RESUMO

Objective: To understand the association of food insecurity with sociodemographic factors in a sample population in Latin America during the COVID-19 pandemic. Methods: This was a multicenter cross-sectional study conducted in 10 countries in Latin America using an online survey through various digital platforms from October 14, 2020 to February 15, 2021. Statistical analysis of data was performed by applying descriptive statistics, chi-square test, and logistic regression analysis. Results: Of a total of 6 357 surveys, 58.2% of respondents experienced food security, 29.3% were slightly food insecure, 9.2% were moderately food insecure, and 3.3% were severely food insecure. Concerning the association food insecurity and sociodemographic variables, there is a significant association in the variables studied, including area of residence, education level, occupation, number of persons in the household, household with children younger than 10 years of age, and socioeconomic level. Conclusions: These findings indicate that sociodemographic factors associated with food insecurity during the COVID-19 pandemic in Latin America were rural residence; complete and incomplete basic and secondary schooling; occupation (homemaker, unemployed, and self-employed); low, medium-low, and medium socioeconomic level; household with more than four persons; and household with children younger than 10 years of age.

[RESUMEN]. Objetivo. Determinar la asociación de la inseguridad alimentaria con factores sociodemográficos en una muestra de población de América Latina durante la pandemia de COVID-19. Métodos. Se llevó a cabo un estudio transversal multicéntrico en diez países de América Latina mediante una encuesta en línea a través de diversas plataformas digitales, entre el 14 de octubre del 2020 y el 15 de febrero del 2021. Se realizó un análisis estadístico de los datos usando procedimientos de estadística descriptiva, la prueba ji al cuadrado y un análisis de regresión logística. Resultados. En un total de 6 357 encuestas, el 58,2% de las personas encuestadas gozaba de seguridad ali- mentaria, el 29,3% tenía una inseguridad alimentaria leve, el 9,2% una inseguridad alimentaria moderada y el 3,3% una inseguridad alimentaria grave. Por lo que respecta a la asociación entre la inseguridad alimentaria y las variables sociodemográficas, hay una asociación significativa para algunas de las variables estudiadas, como la zona de residencia, el nivel de estudios, la actividad laboral, el número de personas en el hogar, el hogar con menores de 10 años y el nivel socioeconómico. Conclusiones. Estos resultados indican que los factores sociodemográficos asociados a la inseguridad alimentaria durante la pandemia de COVID-19 en América Latina fueron la residencia en zonas rurales; la edu- cación primaria y secundaria completa o no; la actividad laboral (trabajo doméstico, personas desempleadas y trabajadores autónomos); el nivel socioeconómico bajo, medio bajo, y medio; el hogar con más de cuatro personas; y el hogar con menores de 10 años.

RESUMO

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.

RESUMO

Introduction: Introduction: intermittent fasting plans propose to limit food intake during specific periods as nutritional therapeutic strategies to treat different metabolic conditions in various clinical entities. However, the heterogeneity between each context of intermittent fasting could generate different results in metabolic parameters. Objective: to evaluate the clinical application of intermittent fasting and to discern whether it offers advantages over other traditional strategies. Methods: structured questions were formulated (PICO), and the methodology followed the guidelines established by the PRISMA 2020 statement. The search was conducted in different databases (PubMed, Cochrane Library and Google Scholar). Results: we found 3,962 articles, of which 56 were finally included; 3,906 articles that did not directly or indirectly answer the structured questions were excluded. Conclusions: compared to conventional diets, the various AI schemes do not generate advantages or disadvantages in terms of weight loss and lipid profile, although in the alternate-day variant there are greater insulin reductions than those observed in the continuous energy restriction. The heterogeneity of the interventions, the populations studied, the comparators, the results, and the type of design make it impossible to extrapolate the effects found in all clinical scenarios and generalize the recommendations.


