- Resumen: The association between food access and children's diet quality has been documented mainly from its external dimension (e.g., availability, prices, food properties, and marketing). However, existing research has underscored that the external food environment cannot fully account for variations in children's diet quality, even amid the COVID-19 lockdown. It is increasingly evident that elements within the domestic food environment also play a crucial role in shaping this relationship. Specifically, gender roles influence how food is procured and consumed, along with challenges related to time constraints. This study explores the influence of the domestic time-gender axis and household dynamics in food access and children's dietary quality in 14 female-headed households in Santiago, Chile, during the COVID-19 lockdown. Employing a photo-elicitation exercise, we engaged with families residing in the same urban neighborhood but exhibiting varying levels of dietary quality among their children. Our analysis utilized a framework incorporating both socio-ecological food environment and gender theories. Our findings show that within these households, only one unit of "person-time" was available to address all food and caregiving tasks. Due to an unequal gender system, this limited time allocation was disproportionately absorbed by women, who were already burdened with multiple responsibilities. The lack of time favors the consumption of ultra-processed foods and hinders the intake of fresh foods. Other associated intrahousehold dynamics, such as children's fussiness and special diets, accentuates these time scarcity consequences. These difficulties were further exacerbated by strategies adopted in response to the COVID-19 lockdown, however, in families where food-related responsibilities were shared more equitably the lockdown was less disrupting. These results indicate that on top of external food environment policies, comprehensive gender-transformative policies that include food socialization processes are needed to promote healthier diets among all.

- Resumen: Introduction: Menarche is the last stage of pubertal development, which coincides with the completion of longitudinal growth. As a consequence of the lack of national and up-to-date data related to post-menarcheal (PM) growth, the aim of our work was to evaluate post menarcheal growth in a group of contemporary healthy Chilean girls followed, prospectively, until 4 years post-menarche. Methods: This study was nested within the GOCS cohort, in a prospective fashion. The girls were followed yearly after menarche for at least four years. We modeled each girl growth using a Super Imposition by Translation and Rotation (SITAR) model. Results: A total of 534 girls were evaluated prospectively, 399 girls had height measured two years after menarche, 421 after three years, and 364 of 534 had height measured at four year post menarche. Expected height gained PM, in the complete study group was 6.6 ± 2.5 cm. We observed that the largest gain in height occurred after the first year PM (3.8 1.5 cm). According to the age of menarche, the group with earlier menarche (< 11 years old ) had a greater height gain in cm after four years PM ( 8.2± 3.2 cm ) and the smallest gain was among girls with menarche at an age older than 13 yr (4.4±1.6) ( p<0.001). Age at menarche was significantly associated with all post menarche growth patterns (size, timing and intensity), indicating that girls with older age at menarche grew taller, later and slower than girls with younger age at menarche. Adjusting PM growth pattern by BMI maintained all these association. Applying the SITAR model specifically , girls experiencing menarche after the age of 13 years exhibited slower growth , occurring slightly earlier and with less intensity when adjusted by BMI at menarche . Conclusion: In a national and updated dataset we observed that girls grew until 4 years post menarche an average of 6.6 ± 2.5 cm., with greatest gain occurring in the first year PM , (3.8 ± 1.5 cm). Age at menarche was associated with menarche growth patterns.},

- Resumen: Objective: Sugar-sweetened beverages (SSB) are heavily advertised globally, and SSB consumption is linked to increased health risk. To reduce unhealthy food marketing, Chile implemented a regulation for products classified as high in energies, sugar, saturated fat or sodium, starting with a 2016 ban on child-targeted advertising of these products and adding a 06.00-22.00 daytime advertising ban in 2019. This study assesses changes in television advertising prevalence of ready-to-drink beverages, including and beyond SSB, to analyse how the beverage industry shifted its marketing strategies across Chile's implementation phases.

Design: Beverage advertisements were recorded during two randomly constructed weeks in April-May of 2016 (pre-implementation) through 2019 (daytime ban). Ad products were classified as 'high-in' or 'non-high-in' according to regulation nutrient thresholds. Ads were analysed for their programme placement and marketing content.},

- Resumen: Background: Antenatal micronutrient supplementation has been defined as a priority for Low-and Middle-income Countries (LMICs). However, it is also relevant to assess its performance in middle-high income countries, such as Chile, particularly given the post-pandemic food insecurity context.

Aim: To assess the use (frequency and doses) of daily recommended supplementation (iron (15-30 mg), folic acid (FA) (400-800 μg/day), and vitamin (VD) (400 IU)) in a sample of Chilean pregnant women.

