A Landscape of Micronutrient Dietary Intake by 15- to 65-Years-Old Urban Population in 8 Latin American Countries: Results From the Latin American Study of Health and Nutrition.

BACKGROUND: Latin American countries have shifted from traditional diets rich in micronutrients to a Westernized diet rich in high energy-dense foods and low in micronutrients. OBJECTIVE: This study aimed to determine the prevalence of adequate micronutrient intakes in urban populations of 8 Latin American countries. METHOD: Micronutrient dietary intake data were collected from September 2014 to August 2015 from 9216 men and women aged 15.0 to 65.0 years living in urban populations of 8 Latin American countries. Dietary intake was collected using two 24-hour recalls on nonconsecutive days. Micronutrient adequacy of intake was calculated using the Estimated Average Requirement cut-off method. RESULTS: In general terms, the prevalence of inadequate intake of thiamine, riboflavin, niacin, folate, cobalamin, iron, phosphorus, copper, and selenium ranged from 0.4% to 9.9%. In contrast, the prevalence of inadequacy of pyridoxine, zinc, vitamin C, and vitamin A ranged from 15.7% to 51.5%. The nutrients with a critical prevalence of inadequacy were magnesium (80.5%), calcium (85.7%), and vitamin D (98.2%). The highest prevalence of inadequate intakes was observed in the low educational level, participants with overweight/obesity, in men, and varies according to socioeconomic status. CONCLUSIONS: There is an urgent need to define direct regional actions and strategies in Latin America aimed at improving micronutrient adequacy, either through staple food fortification programs, agronomic biofortification, or food policies that facilitate economic access to micronutrient-rich foods.

Plain language titleDescription of the Vitamin and Mineral Consumption Status in Urban Cities of Latin America: Results of the Latin American Health and Nutrition Study.Plain language summaryVitamins and minerals are essential for maintaining good health. However, traditional Latin American diets are changing to include foods that have a lot of sugar and fat but fewer vitamins and minerals. This study was designed to analyze the consumption of these nutrients in urban cities of 8 Latin American countries. We collected food consumption information from September 2014 to August 2015 from 9216 men and women between 15 and 65 years old using a method called 24-hour recall. To find out if participants were consuming the necessary daily amounts of vitamins and minerals, intakes were compared with the daily recommended amounts suggested by the Institutes of Medicine of the United States. We found that Latin American urban populations consume fewer vitamins and minerals than recommended. In some cases, few people do not consume the required amounts of vitamins and minerals, but in other cases, many do not. For example, few do not consume enough thiamine, riboflavin, niacin, folate, cobalamin, iron, phosphorus, copper, and selenium. However an intermediate number of people do not consume enough pyridoxine and zinc, a high number consume little vitamin C and vitamin A, and many people consume very little magnesium, calcium, and vitamin D. We found that the people who consume fewer vitamins and minerals are mostly males, overweight/obese, have lower education and varies according to their financial resources. A deficient intake of vitamins and minerals showed up in most age groups, from adolescence to adulthood. To improve vitamins and minerals intake, it is important that some foods that are frequently eaten are fortified or that the price of foods that are high in vitamins and minerals is lowered.

Energy imbalance gap was associated with body mass index and sex in Latin American adolescents-results from the ELANS study.

Introduction: Energy imbalance gap (EIG) is defined as the average daily difference between energy intake (EI) and energy expenditure (EE). This study aimed to examine the associations between EIG and sociodemographic and anthropometric variables in the adolescent population of eight Latin America countries. Methods: A total of 680 adolescents aged 15 to 18 were included in this study. The estimation of EI was based on two non-consecutive 24-h dietary recalls. EE was predicted from Schofield equations using physical activity level obtained through the long version of the International Physical Activity Questionnaire. Sociodemographic data and anthropometric measurements were also obtained. A descriptive analysis and multilevel linear regression models were used to examine associations between variables. Results: The mean EI, EE, and EIG were 2091.3 kcal, 2067.8 kcal, and 23.5 kcal, respectively. Argentina had the highest EI and EIG, whereas Chile had the lowest EI and EIG. Males had a higher EI (2262.4 kcal) and EE (2172.2 kcal) than females (1930.1 kcal and 2084.5 kcal), respectively (p < 0.05). Overweight subjects had a lower EIG than did underweight and normal-weight subjects (p < 0.05). Subjects with low socioeconomic status (SES) had a lower EE (2047.0 kcal) than those with a high SES (2164.2 kcal) (p < 0.05). Conclusion: Sex and BMI were associated with EIG in adolescents from Latin America.

