RESUMO
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.

INTRODUCTION: high-calorie and sugar-sweetened food is considered more pleasant food. People with anhedonia symptoms have difficulties experiencing pleasure in daily activities. However, is still unclear if anhedonia symptomatology increases palatable food consumption in the Chilean Adults sample. OBJECTIVE: to explore food networks in the Chilean Adults sample and in people with anhedonia symptom. METHODS: the sample was recruited through digital platforms. Pregnant or lactating women and subjects under pharmacological treatment or psychotherapy were excluded. A total of 1242 subjects, 76.6% women, with a mean age of 30.7 (SD 9.3) and who were highly educated, participated in the study. Data were collected through an online survey. A questionnaire on food consumption based on daily and weekly frequency was used, as well as the Snaith-Hamilton Pleasure Scale to measure anhedonia symptoms. We employed the Gaussian graph model (GGM) to analyze food consumption as networks. We started with the total sample, and then we repeated the analysis on a subsample with anhedonia symptoms, and next on a subsample with exclusively food-related anhedonia. RESULTS: in the total sample, a positive and strong relationship was observed between fruits and vegetables, as well as a negative association with the triad of sugar-sweetened beverages, fast food, and fried food. The network in anhedonic subjects shows that "pasta, rice & potatoes" and "bread" have a stronger association and a more central place in the network compared those without anhedonia symptoms. CONCLUSIONS: Subjects with anhedonia symptoms have a more central consumption of foods with a high or medium glycemic index compared to subjects without anhedonia symptoms, which could trigger the development of chronic diet-related diseases.
RESUMO
AIM: The main objective of this study was to analyze the change in physical activity, quality of diet, and weight upon admission to higher education and at one-year follow-up in Chilean university students. MATERIALS AND METHODS: 376 Chilean university students were prospectively recruited. All participants were assessed at bas eline and one-year follow-up. Sociodemographics and other co-variables were described. Physical activity, healthy eating behavior, height, weight, and body mass index (BMI) were assessed using the Global Physical Activity Questionnaire (GPAQ), and quality of diet (with Healthy Eating Index), SECA 213 stadiometer and TANITA HD-351, respectively. RESULTS: At the one-year follow-up, high-intensity METs (Metabolic equivalents) decreased by 147.9 (95% CI: 79.5 to 216; p = 0.000), moderate-intensity METs decreased by 85.0 (95% CI: 52.2 to 117.7; p = 0.000), sedentary behavior increased by 45.0 min/week (95% CI: 54.6 to 35.4; p = 0.000), total METs decreased by 793.6 (95% CI: 613.0 to 974.1; p = 0.000), HEI decreased by 45.4 points (95% CI: 48.5 to 82.1; p = 0.000), weight increased by 5.9 kg (95% CI: 3.5 to 6.3; p = 0.002), and BMI increased by 2.8 kg/m2 (95% CI: 2.7 to 3.2; p = 0.000). The correlation between total METs and the HEI was r = 0.21 (p = 0.013). CONCLUSIONS: There are statistically significant differences at one-year follow-up in Chilean university students in decreased physical activity, impaired healthy eating behavior, and increased weight and BMI.

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.

The current epidemic of COVID-19 has gained attention and highlighted the need for a better understanding of the population's mental health. Diet has been identified as an environmental determinant of mental health. In this regard, it has been suggested that the consumption of palatable foods represents a strategy to mitigate negative emotions, such as anxiety. This study aimed to evaluate the association between symptoms of anxiety and/or anhedonia to food consumption patterns during the period of COVID-19 quarantine in Chile. We conducted a cross-sectional study with non-randomized sampling via an online survey. A total of 1725 responses were collected. Each person self-answered the Beck Anxiety Inventory, Snaith-Hamilton Pleasure Scale for anhedonia, the Food Intake Questionnaire, and questions regarding type and duration of lockdown, as well as body weight and food serving variation. Significant correlations were observed between fried food consumption and self-reported body weight. The subjects who consumed fried food three times a week, had higher weight (63.5%) (χ2 = 48.5 and p < 0.001). Those who ate one and two or more pastries on a week had 1.41 and 1.49, respectively higher odds of reporting increased body weight. We found a relationship anxiety level and sugar-sweetened beverages level (χ2 = 25.5; p 0.013), fast food intake (χ2 = 63.4; p < 0.001), and pastry consumption (χ2 = 37.7; p < 0.001). In conclusion, it is important to monitor the evolution of these findings since they could represent a risk of increased health problems in the future post-lockdown period.