Methods: In 1, 507 pregnant women selected from public health care registries of the Southeast area of Santiago-Chile, we collected maternal, supplement use, sociodemographic, and nutritional information at the first (<15 weeks), second (24-28 weeks), and third trimesters (32-36 weeks) of gestation by using a researcher administer online questionnaire.},

- Resumen: Preventable risk factors are responsible of at least 40% of cases and almost 45% of all cancer deaths worldwide. Cancer is already the leading cause of death in almost half of the Latin American and the Caribbean countries constituting a public health problem. Cost-effective measures to reduce exposures through primary prevention and screening of certain types of cancers are critical in the fight against cancer but need to be tailored to the local needs and scenarios. The Latin America and the Caribbean (LAC) Code Against Cancer, 1st edition, consists of 17 evidence-based recommendations for the general public, based on the most recent solid evidence on lifestyle, environmental, occupational, and infectious risk factors, and medical interventions. Each recommendation is accompanied by recommendations for policymakers to guide governments establishing the infrastructure needed to enable the public adopting the recommendations. The LAC Code Against Cancer has been developed in a collaborative effort by a large number of experts from the region, under the umbrella strategy and authoritative methodology of the World Code Against Cancer Framework. The Code is a structured instrument ideal for cancer prevention and control that aims to raise awareness and educate the public, while building capacity and competencies to policymakers, health professionals, stakeholders, to contribute to reduce the burden of cancer in LAC.},

 - Resumen: Tobacco, secondhand smoke (SHS), and alcohol, all carcinogens, are leading preventable cancer risk factors in Latin America and the Caribbean (LAC). Since 2000, smoking and SHS exposure have significantly decreased in the region. Yet alcohol consumption remains high. The entry of nicotine-related products such as electronic cigarettes (e-cigs) threatens achievements made in tobacco control and chronic diseases prevention, including cancer. E-cigs use is likely associated with smoking initiation among adolescents who had never smoked and dual use with combustible tobacco products. Therefore, the LAC Code Against Cancer recommends to the public actions they can take to reduce their risk of cancer: 1. Don't smoke or use any type of tobacco. If you do, quitting is possible, with professional help if needed. Don't use e-cigarettes either, as they lead to tobacco use. 2. Make your home a smoke-free place. Respect and promote laws that ensure smoke-free spaces to protect our health. and 3. Avoid drinking alcoholic beverages. This helps prevent several types of cancer. The Code recommends to policymakers a package of cost-effective policies based on the MPOWER and SAFER to prevent cancer at the population level. It also recommends that primary care health professionals: 1. Ask all their patients and their families whether they smoke or vape, inform them about the harms of smoking and vaping, and promote tobacco and nicotine related products cessation strategies among users. 2. Inform about the harms of exposure to SHS, especially among children, and promote smoke-free environments, and 3. Prevent alcohol use by their patients and their families, use tools to assess use, intensity, and frequency, and apply brief counseling intervention to support alcohol abstinence in primary care.},

 - Resumen: In Latin America and the Caribbean a considerable proportion of the population have excess body weight, do not meet the recommendations of physical activity and healthy diet, and have suboptimal rates of breastfeeding. Excess body weight is associated with at least 15 cancer sites, physical activity protects against three cancers, with some evidence suggesting a protective effect for eight more cancer sites, and sedentary behavior probably increases the risk of five cancer sites. Fiber and wholegrains protect against colorectal cancer, high intake of fruits and vegetables could reduce the risk of aerodigestive cancers; processed and red meat increase the risk of colorectal cancer; and very hot beverages are associated with esophageal cancer. Moreover, sugar-sweetened beverages and ultra-processed foods are a convincing cause for excess body weight, increasing cancer risk through this pathway, with some emerging evidence suggesting also direct pathways. Breastfeeding protects against breast cancer, and could protect against ovarian cancer. Taking this evidence into account, the Latin America and the Caribbean Code Against Cancer recommends the general public to maintain a healthy body weight, be physically active and limit sedentary behavior, eat a healthy diet (eat plenty of vegetables, fruits, wholegrains and legumes; avoid sugar-sweetened beverages and processed meat; and limit ultra-processed foods, red meat and very hot beverages), and breastfeed. Moreover, the Latin America and the Caribbean Code Against Cancer also includes a set of public policy recommendations for cancer prevention to inform policy makers and civil society about the need of policies to shape healthy environments and create opportunities to facilitate the adoption of the recommendations directed to the public.},

Environment international, 181, 108241. https://doi.org/10.1016/j.envint.2023.108241



 - Resumen: Introduction: High mammographic density is among the strongest and most established predictors for breast cancer risk. Puberty, the period during which breasts undergo exponential mammary growth, is considered one of the critical stages of breast development for environmental exposures. Benzylbutyl phthalate (BBP) and perfluorooctanoic acid (PFOA) are pervasive endocrine disrupting chemicals that may increase hormone-sensitive cancers. Evaluating the potential impact of BBP and PFOA exposure on pubertal breast density is important to our understanding of early-life environmental influences on breast cancer etiology.



