Background: Rates of exclusive breastfeeding fall below recommended levels, particularly among women in paid employment. In Mexico, more than half of women are in informal employment, meaning they lack many of the protections that may support breastfeeding. Methods: In-depth interviews with 15 key informants representing government agencies (n = 6 organizations), NGOs (n = 4), international organizations (n = 2), and academia (n = 2) in Mexico. Interviews were conducted between March and June 2023. To understand and describe barriers to breastfeeding among informally employed women in Mexico according to key informants and the current and potential policies to address these barriers, we conducted a qualitative thematic analysis. Results: Current policies to promote, protect, and support breastfeeding predominantly apply to all employed women, but respondents expressed concern that they did not provide adequate protection for women in informal employment. Additional themes concerned the need for relevant programs to be institutionalized and coordinated, discussions of breastfeeding as a right, and the legal equivalence (whether true in practice or not) of formal and informal workers. Conclusions: Women employed in Mexico's informal sector face a dearth of maternity protections. According to key informants, few policies exist to promote, protect, and support breastfeeding among employed women, in general, but the economic vulnerability and challenging working conditions of women in informal employment exacerbates their situation. The lack of access to formal labor protections, such as paid maternity leave, creates a significant barrier to breastfeeding for women in the informal sector. Recommendations include short-term policies to fill gaps in social protection for informally employed women, as well as longer-term solutions such as the development of universal social protection programs and supporting formalization.

In May 2012, the 65th World Health Assembly (WHA) approved six global nutrition targets by 2025 aimed to reduce stunting in children under five by 40%, maintain childhood wasting below 5%, halt obesity, cut anemia in women by 50%, lower low birth weight prevalence by 30%, and increase exclusive breastfeeding (EBF) within the first 6 months to 50%. These targets were extended to 2030, with all of them remaining as originally planned, but the EBF one (increased to 70%), wasting and overweight (both objectives set to eliminate them to negligible concern). Mexico is projected to achieve only one of the six nutrition targets (wasting) by 2025, falling far short of the stunting, low birth weight, anemia, and exclusive breastfeeding for the updated goals by 2030. This letter to the editor describes the most recent prevalence of malnutrition among mothers and children in Mexico. It discusses the challenges pregnant women and children under five years of age face exercising their right to good food, nutrition, and development. The authors reflect on the urgent need to make structural changes to achieve the global nutrition targets by 2030, highlighting the paramount importance of addressing the profound structural obstacles in Mexico and how Mexico's government must prioritize poverty reduction, reduce the marked inequalities, enhance the quality of nutritional care and healthcare infrastructure, and implement climate-resilient agricultural practices to address this pressing issue.

Scaling up effective interventions, policies and programmes can improve breastfeeding (BF) outcomes. Furthermore, considerable interest exists in learning from relatively recent successful efforts that can inform further scaling up, with appropriate adaptations, across countries. The purpose of this four‐country case studies analysis was to examine why and how improvements in BF practices occurred across four contrasting countries; Burkina Faso, the Philippines, Mexico and the United States of America. Literature reviews and key informant interviews were conducted to document BF trends over time, in addition to why and how BF protection, promotion and support policies and programmes were implemented at a national level. A qualitative thematic analysis was conducted. The 'Breastfeeding Gear Model' and RE‐AIM (Reach; Effectiveness; Adoption; Implementation; and Maintenance) frameworks were used to understand and map the factors facilitating or hindering the scale up of the national programmes and corresponding improvements in BF practices. Each of the studied countries had different processes and timing to implement and scale up programmes to promote, protect and support breastfeeding. However, in all four countries, evidence‐based advocacy, multisectoral political will, financing, research and evaluation, and coordination were key to fostering an enabling environment for BF. Furthermore, in all countries, lack of adequate maternity protection and the aggressive marketing of the breast‐milk substitutes industry remains a strong source of negative feedback loops that are undermining investments in BF programmes. Country‐specific best practices included innovative legislative measures (Philippines), monitoring and evaluation systems (United States of America), engagement of civil society (Mexico) and behavior change communication BF promotion (Burkina Faso) initiatives. There is an urgent need to improve maternity protection and to strongly enforce the WHO Code of Marketing of Breast‐Milk Substitutes. Key messages: The effective scale up of national breastfeeding (BF) policies and programs has been identified as a global health priority.There is a need to systematically conduct and compare case studies to understand drivers for the successful dissemination and scale up of national breastfeeding policies and programmes.Implementation science frameworks were key to systematically identify key drivers for the scale up of BF protection, promotion, and support policies and programmes in Burkina Faso, Mexico, the Philippines and the United States.Advocacy, multisectoral political will, financing, monitoring and evaluation, and coordination were key for enabling the BF environments.In all countries, there was a strong need to improve maternity protection and to tighten regulation and enforcement of the WHO Code of Marketing of Breast‐Milk Substitutes.

