Perceived Urban Environment Attributes and Device-Measured Physical Activity in Latin America: An 8-Nation Study.

INTRODUCTION: Attributes of the neighborhood-built environment are associated with self-reported physical activity, but only a few studies have concentrated on device-measured physical activity in Latin America. This study examines the associations of perceived neighborhood-built environment attributes, device-measured sedentary time, and light-intensity and moderate-to-vigorous physical activity in adults from 8 Latin American countries. METHODS: Data from Estudio Latinoamericano de Nutrición y Salud adult study, an observational multicountry study (N=2,478), were analyzed in 2020. Data were collected between 2014 and 2015. Perceived neighborhood-built environment attributes were measured using the Neighbourhood Environment Walkability Survey. Sedentary time, light-intensity physical activity, and moderate-to-vigorous physical activity data were collected using accelerometers. RESULTS: No associations between perceived neighborhood-built environment attributes and sedentary time were found. Positive perceptions of walking/cycling facilities (ß=6.50, 95% CI=2.12, 10.39) were associated with more light-intensity physical activity. Perceptions of better aesthetics (Argentina) and better walking/cycling facilities (Brazil and Ecuador) were positively associated with light-intensity physical activity. Land use mix-diversity (ß=0.14, 95% CI=0.03, 0.25), walking/cycling facilities (ß=0.16, 95% CI=0.05, 0.27), aesthetics (ß=0.16, 95% CI=0.02, 0.30), and safety from traffic (ß=0.18, 95% CI=0.05, 0.24) were positively associated with moderate-to-vigorous physical activity. Land use mix-diversity, street connectivity, and safety from traffic were positively associated with moderate-to-vigorous physical activity in Venezuela. CONCLUSIONS: These findings have implications for policy recommendations, which can guide policies to promote physical activity in the region. Land use mix-diversity, walking/cycling facilities, aesthetics, and safety from traffic can maintain or increase the levels of light-intensity and moderate-to-vigorous physical activity among Latin American adults.

Association between Active Transportation and Public Transport with an Objectively Measured Meeting of Moderate-to-Vigorous Physical Activity and Daily Steps Guidelines in Adults by Sex from Eight Latin American Countries.

This study aimed to examine the associations between active transportation and public transport and the objectively measured meeting of moderate-to-vigorous physical activity (MVPA) and steps per day guidelines in adults by sex from eight Latin American countries. As part of the Latin American Study of Nutrition and Health (ELANS), data were collected from 2524 participants aged 18-65 years. MVPA and steps per day were evaluated using Actigraph GT3X accelerometers. The mode of transportation, its frequency and duration were collected using a self-reported questionnaire. The average time dedicated to active transportation was 12.8 min/day in men (IQR: 2.8-30.0) and 12.9 min/day in women (IQR: 4.3-25.7). A logistic regression analysis was conducted, showing that active transportation (≥10 min) was associated with higher odds of meeting MVPA guidelines (men: OR: 2.01; 95%CI: 1.58-2.54; women: OR: 1.57; 95%CI: 1.25-1.96). These results show a greater association when considering active transportation plus public transport (men: OR: 2.98; 95%CI: 2.31-3.91; women: OR: 1.82; 95%CI: 1.45-2.29). Active transportation plus public transport was positively associated with meeting steps per day guidelines only in men (OR: 1.55; 95%CI: 1.15-2.10). This study supports the suggestion that active transportation plus public transport is significantly associated with meeting the MVPA and daily steps recommendations.

Association between built environment and physical activity in Latin American countries: a multicentre cross-sectional study.

OBJECTIVE: To assess the association between the physical activity level and the built environment by accessibility, microinfrastructure and security in Latin America (LA). DESIGN: We conducted a multicentre cross-sectional study to collect physical activity and built environment data. The levels of physical activity were calculated through the International Physical Activity Questionnaire survey. Using the Neighbourhood Environment Walkability Scale-Abbreviated, characteristics of the built environment were measured through three domains: accessibility, microinfrastructure and security. To estimate the association of the built environment and physical activity, we used mixed effects logistic regression analysis. In addition, likelihood ratio test to account for clustered effect within countries and/or cities was used. SETTING: Eight countries in LA. PARTICIPANTS: Adults aged 15-65 years (n=9218) living in urban areas and consented to participate of the Latin American Study of Nutrition and Health. RESULTS: Most of the population in LA had access to a grocery store (97.2%), public transport stop (91.5%) and children's playground (81.6%). Metropolitan parks were more accessible in Ecuador (59.8%) and Colombia (59.2%) than in Venezuela (33.5%). Individuals located within 20 min of walking from sport facilities or children's playground areas were more likely to perform moderate-to-high physical activity OR 1.20 (95% CI 1.06 to 1.36) and OR 1.25 (95% CI 1.02 to 1.53), respectively. Only 14.5% of the population from the region considered that their neighbourhood had an adequate design for walking or cycling. Likewise, among adults living in LA, only 39.75% had the perception of living in a safe neighbourhood. CONCLUSIONS: This multicentre study shows that currently, LA built environment does not promote physical activity in the region. Our findings provide the rationale to push forward, at regional and national levels, policies and interventions that will help to achieve a safe, healthy and friendly built environment to encourage participation in active recreation and sports in leisure time.

