RESUMEN
OBJECTIVE: This study aims to investigate the factors that promote or hinder the feeding of children with minimal or no ultra-processed products to inform the design of an mHealth strategy in Mexico and prevent child malnutrition among the economically vulnerable. METHODS: An exploratory qualitative study was conducted, involving 24 in-depth face-to-face interviews with caregivers of children aged 24-59 months from both urban and rural communities. To analyze the data, we used thematic analysis and incorporated a few elements of grounded theory. RESULTS: More barriers than facilitators were identified. Key barriers included: misconceptions and the widespread availability of junk food through an extensive network of grocery stores; neighbors and family gifting junk food; the association of soda with celebrations; the practice of indulging children with junk food; and the normalization of junk food consumption by both adults and children. Facilitators included: caregivers' awareness of the health risks associated with junk food; economic constraints limiting junk food purchases; support from husbands in regulating children's junk food consumption; the presence of a family member with diabetes; specific cultural beliefs about children's digestive health; as well as displacement of "healthy" foods that nourish children. CONCLUSION: Based on our findings, we formulated recommendations for interventions at intrapersonal, interpersonal, organizational, community, and public policy levels to support healthier feeding practices for children.
RESUMEN
BACKGROUND: COVID-19 virus was reported to be transmitted through breastfeeding (BF), creating the need for rapidly available, standardized information and training for health personnel and the community about BF as an urgent action to reduce misinformation and unethical promotion of breast milk substitutes (BMS). In Mexico, a massive open online course (MOOC) was designed and implemented to protect, promote and support BF in emergency contexts. METHODS: MOOC registration consisted of collection of quantitative data regarding participant characteristics, MOOC coverage, scores achieved and completion rates. A multiple linear regression analysis was performed to relate the absolute and relative skills earned in the MOOC to participant characteristics. In addition, factors associated with completion rate and dissemination of information from the MOOC were analyzed using multiple logistic regression and presented as odds ratios. RESULTS: During a period of 19 months, 52,426 participants across the country, including health personnel and general population, entered the Cursos en Linea del Instituto Mexicano del Seguro Social (CLIMSS) platform, of which 50.5% completed the MOOC. The level of participation was maintained from January 2021 to early 2022 when the perception of the risk of getting sick from COVID-19 and quarantining decreased. In adjusted analysis, completion rate was associated with being older or belonging to a health institution; furthermore, residing in the north of the country doubled the odds of completing the MOOC (odds ratio 2.24; 95% confidence interval 1.95-2.56). CONCLUSIONS: A MOOC can be a useful training strategy to disseminate information, especially in emergencies where physical distancing is important and reaching the largest possible population is required.
RESUMEN
BACKGROUND: Promoting physical activity (PA) and healthy feeding (HF) is crucial to address the alarming increase in obesity rates in developing countries. Leveraging mobile phones for behavior change communication to encourage infant PA and promote HF is particularly significant within the Mexican context. OBJECTIVE: This study aims to explore the effectiveness and feasibility of mHealth interventions aimed at promoting PA and HF among primary caregivers (PCs) of Mexican children under the age of 5 years. Additionally, the study aims to disseminate insights gained from intervention implementation amidst the COVID-19 pandemic and assess the potential of behavior change mHealth interventions on a broader population scale. METHODS: NUTRES, an mHealth intervention, underwent an effectiveness-implementation hybrid trial. Over 36 weeks, participants in the intervention group (IG), totaling 230 individuals, received approximately 108 SMS text messages tailored to their children's age. These messages covered topics such as PA and HF and emphasized the significance of proper child nutrition amidst the COVID-19 pandemic. NUTRES participants were recruited from both urban and rural health units across 2 states in Mexico. Given the COVID-19 context, both baseline and follow-up surveys were conducted via mobile or fixed telephone. The evaluation of effectiveness and implementation used a mixed methods approach. Qualitative analysis delved into participants' experiences with NUTRES and various implementation indicators, including acceptance, relevance, and coverage. Grounded theory was used for coding and analysis. Furthermore, difference-in-differences regression models were used to discern disparities between groups (comparison group [CG] versus IG) concerning knowledge and practices pertaining to infant PA and HF. RESULTS: Of the total 494 PCs enrolled in NUTRES, 334 persisted until the end of the study, accounting for 67.6% (334/494) participation across both groups. A majority of PCs (43/141, 30.5%, always; and 97/141, 68.8%, sometimes) used the SMS text message information. Satisfaction and acceptability toward NUTRES were notably high, reaching 98% (96/98), with respondents expressing that NUTRES was "good," "useful," and "helpful" for enhancing child nutrition. Significant differences after the intervention were observed in PA knowledge, with social interaction favored (CG: 8/135, 5.9% vs IG: 20/137, 14.6%; P=.048), as well as in HF practice knowledge. Notably, sweetened beverage consumption, associated with the development of chronic diseases, showed divergence (CG: 92/157, 58.6% vs IG: 110/145, 75.9%; P=.003). In the difference-in-differences model, a notable increase of 0.03 in knowledge regarding the benefits of PA was observed (CG: mean 0.13, SD 0.10 vs IG: mean 0.16, SD 0.11; P=.02). PCs expressed feeling accompanied and supported, particularly amidst the disruption of routine health care services during the COVID-19 pandemic. CONCLUSIONS: While NUTRES exhibited a restricted impact on targeted knowledge and behaviors, the SMS text messages functioned effectively as both a reminder and a source of new knowledge for PCs of Mexican children under 5 years of age. The key lessons learned were as follows: mHealth intervention strategies can effectively maintain communication with individuals during emergencies, such as the COVID-19 pandemic; methodological and implementation barriers can constrain the effectiveness of mHealth interventions; and using mixed methods approaches ensures the complementary nature of results. The findings contribute valuable evidence regarding the opportunities and constraints associated with using mobile phones to enhance knowledge and practices concerning PA and HF among PCs of children under 5 years old.