Introducción: Introducción: los esquemas de ayuno intermitente (AI) proponen limitar la ingestión de alimentos durante periodos específicos. Se han propuesto como estrategia dietoterapéutica para tratar distintas condiciones metabólicas en diversos padecimientos, sin embargo, la heterogeneidad entre cada contexto de ayuno intermitente pudiera generar diferentes resultados en parámetros metabólicos. Objetivo: evaluar la aplicación clínica del ayuno intermitente y discernir si ofrece ventajas sobre otras estrategias tradicionales. Métodos: se formularon preguntas estructuradas (PICO) y la metodología se apegó a las guías establecidas por la declaración PRISMA 2020. Se realizó una búsqueda de literatura científica en las plataformas de PubMed, Cochrane Library y Google Scholar. Resultados: se encontraron 3.962 artículos, de los cuales se incluyeron finalmente 56, eliminando 3.906 trabajos que no contestaban directa o indirectamente las preguntas estructuradas. Conclusiones: frente a las dietas convencionales, los diversos esquemas de AI no generan ventajas ni desventajas en cuanto a pérdida de peso o perfil lipídico, aunque en la variante a días alternos se producen mayores reducciones de insulina a las observadas en la restricción energética continua. La heterogeneidad de las intervenciones y poblaciones estudiadas, así como los comparadores, los desenlaces y el tipo de diseño imposibilitan extrapolar los efectos a todos los escenarios clínicos y generalizar las recomendaciones.

RESUMO

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)

RESUMO

Objective: Explore the association between compliance with recommended consumption (5-a-day) of fruits and vegetables (F&V) with sociodemographic factors of university students of Latin America. Subjects: We conducted an analytical cross-sectional study in which 4,880 university students from 10 Latin American countries completed a self-administered online survey. Methods: F&V consumption and other sociodemographic variables were measured according to a validated survey. Body mass index was self-reported. Ordinal logistic regression models were applied. Results: Regarding the consumption of F&V, 4.7% of men complied with the recommendation, while in women this value reached 7.7%. In the adjusted model, having a normal weight (OR= 0.59; 95% CI 0.44-0.7; p=<0.001), being female (OR= 0.67; 95% CI 0.49-0.89; p=<0.01), being enrolled in a health-related degree program (OR= 0,60; IC95% 0,45-0,78; p<0.001), having professional parents (OR= 0.75; 95% CI 0.60-0.95; p=<0.05) and practicing physical activity (OR= 0.34; 95% CI 0.27-0.42; p=<0.001) were associated with compliance to F&V consumption recommendations. In the analysis by country, physical activity was the variable most associated with F&V consumption. Conclusion: We observed a low consumption of F&V in university students. The variables associated with compliance to the F&V recommendation were being normal weight, female, being enrolled in a health-related degree program, having professional parents, and practicing physical activity, the latter being the most important variable.


Objetivo: Explorar la asociación de la frecuencia de cumplimiento de las recomendaciones de consumo (5 al día) de frutas y verduras (F&V) con factores sociodemográficos de estudiantes universitarios de América Latina. Metodología: Se realizó un estudio transversal analítico con 4.880 estudiantes universitarios de 10 países de América Latina, quienes completaron una encuesta en línea autoadministrada. Se midió el consumo de F&V y otras variables sociodemográficas según una encuesta previamente validada. El índice de masa corporal fue autoinformado. Se aplicaron modelos de regresión logística ordinal. Resultados: En cuanto al consumo de F&V, en los hombres el 4,7% cumple con la recomendación, mientras que en las mujeres este valor alcanza el 7,7%. En el modelo más ajustado, presentar normopeso (OR= 0,59; IC 95% 0,44-0,7; p=<0,001), ser mujer (OR= 0,67; IC 95% 0,49-0,89; p=<0,01), estar matriculado en carrera relacionada con la salud (OR= 0,60; IC95% 0,45-0,78; p<0,001), tener padres profesionales (OR= 0,75; IC 95% 0,60-0,95; p=<0,05) y realizar actividad física (OR= 0,34; IC 95% 0,27-0,42; p=<0,001) fueron las variables asociadas al cumplimiento del consumo de F&V. En el análisis por país, la actividad física fue la variable más asociada al consumo de F&V. Conclusión: Se observa un bajo consumo de F&V en estudiantes universitarios, y entre las variables asociadas al cumplimiento de la recomendación de F&V se encuentran estar normopeso, sexo femenino, estar cursando una carrera relacionada con la salud, tener los padres y la práctica de actividad física, siendo esta última la variable más importante.