Principales alimentos con azúcares añadidos y su variación geográfica y sociodemográfica: estudio latinoamericano de nutrición y salud (ELANS) / Main foods with added sugars and their geographic and sociodemographic variation: Latin American study of nutrition and health (ELANS)

Diversos estudios epidemiológicos y de intervención apuntan a una asociación fuerte y consistente entre la ingesta excesiva de azúcares y el riesgo de desarrollar caries dentales y enfermedades crónicas no transmisibles. El objetivo fue describir los 10 principales alimentos que contribuyen a la ingesta de azúcares añadidos en muestras representativas de poblaciones urbanas de ocho países latinoamericanos, y considerar diferencias por país, sexo, nivel socioeconómico (NSE) y grupo de edad. Se realizó una encuesta transversal multinacional en hogares de Argentina, Brasil, Chile, Colombia, Costa Rica, Ecuador, Perú y Venezuela (N=9218; 15­65 años). La contribución porcentual a la ingesta total del nutriente sirvió para identificar los alimentos aportadores. Los datos se estratificaron por país, sexo, NSE y grupo de edad y se compararon los gramos por día. Excepto en Perú y en el grupo de 50 a 65 años, los refrescos figuraron como el principal contribuyente a la ingesta de azúcares añadidos. Las bebidas caseras y las industrializadas también destacaron. Argentina fue el país con mayor ingesta de azúcares añadidos aportados por bebidas industrializadas, y Chile el país con menor frecuencia de bebidas como fuentes. Entre los 10 contribuyentes, la ingesta de azúcares añadidos fue mayor en el sexo masculino, excepto para sacarosa y pasteles dulces. Mayores ingestas de azúcares provenientes del jugo de fruta natural y sacarosa fueron observadas en el NSE más bajo. Las mayores y menores ingestas en los grupos de edad cambian de acuerdo con la fuente alimentaria. En conclusión, las bebidas azucaradas fueron los principales contribuyentes a la ingesta de azúcares añadidos, y la ingesta varió según la ubicación geográfica y los factores sociodemográficos(AU)

This study aimed to describe the top 10 foods that contribute to added sugars intake in representative samples of urban populations in eight Latin American countries, and consider differences by country, sex, socioeconomic level (SEL), and age group. A household-based, multinational, cross-sectional survey was conducted in Argentina, Brazil, Chile, Colombia, Costa Rica, Ecuador, Peru, and Venezuela (N=9218; 15­65 years). Contributors to added sugars were identified and listed based on the percentage of contribution to total intake of this nutrient. Data were stratified by country, sex, SEL, and age group, and the grams per day compared. Except in Peru and in the 50 to 65 years age group, soft drinks were the leading contributor to added sugar intake. Homemade beverages together industrialized beverages have been a prominent position on ranking. In general, the highest intake of added sugars by industrialized beverages was from Argentina, and the lowest frequency of beverages as sources of added sugars was observed in Chile. Among the top 10 contributors, male sex had highest added sugar intake, except for sucrose and sweet cakes. Higher intakes of sugars from natural fruit juice and sucrose were observed in the lower SEL. The highest and lowest intakes in the age groups change according to the food source. In conclusion, sugar-sweetened beverages were main contributors to added sugar intake, and the intake vary with geographical location and sociodemographic factors(AU)

Envejecer en el complejo entorno venezolano / Growing old in the complex Venezuelan environment

El envejecimiento transforma sustancial y progresivamente la situación de la salud individual, también influye sobre la estructura y la dinámica de la familia y la sociedad. Los niños, mujeres embarazadas y adultos mayores representan los grupos más vulnerables de la población, y ante situaciones de crisis humanitaria su rezago frente a las oportunidades ambientales se profundiza. Aun siendo el foco de atención, los abuelos siempre son los más postergados. Objetivo. Revisar el complejo entorno venezolano, las dimensiones que lo configuran, su impacto en el curso de vida y cómo afecta las condiciones de vida del adulto mayor. Materiales y métodos. Se analizaron los indicadores demográficos; socioeconómicos, como niveles de ingreso, pobreza e hiperinflación, calidad de los servicios públicos; de salud y de seguridad alimentaria y nutricional, inactividad laboral y protección social y cómo afectan las condiciones de vida del adulto mayor. Resultados. Se observaron dimensiones que muestran el impacto negativo en la calidad de vida del adulto mayor, que ahora también debe sortear a la COVID 19, además de enfrentar la orfandad de la acelerada migración de su descendencia, que ha causado la pérdida del bono demográfico y una disminución en la esperanza de vida. Conclusiones. La sistematización del conocimiento de las condiciones de vida de este importante grupo de la población es indispensable para orientar el diseño de políticas públicas dirigidas a su protección que incluya pensiones dignas, atención en salud y cuidados, para que esta población pueda contar con autonomía, independencia y participación en el desarrollo de la nación(AU)

Aging substantially and progressively transforms the individual health situation, it also influences the structure and dynamics of the family and society. Children, pregnant women and older adults represent the most vulnerable groups of the population, and in situations of humanitarian crisis their lag behind environmental opportunities deepens. Even though they are the focus of attention, grandparents are always the most neglected. Objective. Review the complex Venezuelan environment, the dimensions that make it up, its impact on the course of life and how it affects the living conditions of the elderly. Materials and methods. Demographic indicators was analyzed; socioeconomic, such as income levels, poverty and hyperinflation, quality of public services; health and food and nutritional security, labor inactivity and social protection and how they affect the living conditions of the elderly. Results. Dimensions was observed that show the negative impact on the quality of life of the elderly, who must now also overcome COVID 19, in addition to facing the orphanhood of the accelerated migration of their offspring, which has caused the loss of the demographic bonus and a decrease in life expectancy. Conclusions. The systematization of knowledge of the living conditions of this important group of the population is essential to guide the design of public policies aimed at their protection that includes decent pensions, health care and care, so that this population can count on autonomy, independence, and participation in the development of the nation(AU)

Childbearing Age Women Characteristics in Latin America. Building Evidence Bases for Early Prevention. Results from the ELANS Study.

