Item type:Publication, Socioeconomic inequalities in Chile during the COVID-19 pandemic: A regional analysis of income poverty(Public Library of Science (PLoS), 2025-05-07); ;Sushma Dahal; ; Svenn-Erik MamelundThe COVID-19 pandemic caused an unprecedented economic crisis, intensifying poverty levels in Latin America, particularly in Chile. This study examines the short- and long-term socioeconomic impacts of COVID-19 on income poverty in Chile, focusing on regional disparities, rurality, ethnicity, educational attainment, and immigration. Using data from the Chile National Socioeconomic Characterization Survey (CASEN) for 2017, 2020, and 2022, we analyzed poverty trends across the pre-pandemic, pandemic, and post-pandemic periods. We employed spatial clustering techniques with Local Moran’s I to detect poverty hotspots and applied logistic regression models to identify key sociodemographic factors associated with these hotspots. Our results reveal stark regional disparities, with disproportionately higher poverty rates among rural populations, Indigenous communities, and individuals with lower education levels or immigrant backgrounds. The proportion of individuals in poverty hotspots rose from 6.8% in 2017 to 8.6% in 2020, before slightly declining to 7.7% in 2022. Although emergency monetary subsidies helped reduce overall poverty from 10.8% in 2020 to 6.5% in 2022, these measures were insufficient to address deep-rooted structural inequalities. Our findings underscore the urgent need for targeted, long-term policies that go beyond temporary financial assistance and tackle systemic disparities linked to rurality, ethnicity, education, and immigration. Such measures are essential for achieving sustainable poverty reduction and fostering inclusive economic growth in Chile.Scopus© Citations 1 1 - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Identification of clinical phenotypes of peripheral involvement in patients with spondyloarthritis, including psoriatic arthritis: a cluster analysis in the worldwide ASAS-PerSpA study(2021) ;Clementina López-Medina ;Sylvie Chevret ;Anna Molto ;Joachim SieperTuncay Duruöz<jats:sec><jats:title>Objective</jats:title><jats:p>To identify clusters of peripheral involvement according to the specific location of peripheral manifestations (ie, arthritis, enthesitis and dactylitis) in patients with spondyloarthritis (SpA) including psoriatic arthritis (PsA), and to evaluate whether these clusters correspond with the clinical diagnosis of a rheumatologist.</jats:p></jats:sec><jats:sec><jats:title>Methods</jats:title><jats:p>Cross-sectional study with 24 participating countries. Consecutive patients diagnosed by their rheumatologist as PsA, axial SpA or peripheral SpA were enrolled. Four different cluster analyses were conducted: one using information on the specific location from all the peripheral manifestations, and a cluster analysis for each peripheral manifestation, separately. Multiple correspondence analyses and k-means clustering methods were used. Distribution of peripheral manifestations and clinical characteristics were compared across the different clusters.</jats:p></jats:sec><jats:sec><jats:title>Results</jats:title><jats:p>The different cluster analyses performed in the 4465 patients clearly distinguished a predominantly axial phenotype (cluster 1) and a predominantly peripheral phenotype (cluster 2). In the predominantly axial phenotype, hip involvement and lower limb large joint arthritis, heel enthesitis and lack of dactylitis were more prevalent. In the predominantly peripheral phenotype, different subgroups were distinguished based on the type and location of peripheral involvement: a predominantly involvement of upper versus lower limbs joints, a predominantly axial enthesitis versus peripheral enthesitis, and predominantly finger versus toe involvement in dactylitis. A poor agreement between the clusters and the rheumatologist‘s diagnosis as well as with the classification criteria was found.</jats:p></jats:sec><jats:sec><jats:title>Conclusion</jats:title><jats:p>These results suggest the presence of two main phenotypes (predominantly axial and predominantly peripheral) based on the presence and location of the peripheral manifestations.