Madres del mar: maternar y cuidar en las caletas pesqueras
(Revista Punto Género, 2025-12) Undurraga, Rosario; Basualto, Camilo
Este estudio cualitativo examina las experiencias de maternidad y cuidado de mujeres trabajadoras en caletas pesqueras artesanales del litoral central chileno. A partir de 11 entrevistas, se analizan las estrategias que estas mujeres despliegan para conciliar mandatos tradicionales de género con el trabajo remunerado en espacios laborales masculinizados. Los hallazgos muestran regímenes híbridos de cuidado —familiarista, comunitario-solidario y autonomía precarizada— que surgen ante la precariedad y la crisis sistémica del cuidado, junto con tensiones entre la transmisión de saberes pesqueros y el deseo de movilidad social para sus hijos/as. La doble jornada, la territorialidad costera y la violencia de género configuran trayectorias vitales y maternidades situadas que combinan reproducción y subversión de normas de género y desigualdades sociales. El artículo concluye con un llamado a políticas de corresponsabilidad que reconozcan el trabajo productivo y reproductivo invisibilizado de estas trabajadoras del mar, desnaturalizando el autosacrificio como la única vía para la sostenibilidad vital. This qualitative study examines the experiences of motherhood and caregiving among women working in artisanal fishing coves along the central coast of Chile. Based on 11 interviews, it analyzes the strategies these women deploy to reconcile traditional gender norms with paid work in masculinized workspaces. The findings reveal hybrid care regimes —familiarist, communitybased/solidary, and precarious autonomy— that emerge in response to precarious conditions and the systemic crisis of care, along with tensions between the transmission of fishing knowledge and the aspiration for social mobility for their children. The double burden, coastal territoriality, and gender-based violence shape life trajectories and situated motherhoods that simultaneously reproduce and challenge gender norms and social inequalities. The article concludes with a call for co-responsibility policies that acknowledge the undervalued productive and reproductive labor of these women working in small-scale fisheries, questioning the normalization of self-sacrifice as the only path to sustaining life.

Prevalence and determinants of energy drink consumption among chilean adolescents
(MPDI, 2025-11-05) López-Arana, Sandra; Bustos-Arriagada, Edson
Background: Energy drink (ED) consumption has increased significantly among adolescents worldwide, constituting a high-risk behavior with important public health implications. These beverages are associated with cardiovascular disturbances, sleep disorders, anxiety symptoms, and risky behaviors, especially when combined with alcohol. In Chile, monthly per capita ED consumption among individuals aged 14 to 30 increased ninefold between 2010 and 2020. Objectives: To examine the prevalence of ED consumption and its associated determinants among Chilean adolescents enrolled in grade eight through grade twelve. Methods: Data were drawn from the national representative survey 2023 entitled Fifteenth National Study on the School Population of Chile (ENPE). The final sample included 45,042 adolescents. Besides descriptive analyses, both bivariate and multivariate logistic regression models were used to examine associations between sociodemographic characteristics, parental presence, monitoring, and ED consumption outcomes. Results: Lifetime prevalence of ED consumption was 71.0%, with higher rates in females (72.8%) than males (69.4%). Past-month consumption was reported by 46.2%, with a higher prevalence in males (48.3%) than females (43.9%). Lifetime consumption of ED mixed with alcohol (AmED) was 23.2%, being more frequent among females (26.4%) than males (19.9%). Age, grade level, and indigenous identity were consistently associated with higher odds of consumption. Parental monitoring and involvement indicators were inversely associated with both ED and AmED consumption. Conclusions: This study reveals a high prevalence of ED consumption among Chilean adolescents, with notable gender differences. Family protective factors, particularly parental monitoring and cohesion, emerge as key determinants of this risky behavior and warrant prioritization in public health prevention efforts.

Association Between Exclusive Breastfeeding, Nutritional Status and Eating Behavior, in Chilean Schoolchildren: A Cross-Sectional Study
(MPDI, 2025-10-31) Lasserre-Laso, Nicole; Leiva-Manzor, Guillermo; Bustos-Arriagada, Edson; Etchegaray-Armijo, Karina
Objectives: The aim of this study was to analyze the association between exclusive breastfeeding (EBF) up to six months and both nutritional status and eating behavior in Chilean schoolchildren aged 5 to 8 years. Methods: A cross-sectional study was conducted involving 109 children aged 8–10 years from three cities in Chile. EBF was assessed retrospectively through caregiver questionnaires. Eating behavior was evaluated using the Spanish version of the CEBQ. Anthropometric measurements (weight, height, and waist circumference) were obtained following a standardized protocol to determine nutritional status and waistto-height ratio. Differences between EBF and non-EBF groups were analyzed using the Wilcoxon–Mann–Whitney and Kruskal–Wallis tests. Results: Eating behavior scores for pro-intake (“food approach”) were strongly associated with obesity among non-EBF children (ratio = 1.24, p = 0.001). Children with abdominal obesity who were not EBF showed higher scores for food approach behaviors (ratio = 1.22, p = 0.011). A significant trend was observed in the subscale Enjoyment of Food and Emotional vereating in children with obesity (p = 0.011 and p = 0.008), abdominal obesity (p = 0.031 and p = 0.017), and cardiometabolic risk (p = 0.036 and p = 0.049) in the non-EBF group, compared to those who were EBF up to 6 months of age. Conclusions: Scores reflecting a tendency toward higher food intake were strongly associated with obesity and other obesity-related parameters in children who did not experience EBF during early childhood. Having been exclusively breastfed, regardless of current nutritional status, was associated with lower scores on pro-obesity behaviors.

