Latin America and the Caribbean Code Against Cancer 1st edition: Building capacity on cancer prevention to primary healthcare professionals.

INTRODUCTION: Every year 1.5 million new cancer cases are diagnosed in Latin America and the Caribbean (LAC). Of these, about 40 % could be prevented. Health illiteracy has been identified as a main barrier for cancer prevention. Primary healthcare professionals (HCP) are key in cancer prevention as they are the first entry point of the population into the healthcare system. The LAC Code Against Cancer 1st edition aims to improve health literacy and awareness of cancer prevention in the LAC population, through building capacity of primary HCP. METHODS: The definition and development of the learning objectives, curriculum, structure, and evaluation of an online learning program for primary HCP was led by a dedicated group of experts from the LAC Code Against Cancer project. A pedagogical guideline and a template to ensure harmonization across topics were produced to guide the program development. Two rounds of internal revisions and an editorial process were performed. RESULTS: An online competency-based microlearning program for primary HCP was produced, taking the LAC Code Against Cancer as a basis. The competences addressed in the curriculum are core knowledge, communication skills, decision-making and applying knowledge to real-world situations. A comprehensive evaluation to assess acquisition of these competences, based on the Miller's Pyramid, was designed with three data collection points: a) immediately before, to assess baseline knowledge and skills; b) immediately after, to determine acquired competences; and c) at 3-6 months follow-up, to assess performance in daily practice. The e-learning will be freely available in the Virtual Campus for Public Health of the Pan American Health Organization in Spanish, English, and Portuguese. CONCLUSION: Primary HCP, perceived as trustworthy sources of information, are key actors to increase the population's awareness and literacy on cancer prevention. Building capacity of these professionals has the potential to increase dissemination and impact of the LAC Code Against Cancer by prompting communication with the public and offering personalized actionable preventive messages through counselling.

Consumption of Micronutrient Powder, Syrup or Fortified Food Significantly Improves Zinc and Iron Status in Young Mexican Children: A Cluster Randomized Trial.

The objective of this study was to compare the effect of three micronutrient products on biomarkers of iron and zinc status of Mexican children 6−12 months of age. As part of research to improve the impact of a national program, 54 communities were randomly assigned to receive: (1) fortified food (FF), provided by the program at the time, or (2) micronutrient powders (MNP) or (3) syrup. Each product contained 10 mg each of zinc and iron, plus other micronutrients. Children consumed the product 6 days/week for four months. Primary outcomes were changes in serum zinc, ferritin, soluble transferrin receptor, hemoglobin concentrations, and their deficiencies. Zinc concentration increased significantly from baseline to follow-up in all groups, with the largest change in the syrup group (geometric mean difference: +4.4 µmol/L; 95%CI: 3.2, 5.5), followed by MNP (+2.9 µmol/L; 95%CI: 2.1, 3.6) and FF (+0.9 µmol/L; 95%CI: 0.3, 1.6). There was a significant increase in hemoglobin concentration (+5.5 g/L; 2.5, 8.4) and a significant reduction in anemia prevalence (44.2% to 26.8%, p < 0.01) only in the MNP group. Compliance differed significantly among groups (MNP vs. FF, p = 0.04; MNP vs. syrup, p = 0.04), but may not fully explain the greater improvement in zinc and iron status in the syrup and MNP groups. The food matrix may influence nutrient utilization from supplements.

Talla baja y sobrepeso en menores de 5 años que habitan la Sierra Tarahumara, México / Stunting and overweight in children under 5y who inhabit the Sierra Tarahumara in northern Mexico

La doble carga de la desnutrición y el exceso de peso (o mala nutrición) es uno de los indicadores que mejor ilustra las inequidades en salud que existen en zonas indígenas de México. Por otro lado, existe escasa evidencia del estado de nutrición en población Tarahumara. Objetivo: Estimar indicadores del estado de nutrición y su asociación con factores sociodemográficos en población indígena Tarahumara menor de 5 años. Métodos: Estudio transversal en 21 localidades indígenas de la Sierra Tarahumara en Chihuahua, México, que analizó información sociodemográfica, de salud y antropométrica en población infantil de 6 a 59 meses de edad (n=323). Se estimaron índices antropométricos y su asociación con variables de interés mediante regresión logística múltiple. Un valor de p ≤0,05 fue considerado como estadísticamente significativo. Todos los análisis se realizaron en el paquete estadístico Stata v14.2. Resultados: Se encontraron altas prevalencias de talla baja (44,4%), emaciación (5,3%), bajo peso (11,9%) y sobrepeso (15,2%). El sexo masculino se asoció significativamente con talla baja (Razón de Momios (RM)=2,5; 1,45-4,34), mientras que, ninguna escolaridad de la madre (RM=0,39; 0,15-0,99) y ser beneficiario de un programa local de nutrición por más de 2 años se asoció con sobrepeso (RM=2,97; 1,26 -6,97). Conclusión: Se encontraron indicadores de mala nutrición en la muestra estudiada; éstos hallazgos podrían sugerir la existencia de inequidad y rezago en salud y nutrición de población infantil indígena Tarahumara. Se requieren más estudios que puedan orientar programas y acciones de salud y nutrición para atender a esta población de forma prioritaria(AU)