Milk formula sales have grown globally, particularly through follow‐up formulas (FUF) and growing‐up milks (GUM). Marketing strategies and weak regulatory and institutional arrangements are important contributors to caregivers' decisions about child feeding choices. This study describes maternal awareness, beliefs, and normative referents of FUFs and GUMs among Mexican pregnant women and mothers of children 0–18 months (n = 1044) through the lens of the theory of reasoned action (TRA). A cross‐sectional survey was undertaken in two large metropolitan areas of Mexico. Descriptive analyses were conducted following the constructs of the TRA. One‐third of the participants had heard about FUFs, mainly through health professionals (51.1%) and family (22.2%). Once they had heard about FUFs, the majority (80%) believed older infants needed this product due to its benefits (hunger satisfaction, brain development, and allergy management). One quarter of the participants were already using or intended to use FUFs; the majority had received this recommendation from doctors (74.6%) and mothers/mothers‐in‐law (25%). Similarly, 19% of the women had heard about GUMs. The pattern for the rest of TRA constructs for GUMs was similar to FUFs. Mexican women are exposed to FUFs and GUMs, once women know about them, the majority believe older infant and young children need these products, stating perceived benefits that match the poorly substantiated marketing claims of breast‐milk substitutes. Health professionals, particularly doctors, act as marketing channels for FUFs and GUMs. Marketing of FUFs and GUMs represents a threat to breastfeeding in Mexico and a more protective regulatory and institutional environment is needed. Key messages: Mexican pregnant women and mothers are highly exposed to FUFs and GUMs.Most women who know FUFs and GUMs believe older infants and young children need these products.The perceived benefits of FUFs and GUMs match those displayed in BMS marketing.Health providers are being used as marketing channels for FUFs and GUMs.Stronger regulatory and institutional frameworks for BMS are urgently needed in Mexico.

Background: Aggressive and unregulated marketing of breastmilk substitutes (BMS) results in increased child morbidity and mortality. Unregulated BMS marketing is a major public health concern because it encourages formula consumption at the expense of breastfeeding. This study aimed to identify the sources and characterize the nature of exposure to marketing of BMS among Mexican mothers of children under 18 months of age. As a secondary objective we explored potential association between exposure to BMS marketing and infant feeding practices. Methods: Cross-sectional study, comprising a pre-piloted survey, was conducted between February 2020 to February 2021 with Mexican mothers of children under 18 months of age (n = 754), in two major cities in Mexico. Mothers were selected according to their current infant feeding practices (Breastfeeding only vs. Mixed feeding). We characterized the different BMS marketing sources and scope, and related them with infant feeding practices. In addition, we used logistic regression models to estimate the odds ratio for infant feeding practices by BMS marketing exposure or recommendation. Results: Mothers reported different sources of exposure to BMS promotion, including BMS advertisements in diverse media channels (41.6%), recommendation by a healthcare professional and/or relative (76.2%), and receiving a BMS sample at a hospital (18.6%). By contrast, only 36.5% recalled hearing or seeing breastfeeding information the previous year. The odds of mixed feeding were substantially higher, compared to breastfeeding, when mothers were recommended to use a BMS by doctors/pediatricians (OR: 3.96, 95% CI: 2.00, 7.83). Having seen or heard breastfeeding information in the previous year was associated with a lower risk of mixed feeding compared to breastfeeding only (OR: 0.59, 95% CI: 0.35, 0.99). Conclusions: Mexican mothers of young children in the metropolitan areas studied were highly exposed to BMS marketing and through different mass media channels and inter-personal sources. Health care professionals, particularly doctors/pediatricians, are a source of BMS promotion that are likely to have a strong influence on maternal decisions about infant feeding practices. There is an urgent need to protect mothers and their families against unregulated BMS promotion through mass media channels and directly by influential individuals, including health care providers.

