was revealed that women have slightly greater dietary diversity scores than men, but greater dietary diversity scores in the group that performs physical activity and those who are underweight. On the other hand, nutrition knowledge is negatively associated with overweight and obesity. Conclusion: the hypothesis of the positive impact of nutrition knowledge on eating practices and obesity is tested.

Asociación entre consumo de alcohol y exceso de peso entre estudiantes universitarios de América Latina

Introducción: El sobrepeso y la obesidad son problemas de salud pública de nivel mundial. Si bien existe información respecto al consumo de alcohol en estudiantes universitarios durante la pandemia, pocos autores han señalado la asociación entre este hábito y el exceso de peso en esta población. El objetivo fue determinar la asociación entre el consumo de alcohol y el exceso de peso en estudiantes universitarios de 10 países de Latinoamérica durante la pandemia por COVID-19. Metodología: Se realizó un estudio transversal y multicéntrico con 4.539 estudiantes universitarios matriculados en diez países de América Latina. Para la valoración del consumo de alcohol se utilizó la pregunta ¿Consumes bebidas alcohólicas? (1 porción 1 vaso de 200 ml). El índice de masa corporal (IMC) se determinó a partir del peso y la altura auto informado. Para determinar si el exceso de peso (IMC ≥25 kg/m2) estaba asociado con el consumo de alcohol, se utilizó un análisis de regresión logística, ajustado por edad, sexo, año de estudio, nivel socioeconómico, actividad física y tabaquismo. Resultados: Entre los estudiantes con estado nutricional normal, un 59,6% no consumía alcohol, mientras entre los que presentaban un exceso de peso era un 55,1%. Los estudiantes que consumían 2 o más porciones de alcohol al día tenían 2,18 veces más riesgo de tener exceso de peso (OR: 2.18 [95% IC: 1,26 a 3,77]), comparado con aquellos que no consumían alcohol. Conclusión: Se observó que aquellos estudiantes que consumieron más alcohol tuvieron más probabilidades de tener exceso de peso.

Introduction: Overweight and obesity are public health problems worldwide. Alcoholic beverages could increase total energy intake causing an increase in body weight. However, few authors have pointed out the association between this habit and excess weight in this population. The objective of this study was to determine the association between alcohol consumption and excess weight in university students from 10 Latin American countries during the COVID-19 pandemic. Methodology: A cross-sectional and multicenter study was carried out with 4,539 university students enrolled in ten Latin American countries. To assess alcohol consumption, the question Do you consume alcoholic beverages? (1 portion 1 glass of 200 ml). Body mass index (BMI) kg/m2 was determined from self-reported weight and height. To determine if excess weight was associated with alcohol consumption, a logistic regression analysis was used, adjusted for age, sex, year of study, socioeconomic level, physical activity, and smoking. Results: Among students with normal nutritional status, 59.6% did not consume alcohol, while among those with a BMI ≥25 kg/m2 it was 55.1%. Students who consumed 2 or more servings of alcohol per day had a 2.18 times greater risk of being overweight (OR: 2.18 [95% CI: 1.26 to 3.77]), compared with those who did not consume alcohol. Conclusion: It was observed that those students who consumed more alcohol were more likely to be overweight.

Prevalence of Anemia and Iron Deficiency in Women of Reproductive Age in Cuba and Associated Factors.

This study aims to evaluate the prevalence of anemia and iron deficiency in women of reproductive age and the association with inflammation, global overweight, adiposity, and menorrhagia. A sample design of women of reproductive age from the Eastern, Central, and Havana Regions was carried out. Biochemical determinations of hemoglobin, serum ferritin, soluble transferrin receptors, leukocytes, C-reactive protein, alpha-1 acid glycoprotein, and homocysteine were performed. Serum ferritin was also adjusted by inflammation. Nutritional status was assessed, and menstrual characteristics were collected by survey. A total of 742 women were studied. The prevalence of anemia was 21.4%, iron storage deficiency at 16.0%, and erythropoietic dysfunction at 5.4%, with inflammation at 47.0% and elevated homocysteine at 18.6%. Global overweight was 46.2% and increased adiposity at 58.4%. Anemia is associated with iron deposition deficiency (OR = 3.023 (1.816-5.033)) and with erythropoietic deficiency (OR = 5.62 (3.03-10.39)), but not with inflammation, global overweight, and adiposity. Global overweight was found to be associated with inflammation (OR = 2.23 (1.41-3.53)). Anemia was associated with heavy menstrual bleeding (OR = 1.92 (1.34-2.76)). Homocysteine was associated with inflammation (OR = 2.05 (1.08-3.90)), but not with anemia. In conclusion, anemia in Cuba is classified as a moderate public health problem, but not iron deficiency. A high prevalence of overweight and obesity was found, associated with inflammation, but not with anemia or iron deficiency. Heavy menstrual bleeding is a factor associated with anemia.