Latin American (LA) women have been exposed to demographic and epidemiologic changes that have transformed their lifestyle, with increasing sedentary and unhealthy eating behaviors. We aimed to identify characteristics of LA women to inform public policies that would benefit these women and their future children. The Latin American Study of Nutrition and Health (ELANS) is a multicenter cross-sectional study of representative samples in eight Latin American countries (n = 9218) with a standardized protocol to investigate dietary intake, anthropometric variables, physical activity, and socioeconomic characteristics. Here we included the subsample of all 3254 women of childbearing age (15 to <45 years). The majority of ELANS women had a low socioeconomic status (53.5%), had a basic education level (56.4%), had a mostly sedentary lifestyle (61.1%), and were overweight or obese (58.7%). According to the logistic multiple regression model, living in Peru and Ecuador predicts twice the risk of being obese, and an increased neck circumference is associated with a 12-fold increased obesity risk. An increased obesity risk was also predicted by age <19 years (Relative Risk (RR) 19.8) and adequate consumption of vitamin D (RR 2.12) and iron (RR 1.3). In conclusion, the identification of these risk predictors of obesity among Latin American women may facilitate targeted prevention strategies focusing on high-risk groups to promote the long-term health of women and their children.

Is the perceived neighborhood built environment associated with domain-specific physical activity in Latin American adults? An eight-country observational study.

BACKGROUND: Characteristics of the neighborhood built environment are associated with physical activity (PA). However, few studies with representative samples have examined environmental correlates of domain-specific PA in Latin America. We examined the associations of the perceived neighborhood built environment with domain-specific PA in a large sample of adults from eight Latin American countries. METHODS: This study examined data from 8185 adults (aged 18-65 years) from eight Latin American countries. The Neighbourhood Environment Walkability Survey - Abbreviated (NEWS-A) scale was used to assess perceptions of land use mix-diversity, land use mix-access, street connectivity, walking/cycling facilities, aesthetics, safety from traffic, and safety from crime. Perceived proximity from home to public open spaces (metropolitan parks, playgrounds, public squares) and to shopping centers was also measured. Transport-related and leisure-time PA were assessed using the long form of the International Physical Activity Questionnaire. Both logistic and linear regression models were estimated on pooled data. RESULTS: Perceptions of higher land use mix-access (OR: 1.40; 95% CI: 1.22,1.61), the existence of many alternative routes in the neighbourhood (1.12; 1.04,1.20), slow speed of traffic (1.19; 1.03,1.35) and few drivers exceeding the speed limits (1.09; 1.03,1.15) were associated with greater odds of reporting at least 10 min/week of transport-related PA. Perceptions of higher levels of land use mix-diversity, better aesthetics and greater safety from crime, the presence of crosswalks and pedestrian signals, and greater proximity of shopping centers were associated with more min/week of transport-related PA. Perceptions of higher land use mix-diversity (1.12; 1.05,1.20), higher land use mix-access (1.27; 1.13,1.43), more walking/cycling facilities (1.18; 1.09,1.28), and better aesthetics (1.10; 1.02,1.18) were associated with greater odds of engaging in at least 10 min/week of leisure-time PA versus none. Perceptions of higher land use mix-diversity were associated with more min/week of leisure PA. CONCLUSIONS: Different perceived neighborhood built environment characteristics were associated with domain-specific PA among adults from Latin America countries. Interventions designed to modify perceptions of the neighbourhood built environment might influence initiation or maintenance of domain-specific PA. TRIAL REGISTRATION: ClinicalTrials.

Bases para el desarrollo de políticas y programas para garantizar el bienestar en los primeros mil días de vida / Bases for the development of Policies and Programs to guarantee well-being in the first thousand days of life

Los primeros mil días de vida, desde la concepción hasta el final de los primeros dos años de vida, constituye un período crucial para establecer el desarrollo de la enfermedad o de la salud en la vida futura de los individuos. La exposición a ambientes adversos determinará las alteraciones temporales en el ADN que perduran en el tiempo que dicha exposición exista. Las políticas y programas destinados a garantizar el bienestar durante esta ventana crítica del crecimiento son cruciales para que la población goce de las mejores condiciones posibles que permitan la expresión de su máximo potencial, al cual están programados para desarrollar. Palabras clave: condiciones ambientales, programas y políticas(AU)

The first thousand days of life, from the conception until the end of the first two years of life, constitutes a key period in which the development of disease or health establishes in the future lives of individuals. Exposure to adverse environments will determine the temporary impairments in DNA that last as long as the exposure exists. Policies and programs aimed at guaranteeing well-being during this critical window of growth are crucial for the population to enjoy the best possible conditions that allow the expression of their maximum potential, to which they are programmed to develop(AU)

Comparison of self-report versus accelerometer - measured physical activity and sedentary behaviors and their association with body composition in Latin American countries.

BACKGROUND: Most population-based studies from Latin America have used questionnaires to measure physical activity (PA) and sedentary behaviors (SB). Low reliability and validity of the questionnaires has limited the capacity to examine associations between PA and health. The purpose of this study was to compare self-reported and accelerometer-measured PA and SB and their associations with body composition in Latin American countries. METHODS: Data were obtained from the Latin American Study of Nutrition and Health (aged 15-65 years), collected from September 2014 to February 2015. PA and SB were assessed using the International Physical Activity Questionnaire (long version) and the Actigraph GT3X+ accelerometer. Outcomes of interest included: body mass index (BMI), waist (WC) and neck circumference (NC). We used the Pearson and intraclass correlation coefficient, Bland-Altman plots, and multilevel linear regression models. RESULTS: Mean moderate-to-vigorous physical activity (MVPA) by accelerometer and IPAQ were 34.4 min/day (95% CI: 33.4 to 35.4) and 45.6 min/day (95% CI: 43.2 to 48.1), respectively. For SB (accelerometer and IPAQ) the means were 573.1 (95% CI: 568.2 to 577.9) and 231.9 min/day (95% CI: 225.5 to 238.3). MVPA, measured by the accelerometer was negatively associated with BMI (ß = -1.95; 95% CI: -2.83 to -1.08), WC (ß = -5.04; 95% CI: -7.18 to -2.89) and NC (ß = -1.21; 95% CI: -1.79 to -0.63). The MVPA estimated through IPAQ was not significantly associated with any of the three outcome variables. SB, measured by the accelerometer, was positively associated with BMI (ß = 0.26; 95% CI: 0.08 to 0.44) and WC (ß = 0.48; 95% CI: 0.13 to 0.91). SB estimated through IPAQ was positively associated with NC only. CONCLUSIONS: Low correlation coefficients were observed for accelerometer-derived and IPAQ-reported estimates of PA and SB. Caution is advised when making comparisons between accelerometer-measured and self-reported PA and SB. Further, studies examining associations between movement and health should discuss the impact of PA and SB measurement methodology on the results obtained.

