An Iterative Process for Training Design and Implementation Increased Health Workers\u27 Knowledge for Taking Nutrition Behavior Change to Scale

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\u27 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

Desnutrição materna e antropometria nos filhos adultos: coorte de nascimentos de 1982, Pelotas, Brasil

O presente estudo investigou a relação entre a nutrição de mães e do seus filhos nascidos em Pelotas no ano de 1982 e que foram acompanhados até os 23 anos de idade. Entre os achados mais importantes do estudo, encontrou-se que os filhos de mães muito magras e baixinhas não apresentaram maior chance de ocorrência de obesidade na idade adulta. Por outro lado, mães que apresentavam sobrepeso ou obesidade antes da gestação tiveram filhos com maior peso em relação à altura e também maior quantidade de gordura na região da cintura aos 23 anos. Atualmente a obesidade apresenta-se como um dos principais problemas de saúde da população em geral, sendo também observado na população mais pobre. De acordo com os resultados deve-se buscar esclarecer às mulheres em idade reprodutiva que o seu estado de nutrição no momento de engravidar é também importante para a saúde e nutrição dos seus filhos ao longo da vida. Sendo assim, as mulheres devem ser orientadas a atingir um peso adequado para a sua altura antes de experimentar a primeira gravidez

Talla baja y sobrepeso en menores de 5 años que habitan la Sierra Tarahumara, México

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.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

Evaluación de procesos de una intervención: actividad física durante el embarazo y postparto

Objective: To evaluate the process of an intervention on physical activity during pregnancy and postpartum. Methods: In the context of a social program that fights extreme poverty, the beneficiaries (n=927) receive an intervention that consists of the promotion of the practice of physical activity, through counseling, workshops, and educational materials. During 2008-9, 2010 and 2012, we visited health units from urban and rural areas, randomly selected from four states of Mexico. Health service providers collected process data during observation of consultations and through the application of questionnaires to the beneficiaries. Four indicators of implementation of the intervention were studied: fidelity to the planned activities, dose delivered to the population, scope of the target population, and reception of the intervention by pregnant women and postpartum women. Results: Health units were visited in the initial (n=91), intermediate (n=47), and final (n=82) stages of the study. The delivered dose showed an implementation level of 81-86%. Fidelity hadObjetivo: Evaluar los procesos de una intervención de actividad física durante el embarazo y postparto.

Green Space Exposure and Obesity in the Mexican Adult Population

Green space or natural vegetation may reduce obesity risk by increasing opportunities for physical activity or reducing stress and exposure to other pollutants. Obesity prevalence in Mexico is ranked among the highest in the world. However, research on the association between green space and obesity in Mexico is lacking. We used data from the National Nutrition Survey in Mexico (2018–2019), a nationally representative sample of Mexican adults. The analytical sample included participants between 20–59 years of age (n = 12,631). We assessed exposure to green space using a 30 m resolution Landsat satellite Normalized Difference Vegetation Index (NDVI) from 2018. Linear regression models examined associations between NDVI and body mass index (BMI), adjusting for confounders. The mean age of the study sample was 38 (SD 0.19) years. Participants living in areas with the highest green space exposure had the lowest education level (53.51%) and socioeconomic status (28.38%) and were located in central (33.01%), south (30.37%), and rural areas (21.05%). Higher residential exposure to green space was associated with a mean decrease in BMI of −1.1 kg/m2 (95% CI: −1.59, −0.68). This is one of the first studies in Latin America to suggest a protective association between green space and obesity among Mexican adults

Methodologies for Monitoring the Digital Marketing of Foods and Beverages Aimed at Infants, Children, and Adolescents (ICA): A Scoping Review

While television has been the most widely used medium for food and beverage marketing, companies are shifting in favor of digital media. The ubiquitous digital marketing of breast-milk substitutes (BMS) and foods and beverages high in saturated fat, salt, and/or free sugars (FBHFSS) has been considered a powerful environmental determinant of inadequate dietary practices during infancy, childhood, and adolescence. The scoping review’s aim was to systematically identify and map the types of methodologies available to monitor the digital marketing of foods and beverages targeting infants, children, and adolescents (ICA) worldwide. Research evidence published from 2011 to October 2021 was examined using search strategies including multiple databases and citation tracking. A total of 420 sources were evaluated, and 28 studies from 81 countries meeting the inclusion criteria were retained. Most of the studies (n = 24) documenting methodologies to monitor inappropriate digital marketing were published since 2015 and were primarily aimed at identifying the promotional techniques and nutritional content of FBHFSS targeting adolescents (n = 13). It is paramount to develop a feasible and scalable monitoring system to develop effective policies to protect parents and ICA from BMS and FBHSFF digital marketing

Barreras y facilitadores para actividad física durante el embarazo y posparto en mujeres pobres de México

Objetivo. Explorar percepciones de proveedores de salud y beneficiarias del Programa Oportunidades sobre la práctica de actividad física durante el embarazo y posparto, e identificar características de la consejería sobre el tema en el primer nivel de atención en salud. Material y métodos. Estudio de métodos mixtos que forma parte de una intervención en nutrición del Programa Oportunidades. La información cualitativa se colectó por entrevista (50 mujeres; 34 proveedores de salud) y se obtuvo información cuantitativa a partir de un cuestionario (n=88 mujeres; n=64 proveedores; n=111 observaciones de consulta). Resultados. Se documentaron barreras a) individuales: falta de tiempo y de apoyo social; b) socioculturales: prejuicios de pares y familiares, y falta de instructores, y c) ambientales: falta de espacios físicos seguros y apropiados. 38% de las mujeres reporta haber recibido consejería sobre el tema versus 63.4% de proveedores que reportan haberla dado (p=0.002). Conclusiones. Urgen capacitación a proveedores y promoción de la actividad física que eliminen los prejuicios asociados al tema durante el embarazo y posparto

Evolution of social food assistance programs in Mexico through Ensanut MC 2016 data

Objective. To describe the coverage and targeting of Social Food Assistance Programs (SFAP) in Mexico. Materials and methods. Data were obtained from 9 137 households of the Halfway National Health and Nutrition Survey 2016 (Ensanut MC 2016) who receive SFAP. The distribution of the SFAP by place of residence, index of socioeconomic status and SFAP relevance were analyzed. Results. 44% of households receive some SFAP, with a higher concentration in indigenous households (70%), a very low socioeconomic level (70%), and moderate and severe food insecurity. The SFAP with the greatest coverage were Prospera (21%), Liconsa (9%), School Breakfasts Program (17%) and the Support Program for Older Adults; of these the best-focused program was Prospera. Conclusions. It is necessary to review the resources of the programs and direct them to the population with greater deficiencies and greater nutritional vulnerability
