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.

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.

Background: Breastfeeding can be affected by maternal employment. This is important considering that in 2019, 47.1% of women globally participated in the labor force. The aim of this study was to review workplace interventions to promote, protect and support breastfeeding practices among working mothers globally. Methods: A systematic review was conducted following the guidance of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Observational, experimental and qualitative peer-reviewed studies in English and Spanish, published between 2008 and 2019 were included. The review focused on working women who were pregnant, breastfeeding or who recently had a child, and women's working environments. The outcomes of interest included breastfeeding intentions, initiation, exclusivity and duration, confidence in breastfeeding or breastmilk extraction, and perceived support at workplace. Quality was assessed according to National Institute for Health and Care Excellence (NICE) checklist for systematic reviews. It was registered on PROSPERO (#140624). Results: Data was extracted from 28 quantitative and 9 qualitative studies. The most common interventions were designated spaces for breastfeeding or breastmilk extraction (n = 24), and the support from co-workers (n = 20). The least common interventions were providing breast pumps (n = 4) and giving mothers the flexibility to work from home (n = 3). Studies explored how interventions affected different breastfeeding outcomes including breastfeeding duration, breastfeeding exclusivity, confidence in breastmilk expression, and breastfeeding support. The evidence suggests that workplace interventions help increase the duration of breastfeeding and prevent early introduction of breastmilk substitutes. Having a lactation space, breastmilk extraction breaks, and organizational policies are key strategies. However, to achieve equitable working conditions for breastfeeding mothers, organizational and interpersonal changes need to occur as well. Conclusions: The systematic review revealed that interventions at the workplace are important in protecting, promoting and supporting breastfeeding among working mothers. To achieve equitable work environments and fair nutritional opportunities for infants of working mothers, interventions should focus at the three ecological layers – individual, interpersonal, and organizational. The quality of studies can be improved. There is a need for studies assessing impacts of workplace interventions on infant feeding practices, mothers' self-esteem and outcomes such productivity and abstentionism. [ABSTRACT FROM AUTHOR]

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: Woman's weight changes during pregnancy and postpartum contribute to obesity and health outcomes later in life. This study aimed to identify and characterize weight change trajectories from pregnancy to one year postpartum among adult women.Methods: We used data from an ongoing cohort of healthy adult women (n = 819) with singleton pregnancies from 2007 - 2011. Sociodemographic data, pre-pregnancy body weight, and sedentary and breastfeeding practices were collected using questionaries applied by trained professionals. We applied a group-based trajectory modeling to distinguish weight change measured in the second and third trimesters of pregnancy and at one month, six, and 12 months postpartum. Multinomial regression models were run to characterize each trajectory.Results: We identified six weight change trajectories with the main difference in the patterns followed after one month of delivery. One in three women (36.7%) was classified in some of the three postpartum weight gain trajectories and regained weight from the second trimester of the first year postpartum. Women who followed some of these trajectories were more likely to have higher age, obesity before pregnancy, < 10 years of schooling, and partner, compared with women (10.7%, n = 87) in a postpartum sustained-fast-lost-weight trajectory (p < 0.05).Conclusions: Women with obesity before pregnancy have higher odds of regaining gestational weight after delivery without reaching their pre-pregnancy weight. The first six months postpartum are crucial to establishing obesity prevention strategies. Further research is needed to evaluate the effect of the interventions that prevent substantial weight gain through reproductive years in high-risk women. [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.