Methodological design for the assessment of physical activity and sedentary time in eight Latin American countries - The ELANS study.

Worldwide studies of physical activity and sedentary time have historically under-represented low- and middle-income countries due to the lack of surveillance data. The purpose of this paper is to describe the methods and procedures used for the assessment of physical activity and sedentary time in the Latin American Study of Nutrition and Health (Estudio Latinoamericano de Nutrición y Salud; ELANS). ELANS is a multicentre, cross-sectional and surveillance study of a nationally representative sample from eight Latin American countries: Argentina, Brazil, Chile, Colombia, Costa Rica, Ecuador, Peru, and Venezuela. Two instruments were used to evaluate different domains and intensities of physical activity and sedentary time: self-reported data and a triaxial accelerometer (model GT3X+). ELANS will generate important self-reported and objective information for the Latin American populations, namely:•evidence on the distribution of physical activity and sedentary time across population subgroups (e.g. sex, age, socioeconomic- and educational level). These sets of information will increase the evidence base and can help to inform future intervention strategies in Latin America;•self-reported and objective information on physical activity and sedentary time.

Anthropometry, dietary intake, physical activity and sitting time patterns in adolescents aged 15-17 years: an international comparison in eight Latin American countries.

BACKGROUND: Although there is high prevalence of obesity and other cardiovascular risk factors among Latin American adolescents, there is limited evidence on dietary intake and physical activity (PA) patterns in this population. Therefore, we characterized anthropometry, dietary intake, PA and sitting time (ST) in adolescents aged 15-17 years from eight Latin American countries. METHODS: Six hundred seventy-one adolescents (41.4% girls) from the Latin American Study of Nutrition and Health (ELANS) were included. Nutritional status was classified by four BMI (kg/m2) categories. Waist circumference (WC) was categorized as above or below thresholds. Dietary intake was assessed through two non-consecutive 24-h dietary recalls. PA and ST were measured using the International Physical Activity Questionnaire (IPAQ). We calculated overall and country-specific estimates by sex and tested for differences between boys and girls. RESULTS: Differences in the prevalence of overweightness (15.1 and 21.6%) and obesity (8.5 and 6.5%) between boys and girls, respectively, were statistically insignificant (p = 0.059). Average energy intake was 2289.7 kcal/day (95% CI: 2231-2350) for boys and 1904.2 kcal/day (95% CI: 1840-1963) for girls (p < 0.001). In relation to macronutrient intake for boys and girls, respectively, the average intake (expressed as percentage of total energy) was 15.0 and 14.9% for protein; 55.4 and 54.9% for carbohydrates; 14.1 and 14.5% for added sugar; 29.5 and 30.1% for total fat; and 9.6 and 9.9% for saturated fat (p > 0.05 for all outcomes). There was no statistically significant difference in the prevalence of total energy (TE) saturated fat and added sugar (>10% of TE) between girls and boys (49.6% versus 44.8 and 81.7% versus 76.1%, respectively). Prevalence of physical inactivity was 19% in boys and 43.7% in girls (p < 0.001). Median levels of vigorous-intensity PA and total PA were significantly higher for boys than for girls (p < 0.05 for both outcomes); whereas levels of ST were similar (273.7 versus 220.0 min/day for boys and girls, respectively; p > 0.05). CONCLUSIONS: These findings highlight the high prevalence of poor dietary intake and physical inactivity in adolescents from Latin American countries. Therefore, effective and sustainable strategies and programmes are needed that promote healthier diets, regular PA and reduce ST among Latin American adolescents.

Socio-demographic patterning of objectively measured physical activity and sedentary behaviours in eight Latin American countries: Findings from the ELANS study.

Physical activity (PA) and sedentary behaviours (SB) are two independent risk factors for non-communicable diseases. However, there is a lack of objectively measured information on PA and SB in low- and middle-income countries. The aim of this study was to use objective data to characterise socio-demographic patterns of PA and SB in eight Latin American countries. 2732 participants (aged 15-65 years) from the Latin American Study of Nutrition and Health (ELANS) were included. PA and SB data were collected using accelerometers. Overall and country-specific average levels of time spent in PA and SB were compared by sex, age, socioeconomic and education level. Overall, the mean time spent in SB was 571.6 min/day, ranging from 553.8 min/day in Chile to 596.7 min/day in Peru. Average levels of light, moderate-to-vigorous physical activity (MVPA) and total PA were 311.1 min/day (95% CI: 307.7; 314.5), 34.9 min/day (95% CI: 34.0; 35.9) and 7531.2 MET-min/week (95% CI: 7450.4; 7611.9), respectively. MVPA and total PA were higher in men than women. The prevalence of physical inactivity was 40.6%, ranging from 26.9% (Chile) to 47% (Costa Rica and Venezuela). Women were more physically inactive than men (47.7% versus 33.0%). SB levels were highest among those with higher education; PA graded positively with socioeconomic level. Our findings can inform the planning of health policies and programmes designed to reduce levels of physical inactivity, as well as inform the local and cultural adaptation of these policies and programmes for implementation in Latin America. Highlights Worldwide studies of physical activity (PA) and sedentary behaviours (SB) have historically under-represented Latin American countries due to the lack of surveillance data. Across eight Latin American countries, the ELANS study collected data on PA and SB using an objective method (accelerometers) which we have analysed to quantify and characterise socio-demographic patterns. Over four-in-ten participants were physically inactive (40.6%); with a gender gap (47.7% women; 33.0% men); and striking differences between countries (47% Costa Rica and Venezuela; 26.9% Chile). In all countries, levels of moderate-to-vigorous physical activity (MVPA) were lowest, and levels of SB were highest, among participants in the higher education groups. Our findings on the unequal distribution of PA and SB increases the evidence base and can help to inform future intervention strategies in Latin America.