OBJECTIVE: To explore the perceptions, knowledge, and practices of breastfeeding in the context of Covid-19 of pregnant and postpartum women, midwives, and health providers in an indigenous region of Chiapas, Mexico. MATERIALS AND METHODS: Qualitative thematic analysis study involving semi-structured interviews (n = 46) with pregnant women (n = 19), postpartum women (n = 6), health providers (n = 10, i.e., doctors/nurses), and midwives (n = 11). RESULTS: Among mothers, 47% (n = 11) did not know if Covid-19 is transmitted through breastfeeding. They mentioned that they would stay away from their newborns if infected. Health providers and midwives have not received education or any supporting material on the value of breastfeeding during Covid-19 infection. CONCLUSION: Breastfeeding mothers' promotion and counseling remain poor in indigenous communities and have worsened during the Covid-19 pandemic. Breastfeeding training among health providers and midwives should be provided or strengthened even more in emergency situations.

OBJETIVO: Describir la tendencia en las prácticas de alimentación infantil en México antes y después de la pandemia por Covid-19, usando datos de la Encuesta Nacional de Salud y Nutrición (Ensanut) 2012, 2018-19, 2021 y 2022. Material y métodos. Población: mujeres 12-59 años y sus hijos/as < 24 meses. Se calcularon los indicadores de alimentación infantil según la Organización Mundial de la Salud 2021. Se realizaron modelos de regresión logística para analizar tendencias entre encuestas ajustando por variables sociodemográficas, considerando el diseño muestral. Se muestran las tendencias de lactancia materna (LM) y fórmula comercial infantil (FCI) por área urbano/rural y ocupación de la madre. RESULTADOS: La prevalencia ajustada de LM exclusiva en niñas/os menores de seis meses aumentó (14.8% en 2012; 28.6% en 2018-19 y 33.6% en 2021-22; p<0.001). El consumo de FCI en niñas/os < 12 meses se redujo de 62.8 a 42.8% entre 2012 y 2018-19 y permaneció en 43.3% en 2021-22 (p<0.001). CONCLUSIONES: Las prácticas de alimentación infantil mejoraron principalmente entre 2012 y 2018-19, y la tendencia positiva se desaceleró en 2021-22.
RESUMEN
OBJETIVO: Estimar prevalencias de indicadores de prácticas de alimentación infantil en menores de 24 meses en México. Material y métodos. Análisis de la Encuesta Nacional de Salud y Nutrición Continua 2021 y 2022 (Ensanut Continua 2021 y 2022) en mujeres de 14-59 años y sus hijos/as menores de 24 meses (<24 meses). Se calcularon los indicadores ajustando por diseño muestral de las encuestas. RESULTADOS: El 33.6% de niñas/os <6 meses recibió lactancia materna exclusiva (LME). El 27.2% de niñas/os <24 meses no recibió LME durante los primeros tres días de vida y fue alimentado con fórmula comercial infantil (FCI) u otro líquido. El 42% de niñas/os de entre 6 y 23 meses consumió alimentos no saludables. CONCLUSIONES: Las prácticas de alimentación infantil en México deben ser protegidas mediante políticas que regulen la comercialización de FCI y promuevan un entorno laboral, social y político propicio para la lactancia materna y el cuidado infantil, para que madres, padres y cuidadores puedan adoptar prácticas de lactancia y alimentación complementaria adecuadas.
RESUMEN
A massive incorporation of ultra-processed products into young children's diets worldwide and in Mexico has been documented. The aim of this study is to understand the role of sociocultural factors in principal caregivers' decisions to give a type of ultra-processed food to children under age five, called 'comida chatarra' ('junk food' in English), usually includes sugar-sweetened beverages, sweet and salty snacks, and sweet breakfast cereals. We conducted a descriptive, observational qualitative study. The research was conducted in urban and rural communities in two Mexican states. Twenty-four principal caregivers were equally distributed between the two states and types of communities. They were interviewed in person. Phenomenology underpinned this study. Results highlight the preponderant role of culture in food choices and feeding practices with junk food. Local culture influences child-feeding with ultra-processed products through social norms, knowledge, or socially constructed attitudes. These social norms, built in the context of abundant ultra-processed products and omnipresent marketing, 'justify' children's consumption of junk food. They acquire these products from the principal caregivers, family members, and neighbors, among others, who reward and pamper them. These actors also define what amount (small amounts) and when (after meals as snacks) children are given these products. Cultural factors must be considered in the development of effective public policies and programs that aim to change the culture around ultra-processed products among children and avoid their consumption.