RESUMO

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.

RESUMO

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.

RESUMO

AIM: Evaluate insulin resistance (IR) as a mediator of the effect of body fat distribution on liver fat infiltration and stiffness (LSt) in young adults using structural equation modeling (SEM). METHODS: We invited 500 first year students from two universities and evaluated their family history to determine the risk for cardiometabolic disease. Of these, 174 students (age 19 ± 1 years) were assessed for total body fat percentage (BF%), LSt, fat infiltration (Coefficient attenuated parameter CAP), and serum biochemical analysis. We performed a mediation analysis using two different structural equation models to determine the relationship between BMI, BF%, abdominal obesity (AO), IR, LSt, and fat infiltration using standardized ß coefficients. The symbol "->" means "explains/causes". RESULTS: Model#1 supported that mediation analysis and had a better fit than the direct effect. AO->IR (b = 0.62, p = 0.005), AO->CAP (b = 0.63, p <0.001), and CAP->IR (b = 0.23, p = 0.007), with negligible effect of BMI on CAP and IR. Model#2 showed direct effect of BMI on LSt was a better fit than mediation. BMI->LSt (b = 0.17, p = 0.05) but no effect AO->LSt. Interestingly, LSt->IR (b = 0.18, p = 0.001), but bi-directional IR->LSt (b = 0.23, p = 0.001). CONCLUSIONS: AO and BMI in young adults have differential phenotypic effects on liver CAP and LSt. Visceral fat had a direct effect on IR and CAP. Meanwhile, BMI was associated with LSt. Our findings shed light on the complex interplay of factors influencing liver stiffness, particularly in young individuals. Further research is needed to elucidate the precise mechanisms underlying these associations and their implications for liver health.

RESUMO

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.

RESUMO

There is evidence supporting that acute sprint interval training (SIT) might improve metabolic responses to postprandial glucose, but results are inconclusive. The aim of the present study was to explore the effects of acute SIT on metabolic response and substrate utilization in individuals with overweight/obesity after an oral 75-gram glucose challenge. Thirty-three participants with overweight/ obesity (32.7 ± 8.3 years, 24 male, 9 female) participated in the study and a crossover design was followed. After the 75-gram glucose load, participants were randomly allocated to two groups: no exercise (resting) or SIT protocol. Metabolic data including respiratory quotient (RQ) and substrate utilization rates (fats and carbohydrates) were collected using the COSMED Q-NRG + ® calorimeter. The RQ was significantly lower in the acute SIT group (0.76 [0.01]; p < 0.0001) than in the resting group (0.80 [0.01]; p = 0.036) at the 120-min postprandial time point, and the RQ area under the curve (AUC) was also lower in the SIT group (mean difference of -6.62, 95% CI -12.00 to -1.24; p = 0.0161). The contribution of fat to energy expenditure increased after SIT during the postprandial period whereas the contribution of carbohydrates decreased. The AUC for fat contribution was significantly higher (mean difference 2311.9, 95% confidence interval [CI] 578.8 to 4043.3; p = 0.0098) and the AUC for carbohydrate contribution was significantly lower (mean difference -2283.1, 95% CI -4040.2 to -527.1; p = 0.0117) in the SIT group than in the resting group. In conclusions, acute SIT might have a positive effect on metabolic responses to postprandial glucose and, accordingly, should be recommended for improving metabolism in people with overweight/obesity.

RESUMO

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.

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.

RESUMO

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.