A Mediterranean diet (MedDiet) has emerged as a crucial dietary choice, not only in attenuating various adolescents' metabolic health issues but it has also been associated with improved cognitive and academic achievement. However, few studies have established patterns of food consumption linked to both cognitive and academic achievement in adolescents living in a developing country with non-Mediterranean-based food. Methods: This cross-sectional study included 1296 Chilean adolescents (50% girls) aged 10-14 years. The MedDiet Quality Index was used to assess adherence to the MedDiet in children and adolescents. Through cluster analysis, four distinct dietary patterns were identified: Western diet (WD = 4.3%); low fruit and vegetables, high-sugar diet (LFV-HSD = 28.2%); low fruit and vegetables, low-sugar diet (LFV-LSD = 42.2%); and the MedDiet (25.3%). A mixed-model analysis was conducted to compare these clusters and their relationships with cognitive and academic achievements. Principal component analysis was performed to identify four primary cognitive domains: working memory, cognitive flexibility, inhibitory control, and fluid reasoning. Academic achievement was determined with five school subjects (Language, English, Mathematics, Science, and History) and included the Academic-PISA score derived from the mean scores in Language, Mathematics, and Science. Results: A marked difference was observed between the four clusters, which was mainly related to the consumption of sugar, ultra-processed foods, fruits, and vegetables. According to cognitive performance, the MedDiet group showed higher performance across all domains than the LFV-HSD, LFV-LSD, and WD groups. Regarding academic achievement, the WD underperformed in all analyses compared to the other groups, while the MedDiet was the unique profile that achieved a positive difference in all academic subjects compared to the WD and LFV-HSD groups (p < 0.05). Conclusions: These findings suggest that higher adherence to Mediterranean-style-based patterns and better food quality choices are associated with improved cognitive and academic achievements.

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.

BACKGROUND: At hospital level, clinical nutritionists play a fundamental role in health recovery, contributing to shorter hospital stays and addressing hospital malnutrition. However, in Latin America no studies have been conducted on the activities of the nutritionist and the factors influencing their performance. AIMS: to describe the activities of the clinical nutritionist in public and private hospital settings in Latin America and to determine the factors associated with disciplinary practice. METHODS: A cross-sectional analytical, quantitative study was conducted. Participants consisted of hospital nutritionists from 13 Latin American countries who had participated in a previously validated online survey on the activities performed during their daily work, obtaining a Professional Activities Score (PAS). RESULTS: 1222 nutritionists participated. Of the activities associated with the professional role, the only ones who reached over 75 % of execution were: performing nutritional intervention; performing nutritional assessment and diagnosis; providing counseling and dietary prescription; developing nutritional care plans for patients with nutritional problems; and performing the monitoring and evaluation of results of priority patients. The least frequent activities were: university teaching and collaborating in research. Regarding the reasons for not performing activities: 34.0 % reported not being included in the activities, 24.5 % mentioned lack of time, and 13.6 % indicated that the activities were conducted by another professional. Variables positively associated with an increase in the PAS were: having spent more years exercising the profession (Beta: 0.028, 95 % CI: 0.004; 0.051), and having a greater number of specialties (4 or more, Beta: 2.294, 95 % CI: 1.031; 3.557). Working in lower-complexity facilities (Low: Beta: -1.037, 95 % CI: -1.443; -0.630), and having more reasons for not performing the activities (3 or more: Beta: -3.105, 95 % CI: -4.111; -2.099) were inversely associated. From the sample, 1.8 % held a doctorate in clinical nutrition, 43.9 % had a specialty, and 64.4 % had a diploma or postgraduate degree in clinical nutrition. CONCLUSION: None of the activities related to the nutritionist work was performed on a 100 % basis. In Latin America, Ministries of Health should standardize and regulate the functions of the clinical nutritionist, as well as quantifying understaffing and proposing solutions to alleviate the shortage of these professionals, acknowledging the positive impact that they have on the recovery of hospital patients.