Innovative and continuously changing methods of digital marketing are routinely used to reach young women and their families with advertisements that normalise infant artificial feeding and undermine breastfeeding. Legislation and provisions regulating digital and social media marketing are limited across countries. The aim of this scoping review was to systematically identify and summarise worldwide legislation implemented to regulate breast-milk substitutes (BMS) marketing on digital and social media, as well as identifying areas of opportunity to strengthen and improve it. Documents published from January 2012 to April 2022 were examined using search strategies including multiple databases and citation tracking. A total of 127 sources were evaluated, and only 28 documents from 24 countries meeting the inclusion criteria were retained. Most of the reviewed documents explicitly stated that digital marketing was prohibited (n=23), as opposed to being regulated only, with prior approval from the relevant authorities in each country. Regarding monitoring, from the countries included in this scoping review, only 14 of 24 (58.3%) stipulate a monitoring process for compliance with legal measures and have designated an actor responsible for monitoring. In addition, 22 of 24 (91.6%) countries included have defined sanctions, but only 17 (70%) countries specify the entity responsible for enforcement. The results highlight the urgent call for the explicit regulation of BMS marketing in digital and social media worldwide, as well as the public documentation of such legal measures. Likewise, it is important that there are effective, transparent and free of commercial influence national monitoring systems used to ensure compliance with legal measures.

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.

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.

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)

Although actions have been taken to improve breastfeeding in Mexico, trends over the last decade and their associated factors have not been analysed. We estimated trends in breastfeeding practices at the national, rural/urban, and regional level indigenous ethnicity and socio-economic level, and their associated factors using the National Demographic Dynamics Survey (2006, 2009, 2014 and 2018). We assessed breastfeeding indicators of women with children <24 months according to The World Health Organization recommendations. Logistic regressions models of pooled data were used to estimate trends and associations with biological and sociodemographic characteristics. Between 2006 and 2018, the prevalence of ever breastfed increased from 91.8% to 94.2% (p < 0.001), whereas early initiation of breastfeeding increased from 40.8% to 59.7% (p < 0.001), with similar increments by urban/rural level. Between 2009 and 2018, the prevalence of exclusive breastfeeding in children <6 months increased from 13.0% to 20.7% (p < 0.001). The largest increase was seen in Mexico City, in nonindigenous women and those with a high socio-economic status, whereas indigenous women and those from the South had the lowest or no improvements. Breastfeeding education during pregnancy [odds ratio (OR) 1.3; 95% confidence interval (CI) 1.1-1.5] was positively associated with exclusive breastfeeding, whereas being employed (OR 0.8; 95% CI 0.6-0.9) was negatively associated. Breastfeeding practices improved but are still far from recommendations. Implementing strategies like breastfeeding counselling and programmes and policies that promote and support breastfeeding for poor, indigenous, single and working mothers should be a priority for the government to ensure that all children have the best start in life.