Exploring the FAO Minimum Dietary Diversity Indicator as a Suitable Proxy of Micronutrient Adequacy in Men and Women Across Reproductive and Non-reproductive Ages in 8 Latin American Countries.

BACKGROUND: Women's Dietary Diversity Score (WDDS) is an indicator of dietary diversity, a key component of diet quality in women of reproductive age (WRA). Limited information is available regarding its applicability in other population groups. OBJECTIVE: To examine the ability of the Minimum Dietary Diversity for Women (MDD-W) of 5-food groups cutoff to predict micronutrient adequacy in men and women 15 to 65 years old from 8 Latin American countries. METHODS: We used a 24-hour recall from 9216 participants in the Latin American Study on Nutrition and Health (ELANS) to determine Dietary Diversity Score (DDS) based on the consumption of 10 food groups. The Mean Probability of Adequacy (MPA) was associated with DDS for the overall sample, for men, WRA, and women of nonreproductive age (WNRA). Sensitivity and specificity analyses were performed to determine if the 5-food groups cutoff point for MDD can be used to correctly identify men, WRA, and WNRA with adequate micronutrient adequacy (MPA ≥ 0.70). RESULTS: We found a mean DDS of 4.78 ± 1.33 and an MPA of 0.64 ± 0.16, with 59% of participants showing a diverse diet (DDS ≥ 5). The 5-food groups-cutoff point showed a better balance between sensitivity and specificity predicting an MPA ≥0.70 in men, WRA, and WNRA. MPA was significantly associated with DDS in WRA and for men and WNRA, as well. CONCLUSION: The 5-food group MDD, originally intended to be used in WRA, performed equally well in predicting MPA ≥0.70 in men, WRA, and WNRA, and can be used as a proxy of micronutrient adequacy in Latin American population.

Plain language titleAssessment of the FAO Minimum Dietary Diversity Index to Estimate Micronutrients Intake in Urban Cities of 8 Latin America CountriesPlain language summaryThe Women's Dietary Diversity Score (WDDS) proposed by the Food and Agriculture Organization is an indicator that measures the variety of foods consumed by women of reproductive age (WRA), and it has been reported in several studies that the more diverse the diet, the greater the probability of meeting micronutrients requirements. This indicator has not been validated in other population, but few studies have been conducted in the Latin American region. So, we aimed to investigate whether the Minimum Dietary Diversity for Women (MDD-W) established for WRA could also predict sufficient micronutrient intake in men and women aged 15 to 65 years in the Latin American population. To accomplish this objective, we used data from the Latin American Study of Nutrition and Health (Estudio Latino Americano de Nutrición y Salud­ELANS) that collected dietary data from 24-h recalls from 9216 participants and analyzed the association between DDS and the Mean Probability of Adequacy (MPA). Additionally, we determined if the MDD cutoff point could correctly identify individuals with appropriate vitamin and mineral intake. We found that the overall mean DDS was 4.78 ± 1.33, the MPA was 0.64 ± 0.16, and approximately 59% of participants had a diverse diet. The MDD of 5-food groups cutoff point was demonstrated to be useful in predicting sufficient micronutrient intake for men, WRA, and women over 50 years. Respondents with a DDS ≥5 had higher micronutrient adequacy. These findings suggest that DDS can serve as a proxy for assessing micronutrient adequacy in urban populations beyond WRA. The effect of promoting diverse diets on micronutrient adequacy as part of intervention programs can be captured by the DDS in urban Latin American populations.

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)

Developing a cooperative multicenter study in Latin America: Lessons learned from the Latin American Study of Nutrition and Health Project / Elaboração de estudo cooperativo multicêntrico na América Latina: ensinamentos do Projeto do Estudo Latino-americano de Nutrição e Saúde / Elaboración de un estudio colaborativo multicéntrico en América Latina: enseñanzas extraídas del Estudio Latinoamericano de Nutrición y Salud

