RESUMO
Childhood obesity is a major public health challenge. Previous research has identified the impact of school-based interventions for preventing and treating obesity; we hypothesized that when curricular changes are integrated, results could be exponentiated. This study aimed to systematically review and conduct a meta-analysis of the published literature analyzing information about school-based interventions inserted in the curriculum. The Cochrane Handbook methodology was followed. An electronic search was conducted in five databases, with a specific design strategy per database. Randomized controlled trials or quasi-experimental studies of children with nutrition and physical activity (PA) interventions inserted into the school curricula were included. The risk of bias was assessed with the Risk of Bias tool. The mean differences were pooled using a fixed-effects model for the meta-analysis. The certainty of the evidence was evaluated according to the guidelines of the Grading of the Recommendations, Assessment, Development, and Evaluations working group (Protocol ID: CRD42021270557). After the screening and selection process, 12 studies were included. The interventions identified, based on the school curricula, include classroom activities and homework, among others. A meta-analysis with five intervention groups presented an overall mean difference of -0.14 body mass index (BMI) Z-score (95% CI: -0.25, -0.03) after this intervention with high certainty of the evidence. This systematic review and meta-analysis suggest that nutrition and PA lessons inserted into the curricula and supported with additional activities (i.e. homework, workshops, etc.) could increase nutrition knowledge and improve attitudes toward fruit, vegetables, and water consumption, and BMI Z-score reduction.

OBJETIVO: Describir el proceso para diseñar una estrategia de comunicación con el fin de promover el uso del etiqueta-do frontal de advertencia (EFA) y la selección de alimentos saludables en niños, niñas y adolescentes (NNA) mexicanos. Material y métodos. Estudio de cuatro fases con esco-lares, adolescentes y cuidadores: 1) investigación formativa (18 grupos focales, n= 179); 2) talleres de cocreación con NNA (n= 33); 3) diseño de la estrategia, con base en el modelo de comportamiento COM-B; y 4) prueba piloto (seis grupos focales, n= 52). RESULTADOS: La estrategia de comunicación debería mejorar la comprensión del EFA y los conocimientos sobre la relación de los ingredientes críticos (calorías, grasas saturadas, grasas trans, sodio, edulcorantes y cafeína) y la enfermedad; asimismo, debería resaltar las consecuencias positivas de una alimentación saludable y las negativas del consumo excesivo de alimentos con sellos, así como destacar que los alimentos naturales tienen un menor costo y mejor calidad que los alimentos con sellos; se deben ofrecer sugerencias de preparaciones atractivas y saludables con alimentos naturales. Conclusión. La investigación formativa y la participación de NNA en la creación de la campaña fueron esenciales para diseñar una estrategia cultu-ralmente pertinente con potencial de impacto. El proceso y los resultados del estudio podrían informar sobre esfuerzos en contextos parecidos al de México.

OBJETIVO: Analizar el rol de los factores socioeconómicos y culturales en la vulnerabilidad a la obesidad en madres y sus hijos menores de dos años, en localidades del Sur de Morelos, México. Material y métodos. Se realizó trabajo de campo y observación no participativa. Durante 2019, se aplicaron 17 entrevistas semiestructuradas a una submuestra de una cohorte. Los datos fueron ordenados y analizados con apoyo del software Atlas-Ti v. 7, usando 18 códigos libres. RESULTADOS: Factores sociales como los ingresos del hogar y los roles de género, combinados con la influencia de la parentela y las creencias sobre la preferencia de la niñez por productos ultraprocesados, predisponen la disponibilidad de bebidas y alimentos calóricos que generan vulnerabilidad a la obesidad durante la infancia temprana. La actividad eco-nómica de las madres, la participación de los padres y evitar influencia de parientes puede predisponer una mejor calidad de los alimentos y mayor actividad física. CONCLUSIONES: La baja disponibilidad de alimentos saludables, los riesgos de inseguridad alimentaria y los factores familiares y culturales, que se presentan en contextos de vulnerabilidad económica y social, incrementan la vulnerabilidad del binomio madre-hijo a la obesidad.