BACKGROUND: Evidence suggests that inadequate hospital practices, as well as sociocultural and community factors have detrimental effects on timely initiation as the first breastfeed within first hour after birth, and exclusive breastfeeding. The purpose of the study was to examine the factors that influence timely initiation of breastfeeding and exclusive breastfeeding at birth and 1 month postpartum in Mexican women delivering in public and private hospitals. METHODS: Mixed methods were conducted between May and July 2017, including surveys (n = 543) and semi-structured interviews (n = 60) in the immediate (7 h) and intermediate (30 days) postpartum periods. Participants were women aged 15-49 years, in public and private hospitals, of urban and rural municipalities of Chihuahua and Puebla, Mexico. RESULTS: Timely initiation was reported by 49.4% of mothers, and 34.7% reported that their children received infant formula at the hospital. Only 44.8% of women reported exclusive breastfeeding at 1 month postpartum. Timely initiation of breastfeeding was higher in women with vaginal delivery (62.1 vs 35.5%; p < 0.05) and those who received information during pregnancy (OR 1.07; p = 0.018). Exclusive breastfeeding at 1 month postpartum was related to older maternal age (OR 1.05; p < 0.001) and the fact that the mothers had received more information about breastfeeding during pregnancy (OR 1.13; p = 0.0001). Infant formula use was less associated with timely initiation (OR 0.46; p = 0.001). Participants in qualitative data identified the emotional, physical and economic benefits of breastfeeding, however, the perception about insufficient production of human milk, and the belief that infant formula is recommended, persists. CONCLUSIONS: Modification of hospital practices, such as decreasing the number of cesarean and the use of infant formula, as well as the support of the initiation and continuation of exclusive breastfeeding by health personnel and family members, could help increase breastfeeding practices in Mexican women.

AIM: We aimed to examine the advertising and marketing of breast milk substitutes (BMS) through the internet, social media and television in Mexico. METHODS: We recorded the programming of four main TV channels at peak times to identify BMS advertisements. In addition, we identified the main BMS products and companies present on the internet, as well as related home pages and social networks (Facebook, Twitter and YouTube). After that, we examined current BMS' marketing practices using the International Code of Marketing of Breast-milk Substitutes ('the Code') as a framework for ethical marketing. Qualitative and statistical analyses are presented. RESULTS: BMS manufacturers have a presence on television, social media and the internet. Violations of the Code, as well as promotional practices unforeseen by the Code, were identified in all the studied media. These include text and images idealising the use of BMS, as well as mechanisms for boosting sales and making contact with consumers. CONCLUSIONS: The Mexican population is exposed to BMS advertisements that breach the Code on the internet, on social networks and on television. Emerging challenges related to the use of electronic means to market BMS may call for new strategies for monitoring and enforcing the Code through local regulations.

Conclusión: Se observaron importantes retos de implementación y contextuales para la implementación efectiva de la intervención de actividad física en los servicios de salud.
Objetivo: Avaliar os processos de uma intervenção de atividade física durante a gravidez e o pós-parto. Métodos: No contexto de um programa social de combate à pobreza extrema, as beneficiárias (n=927) receberam uma intervenção que consistia na promoção da prática de atividade física por meio de aconselhamento, oficinas e materiais educacionais. Em 2008-9, 2010 e 2012, foram visitadas unidades de saúde urbanas e rurais, selecionadas aleatoriamente, de quatro entidades federais do México. As informações do processo foram coletadas por prestadores de serviços de saúde, durante observação de consultas e através da aplicação de questionários às beneficiárias. Foram estudados quatro indicadores de implementação da intervenção: fidelidade às atividades planejadas, dose entregue à população, escopo da população-alvo, e acolhimento da intervenção por gestantes e puérperas. Resultados: As unidades de saúde foram visitadas nas etapas inicial (n = 91), intermediária (n = 47) e final (n = 82) do estudo. A dose liberada mostrou um nível de implementação de 81-86%. A fidelidade apresentou <50% de implementação e melhorias significativas foram observadas na maioria dos aspectos avaliados entre as diferentes etapas do estudo, como treinamento de prestadores de serviços de saúde, fornecimento de materiais, aconselhamento e realização de oficinas nas unidades de saúde. Conclusão: Importantes implementações e desafios contextuais foram observados para a efetiva implementação da intervenção de atividade física para beneficiárias dos serviços de saúde investigados.
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 had <50% implementation and significant improvements were observed in most analyzed aspects between the different stages of the study, such as training of health service providers, the supply of materials, counseling, and workshops in health units. Conclusion: Important Implementation and contextual challenges were observed for the effective fulfillment of the intervention of physical activity into primary healthcare services.