Los dilemas entre el cambio climático, la dieta saludable/sostenible y la sindemia de las sociedades post-modernas / Dilemmas between climate change, sustainable/healthy diets and the syndemics of post-modern societies

El mundo moderno presenta grandes brechas en la superación de las desigualdades que agobian a millones de personas y que tiene un impacto en la calidad de vida de las personas. La coexistencia de tres epidemias: desnutrición, obesidad y cambio climático, representan los desafíos que para alimentar adecuadamente al planeta deben abordarse, desde una perspectiva critica a la ciencia tradicional. Tanto la obesidad como la desnutrición, son enfermedades reconocidas que alteran la salud de las personas y representan un incremento de los riesgos para el desarrollo de enfermedades a futuro, por lo que la alimentación adecuada, equilibrada y suficiente es una necesidad real. Como lograr una dieta que pueda sostenerse en el tiempo y que apunte al mejoramiento de las condiciones climáticas del planeta a la vez que logra cubrir los requerimientos nutricionales constituye una intensa controversia científica, política y social. La narrativa escondida detrás de la estadística que describe los fenómenos de obesidad, desnutrición y cambios climáticos, debe ser colocada al frente de los debates, y para esto se necesita ampliar la visión de los problemas básicos que enfrenta la humanidad para comer. Para explicar este fenómeno se necesita con urgencia una visión holística que incluya la estructura metodológica científica, el enfoque transectorial y el relato social cualitativo. En este trabajo se revisa el dilema moderno y se intenta ampliar el horizonte del entendimiento a través de preguntas provocadoras que puedan contribuir al avance en el entendimiento de controversias tradicionales como hambre y política(AU)

The modern world is showing huge gaps for overcoming the inequalities that overwhelm millions of people, which have an impact on population 's quality of life. The coexistence of three epidemics: undernutrition, obesity and climate change represent the challenges that should be faced from a critical perspective of the traditional science in order to adequately feed the planet. Obesity as well as undernutrition are recognized diseases that impair the people's health and represent an increased risk for the development of future diseases. Because of this, a real necessity is the achievement of a balanced, adequate and sufficient diet for all. How to achieve a sustainable diet over time and also to cooperate in the amelioration of the planet's climate changes has become an intense scientific, political and social controversy. The hidden narrative behind the statistics must be brought to the forefront of the debates and for this, it is necessary to broaden the vision of the basic problems faced by the humanity for eating. To explain this phenomenon, a holistic perspective is urgently needed that includes the methodological scientific structure, a trans-sectorial approach and a social qualitative description. In this paper, the modern dilemma is reviewed and an attempt is made to broaden the horizon of understanding through provocative questions that may contribute to advancing the comprehensive approach of the traditional controversies such as hunger and politics(AU)

Acerca del placer de comer en los estratos socioeconómicos bajos venezolanos / On eating's pleasure of the Venezuelan low income socioeconomic status

La alimentación desde una perspectiva integral, es un proceso interdisciplinario que no se limita a la satisfacción de los requerimientos alimentarios y nutricionales para reparar tejidos y coadyuvar en funciones vitales para el organismo. Es un proceso multidimensional en el cual se articulan lo biológico, lo ecológico, lo social y lo cultural, que ocupa un lugar importante en la vida de los humanos al evocar recuerdos y memorias afectivas, dando lugar a procesos de identificación individual, familiar, sociales y culturales. Este estudio intenta explorar las preferencias y aspiraciones que despiertan los deseos de consumir alimentos en los estratos socioeconómicos bajos y estudiar algunos elementos del entorno asociados a los mismos. Se trata de una investigación cualitativa realizada mediante entrevistas a cocineras y madres que acuden a comedores de asistencia nutricional en la presente crisis que experimenta Venezuela. Los resultados conllevan un escenario desalentador para la preservación de las tradiciones culinarias Venezolanas, debido a que tanto las cocineras como las madres que asisten a los comedores refieren que sus preparaciones elegidas como el "sueño" si el dinero no fuera un problema, son las pastas o el arroz con pollo o carne, mostrando una ausencia en las preferencias de platos tradicionales venezolanos incluyendo los postres. Se concluye que existe las preferencias de este grupo de mujeres no incluyen platos venezolanos tradicionales y se sugiere que dentro de la educación nutricional para mejorar la variedad y calidad de la dieta de las comunidades, deben incluirse módulos de gastronomía y preparación de recetas que puedan orientar y rescatar el gusto por las tradiciones culinarias venezolanas(AU)