Validated measures predicting infant consumption of nutrient supplements or fortified foods are essential for the success of nutritional interventions to improve undernutrition. Behavioural coding of food acceptance is one promising approach, though the required time and resources are limiting. The overarching goal of the present study was to adapt a video coding (VC) protocol for use as a live coding (LC) method to assess infant food acceptance in naturalistic settings. Infants (n = 59; ages 7-24 months) were fed a small-quantity lipid-based nutrient supplement (SQ-LNS) mixed with a familiar food by caregivers in the State of Morelos, Mexico. Trained coders used a VC scheme to rate infant acceptance of each spoon offer using a 4-point scale. The VC scheme was subsequently adapted for use as an LC method to be used in participant homes and a video live coding (VLC) method to monitor reliability. Reliability and validity of the LC method were tested in a subsample of dyads (n = 20). Intraclass correlation coefficients (ICCs) indicated that the inter-rater reliability between coders using the LC method was moderate or good when compared to VC methods (ICCs = 0.75 and 0.87). Live coded acceptance scores were also moderately associated with consumption of the SQ-LNS (ρ = 0.50, p = 0.03). The LC scheme demonstrated initial reliability and validity as an assessment of infant food acceptance. Since VC is both resource and time-intensive, the LC scheme may be useful for assessing infant food acceptance in resource-limited settings.

School-based physical education (PE) is part of a whole-of-school approach to promote physical activity and its benefits for health. However, there are important gaps between the design and implementation of PE policies. This study aimed to describe the implementation fidelity and feasibility of school-based PE policies in Mexico. Data on implementation fidelity and feasibility was collected using semi-structured interviews (n = 17) and focus groups (n = 11) with high- (n = 7) and local-level (n = 122) stakeholders. We conducted a qualitative and triangulation content analysis. Feedback sessions were carried out with some participants. Barriers for implementation fidelity and feasibility of PE policies included inconsistencies in the time allocated to PE across schools and regions in the country; inconsistencies between teachers' planning of PE classes and the actual class; a wide diversity of professional profiles among PE teachers; a limited number of PE professors, materials and facilities. To address these situations, some PE teachers were able to modify lesson plans and to design PE materials made from recycled materials. In conclusion, the current way in which school-based PE policies are being implemented in Mexico hinder PE from playing a major role in promoting physical activity among children and adolescents.

The risk of anaemia in adolescence increases due to accelerated growth. This study aims to: (1) estimate the prevalence of anaemia in 2012 and 2018-2019 (Encuesta Nacional de Salud y Nutricion - ENSANUT [n = 5841 in 2012 and n = 2380 in 2018-2019]) in non-pregnant, Mexican adolescent women aged 12-19 years, and the changes in prevalence over this period according to sociodemographic, health and nutrition characteristics; (2) estimate the associations between anaemia and sociodemographic, health and nutrition characteristics in each year and overall, in non-pregnant Mexican adolescent women. Anaemia was defined as capillary haemoglobin <12 g/dL. The distribution of characteristics and their changes between 2012 and 2018-2019 were described. The covariate-adjusted prevalence of anaemia in 2012 and 2018-2019 and the changes over that period were estimated from a multiple log-binomial regression model and the factors associated with anaemia were assessed in each survey year and in both years combined. The prevalence of anaemia was 7.7% in 2012 and 13.1% in 2018-2019 (69% increase, Prevalence Ratio: PR = 1.69; 95%CI: 1.35, 2.13). The covariate-adjusted prevalence of anaemia increased from 6.9% to 10.5% in the overall population (PR = 1.53, 95%CI: 1.19, 1.96), and increased considerably in the age group 12-14 years (PR = 1.94, 95%CI: 1.36, 2.75), and in the northern region (PR = 3.68, 95%CI: 2.55, 5.32). Those receiving iron supplements or school breakfasts did not register a significant increase. A higher household wellbeing status and older age were associated with a lower prevalence of anaemia. Anaemia in non-pregnant adolescent women continues to be a public health problem. To improve the development and health of adolescent women in Mexico and to pave the way to a healthy pregnancy for the next generation, the causes of anaemia should be identified.