Healthy Lifestyle Habits in Latin American University Students during COVID-19 Pandemic: A Multi-Center Study.

Background: Deterioration in the health-related quality of life (HRQoL) and healthy eating behavior due to the effect of COVID-19 lockdown has been reported. The aim of this study was to associate eating habits and HRQoL with physical activity behavior in Latin American university students during COVID-19 pandemic.Methods: Measured 4,859 university students with a mean age of 22.4 years and they were mostly female (73.7%) from 10 Latin American countries (Argentina, Chile, Colombia, Costa Rica, Ecuador, Guatemala, Mexico, Panama, Paraguay and, Peru). Eating habits were measured using a survey validated with other university students, HRQoL was assessments using the short version of the World Health Organization (WHOQOL-BREF) scale and physical activity behavior with a dicotomous question based on the international recommendations for physical activity.Results: There is a higher complaince for all the international recommendations for healthy foods intake in the physically active group of students (p < 0.01), with the exception of alcohol and salt. In addition, physically active students presented a significantly higher HRQoL (p < 0.001) in all the dimensions analyzed when compared to physically inactive students.Conclusions: Latin American university students who are physically active are more likely to have a healthier eating behavior and a lower risk of a decreased HRQoL during COVID-19 pandemic.

Bodyweight change and its association with food and beverage consumption at the beginning COVID-19 confinement.

OBJECTIVES: SARS-CoV-2, a newly identified coronavirus responsible for the COVID-19 pandemic, has challenged health services and profoundly impacted people's lifestyles. The objective of the present study was to evaluate the effect of confinement during the COVID-19 pandemic on food consumption patterns and body weight in adults from 12 Ibero-American countries. METHODS: Multicentric, cross-sectional study. Data was collected using an online survey disseminated by social networks. The sample included 10 552 people from Spain and 11 Latin American countries who were selected by snowball sampling. RESULTS: While 38.50% of the sample reported weight gain, 16.90% reported weight lost. Weight change was associated with sex, age, country of residence, and education level. People who were not confined more often reported having maintained their weight in comparison to people who were confined. All Latin American countries showed an increased consumption of sweetened drinks, pastry products, fried foods, and alcoholic beverages during confinement. Consumption of eggs and dairy products was independent from body weight change. People who consumed more fruits and vegetables during confinement more often reported having lost weight. In contrast, body weight gain during confinement was associated with increased intake of sugary drinks, baked goods and pastries, pizza, fried foods, and alcoholic beverages. CONCLUSION: During COVID-19 confinement, the Latin American countries included in this study showed a change in their consumption patterns toward less healthy diets, which in turn was associated with an increase in the body weight of their population.

Quality of the diet during the COVID-19 pandemic in 11 Latin-American countries.

BACKGROUND AND OBJECTIVES: The confinement by COVID-19 has affected the food chain and environments, which added to factors such as anxiety, frustration, fear and stress have modified the quality of the diet in the population around the world. The purpose of this study was to explore diet quality during the COVID-19 pandemic in 11 Latin American countries. METHODOLOGY: Multicentric, cross-sectional study. An online survey was applied to residents of 11 Latin-American countries, during April and May 2020, when confinement was mandatory. Diet quality was evaluated using a validated questionnaire. RESULT: 10,573 people participated in the study. The quality of the food by country shows that Colombia presented the best quality, while Chile and Paraguay presented the lowest. When comparing the overall results of diet quality by gender, schooling and age, women, people with more schooling and people under 30 years of age, presented better diet quality. The regression model showed that the variables associated with diet quality were: age (df = 3, F = 4. 57, p < 0.001), sex (df = 1, F = 131.01, p < 0.001), level of education (df = 1, F = 38.29, p < 0.001), perception of weight change (df = 2, F = 135.31, p < 0.001), basis services (df = 1, F = 8.63, p = 0.003), and quarantine (df = 1, F = 12.14, p = 0.001). CONCLUSION: It is necessary for governments to intervene to reverse these indicators, considering that inadequate feeding favors the appearance of no communicable diseases, which favor a higher risk of infection and worse prognosis with COVID-19.