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. [ABSTRACT FROM AUTHOR]

According to the WHO, low birth weight (LBW) affects 15–20% of newborns worldwide. In Mexico, there are no national, state, nor municipal estimates that inform the country's situation over time. The purpose of this study was to estimate the incidence of LBW at the national, state, and municipal levels from 2008 to 2017, and to estimate the LBW incidence based on maternal sociodemographic characteristics, prenatal care and marginalization indexes at the national level using open national data. We used spatial data analysis to georeferenced LBW incidence at the three levels of geographical disaggregation studied. At the national level, the incidence of LBW increased progressively from 6.2% (2008) to 7.1% (2017), and the country's capital represented the area with the highest incidence. Southeastern and central states reported the highest LBW regional incidence. At the municipal level, the number of municipalities with an incidence of LBW ≥8% increased in both male and female newborns. The incidence of LBW was higher as the marginalization indexes increases. The results from this study may assist in the identification of vulnerable groups and the development of public health programs and policies with an intersectoral approach that improves maternal and child nutrition.

Background: High intake of sugar-sweetened beverages (SSB) is linked to increased weight, energy intake, and diabetes. Even though the increasing interest on beverages and water intake, there are few dietary tools carefully validated. The purpose of this paper is to compare a fluid intake 7-day diary against a 24-h recall questionnaire to estimate the fluid consumption in overweight and obese women participating in a randomized controlled trial in Mexico.Methods: This cross-sectional study explored the correlation of reported fluid consumption between two methods: 3-day 24-hr recalls and 7-day diary beverage registry in overweight and obese Mexican women aged 18-45 y (n = 190).Results: There was no difference on median estimated volume (mL/d), nor the median estimated energy (kcal/d) from total beverage consumption registered by the two dietary tools. The crude and rank correlation among the two dietary instruments was high for total fluid consumption in mL/d r = 0.7, p < 0.001 (crude and rank correlation) and for fluid consumption measured as energy intake: r = 0.7; p < 0.001 crude, and r = 0.5; p < 0.001 rank correlation. By type of beverage, the more meaningful rank correlations were for fluid intake in: mL/d, water, alcohol beverages, and SSB; and in kcal/d, alcohol beverages and SSBs (rank correlation ≥ 0.6).Conclusions: Overall, the 7-day diary showed high and strong rank correlations with that reported in the 24-h recall, suggesting that the diary method is a valid dietary tool to evaluate total fluid, water and SSB intake in this population.

Background/Aims: Intense marketing for sugar-sweetened beverages (SSB) along with the human innate preference for sweet taste contributes to the increase in consumption of SSB. It is important to understand the intricacies of dietary intake and global changes to the food supply to understand the complexities facing any intervention promoting water intake. We describe challenges to promote and achieve an increase in water intake and present key findings from a clinical trial examining the effects of substituting water for SSB on triglyceride levels, weight and other cardiometabolic factors in overweight/obese Mexican women. Methods: A randomized trial was conducted in Cuernavaca, Mexico selecting overweight/obese (BMI ≥25 and <39 kg/m2) women (18-45 years old), reporting an intake of SSB of at least 250 kcal/day. Women were randomly allocated to the water and education provision (WEP) group (n = 120) or to the education provision (EP) group (n = 120). Repeated 24 h dietary recall questionnaires, anthropometry, and fasting blood levels were collected at baseline and 3, 6, and 9 months following the intervention. Results: There was no effect of the intervention on triglyceride concentration or on any of the studied outcomes. Post-hoc analyses according to weight at baseline show that triglyceride concentration decreased in obese women. Prevalence of metabolic syndrome after the intervention was lower in obese women from the WEP group. Conclusion: Water intake was increased but insufficient to achieve complete substitution of SSB, without effects on triglyceride concentration. Post-hoc analyses suggested that interventions lowered triglyceride concentration. Further studies are needed. © 2015 S. Karger AG, Basel [ABSTRACT FROM AUTHOR]