Feeding people from a comprehensive perspective is an interdisciplinary process that is not limited to meeting food and nutritional requirements to repair tissues and assist in vital functions for the body. It is a multidimensional process in which the biological, the ecological, the social and the cultural dimensions are intertwined, and has an important place in the lives of humans by evoking affective memories, giving as a result identification processes at individual, family, social and cultural levels. This study intents to explore the preferences and aspirations that arouse the desire to consume certain foods in the Venezuelan lower socioeconomic strata and to study some elements of the environment associated with them. This is a qualitative research conducted through interviews with cooks and mothers who go to assistance soup-kitchens in the current crisis that Venezuela is experiencing. The results lead to a discouraging scenario for the preservation of Venezuelan culinary traditions, because both the cooks and the mothers who attend the referred centers reported that their "dream" chosen preparations if money were not a problem, are pasta or rice with chicken or meat, showing an absence in the preferences of traditional Venezuelan dishes including desserts. It is concluded that the preferences of this group of women do not include traditional Venezuelan dishes and it is suggested that within the nutritional education to improve the variety and quality of the communities' diet, modules of gastronomy and preparation of recipes that can guide and rescue the taste for Venezuelan culinary traditions should be included(AU)

Original research Socio-demographic patterning of self-reported physical activity and sitting time in Latin American countries: findings from ELANS.

BACKGROUND: Low levels of physical activity (PA) and prolonged sitting time (ST) increase the risk of non-communicable diseases and mortality, and can be influenced by socio-demographic characteristics. The aim of this study was to use self-report data to characterise socio-demographic patterns of PA and ST in eight Latin American countries. METHODS: Data were obtained from the Latin American Study of Nutrition and Health (ELANS), a household population-based, multi-national, cross-sectional survey (n = 9218, aged 15-65 years), collected from September 2014 to February 2015. Transport and leisure PA and ST were assessed using the International Physical Activity Questionnaire-long version. Overall and country-specific mean and median levels of time spent in transport and leisure PA and ST were compared by sex, age, socioeconomic and education level. RESULTS: Mean levels of transport and leisure PA were 220.3 min/week (ranging from 177.6 min/week in Venezuela to 275.3 min/week in Costa Rica) and 316.4 min/week (ranging from 272.1 min/week in Peru to 401.4 min/week in Ecuador). Transport and leisure PA were higher (p < 0.005) in men than women with mean differences of 58.0 and 34.0 min/week. The mean and median for transport PA were similar across age groups (15-29 years: mean 215.5 and median 120 min/week; 30-59 years: mean 225.0 and median 120 min/week; ≥60 years: mean 212.0 and median 120 min/week). The median time spent in transport and leisure PA between three strata of socioeconomic and education levels were similar. The prevalence of not meeting PA recommendations were 69.9% (95% CI: 68.9-70.8) for transport and 72.8% (95% CI: 72.0-73.7) for leisure. Men, younger people (15-29 years), individuals with higher socioeconomic and education levels spent significantly (p < 0.001) more time sitting than women, older people (30-59 years and ≥ 60 years) and those in the middle and low socioeconomic and education groups, respectively. CONCLUSIONS: Transport and leisure PA and ST range widely by country, sex, and age group in Latin America. Programs for promoting leisure and transport PA and reducing ST in Latin America should consider these differences by age and gender and between countries.

Recomendaciones nutricionales para el personal de salud y el personal esencial expuesto a la COVID-19 en Latinoamérica / Nutritional Recommendations for Healthcare and Essential Personnel Exposed to COVID-19 in Latin America

Estas recomendaciones se basan en la evidencia científica actual derivada de meta-análisis y revisiones sistemáticas sobre nutrición y prevención de infecciones respiratorias causadas por los virus SARS-CoV, MERS-CoV o influenza, similares en su estructura al SARS-CoV-2. Están dirigidas al personal en la primera línea de atención de salud y al personal que presta servicios esenciales a la comunidad, con alto riesgo de infección por la COVID-19. Estas personas usan equipo de protección personal, cumplen largos turnos laborales, en ocasiones bajo condiciones extremas, lo que puede llevar a descanso insuficiente, alto nivel de estrés, depresión, pobre calidad en la alimentación y deshidratación. Todos estos factores influyen negativamente en el sistema inmune y podrían conllevar un mayor riesgo de infección. Una ingesta adecuada de micronutrientes y otros compuestos bioactivos es esencial para el desempeño óptimo del sistema inmune. Existe evidencia moderada que avala la suplementación, en forma individual, con vitamina C (2 000 mg), vitamina D (1 000-2 000 UI) y zinc (≤ 40 mg) en la prevención de infecciones respiratorias en adultos. No se encontró evidencia suficiente para avalar la suplementación con vitamina A, niacina, ácido fólico, B12, omega 3, probióticos y polifenoles, aunque si se recomienda el consumo de alimentos ricos en estos nutrientes para apoyar al sistema inmune. Se recomienda al personal seguir la recomendación de consumir 5 porciones/día (400 g) de frutas y vegetales/hortalizas, mantenerse hidratado y limitar la cafeína. No hay evidencia del consumo de alimentos alcalinos para prevenir infecciones. Estas recomendaciones son particularmente importantes durante la pandemia(AU)

These recommendations are based on current scientific evidence obtained through meta-analysis and systematic reviews on nutrition and the prevention of respiratory infections related to SARS-CoV, MERS-CoV or influenza, similar in structure to SARS-CoV-2. They are aimed at primary health care personnel and to those who provide essential services to the community and are, consequently, at high risk of COVID-19 infection. These individuals wear personal protective equipment, work long shifts, sometimes under extreme conditions, which can lead to insufficient rest, high stress levels, depression, poor nutrition and dehydration. Together, these factors have a negative impact on the immune system and could result in an increased risk of infection. An adequate intake of micronutrients and other bioactive compounds is essential for optimal immune performance. There is moderate evidence supporting supplementation, individually, with vitamin C (2 000 mg), vitamin D (1 000-2 000 IU) and zinc (≤40 mg) for the prevention of respiratory infections in adults. Insufficient evidence was found to support supplementation with vitamin A, niacin, folic acid, B12, omega 3, probiotics and polyphenols; however, the consumption of foods rich in these nutrients is recommended to support immune function. It is recommended that workers follow the recommendation of consuming 400 g/day of fruits and vegetables, remain hydrated and limit caffeine. There is no scientific evidence supporting the consumption of alkaline foods to prevent infections. The aforementioned recommendations are particularly relevant during the pandemic(AU)