Objective: To prospectively assess the effect of biomarker concentrations of monobenzyl phthalate (MBzP) and PFOA at specific pubertal window of susceptibility (WOS) on adolescent breast density.},

 - Resumen: Background: Tools for measuring adherence to sustainable healthy diets among children and adolescents are lacking.



Objective: To advance methods for measuring adherence to sustainable healthy diets among children and adolescents by adapting an existing index, compare scores obtained using the original and adapted versions of the index in a sample of Chilean children, and describe the adapted index association with diet characteristics.



Methods: The Planetary Health Diet Index (PHDI) was adapted to better reflect children's and adolescents' nutritional requirements. The adapted index (PHDI-C) comprises 16 components with a maximum score of 150 points. PHDI-C was piloted among a sample of 958 Chilean children (3-6 years) using dietary data collected in 2016 through single 24-h recalls. A decision tree and food disaggregation methodology were developed to guide the calculation of scores. Scores obtained using the original and adapted versions of the index were compared. Linear regression models adjusted by child's gender and age were fitted to explore associations between total PHDI-C score, dietary recall characteristics and nutritional composition of children's diets.

 - Resumen: Objective: To assess the association between child ultra-processed food (UPF) consumption and home-school learning environment characteristics during school closures due to the COVID-19 pandemic in schoolchildren with low- and middle income in Chile.



Design: Cross-sectional. UPF consumption was collected using the Nova screener. We apply the structured days hypothesis (SDH) to assess home-school learning environment characteristics with three constructs that summarised school preparedness for online teaching and learning, school closure difficulties for caregivers and child routine. We explored associations between child UPF consumption and home-school environment characteristics using multivariate linear regression analyses after controlling for child demographic and school characteristics.

Setting: Low- and middle-income neighbourhoods in southeastern Santiago, Chile.},

 - Resumen: In 2011, Chile added 12 mandatory extra weeks of maternity leave (ML). In January 2015, a pay-for-performance (P4P) strategy was included in the primary healthcare system, incorporating exclusive breastfeeding (EBF) promotion actions. The COVID-19 pandemic led to healthcare access difficulties and augmented household workloads. Our aim was to evaluate the effect of a 24-week ML, the P4P strategy, and COVID-19 on EBF prevalence, at 3 and 6 months in Chile. Aggregated EBF prevalence data from public healthcare users nationwide (80% of the Chilean population) was collected by month. Interrupted time series analyses were used to quantify changes in EBF trends from 2009 to 2020. The heterogeneity of EBF changes was assessed by urban/setting and across geographic settings. We found no effect of ML on EBF; the P4P strategy increased EBF at 3 months by 3.1% and 5.7% at 6 months. COVID-19 reduced EBF at 3 months by - 4.5%. Geographical heterogeneity in the impact of the two policies and COVID-19 on EBF was identified. The null effect of ML on EBF in the public healthcare system could be explained by low access from public healthcare users to ML (20% had access to ML) and by an insufficient ML duration (five and a half months). The negative impact of COVID-19 on EBF should alert policy makers about the crisis's effect on health promotion activities.},

 - Resumen: 

Introduction: This study assesses the impact on prices of the 2016 Chilean comprehensive food policy package, centred around front-of-package warning labels for food and beverages high in saturated fats, sugars, calories and/or salt, on food and beverage prices, labelled or not.

Methods: Data from Kantar WorldPanel Chile, from January 2014 to December 2017, were used. The methodology implemented was interrupted time series analyses with a control group on Laspeyres Price Indices on labelled food and beverage products.

Results: After the regulations were implemented, prices among different categories of products (eg, high-in; reformulated but still high-in; reformulated and not high-in; not high-in) did not change with regulations relative to the control group. Specific price indices (relative to the control group) for households from different socioeconomic strata remained unchanged.

Conclusions: Even where reformulation was extensive, we found no evidence that it was associated with price changes, at least during Chile's first year and a half of regulation implementation.

 - Resumen: Introduction: Food access is associated with dietary quality; however, people living in similar physical environments can have different food access profiles. Domestic environments may also influence how food access relates to dietary quality. We studied food access profiles of 999 low-middle income Chilean families with children during the COVID-19 lockdown and how these profiles relate to dietary quality; secondarily, we also explore the role of the domestic environment in this relationship.},

 - Resumen: As childhood obesity rates continue to rise, health organizations have called for regulations that protect children from exposure to unhealthy food marketing. In this study, we evaluate the impact of child-based versus time-based restrictions of “high-in” food and beverage advertising in Chile, which first restricted the placement of “high-in” advertisements (ads) in television attracting children and the use of child-directed content in high-in ads and, second, banned high-in ads from 6am-10pm. “High-in” refers to products above regulation-defined thresholds in energy, saturated fats, sugars, and/or sodium. High-in advertising prevalence and children’s exposure to high-in advertising are assessed.},