In Mexico, the school environment has been promoting sale of unhealthy foods. There is little empirical evidence on multi-stakeholder perspectives around national school food policy to regulate this. We studied stakeholders’ perspectives on the proposed regulation for school sale of unhealthy foods. Comments about the regulation were available from an open consultation process held in June 2010 before the approval and implementation of the regulation. To examine perspectives, we coded 597 comments for beliefs, expectations and demands in NVivo. We created matrices by actors: academics, parents, citizens, health professionals and food industry. For academics, citizens and health professionals, the primary issue regarding the regulation was obesity, while for parents it was health of children. Academics, citizens, health professionals and parents believed that government was responsible for health of citizens, expected that this regulation would improve eating habits and health (i.e. less obesity and chronic diseases), and demanded that unhealthy foods be removed from schools. Parents demanded immediate action for school food policy that would protect their children. Citizens and health professionals demanded nutrition education and healthy food environment. Food industry opposed the regulation because it would not solve obesity or improve diet and physical activity behaviours. Instead, industry would lose income and jobs. Food industry demanded policy aimed at families that included nutrition education and physical activity. There was substantial consensus in narratives and perspectives for most actor types, with the primary narrative being the food environment followed by shared responsibility. Food industry rejected both these narratives, espousing instead the narrative of personal responsibility. Consensus among most actor groups supports the potential success of implementation of the regulation in Mexican schools. With regard to addressing childhood obesity, sound government policy is needed to balance different perspectives and desired outcomes among societal actors, particularly in Mexico between food industry and other actors.

Objective. To describe the design, methods, and challenges encountered during a randomized clinical trial aimed to promote water intake for reducing risks of metabolic syndrome in Mexican women. Materials and methods. In a randomized clinical trial in Cuernavaca, Mexico, overweight and obese (body mass index [BMI] = 25 < 39) women, 18 - < 45 years old with an intake of sugar-sweetened beverages = 250 kilocalories per day (kcal/day) were randomly allocated to the water and education provision group (n = 120) or the education provision only group (n = 120). Results. We screened 1 756 women. The main difficulties encountered were identifying participants with the recruitment criteria, delivering water to participants, and the time demanded from the study participants. Conclusions. The trial's main challenges were difficulties surrounding recruitment, delivery of the intervention, and the time demanded from the study participants. Modifications were effectively implemented without jeopardizing the original protocol. [ABSTRACT FROM AUTHOR]

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.

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.

Objective: to estimate energy, nutrient intake and diet adequacy in preschool-aged children based on data from the Mexican National Health and Nutrition Survey 2012.Material and Methods: dietary data in children < 5 years (n = 1,212) collected through a Semi-quantitative Food Frequency Questionnaire (SFFQ) were analyzed. Energy and daily nutrient intakes and adequacies were calculated comparing by sociodemographic characteristics.Results: median daily energy intake was 1,252 kcal (adequacy 104%). Adequacies above 100% were observed for calcium, zinc, vitamin C, folate, vitamin B12, vitamin A and median of saturated fat. Low percent adequacies were observed for fiber, iron, polyunsaturated fat and vitamin D. Intakes were lower in the southern region compared to other regions. Most intakes and adequacies were higher in urban compared to rural areas, but fiber had the opposite trend. Indigenous children had low intakes and percent adequacies.Conclusions: risks of dietary deficiencies and excess are present in Mexican preschool-aged children, with marked differences across sociodemographicstrata.

Background: There is a limited understanding of the dynamic influences that shape infant and young child feeding (IYCF) decisions over time. We conducted an innovative qualitative study to reconstruct IYCF trajectories across early life course phases, in the context of the socioecological model (SEM) and the commercial determinants of IYCF., Methods: Women of different socioeconomic status were interviewed in two large metropolitan areas in Mexico. Our specific goal was to allow us to better understand if and how the commercial milk formula (CMF) marketing influenced breastfeeding decisions in a complex dynamic way involving the individual, relational, community and societal levels., Results: Hospitals, health professionals, and interactions with social media were key category entry points throughout the prenatal, perinatal, early infancy period and beyond. The CMF industry interfered by engaging a wide array of actors across the different layers of the SEM, most prominently the health care system and the workplace. Through its marketing strategies the CMF operates subconsciously and its messages are most effective when health institutions, health care providers, workplace spaces and social norms are weak in their support for breastfeeding., Conclusions: The cases in our study highlight how, together with a weak breastfeeding counseling system, and health professionals who lack training in breastfeeding and normal infant behavior, lead to the opportunity for CMF marketing to shape infant feeding, and ultimately to the decision to feed formulas that some mothers were not planning to use and cannot afford., (© 2024.