Caracterización de patrones alimentarios al inicio de la pandemia por covid 19 en chile / Characterization of the dietary profile of the old adults in Ibero-american during of pandemic by COVID 19

Objetivo: Caracterizar el perfil alimentario de las Personas Mayores de Iberoamérica en tiempos de pandemia por COVID 19.Material y métodos: Estudio multicéntrico en 12 países de Iberoamérica, se aplicó una encuesta en línea que incluyó preguntas sociodemográficas y un cuestionario de Ingesta de Alimentos que incluyo la frecuencia de consumo para verduras, bebidas azucaradas, legumbres, lácteos y porción de los alimentos.Resultados: La muestra quedó conformada por 624 participantes, 72,1% (n= 450) de mujeres. El 54,7% de mujeres no consume bebidas azucaradas, en cambio en hombres un 54% consume al menos un vaso al día (p=0,012). El 35,6% de hombres consumieron ≥3 por semana legumbres versus el 23% mujeres (p=0,020). El 37,3% de las mujeres consumen ≥2 porciones diarias de lácteos, en hombres solo un 28,1% (p= 0,030). Las mujeres presentan un mayor consumo de verduras (44,7%, n= 201) respecto de los hombres (28,7%), (p=0,001). El 17,4% de la muestra total aumentó el tamaño de la porción de alimentos, sin do mayor en mujeres (p=0.005).Conclusión: Las mujeres presentan hábitos alimentarios más saludables que los hombres en base a frutas, verduras, por otra parte, la variación del tamaño se observa un incremento en especial en mujeres lo que puede relacionarse con el aumento de la obesidad.(AU)

Body weight in relation to hours of sleep, and physical activity in Latin American university students during the Covid-19 pandemic.

Introduction: Short sleep, physical inactivity, and being locked up are risk factors for weight gain. Objective: We evaluated weight gain according to sex, age, hours of sleep and physical activity in university students from 10 Latin American countries during the COVID-19 pandemic. Methods: Cross-sectional and multicenter study (n = 4880). Results: The average age was 22.5 ± 4.4 years. 60.2% were currently locked up. 73.6% were women, 48.2% increased their body weight, 66% reported insufficient sleep hours, and 65.9% were inactive. Women gained more weight than men (73.2%) and younger students gained more weight (85.1%). Those who had insufficient sleep hours gained most weight (67.6%). Inactive participants gained most weight (74.7%). Students who have insufficient sleep are 21% more likely to have changes in body weight compared to students who have optimal sleep. Conclusion: The increase in body weight and its risk factors during confinement should be considered as emerging from public health.

Psychological factors of diet quality among rural populations of Latin America during the COVID-19 pandemic: a cross-sectional study.

INTRODUCTION: This study aimed to determine the relationship between symptoms of anxiety and/or anhedonia (inability to feel pleasure) and diet quality during confinement due to COVID-19 in rural populations in Latin America. METHODS: This was a multicentric, cross-sectional study. An online survey was applied, which included the Beck Anxiety Inventory, Snaith-Hamilton Pleasure Scale for assessing the presence of anhedonia, the Food Intake Questionnaire and sociodemographic questions. RESULTS: The study included 10 552 people from 11 countries; 708 participants were living in rural areas. More than half of the participants were quarantined at the time of the survey. Diet quality was inversely associated with anhedonia (p<0.001) and anxiety (p=0.003). In addition, a healthier diet was associated with being female (p=0.030), having a higher level of education (p=0.008) and country of residence (p=0.001). CONCLUSION: Among the rural population during the COVID pandemic, this study found a worse diet quality was associated with symptoms of anhedonia and anxiety, as well as lower level of education and being male. Proposals to improve the quality of the diet could include interventions aimed at people's mental health.