Front-of-pack labeling (FOPL) is a tool that enables consumers to compare foods and select healthier options. Due to low understanding of the Guideline Daily Amount (GDA) labeling among Mexicans, a law was implemented in October 2020 that modified the FOPL to a warning labeling (WL) system. The purpose of this study was to compare the perception and understanding of GDA and WL during the law modification period. We conducted a panel design with two measurements: (1) using GDA label (September 2020) and (2) using WL (October-November). We estimated differences in GDA vs. WL through multinomial logistic regression models and changes were measured through predictive margin contrasts and Wald tests. When comparing the same products with different labels, the participants reported that it would be unlikely/very unlikely that they would consume products packaged with the WL (81.5%; 95%CI: 79.2, 83.8) compared to those with GDA (24.2%; 95%CI: 21.7, 26.7). Consumers' perception was that the quantities of packaged products they should consume was small or very small when they used the WL (93.8%; 95%CI: 92.4, 95.5) compared to GDA (41.6%; 95%CI: 39.7, 44.6). When comparing food groups, participants were more confident about choosing healthy products when using the WL compared to the GDA. During the implementation of WL in Mexico, the studied population had a better perception and understanding of less healthy packaged foods when using WL, compared to the GDA label.

The contributions of processed foods to the overweight and obesity problem in Latin America are well known. Engagement with the private and public sectors on possible solutions requires deeper insights into where and how these products are sold and the related implications for diet quality. This article characterizes the diversity of wheat and maize processed foods (WMPFs) available to consumers in Mexico City. Data were gathered across nine product categories at different points of sale (supermarkets, small grocery stores, convenience stores) in high and low socioeconomic (SE) areas. We assessed WMPFs based on Nutri-Score profile, price, and health and nutrition claims. Roughly 17.4% of the WMPFs were considered healthy, of which 62.2% were pastas and breads. Availability of healthy WMPFs was scarce in most stores, particularly in convenience stores Compared to supermarkets in the low SE area, those in the high SE area exhibited greater variety in access to healthy WMPFs across all product categories. In the low SE area, healthy WMPFs were priced 16-69% lower than unhealthy WMPFs across product categories. The extensive variety of unhealthy WMPFs, the limited stock of healthy WMPFs in most retail outlets, and the confusing health and nutrition claims on packaging make it difficult for urban consumers to find and choose healthy WMPFs.

The prevalence of obesity and overweight in Mexican children and adolescents is high (greater than 30%) and lifestyle behaviors are far from achieving health recommendations. Salud Escolar is a complex cross-sectoral multi-level policy-based program in Mexico aiming to support schoolchildren healthy behaviors. We describe the rationale, design and methods for the comprehensive evaluation of Salud Escolar during its first phase of implementation. Using a mixed-methods approach and the logic model of Salud Escolar as a guide, a comprehensive evaluation involving 3 types of evaluations was designed: 1) A design evaluation before program implementation, to determine the consistency between the design of Salud Escolar and the problem to be addressed (i.e., childhood obesity), 2) An implementation evaluation to assess potential execution bottlenecks, and 3) An outcomes evaluation, to measure short-term (i.e., knowledge, attitudes and practices related to healthy eating, drinking plain water and doing regular physical activity) and intermediate outcomes (i.e., fruit and vegetable intake, water consumption and daily moderate to vigorous physical activity). This evaluation will provide essential knowledge about program design and implementation processes, which are vital for drawing robust conclusions about the effectiveness of the program. Results and lessons learned from this comprehensive evaluation will provide evidence to improve Salud Escolar program and facilitate its upscaling process and may provide relevant information for school-based programs in other places sharing socio-contextual conditions.
RESUMO
BACKGROUND: Quality physical education (QPE) is part of a whole-of-school approach for school-based physical activity promotion. The United Nations Educational, Scientific and Cultural Organization QPE Policy Project supported 4 countries to develop QPE policies. The authors summarize the process, progress, successes, setbacks, and lessons learned during the implementation of the project in Mexico. METHODS: The project was developed from August 2016 to April 2018 following the methodology proposed by the United Nations Educational, Scientific and Cultural Organization. Adaptations to the methodology were made to meet local needs. RESULTS AND DISCUSSION: The project successfully implemented the United Nations Educational, Scientific and Cultural Organization methodology and prepared a national strategy for the provision of QPE in Mexico. The national strategy progressed despite the change in presidential administration. Successes included the use of a QPE policy evaluation framework, the inclusion of stakeholders representing extreme PE views and from all regions in the country, and the presence of international agencies in the national team. Setbacks included difficulties in engaging key organizations and a weak communication campaign. Lessons learned are discussed. CONCLUSIONS: The QPE project in Mexico served as a pilot project to test the feasibility of implementing a QPE policy revision process. The experience and lessons learned in Mexico can be drawn on to inform the work of other stakeholders interested in advocating for a national QPE policy.
RESUMO
Small-quantity lipid-based nutrient supplements (SQ-LNS) could help prevent malnutrition. Our primary objective was to examine the acceptability and consumption of sweetened and unsweetened versions of SQ-LNS before and after 14-days of repeated exposure. A total of 78 mother-infant dyads recruited from health centers in Morelos, Mexico, were randomized to two groups of SQ-LNS (sweetened, LNS-S; unsweetened, LNS-U). During the study, infants were fed SQ-LNS (20 g) mixed with 30 g of complementary food of the caregiver's choice. The amount of supplement-food mixture consumed was measured before, during and after a 14-day home exposure period. We defined acceptability as consumption of at least 50% of the offered food mixture. At initial exposure, LNS-U consumption was on average 44.0% (95% CI: 31.4, 58.5) and LNS-S 34.8% (25.3, 44.0); at final exposure, LNS-U and LNS-S consumption were 38.5% (27.8, 54.0) and 31.5% (21.6, 43.0). The average change in consumption did not differ between the groups (2.2 p.p. (-17.2, 24.4)). We conclude that the acceptability of sweetened and unsweetened SQ-LNS was low in this study population. Since consumption did not differ between supplement versions, we encourage the use of the unsweetened version given the potential effects that added sugar may have on weight gain especially in regions facing the double burden of malnutrition.