Recomendaciones de micronutrientes para grupos vulnerables en contexto de desnutrición, durante la pandemia de COVID-19 en Latinoamérica / Micronutrient recommendations for vulnerable groups in context of undernutrition, during the COVID-19 pandemic in Latin America

La crisis por COVID-19 (SARS-CoV-2) puede convertirse en una catástrofe alimentaria para Latinoamérica, aumentando las personas que padecen hambre de 135 a 265 millones, especialmente en Venezuela, Guatemala, Honduras, Haití y El Salvador, que ya enfrentaban crisis económicas y sanitarias. Este manuscrito presenta la posición de un grupo de expertos latinoamericanos sobre las recomendaciones de consumo y/o suplementación con vitamina A, C, D, zinc, hierro, folatos y micronutrientes múltiples, en contextos de desnutrición, para grupos vulnerables: mujeres embarazadas y lactantes, niñas y niños menores de 5 años y adultos mayores. Las recomendaciones buscan disminuir el impacto potencial que tendrá COVID-19 en el estado nutricional, durante la pandemia. La posición surge de la discusión de dichos expertos con base a la revisión de evidencia científica actual para estos grupos vulnerables. Está dirigida a tomadores de decisiones, encargados de políticas públicas, personal de salud y organismos de la sociedad civil. Después de la lactancia materna y una dieta suficiente en cantidad y calidad, la suplementación con los micronutrientes presentados, puede contribuir a prevenir y tratar enfermedades virales, reforzar el sistema inmune y reducir complicaciones. La lactancia materna con medidas de higiene respiratoria, el suministro de múltiples micronutrientes en polvo para niños desde los 6 meses hasta los 5 años y el aporte de hierro y folatos o micronutrientes múltiples para la embarazada, son estrategias comprobadas y eficaces que deben seguirse implementando en tiempos de COVID-19. Para los adultos mayores la suplementación con vitamina C, D y zinc puede estar indicada(AU)

The COVID-19 crisis (SARS-CoV-2) might transform into a food catastrophe in Latin America and would increase the number of people suffering from hunger from 135 to 265 million, particularly in Venezuela, Guatemala, Honduras, Haiti and El Salvador, already facing economic and health crises. This manuscript presents the position of a group of Latin American experts in nutrition for establishing the recommendations for consumption and / or supplementation with vitamin A, C, D, zinc, iron, folates and multiple micronutrients, in undernutrition contexts, for vulnerable population of pregnant and lactating women, children under 5 years and the elderly. The recommendations seek to decrease the potential impact that COVID-19 will have on nutritional status during the pandemic. The position arises from the discussion of the experts based on the review of current scientific evidence for these vulnerable groups. It aims to reach stakeholders, public policy makers, health personnel and civil society organizations. Only after breastfeeding and a sufficient diet in terms of quantity and quality, a supplementation with the micronutrients mentioned above can help prevent and treat viral diseases, strengthen the immune system and even reduce complications. Breastfeeding with respiratory hygiene measures, the provision of multiple micronutrients powders for children from 6 moths to 5 years of age and the supply of iron and folates or multiple micronutrients tablets for pregnant women are proven and effective strategies that must continue to be implemented during COVID-19 pandemic. For older adults, supplementation with vitamin C, D and zinc might be indicated(AU)

Association of moderate-to-vigorous physical activity with neck circumference in eight Latin American countries.

BACKGROUND: Physical activity is a cornerstone in the prevention and treatment of obesity. There are relatively few studies that explore the effect of accelerometer-determined moderate-to-vigorous physical activity (MVPA) on neck circumference (NC), most of them confined to single high-income countries. The present study investigated the association of accelerometer-determined MVPA with NC in adolescents and adults from eight Latin American countries, which are mostly upper-middle income countries. METHODS: The sample consisted of 2370 participants (47.8% male) from the Latin American Study of Nutrition and Health, a multicenter cross-sectional nutrition and health surveillance study of a nationally representative sample from eight Latin American countries (Argentina, Brazil, Chile, Colombia, Costa Rica, Ecuador, Peru, and Venezuela). Times (min/day) in MVPA (defined as time accumulated at ≥1952 activity counts/min) was assessed by ActiGraph GT3X+ accelerometer over 7 days. NC for adolescent was categorized as abnormal if circumference was > 34.5 cm for boys and > 31.25 for girls, whereas for adults the cut-off points for abnormal were > 39 cm for men and > 35 cm women. Multilevel logistic models, including country and region as random effects and adjusted for sex, age, socioeconomic level, and educational level, were used to study the association between MVPA and NC. RESULTS: The average time of MVPA was 34.88 min/day, ranging from 31.16 in Venezuela to 40.27 in Chile. Concerning NC, 37.0% of the sample was classified as having elevated NC. Chile was the country with the highest percentage of people with elevated NC (56.9%), and Colombia had the lowest percentage (24.8%). Overall, the MVPA (min/day) was associated with elevated NC (OR = 0.994, CI95% = 0.990-0.998). In Costa Rica and Peru, there were significant associations between MVPA and NC when analyzed by country. CONCLUSIONS: The present study provided evidence of significant associations between MVPA and NC in adolescents and adults from Latin America, independent of sex, age, socioeconomic level, and educational level. This analysis of accelerometry data and NC represents the first examination of these associations in eight Latin America countries. Further research is required to understand the differences between countries in the observed associations. TRIAL REGISTRATION: ClinicalTrials.Gov NCT02226627 .