ABSTRACT This report examines the challenges of conducting a multicenter, cross-sectional study of countries with diverse cultures, and shares the lessons learned. The Latin American Study of Nutrition and Health (ELANS) was used as a feasibility study involving the most populous cities of eight countries in Latin America (Argentina, Brazil, Chile, Colombia, Costa Rica, Ecuador, Peru, and Venezuela) in 2014-2015, about 40% of the population of the Americas. The target sample included 9 000 individuals, 15-65 years of age, and was stratified by geographic location (only urban areas), gender, age, and socioeconomic status. Six principal challenges were identified: team structuring and site selections; developing a single protocol; obtaining ethic approvals; completing simultaneous fieldwork; ensuring data quality; and extracting data and maintaining consistency across databases. Lessons learned show that harmonization, pilot study, uniformity of procedures, high data quality control, and communication and collaboration across sites are imperative. Barriers included organizational complexity, recruitment of collaborators and research staff, institutional cooperation, development of infrastructure, and identification of resources. Consensus on uniform measures and outcomes and data collection methodology, as well as a plan for data management and analysis, communication, publication, and dissemination of study results should be in place prior to beginning fieldwork. While challenging, such studies offer great potential for building a scientific base for studies on nutrition, physical activity, and other health topics, while facilitating comparisons among countries.

RESUMEN En este informe se examinan los retos de llevar a cabo un estudio transversal multicéntrico en países con culturas diversas y se transmiten las enseñanzas extraídas. Se usó el Estudio Latinoamericano de Nutrición y Salud (ELANS) como un estudio de factibilidad realizado en el período 2014-2015, que incluyó las ciudades más populosas de ocho países de América Latina (Argentina, Brasil, Chile, Colombia, Costa Rica, Ecuador, Perú y Venezuela) y abarcó a cerca de 40% de la población de la Región de las Américas. La muestra establecida incluyó a 9 000 personas de 15 a 65 años de edad, y fue estratificada según la ubicación geográfica (solo zonas urbanas) y por sexo, edad y situación socioeconómica. Se encontraron seis retos principales: estructurar los equipos y seleccionar los sitios; preparar un protocolo único; obtener las aprobaciones éticas; terminar simultáneamente el trabajo sobre el terreno; velar por la calidad de los datos y extraer datos y mantener la uniformidad en todas las bases de datos. Las enseñanzas extraídas muestran que la armonización, los estudios piloto, la uniformidad de los procedimientos, el riguroso control de la calidad de los datos y la comunicación y colaboración entre todos los sitios son imperativos. Los obstáculos incluyeron la complejidad de la organización, el reclutamiento de colaboradores y personal de investigación, la cooperación institucional, el desarrollo de infraestructura y la definición de los recursos. Antes de comenzar el trabajo sobre el terreno, se debe llegar a un consenso acerca de mediciones y resultados uniformes y la metodología de recopilación de datos, así como un plan para la gestión y el análisis de los datos y la comunicación, publicación y difusión de los resultados del estudio. A pesar de que estos estudios constituyen un desafío, hacen posible establecer una base científica para los estudios sobre la nutrición, la actividad física y otros temas de salud, al facilitar las comparaciones entre los países de América Latina.

RESUMO Neste relato se examinam os desafios de realizar um estudo transversal multicêntrico em países com culturas diversas e os ensinamentos tirados. O Estudo Latino-americano de Nutrição e Saúde (ELANS) serviu de estudo de viabilidade, englobando as cidades mais populosas de oito países da América Latina (Argentina, Brasil, Chile, Colômbia, Costa Rica, Equador, Peru e Venezuela) em 2014-2015, representando cerca de 40% da população das Américas. A amostra pretendida compreendeu 9.000 indivíduos com 15 a 65 anos de idade e foi estratificada por localização geográfica (exclusivamente áreas urbanas), sexo, idade e nível socioeconômico. Os seis principais desafios identificados foram: estruturar as equipes e selecionar as sedes, elaborar um único protocolo, obter as aprovações dos comitês de ética, realizar trabalho de campo simultâneo, assegurar a qualidade dos dados e extrair os dados e manter a consistência em todas as bases de dados. Os ensinamentos tirados demonstram serem imprescindíveis harmonização, estudo-piloto, uniformidade dos procedimentos, ótimo controle da qualidade dos dados e comunicação e colaboração entre as sedes. Entre as barreiras estão a complexidade organizacional, recrutamento de colaboradores e pessoal de pesquisa, cooperação institucional, desenvolvimento de infraestrutura e identificação dos recursos. Antes do início do trabalho de campo, deve-se chegar a um consenso sobre medidas e resultados uniformes e metodologia de coleta de dados assim como um plano para o gerenciamento e análise dos dados, comunicação, publicação e disseminação dos resultados dos estudos. Apesar da sua complexidade, tais estudos têm um grande potencial de fundar uma base científica para estudos de nutrição, atividade física e outros tópicos relacionados à saúde, ao mesmo tempo que facilitam comparações entre os países da América Latina.