The double burden of malnutrition and excess weight (or poor nutrition) is one of the indicators that best illustrates the health inequities that exist in indigenous areas of Mexico. On the other hand, there is scarce evidence of the nutritional status of the Tarahumara population. Objective: To estimate indicators of the nutritional status and its association with sociodemographic factors in the Tarahumara indigenous population under 5 years of age. Methods: A cross-sectional study in 21 indigenous localities of the Sierra Tarahumara in Chihuahua, Mexico, which analyzed sociodemographic, health and anthropometric information in children from 6 to 59 months of age (n=323). Anthropometric indices and their association with variables of interest was estimated by multiple logistic regression. A value of p ≤0.05 was considered statistically significant. All analyzes were performed using the Stata v14.2 statistical package. Results: It were founded high prevalences of short stature (44.4%), emaciation (5.3%), underweight (11.9%) and overweight (15.2%). Male sex was significantly associated with short stature (Odds Ratio (OR) = 2.5; 1.45-4.34), while no education of the mother (OR = 0.39; 0.15-0.99) and being a beneficiary of a local nutrition program for more than 2 years it was associated with being overweight (OR = 2.97; 1.26-6.97). Conclusion: Indicators of malnutrition and overweight were founded in the sample studied; these findings suggest inequity and delays in health and nutrition of the indigenous Tarahumara child population. More research is required that can guide health and nutrition programs and actions to serve this indigenous population as a priority(AU)

Abstract: Objective. To update the prevalence of infant and young child feeding indicators (IYCFI) in children under 24 months in Mexico. Materials and methods: Ensanut 2018-19 national representative survey with probabilistic design. Population: Women 12-59 years and their children <24 months. The indicators proposed by the World Health Organization were assessed by sociodemographic variables of the mothers using the sample design. Wald's test was used to compare between categories. Results: The prevalence of exclusive breastfeeding in children under six months was 28.3%, 42.9% of children under 12 months consumed infant formula and 29% continued breastfeeding at two years. Around 30% of children between 6 and 11 months did not meet the recommended minimum dietary diversity and only 49.4% consumed iron-rich foods. Conclusions: There are improvements in breastfeeding practices in Mexico, although the figures are low. The coordinated contribution from all sectors of society is required to improve infant feeding practices.

An Iterative Process for Training Design and Implementation Increased Health Workers' Knowledge for Taking Nutrition Behavior Change to Scale.

BACKGROUND: The shortage of skilled, motivated, and well-supported health workers is a major barrier to scaling up nutrition interventions and services. OBJECTIVE: The objective of this study is to describe the process for developing and implementing a training of health personnel for the delivery of the Integrated Strategy for Attention to Nutrition (EsIAN), an evidence-based strategy for promoting infant and young child feeding through primary health care in Mexico. The specific objective is to provide a case study and highlight challenges, as well as elements to successfully mitigate these, and discuss potential applications of findings beyond the Mexican context. METHODS: The design and implementation of training followed a 5-phase process: situation analysis, formative research, large-scale feasibility study, redesign and scale up, and evaluation. We conducted document reviews, surveys, and focus groups during the first phases to inform and refine the training, as well as a pre- and posttraining telephone survey to evaluate change in knowledge. RESULTS: The initial phases of the design provided a clear understanding of the opportunities and challenges for promoting infant and young child feeding, as well as health workers' routines and practices, which informed training design. The feasibility study allowed tailoring and refinement of training. The vertical coherence and coordination between the federal and state levels during redesign and scale up facilitated compliance with training timeline and process. Evaluation results showed significant improvement in knowledge posttraining of up to 19 percentage points. CONCLUSIONS: The EsIAN training component for health providers was developed using a systematic approach to consolidate and generate relevant evidence, following an iterative process to test, learn, and improve both design and implementation. This process allowed for flexibility to take advantage of new opportunities and respond to findings from iterations. Garnering and ensuring political support allowed for continuity and sustainability of actions.

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)

Representaciones sociales relacionadas con la alimentación escolar: el caso de las escuelas públicas de la Ciudad de México / Social representations linked to school feeding: the case of public schools in Mexico City

México está confrontando una epidemia de sobrepeso/obesidad sin precedentes, en particular entre los niños. El objetivo de este trabajo fue identificar las principales representaciones sociales relacionadas con la alimentación en la escuela, presentes en los discursos de los diferentes actores escolares. Se realizaron 20 entrevistas con actores escolares y 10 grupos de discusión con niños y niñas de 12 escuelas. Se identificaron tres principales concepciones, representaciones en las que estructuran su relación con la alimentación en la escuela: 1) comida "chatarra" versus comida casera; 2) valoración de la fruta desde diferentes perspectivas; 3) función placentera de la comida escolar. Se argumentará la contribución de esta información para entender mejor la oferta y el consumo de los escolares. El estudio permitió identificar algunos elementos que estructuran profundamente la relación de los diferentes actores escolares con la alimentación escolar y que se relacionan con: 1) presencia en los discursos de ideas y conocimientos sobre la alimentación, a veces opuestos y generados por diferentes campos de saberes, que muestran el carácter dinámico y complejo del hecho alimentario; 2) interiorización por parte de los niños de un sistema de jerarquización de los alimentos; 3) carácter identitario de la alimentación.

Mexico is facing an unprecedented epidemic of obesity and overweight, especially among children. This paper seeks to identify the main social representations related to school meals present in the discourse of different actors within the schools. Twenty interviews with school staff and ten discussion groups with boys and girls from 12 schools were conducted. Three main conceptions were identified in relation to school meals: 1) junk food vs. homemade food; 2) different perspectives on the importance of eating fruit; and 3) the enjoyment experienced while eating at school. The contribution of this information towards a better understanding of the mealtime supply of the schools and the demand of the students is discussed. This study also permits the identification of certain elements which profoundly structure the relationships of different school actors to school feeding, which are based on: 1) Ideas about nutrition generated by different and sometimes contradictory fields of knowledge, demonstrating the dynamicity and complexity of the practice of eating: 2) children's understandings about how to classify and prioritize foods; and 3) the connections between food and cultural identity.