The aim of the present study was to compare the frequency of consumption, access to purchase, and type of preparations with pulses among people who eat a vegetarian/vegan or non-vegetarian diet during the COVID-19 pandemic.Cross-sectional surveys were distributed using different digital platforms and social networks. We investigated the frequency of consumption, access to purchase any type of preparations. Descriptive analyses were performed. Differences between the types of diet were tested by Chi-squared statistics.A total of 3339 adults participated in the survey in March 2021, 80% of the total participants were females; 13.6% were vegetarian or vegan (VV). The consumption of pulses increased by 25% among non-vegetarians and 54.5% in VV (p by 25% among non-vegetarians and 54.5% in VV (vey in March 2021, 80% of the total participants were females; 13.6% were vegetarian or vegan (VV). The consumption of pulses preparations. Descriptive analyses were performfood with high satiating power, when compared with the opinions of non-vegetarians (p ood with high satiating power, when cconsumption of pulses were observed in less than 30% of the respondents, but the percentage was lower among VV, the most common negative beliefs are "They are difficult to prepare" and "My family does not like them." Food preparations including pulses are more diverse among VV, and consumption being significantly higher in the 10 alternatives of preparations included in the study.These results highlight the importance of identifying the knowledge, practices, frequency, and preferences of consumption of legumes in the population to stimulate their consumption. Although we observed an increase in the consumption of legumes among those in the sample, the VV group showed a higher frequency of consumption, consumption of different types of legumes and varied preparation, and greater knowledge about the beneficial properties of legumes.

BACKGROUND: In Chile, the consumption of legumes at least two times per week is promoted. However, there is a low consumption of legumes. Therefore, our objective is to describe legume consumption in two different seasonal periods. METHODS: Serial cross-sectional study: surveys were distributed during summer and winter using different digital platforms. Frequency of consumption, purchase access, and preparation type were investigated. RESULTS: In total, 3280 adults were surveyed in summer and 3339 in winter. The mean age was 33 years. Totals of 97.7% and 97.5% of the population reported consuming legumes in both periods; consumption increased to 3 times per week during winter. In both periods, the main reason for their preference is that they are delicious and nutritious, followed by their use as a meat substitute; the main barriers to their consumption in both periods are that they are expensive (29% in summer and 27.8% in winter) and difficult to prepare. CONCLUSION: A good consumption of legumes was observed, but with a higher frequency of consumption during winter, with an intake of ≥1 per day; additionally, differences were found in purchases according to season, although no differences were found in the method of preparation.

Atherosclerosis, chronic non-communicable diseases, and metabolic syndrome are highly interconnected and collectively contribute to global health concerns that reduce life expectancy and quality of life. These conditions arise from multiple risk factors, including inflammation, insulin resistance, impaired blood lipid profile, endothelial dysfunction, and increased cardiovascular risk. Adopting a plant-based diet has gained popularity as a viable alternative to promote health and mitigate the incidence of, and risk factors associated with, these three health conditions. Understanding the potential benefits of a plant-based diet for human health is crucial, particularly in the face of the rising prevalence of chronic diseases like diabetes, hypertension, dyslipidemia, atherosclerosis, and cancer. Thus, this review focused on the plausible advantages of consuming a type of food pattern for the prevention and/or treatment of chronic diseases, emphasizing the dietary aspects that contribute to these conditions and the evidence supporting the benefits of a plant-based diet for human health. To facilitate a more in-depth analysis, we present separate evidence for each of these three concepts, acknowledging their intrinsic connection while providing a specific focus on each one. This review underscores the potential of a plant-based diet to target the underlying causes of these chronic diseases and enhance health outcomes for individuals and populations.

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.

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.

A clinical nutritionist (CN) is a university-educated professional trained to perform preventive and recovery functions in the health of patients. The actions of these professionals, both worldwide and in Latin America, may face barriers and opportunities that require careful identification and examination. The main objective of this study is to identify the most important barriers and opportunities for the clinical nutritionist in 13 Latin American countries. A qualitative study was carried out; the initial phase involved conducting in-depth individual interviews with 89 informants, experienced CNs from 13 Latin American countries. After calculating the mean and standard deviation, we ranked the top 10 most frequently reported barriers by assigning a score ranging from 1 to 10. Additionally, 3 opportunities were identified with a lower score from 1 to 3. Means and standard deviation were calculated to sort the responses. Results: the most important barrier was the absence of public policies that regulate and/or monitor compliance with the staffing of CNs according to the number of hospital beds, while the most important opportunity was the advances in technology such as software, body analysis equipment and other tools used in Nutritional Care. The identified barriers can interfere with the professional performance of CNs and, moreover, make it difficult to monitor the good nutritional status of patients. It is recommended to consider the barriers identified in this study, as well as the opportunities, with a view to improving the quality of hospital services with an adequate supply of nutritionists.