Front-of-pack labeling is a cost-effective strategy to decrease population consumption of sodium, sugar, saturated fat, total fat, and trans-fatty acids, considered critical nutrients for chronic disease. Our main objective was to explore the subjective understanding of labels that are currently used internationally among low- and middle-income Mexican consumers. We performed two phases of 10 focus groups with adolescents (13-15 y), young adults (21-23 y), mothers of children 3-12 y, fathers of children 3-12 y and older adults (55-70 y). Seven FOPL were evaluated: Guideline Daily Amounts, Multiple Traffic Light, Chilean Warning labels, Warning labels in Red, 5-Color Nutrition Label, Health Star Rating, and Healthy Choice label. Data was analyzed with a triangulation of researchers using a content analysis, based on three codes: 1) awareness and use of the Guideline Daily Amounts, 2) acceptability, and 3) subjective understanding of labels. Most participants were aware of the Guideline Daily Amounts, however they rarely used it because interpreting the information displayed on the label was too complicated. Health Star Rating, Warning labels, Multiple Traffic Light and the Healthy Choice logo labels were the most understandable, however the acceptability of the The Healthy Choice logo decreased as it did not provide information on specific ingredients. The Warning labels was the only label able to warn about critical nutrients that could represent a health risk. The Warning labels in red was more accepted compared to Warning labels in black. Results show that directive and semi-directive labels, such as Warning labels, Health Star Rating or Multiple Traffic Light, may be better at helping population of low- and middle income make healthier food choices, than non-directive FOPL such as the Guideline Daily Amounts implemented in México. The study results highlight the potential of Warning labels to support decreases in the consumption of critical ingredients in low- and middle-income Mexican consumers.

Abstract: Objective: To evaluate the nutrient profile and marketing techniques (MT) of processed wheat and maize foods (PWMF) sold in food retail outlets of Mexico City. Materials and methods: We collected information on nutrient content and MT for PWMF across twelve food categories from 58 retail outlets in high and low income areas of Mexico City. Results: Roughly 8.5% and 10.7% of PWMF, in low and high income areas were healthy, respectively. The ≤12% of PWMF were healthy, except for flours (~33%) and pastas (≥95%). Across both income areas, 28.3%-31.9% of WMPF employed characters, 46.5%-50.1% promotions and 38.2%-41.3% claims. A significant association (p<0.001) was found between the use of MT and unhealthy PWMF in both areas. Conclusion: The majority of PWMF available in the food retail sector were considered unhealthy, which were being more offered in low income areas. Across income areas, the majority of unhealthy WMPF employed MT to encourage consumption.
RESUMO
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)

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)