RESUMO

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)

RESUMO

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

La creciente epidemia de obesidad ha sido uno de los retos más importantes de salud pública en México durante los últimos años. Con apoyo de la Federación Mundial de Obesidad, en 2021 formamos un grupo de profesionales para identificar y resumir las acciones prioritarias en las que puede enfocarse nuestro país para hacer frente a esta epidemia. Al proceso de desarrollo y discusión de este grupo se sumaron más de 1 000 profesionales de la salud para retomar recomendaciones de documentos y guías de alto nivel previamente publicados. En conmemoración del Día Mundial de la Obesidad, en este 2022 se presenta esta postura como insumo para el desarrollo de acciones en el ámbito profesional y de los diferentes sectores, en la que se incluyen 10 recomendaciones de acción, desde la perspectiva poblacional hasta la atención individualizada, y se enfatiza en la importancia de la participación social, de las intervenciones integrales con visión centrada en la persona y de la sostenibilidad planetaria, además de mejorar la educación y las campañas de difusión, propiciar un ambiente promotor de entornos activos y blindar de conflictos de interés los esfuerzos de prevención y control. La postura hace un llamado para abordar la obesidad de manera seria, con base en la evidencia científica, oportuna e integral, con enfoque de curso de vida, de forma ética y sensible, y sin perpetuar las barreras del estigma de peso en la sociedad.

Abstract: In recent decades, the growing obesity epidemic in Mexico has become one of the most important public health challenges faced by the country. With support from the World Obesity Federation, we formed a working group in 2021 to identify and summarize priority actions that Mexico can take to face this epidemic. More than 1 000 health professionals joined the development and discussion process. Recommendations from previously published, high-level documents and guidelines were taken into account. In commemoration of World Obesity Day 2022, this statement is presented as input for health care professionals to develop actions to address obesity. The statement includes 10 recommendations that include population-level and individual-level actions. It emphasizes the importance of social participation, comprehensive interventions with a person- centered perspective, planetary sustainability, on improving education and communication campaigns, as well as fostering a built environment that promotes active living, and shielding prevention and control efforts from conflicts of interest. The statement calls for obesity to be treated seriously, based on scientific evidence, in a timely and comprehensive manner, employing a life-course and ethical approach that does not perpetuate weight stigma in society.

RESUMO

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.

RESUMO

We previously reported preliminary characterization of adipose tissue (AT) dysfunction through the adiponectin/leptin ratio (ALR) and fasting/postprandial (F/P) gene expression in subcutaneous (SQ) adipose tissue (AT) biopsies obtained from participants in the GEMM study, a precision medicine research project. Here we present integrative data replication of previous findings from an increased number of GEMM symptom-free (SF) adults (N = 124) to improve characterization of early biomarkers for cardiovascular (CV)/immunometabolic risk in SF adults with AT dysfunction. We achieved this goal by taking advantage of the rich set of GEMM F/P 5 h time course data and three tissue samples collected at the same time and frequency on each adult participant (F/P blood, biopsies of SQAT and skeletal muscle (SKM)). We classified them with the presence/absence of AT dysfunction: low (<1) or high (>1) ALR. We also examined the presence of metabolically healthy (MH)/unhealthy (MUH) individuals through low-grade chronic subclinical inflammation (high sensitivity C-reactive protein (hsCRP)), whole body insulin sensitivity (Matsuda Index) and Metabolic Syndrome criteria in people with/without AT dysfunction. Molecular data directly measured from three tissues in a subset of participants allowed fine-scale multi-OMIC profiling of individual postprandial responses (RNA-seq in SKM and SQAT, miRNA from plasma exosomes and shotgun lipidomics in blood). Dynamic postprandial immunometabolic molecular endophenotypes were obtained to move towards a personalized, patient-defined medicine. This study offers an example of integrative translational research, which applies bench-to-bedside research to clinical medicine. Our F/P study design has the potential to characterize CV/immunometabolic early risk detection in support of precision medicine and discovery in SF individuals.