Introduction: Breastfeeding (BF) is considered an essential component of optimal care for child health and development. In the past two decades, global data have shown improvements in some, but not all, BF indicators. Despite these positive changes sales and per capita intake of commercial milk formula (CMF) have increased globally. The CMF industry invests millions of dollars in marketing, which targets families and healthcare professionals (HCP). In Mexico, more than half of the mothers (53%) who feed their infants with CMF chose their Brand on the recommendation of HCP. Understanding the reasons behind the current recommendations for the use of CMF by HCP is important for the design of BF interventions. The primary objective of this study was to explore Mexican HCP' beliefs, attitudes, perceptions, and practices about early infant feeding practices, and reasons for recommending CMF. The secondary objective was to explore pregnant women and mother's perceptions of the infant feeding recommendations they received from HCP, and of the factors that influenced their infant feeding decisions., Methods: The study was based on a secondary qualitative data analysis of a WHO/UNICEF multi-country study. We analyzed focus group discussions (FGDs) and in-depth interviews (IDIs) from Mexico. Data were collected through convenience sampling in Mexico City and Guadalajara. HCP (n = 34) analysis was based on IDIs, and pregnant women or mothers of children 0-18 months ( n = 74) on FGDs and IDIs., Results: Through a thematic analysis, we identified the socioecology of BF and triangulated HCP and women's accounts. HCP, pregnant women, and mothers recognized that several factors might have influenced their infant feeding decisions including healthcare facilities' policies and maternal work conditions. Although HCP believed that BF is the best way to feed newborns and young children, they routinely recommended CMF. On the other hand, pregnant women and mothers had a strong belief that BF is the best way to feed their babies. However, when women sought support from HCP, the latter often recommended switching to CMF., Discussion: This study highlights the discordance between HCP perceptions and mothers' experiences of HCP recommendations about infant feeding. Our findings support a national call for policy actions., Competing Interests: Some HCP reported that they have not had contact with representatives of CMF, but mainly because it is not allowed by the rules of their Institutions, especially those working in public healthcare facilities. However, despite these regulations some HCP were approached by CMF companies and received funding to attend scientific conferences. Among the different types of HCP participating in this study, pediatricians were approached the most by CMF companies. “.. Yes, they [company representatives] live at the pediatrician's, they're there every day…” (In-Depth-Interview- Obstetrician/Gynecologist, Private health care facility).“... Yes, they give us samples, but only for their specialized formulas. Like I mentioned, they don't leave samples for stages 1 and 2. It's just for their specialized formulas. And sometimes they'll give us pens, or towels, small things [...] Yes, yes. They do invite us [to scientific conferences] [...] Well, yes, for example, there's one they organize themselves, a “summit,” that's what they call it, so it's the company's “summit” and they give us conferences on breast milk, on protein allergies, lactose intolerance... These are scientific topics. They pay for the lodging and travel expenses, and we go to the conference [...] Yes, yes [attendance to the conference]...” (In-Depth-Interview- Pediatrician, Private health care facility).HCP participating in the study did not identify receiving funds or gifts from CMF companies as a conflict of interest. Therefore, they did not avoid relationships with the companies in their practice or in their research. “... Well, sponsorship is good, having investigation [research] resources is always good, as long as they have ethical guidelines [...] That the research is based on the truth…“ (In-Depth-Interview- Pediatrician, public health care facility).The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Hernández-Cordero, Vilar-Compte, Tomori, Lara-Mejía, Rovelo-Velázquez, Hayes and Pérez-Escamilla.)

Introduction: While breastfeeding is recognized as providing optimal nutrition for infants and toddlers, maternal employment is a commonly mentioned barrier to breastfeeding. The goal was to (a) identify key actors participating in the design and implementation of workplace breastfeeding interventions in Mexico, (b) understand the complexity of interactions between the actors, and (c) map the connections and influence between the actors when looking into networks of Advice, Command, Funding, and Information., Method: Following the NetMap methodology, a total of 11 semi-structured interviews with 12 interview partners from 10 organizations were conducted. Interview data were analyzed, and networks were analyzed and visualized, using a social network mapping software., Results: A total of 83 actors from five different actor groups were identified. Four networks were constructed along the four types of connections: Advice, Command, Funding, and Information. The actors were connected by 580 connections with 446 unique links. Based on various network statistics, the Mexican Institute of Social Security, the Mexican Secretary of Labor and Social Welfare, UNICEF, and the Mexican Secretary of Health were identified to be key actors., Conclusion: To increase the likelihood of success of workplace breastfeeding interventions, the role of the actors "Employers" and "Women" needs to expand. They should be actively involved in the decision-making process, together with the identified key actors. It is further recommended to re-introduce a national breastfeeding strategy for Mexico that includes policies for workplace breastfeeding interventions., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationship that could be construed as a potential conflict of interest., (Copyright © 2023 Litwan, Lara-Mejía, Chahine, Hernández-Cordero, Vilar-Compte and Pérez-Escamilla.)