A reduction in EPC (endothelial progenitor cell) number could explain the development and progression of atherosclerosis in the MetS (metabolic syndrome). Although much research in recent years has focused on the Mediterranean dietary pattern and the MetS, the effect of this diet with/without moderate-to-high-intensity endurance training on EPCs levels and CrF (cardiorespiratory fitness) remains unclear. In the present study, the objective was to assess the effect of a Mediterranean diet hypocaloric model with and without moderate-to-high-intensity endurance training on EPC number and CrF of MetS patients. Thus 45 MetS patients (50-66 years) were randomized to a 12-week intervention with the hypocaloric MeD (Mediterranean diet) or the MeDE (MeD plus moderate-to-high-intensity endurance training). Training included two weekly supervised sessions [80% MaxHR (maximum heart rate); leg and arm pedalling] and one at-home session (65-75% MaxHR; walking controlled by heart rate monitors). Changes in: (i) EPC number [CD34(+)KDR(+) (kinase insert domain-containing receptor)], (ii) CrF variables and (iii) MetS components and IRH (ischaemic reactive hyperaemia) were determined at the end of the study. A total of 40 subjects completed all 12 weeks of the study, with 20 in each group. The MeDE led to a greater increase in EPC numbers and CrF than did the MeD intervention (P ≤ 0.001). In addition, a positive correlation was observed between the increase in EPCs and fitness in the MeDE group (r=0.72; r(2)=0.52; P ≤ 0.001). Body weight loss, insulin sensitivity, TAGs (triacylglycerols) and blood pressure showed a greater decrease in the MeDE than MeD groups. Furthermore, IRH was only improved after the MeDE intervention. In conclusion, compliance with moderate-to-high-intensity endurance training enhances the positive effects of a model of MeD on the regenerative capacity of endothelium and on the fitness of MetS patients.

Background: Excess adipose tissue negatively influences bone health during childhood, affecting future bone fragility diseases such as osteoporosis. However, little is known about how adolescent appendicular skeletal muscle mass index (ASMI) may mediate the relation between fatness and bone mineral content (BMC). Methods: The sample comprised 1,296 adolescents (50% girls) aged 10-14. A principal component analysis was performed to obtain a factor made up of four fatness indicators (a) neck circumference, (b) kilograms of fat, (c) visceral fat area, and (d) waist-to-height ratio. BMC, kilograms of fat, visceral fat area, and appendicular skeletal muscle mass were obtained by a multi-frequency bioelectrical impedance analyzer. ASMI was calculated as the appendicular skeletal muscle mass divided by height squared (kg/m2). A mediation analysis was performed adjusting by age, sex, maturation, socioeconomic status, physical activity, and adolescents' body weight. We also explore differences by sex and nutritional status. Results: The fatness factor explained 71.5% of the proportion variance. Fatness was inversely associated with the ASMI and BMC, while the ASMI was positively related to BMC. Overall, the inverse relationship between fatness and BMC was partially mediated by the adolescents' ASMI (29.7%, indirect effect: B= -0.048, 95%CI -0.077 to -0.022), being higher in girls than in boys (32.9 vs. 29.2%). Besides, the mediation effect was higher in adolescents with normal body weight than with overweight-obese (37.6 vs 23.9%, respectively). Conclusions: This finding highlighted the relevance of promoting healthy habits to reduce fatness and improve muscle mass in adolescents. Moreover, this highlights the central role of ASMI mediating the inverse association between fatness and BMC in female and male adolescents. Public health strategies should promote bone health in childhood, reducing the incidence of early osteopenia and osteoporosis.
RESUMO
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.

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.

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.
RESUMO
Most worldwide causes of disease and death are strongly associated with dietary factors and the application of eating indexes has proved to be a useful tool to determine diet quality in populations. The aim of this study was to evaluate the diet quality in Chile through the application of the Alternate Healthy Eating Index 2010 (AHEI-2010). A representative sample (n = 879) of Chilean urban population aged 15â»65 years old from the Latin American Study of Nutrition and Health (Estudio Latinoamericano de Nutrición y Salud; ELANS) was used. Dietary intake data were obtained through two 24-hour food recalls and one beverage frequency questionnaire, which were used to calculate AHEI-2010 and its association with sociodemographic and anthropometric variables. In this Chilean sample, the AHEI-2010 score was 43.7 ± 7.8 points (mean ± SD). Trans fats and sodium intake were the highest scoring AHEI-2010 components whereas sugar-sweetened beverages and whole grains had the lowest score. Women, older subjects, and individuals in medium-high socioeconomic levels had significantly higher mean AHEI-2010 scores. No association was found between AHEI-2010 and body mass index (BMI), or nutritional status. Conclusions: Diet quality in the Chilean urban population aged 15â»65 years old is far from optimal. Thus, there is room for significant improvement of diet quality in Chile through design and implementation of public health policies, particularly in high-risk groups for chronic diseases.