Biomarkers of oxidative stress in maternal plasma, umbilical cord and placenta of patients with gestational diabetes: a systematic review and meta-analysis
(Elsevier, 2025-05-06) Etchegaray-Armijo, Karina; Bustos-Arriagada, Edson; Navarro-Rosenblatt, Deborah; Vera, Claudio; Garmendia, María Luisa; Sobrevia, Luis; López-Alarcón, Camilo; Casanello, Paola
Objective: To determine the association between Gestational Diabetes Mellitus (GDM) and oxidative stress biomarkers in the mother, placenta, and newborn. Methods: We conducted a systematic review and meta-analysis following the PRISMA guidelines. We searched PubMed/MEDLINE and the Web of Science database without language restrictions. The search was updated on December 28, 2023, and included reports published between 1998 and 2021. Two independent reviewers performed article selection and data extraction. Results: Our findings show a significant increase in malondialdehyde and 8-isoprostane levels in the maternal plasma and placenta of women with GDM compared to those without GDM (SMD [95 % CI] = 1.99 [1.51, 2.48], Tau2 = 1.51, I 2 = 94 %, p < 0.00001; SMD [95 % CI] = 1.90 [0.08, 2.72], Tau2 = 1.14, I 2 = 93 %, p < 0.00001, respectively). Additionally, there was a decrease in superoxide dismutase (SOD) levels in maternal plasma (SMD [95 % CI] = − 2.80 [-5.23, − 0.36], Tau2 = 7.56, I 2 = 98 %, p < 0.00001). However, no significant changes in SOD were observed in the placenta or the umbilical cord blood of offspring from women with GDM (SMD [95 % CI] = − 1.79 [-4.66, 1.07], Tau2 = 6.23, I 2 = 97 %, p < 0.00001; SMD [95 % CI] = − 1.07 [-3.37, 1.24], Tau2 = 5.31, I 2 = 97 %, p < 0.00001, respectively).

Comunicación en canciones inspiradas por noticias: Construyendo memoria de víctimas
(Universidad de Santiago de Chile, 2025-12-31) Figueroa-Bustos, Arturo
Las noticias, desde hace siglos, han motivado la creatividad en los músicos. Sobre la base de las funciones periodísticas de la música, este artículo analiza las formas recursivas en las cuales las noticias pueden inspirar a un grupo de músicos creadores y cómo, a su vez, dichas canciones se convierten en vehículos para comunicar tales noticias. Para ello realiza un análisis cualitativo de entrevistas a compositores chilenos que explican, en un podcast, la creación de 10 canciones inspiradas por noticias. Los hallazgos muestran que, fundamentalmente, las canciones chilenas inspiradas por noticias refieren a personas anónimas a las que les ocurren hechos trágicos y mortales, los que, para los compositores, son historias significativas en términos valóricos que no deben olvidarse. For centuries, the news has inspired musicians' creativity. Based on the journalistic functions of music, this article analyzes the recursive ways in which news can inspire a group of creative musicians and how, in turn, these songs become vehicles for communicating those news pieces. In order to do so, it conducts a qualitative analysis of interviews with Chilean composers who explain, in a podcast, the creation of 10 news-inspired songs. The findings show that, fundamentally, Chilean news-inspired songs refer to anonymous people who experience tragic, life-threatening events, which, for the composers, are significant stories in terms of values that should not be forgotten. Durante séculos, as notícias têm motivado a criatividade dos músicos. Partindo da base das funções jornalísticas da música, este artigo analisa as formas recursivas nas quais as notícias podem inspirar um grupo de músicos criadores e como, ao mesmo tempo, as suas canções se tornam veículos para comunicar essas notícias. Para isso, realiza-se uma análise qualitativa de entrevistas com compositores chilenos que explicam, em um podcast, a criação de 10 canções inspiradas em notícias. Os resultados mostram que, fundamentalmente, as canções chilenas inspiradas em notícias referem-se a pessoas anônimas que vivenciaram eventos trágicos e fatais, que, para os compositores, são histórias significativas em termos de valores que não devem ser esquecidas.