Return to work is one of the most significant barriers to breastfeeding (BF). Family-friendly policies are critical to ensure that BF and maternal work are not mutually exclusive. This study aims to determine contextual factors and underlying mechanisms influencing the implementation of workplace policies in Mexico. Following a qualitative approach, the study was conducted in the following four cities in Mexico: Mérida, Chihuahua, Guadalajara, and Monterrey. Interviews were conducted in 14 workplaces, and included 49 (potential) beneficiaries, 41 male employees, and 21 managers and human resources personnel. The information collected was analyzed through a deductive thematic analysis and mapped against the Context-Mechanism-Outcome framework of Breastfeeding Interventions at the Workplace. Contextual factors influencing a BF-friendly environment in the workplace were as follows: work-schedule flexibility, provision of lactation services (i.e., BF counseling) other than a lactation room, women's previous experience with BF and family-friendly environments in the workplace. The underlying mechanisms enabling/impeding a BF-friendly environment at the workplace were as follows: awareness of Mexican maternity protection legislation, usage of BF interventions in the workplace, culture, supervisor/co-worker support and BF-friendly physical space. To achieve a BF-friendly environment in the workplace, actions at the level of public policy and workplaces must accompany adherence to Mexican legislation.

Mexico is facing the double burden of malnutrition, and adolescents are not an exception. Diet plays an important role, both in causing overweight and undernutrition. This study aimed to describe the dietary patterns (DPs) of Mexican adolescents and to examine its association with nutritional status using data from adolescents aged 12-19 years ( n = 7380) from the National Survey of Health and Nutrition (ENSANUT-2006). Principal component analysis was used to derivate the DPs. Associations between DP and nutritional status were determined by prevalence ratio (PR). Four DPs were identified: nontraditional and breakfast-type, Western, plant-based, and protein-rich. The prevalence of overweight and obesity was higher in adolescents who scored high on the Western pattern (PR: 1.15, 95% CI: 1.08-1.21) or on the plant-based pattern (PR: 1.09, 95% CI: 1.03-1.17). The Western pattern was positively associated with anemia in girls (PR: 1.18, 95% CI: 1.03-1.35), while the nontraditional and breakfast-type pattern was inversely associated with anemia in adolescents aged 12-15 years (PR: 0.87, 95% CI: 0.76-0.99) and in girls (PR: 0.84, 95% CI: 0.75-0.97). The Western and plant-based patterns were simultaneously associated with overweight-obesity and at least one indicator of undernutrition. In the context of the double burden of malnutrition, dietary advice must consider malnutrition in all its forms.

Objective: To document the changes in BMI and the prevalence of overweight and obesity in young women living in poverty in a semi-urban community in Mexico., Methods and Procedures: Women who had previously participated in a longitudinal research study (1997-2000) were re-assessed in 2005. Anthropometric measurements were obtained using standard procedures, and socio-demographic questionnaires were administered. Total and annual rate of change in BMI and change in the prevalence of overweight and obesity (BMI > or = 25.0 and > or =30.0) were estimated., Results: Mean age in 2005 was 30.0 +/- 5.7 years (n = 683) and time between recruitment and follow-up was 6.4 +/- 1.0 years. Mean change in BMI was +3.6 +/- 2.7 (range -8.2 to +14.6). In 2005, 500 (73.2%) women were overweight, up from 263 (38.5%) in the original assessment. The prevalence of obesity tripled over the follow-up period (from 9.8% to 30.3%). The mean annual rate of change in BMI was +0.6 (+/-0.4). After adjustment for age and parity at baseline, an annual rate of change of BMI above the sample median (>0.5) was associated with lower levels of formal education., Discussion: The annual increase in the prevalence of overweight and obesity in this sample is double that which was reported at a national level in Mexico. An understanding of the determinants of this rapid increase among the women living in poverty in Mexico is urgently needed.
