    Feeding behaviour and lifestyle of children and adolescents one year after lockdown by the COVID-19 pandemic in Chile
    (MDPI, 2021-11) Bustos-Arriagada, Edson; Fuentealba Urra, Sergio; Etchegaray Armijo, Karina; Quintana Aguirre, Nicolás; Castillo-Valenzuela, Oscar
    Lockdown caused by the COVID-19 pandemic may have influenced feeding behaviour and lifestyle in children and adolescents. The purpose of this study was to analyse feeding behaviour and lifestyle in children and adolescents one year after lockdown by the COVID-19 pandemic in Chile. In this cross-sectional study an online survey was implemented in 1083 parents and care- givers regarding their children’s feeding behaviour and lifestyle and sociodemographic background. The results showed that “eat breakfast daily” (89.2%), “not overnight food intake” (69.9%) and “not fast-food intake” (66.0%) were the most frequent reported feeding behaviours, particularly in pre-school children. Respondents declaring healthy feeding behaviours and lifestyle were 23.4 and 23.7%, respectively, with no significant differences by sex. In pre-school children, families with three or fewer members and parents or caregivers with an undergraduate or postgraduate degree reported a significantly better feeding behaviour and lifestyle compared to families with more than three members and parents or caregivers without an undergraduate or postgraduate degree. In conclusion, the pandemic lockdown had a negative impact in lifestyle in children and particularly in adolescents. Healthier feeding behaviour was associated with fewer family members and parents or caregivers with at least an undergraduate degree.

    Nutritional Status of 8,128,014 Chilean and Immigrant Children and Adolescents Evaluated by the National Board of School Aid and Scholarships (JUNAEB) Between 2013 and 2023
    (MDPI, 2025-02-17) Bustos-Arriagada, Edson; Vásquez, Fabián; Etchegaray-Armijo, Karina; López-Arana, Sandra
    Introduction: Nutritional issues, including overweight and obesity, along with the rising number of immigrants facing their own nutritional problems, continue to keep Chile on alert. Objective: To evaluate the epidemiological and nutritional status changes among Chilean and immigrant boys, girls, and adolescents (BGA) in schools evaluated by the National Board of School Aid and Scholarships (JUNAEB) from 2013 to 2023. Methods: This descriptive study analyzed individual, anonymous, and de-identified data on the nutritional status of BGA in pre-kindergarten, kindergarten, first grade, fifth grade, and the first year of high school using the JUNAEB Nutritional Map. Results: The sample consisted of 8,128,014 BGA, 49.2% women and 50.8% men. In 2013, immigrant BGA represented 0.4% of the total number of children evaluated, and by 2023, this percentage increased to 7.9%. It was observed that Chilean BGA had a lower proportion of thinness, risk of thinness, stunting, and normal weight, but a higher proportion of overnutrition compared to immigrants, similar to observations made during the COVID-19 pandemic. Comparisons by sex showed that Chilean and immigrant women had a lower percentage of thinness, risk of thinness, obesity, severe obesity, and stunting, and a higher proportion of normal weight when compared to men. Conclusions: The rise in immigrant BGA within the Chilean school system, together with the nutritional differences between both groups, highlights the need to consider these particularities when designing nutritional public policies in the health and education sectors.

    Prevalence and determinants of energy drink consumption among chilean adolescents
    (MDPI, 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.

    Vitamin D status and obesity in children from Chile
    (Springer Nature, 2021) Pérez-Bravo, Francisco; Duarte, Lissette; Arredondo-Olguín, Miguel; Iñiguez, Germán; Castillo-Valenzuela, Oscar
    BACKGROUND: Vitamin D [25(OH)D] is essential for normal bone development and maintenance. Furthermore, its deficiency has been associated with obesity, cardiovascular diseases, insulin resistance, autoimmune diseases, and certain cancers. OBJECTIVE: To determine the incidence of serum 25(OH)D deficiency (<20 ng/ml) among apparently healthy Chilean children (4–14 years old) from three Chilean geographic areas during May–September 2018. MATERIALS AND METHODS: Serum 25(OH)D levels were measured by a competitive protein-binding ELISA assay in 1134 children, and correlations between serum 25(OH)D levels, BMI, and geographic area were calculated. Individuals were grouped according to their serum 25-hydroxyvitamin D levels (ng/ml): severe deficiency: <5; moderate deficiency: 5–10.9; mild deficiency: 11–20.9; insufficiency: 21–29.9 and sufficiency: 30–100. RESULTS: We found 80.4% of children had serum 25(OH)D deficiency, with 1.7% severe, 24.6% moderate, and 54.1% mild. In the three cities, the percentage of serum 25(OH)D deficit was increased when comparing overweight or obesity with a healthy weight. Additionally, an interaction effect was observed between geographic area, nutritional status, and serum 25(OH)D levels using the factorial ANOVA test (p = 0.038). In Antofagasta, there were more overweight children and also a higher percentage of children with VitD deficiency (<30 ng/ml) compared to Santiago or Concepción. CONCLUSION: This study revealed a high prevalence of serum 25(OH)D deficiency in children between 4 and 14 years old in Chile (80.4%) during May–September 2018. Obese and overweight children had the highest prevalence of serum 25(OH)D deficiency.