</jats:p></jats:sec>6Scopus© Citations 18 - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Compliance with the smoking ban in enclosed, semiopen and open areas of workplaces and public places in Chile(2020); ;Xaviera Molina; ; <jats:sec><jats:title>Objective</jats:title><jats:p>To assess the national level of compliance with the Chilean comprehensive smoke-free legislation by observing healthcare facilities, education centres, government offices, hospitality venues and private workplaces, by type of area within workplaces and public places: enclosed, semiopen and open.</jats:p></jats:sec><jats:sec><jats:title>Methodology</jats:title><jats:p>In this cross-sectional observational study, we studied a national representative sample of 3253 venues obtained through a two-stage cluster sampling design. First, 57 municipalities were randomly selected, proportionally to the total number of venues of interest. Second, within each selected municipality, a maximum of 12 venues of each sector was selected systematically from a list of existing sites. We determined the non-compliance level by estimating the percentage of the visited venues where smoking was observed or suspected in banned areas of the premises.</jats:p></jats:sec><jats:sec><jats:title>Results</jats:title><jats:p>Smoking or suspicion thereof was not observed in any enclosed area of any establishment. However, smoking violations were observed in semiopen areas ranging from less than 0.5% of schools and healthcare centres to around 10% of hospitality venues or 23.0% of higher education centres. Smoking violations were also observed in outdoor areas of 6.7% and 1.6% of the health centres and schools, respectively.</jats:p></jats:sec><jats:sec><jats:title>Discussion</jats:title><jats:p>The stark contrast in compliance with the smoking ban between the enclosed areas and the semiopen areas may be a consequence of the complex definition of semiopen areas in the regulations. The study also reflects the need to improve the overall enforcement of the smoke-free law, particularly in universities and hospitality venues.</jats:p></jats:sec>Scopus© Citations 6 1 - Some of the metrics are blocked by yourconsent settings

Item type:Publication, The Unplugged program in Chile (“Yo Sé Lo Que Quiero”) for substance use prevention among early adolescents: study protocol for a randomized controlled trial(2022) ;Jorge Gaete ;Saray Ramírez ;Sofía Gana ;Daniela ValenzuelaRicardo Araya<jats:title>Abstract</jats:title><jats:sec> <jats:title>Background</jats:title> <jats:p>Substance use is among the main contributors to disease among children and adolescents in the Americas region. The call for effective prevention of substance use among adolescents has resulted in numerous school-based programs, and particularly the Unplugged program has been proved to be successful in reducing the prevalence of different substances in seven European countries. The purpose of this study is to test the effectiveness of the Unplugged program in Chile (“Yo Sé Lo Que Quiero”).</jats:p> </jats:sec><jats:sec> <jats:title>Methods</jats:title> <jats:p>This is a cluster randomized controlled trial, parallel-group type, where “Yo Sé Lo Que Quiero” is compared to standard school preventive curricula in control schools. A total of 70 schools and 8400 adolescents are expected to be randomized with 1:1 allocation. During formative work, the Unplugged program was culturally adapted to Chile, and the instrument to assess the primary and secondary outcomes was validated. The effectiveness of this program will be assessed using the European Drug Addiction Prevention Trial Questionnaire (EU-Dap), measuring substance use prevalence and risk and protective factors in baseline, post-intervention, and four months after the end of the intervention.</jats:p> </jats:sec><jats:sec> <jats:title>Discussion</jats:title> <jats:p>The proposed study will be the first to test the effectiveness of a school-based substance use prevention program in Chile in a cluster randomized control trial and the first study evaluating the Unplugged program in Spanish-speaking Latin America. A model for disseminating the Unplugged program inside Europe already exists and has been implemented successfully in several countries. Thus, if the effects of the program are positive, wide implementation in Chile and Latin American countries is possible soon.</jats:p> </jats:sec><jats:sec> <jats:title>Trial registration</jats:title> <jats:p><jats:ext-link xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="uri" xlink:href="https://clinicaltrials.gov/ct2/show/NCT04236999">ClinicalTrials.gov</jats:ext-link><jats:ext-link xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="uri" xlink:href="https://clinicaltrials.gov/ct2/show/NCT04236999">NCT04236999</jats:ext-link>.