BACKGROUND: The Integrated Strategy for Attention to Nutrition (EsIAN in Spanish) is a national strategy within Mexico's conditional cash transfer program (initially Progresa, then Oportunidades, then Prospera, CCT-POP) designed to strengthen the health and nutrition component, address the nutrition transition, and improve the health and nutritional status of its beneficiaries, through 3 main components: 1) procurement of functioning equipment to primary health care (PHC) units; 2) providing free micronutrient supplements to beneficiary women and children; 3) implementing a behavior change communication (BCC) strategy and a training system for PHC providers (PHCPs). OBJECTIVE: We aim to describe the iterative process and evidence-based approach used to design and roll-out the EsIAN at scale, by focusing on the BCC component. METHODS: The BCC strategy was developed by following an iterative process through the following phases: situational analysis, formative research and design of the BCC strategy (using the socioecological framework and the social marketing approach), large-scale feasibility study, redesign, and national scale-up. RESULTS: The review and formative research revealed several barriers and issues that limited program coverage, utilization, and acceptance. These included misconceptions about pregnancy and infant feeding, nonalignment of practices with international recommendations, and lack of knowledge on nutrition and related topics, among others. These results were used to identify priority behaviors and elaborate key messages for mothers/caregivers and providers to develop the BCC strategy. The feasibility study resulted in significant improvements in PHCPs' knowledge, counseling (breastfeeding, and supplement use and consumption), and caregivers' complementary feeding behaviors, and highlighted several design and delivery aspects that needed strengthening. Based on these findings, the BCC strategy was adapted prior to a national scale-up. CONCLUSIONS: The theory-based iterative approach resulted in the identification of specific actions to target, and approaches to do so, as part of the design and roll-out of the BCC strategy at scale.

This study estimated the prevalence of violations of the International Code of Marketing of Breast-milk Substitutes (BMS) and subsequent resolutions of the World Health Assembly (Code) at health facilities, points of sale (POS), and on BMS labelling and media in Mexico. We carried out a cross-sectional survey among 693 mothers with children aged less than 24 months and 48 health providers at public and private health facilities in two states of Mexico. Observational assessment at 20 POS and the health facilities was conducted as well as an analysis of labels on BMS products for sale. Women attending public and private health facilities reported receiving free BMS samples in the previous 6 months (11.1%), and about 80% reported seeing BMS promotion in the mass media. Health providers reported contact with BMS manufacturer representatives in the previous 6 months (15.5%), and only 41.6% of the health providers had knowledge of the Code. BMS promotions were identified at nearly all POS. Analysis of 190 BMS labels showed that 30% included pictures/text idealizing the use of BMS, and all labels incorporated health and nutrition claims. Violations of the Code are prevalent within the health services, POS, and labelling of BMS products. The high percentage of health providers with no knowledge of the Code calls for action at national level to better disseminate and comply with the Code. A transparent, free from commercial influence, and continual monitoring system for Code compliance is needed, including a follow-up component on sanctions for contraventions of the Code.

Resumen: Objetivo: Describir la cobertura y focalización de los Programas de Ayuda Alimentaria (PAA) en México. Material y métodos: Se obtuvo información de 9137 hogares de la Encuesta Nacional de Salud y Nutrición Medio Camino (Ensanut MC) 2016 sobre los PAA que reciben. Se analizó la distribución de los PAA por lugar de residencia, índice de nivel socioeconómico y pertinencia los PAA. Resultados: El 44% de los hogares recibe algún PAA, con mayor concentración en hogares indígenas (70%), de muy bajo nivel socioeconómico (70%) y en inseguridad alimentaria moderada y severa. Los PAA con mayor cobertura fueron Prospera (21%), Liconsa (9%), Programa de Desayunos Escolares (17%) y el Programa de Adultos Mayores; de éstos, el programa mejor focalizado fue Prospera. Conclusiones: Es necesario revisar los recursos de los programas y dirigirlos a la población con mayores carencias y mayor vulnerabilidad nutricional.
Abstract: Objective: To describe the coverage and targeting of Social Food Assistance Programs (SFAP) in Mexico. Materials and methods: Data were obtained from 9137 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.

OBJECTIVE: To explore perceptions of healthcare providers and beneficiaries of Oportunidades program on physical activity during pregnancy and post-partum; and identify current reported practices related to counseling on physical activity in the primary healthcare services in Mexico. MATERIALS AND METHODS: A mixed methods approach was used which is part of a nutrition intervention of the Oportunidades program. Qualitative information was collected through interviews (50=women; 34=providers) and quantitative information was collected by questionnaires (n=88 women; n=64 provider; n=111 observations during consultation). RESULTS: The main barriers were: a) individual (lack of time and social support to childcare); b) sociocultural (gender bias derived from peer groups or family and lack of instructors), and c) environmental (lack of safe and adequate physical places). Only 38% of beneficiary women reported having been counseled on physical activity vs 63.4% of providers who reported having counseled on physical activity (p=0.002). CONCLUSION: There is a need to train healthcare providers and to promote physical activity during pregnancy and post-partum for reducing associated biases.