Alcohol drinking, smoking and food insecurity in Venezuelan parents as potential determinants of their children's growth

Life conditions are key factors for defining growth and development of future generations. Exposure of parents to alcohol, tobacco, food insecurity conditions and adverse socioeconomic environment as part of their lifestyle and quality of life, have been reported to affect their children's health and wellbeing. Prenatal exposures have been extensively documented, but less is known about influences from parental harmful habits and disadvantaged environment during children's school years. The aim of this study is to examine potential associations between parental habits and environmental socioeconomic conditions, including food security status, and anthropometric characteristics of their children. Parental smoking, alcohol intake, food security, and socioeconomic status (SES) were explored in parents of 1730 children recruited at private and public schools in eight Venezuelan cities. These qualitative variables were collected through a semi-structured questionnaire. Weight, height and body mass index were measured using standardized methods in children. Height and BMI were converted to z-scores according to WHO international growth reference. Low BMI z-scores in children were significantly associated with mothers consuming alcohol. The frequency of children with short stature was higher in households with impaired access to quality foods and where mothers reported low and very low food security status. In brief, our study indicates that social environment could have detrimental effects on child anthropometry thus, affecting their wellbeing(AU)

Las condiciones de vida son factores clave para definir el crecimiento y el desarrollo de las generaciones futuras. La exposición de los padres al alcohol, el tabaco, las condiciones de inseguridad alimentaria y el entorno socioeconómico adverso afectan la salud y el bienestar de sus hijos. Los efectos prenatales se han documentado ampliamente, pero se conoce menos sobre las influencias de los hábitos nocivos de los padres y el entorno desfavorable en los niños durante la edad escolar. Se examinan las posibles asociaciones entre los hábitos alcohólicos, tabaquismo, nivel socioeconómico y seguridad alimentaria de los padres y el estado de crecimiento físico de los hijos. La muestra fue de 1730 niños y sus padres, de escuelas privadas y públicas en ocho ciudades venezolana, 2011. Se aplicó un cuestionario semiestructurado para las variables cualitativas y se midió peso, talla, IMC, ambos se analizaron con la referencia de la OMS. El IMC bajo en los niños se asoció significativamente con las madres que consumían alcohol. La frecuencia de los niños con estatura baja fue mayor en los hogares con acceso limitado a alimentos de calidad y estado de seguridad alimentaria bajo y muy bajo. IMC alto 15,7%. Los padres con hábitos de estilo de vida, que incluye consumo regular de alcohol y estar en un hogar con inseguridad alimentaria, pueden descuidar el cuidado de sus hijos y de una nutrición adecuada, que pueden influir en alteraciones en el crecimiento, así como también, en la aparición de enfermedades crónicas en los adultos(AU)

Estudio piloto del programa internacional de balance energético para niños en una escuela de caracas / Pilot study of the international program of energy balance for children in a school in caracas

El Programa Balance Energético para Niños (EB4K, en inglés), incluye una metodología que integra múltiples componentes utilizado inicialmente para prevenir la obesidad desde la escuela, en los Estados Unidos, basado en evidencia científica. Este modelo se adaptó para un estudio piloto en una escuela de bajos recursos del Municipio Sucre del Estado Miranda de Venezuela, cuyo objetivo fue evaluar la efectividad del programa EB4K. Se planteó un estudio longitudinal, cuasi-experimental con diseño pre y post intervención, de 12 semanas de duración en el cual se aplicó el programa educativo EB4K a 133 estudiantes de 3ro a 5to grado de educación básica. Se evaluaron datos demográficos, estado nutricional antropométrico, conocimiento nutricional, frecuencia de desayuno semanal y conocimiento sobre actividad física mediante un cuestionario desarrollado con base en el original de EB4K y adaptado para tal fin. Posterior a la intervención, el estado nutricional antropométrico clasificado por Índice de Masa Corporal para la edad, presentó una tendencia a disminuir en 11,3% de los sujetos; se registró un aumento de 8,2% en el conocimiento nutricional y de 4,5% para la ingesta diaria de desayuno. No se observaron cambios en relación al conocimiento sobre actividad física. Se concluye que el programa EB4K, pudiera generar cambios positivos en los escolares, especialmente en el manejo de los conocimientos nutricionales, siendo la práctica de actividad física una de las variables cuyo tratamiento debe ser reforzado en el programa(AU)

The Energy Balance for Kids (EB4K) Program is founded on an evidence based multicomponent methodology initially implemented to prevent obesity in school environments in the USA. This model was adapted for a pilot study with the aim to evaluate the effectiveness of the EB4K revised program for Venezuela, in a low-income school at Sucre Municipality of Miranda State. This is a longitudinal, quasi-experimental study with a design before and after the lasting 12 weeks in which the EB4K educational program was applied to 133 students from 3rd to 5th grade of basic elementary school. Demographic data, anthropometric nutritional status, nutritional information, frequency of weekly breakfast and knowledge of physical activity were evaluated through a questionnaire developed based on the original EB4K and adapted for that purpose. After the 12 weeks, there was an increase of 8.2% in the nutritional knowledge and 4.5% for the daily breakfast intake, after the intervention. Regarding the knowledge about physical activity, no changes were observed, while the anthropometric nutritional status classified by Body Mass Index for age showed a tendency to decrease in 11.3% of the subjects, after 12 weeks. In conclusion, the EB4K program could generate positive changes in schoolchildren, especially in nutritional knowledge, being the practice of physical activity a message that should be reinforced in this program(AU)
