Item type:Publication, Exposure of 4-year to 24-year olds to tobacco imagery on prime-time Chilean television(2021); ; ; <jats:sec><jats:title>Introduction</jats:title><jats:p>The extent of the population’s exposure to tobacco imagery across all genres of regular TV programming and the contribution of each of these genres is unknown, except for UK broadcast channels. The objective of this study is to estimate the exposure of young people to tobacco imagery on Chilean prime-time television and the programme source contributing to such exposure.</jats:p></jats:sec><jats:sec><jats:title>Methods</jats:title><jats:p>Programmes aired during 3 weeks in 2019 from the 15 highest audience channels in Chile were content-analysed for the occurrence of tobacco categorised as actual use, implied use, tobacco paraphernalia, tobacco brand appearances and whether they violated Chilean smoke-free law for each 1 min interval (92 639). The exposure of young people to tobacco content was estimated using media viewership figures.</jats:p></jats:sec><jats:sec><jats:title>Results</jats:title><jats:p>Young people received 29, 11 and 4 million tobacco impressions of any type, explicit use and smoke-free violation, respectively, at a rate of 21.8, 8.0 and 2.1 thousand impressions per hour of TV viewing. The main sources of exposure to tobacco impressions were feature films and animated productions, which were almost entirely non-Chilean. Finally, young people were exposed to tobacco brand impressions primarily through films, effectively circumventing the advertising ban in Chile.</jats:p></jats:sec><jats:sec><jats:title>Discussion</jats:title><jats:p>Television programming is a source of significant youth exposure to tobacco imagery, including branding impressions. To conform to the WHO FCTC, Chile should prohibit tobacco branding in any TV programme and require strong anti-tobacco advertisements prior to any TV programme portraying tobacco.</jats:p></jats:sec>23Scopus© Citations 3 - Some of the metrics are blocked by yourconsent settings

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); ; ; 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, Poverty and ethnic patterns in COVID-19 excess mortality: evidence from Chile, 2020-2022(Oxford University Press (OUP), 2025-12-10); ; Elienai Joaquin-DamasThe COVID-19 pandemic highlighted deep-rooted health inequities globally, with marginalized populations showing disproportionate disease burden. We employed Serfling regression models and multivariable analyses to estimate excess mortality across geographic, demographic, and poverty groups from 2020 to 2022 in Chile. Elderly populations (80+ years) experienced the highest excess mortality (267.35 per 10 000 population), more than 8 times higher than those under 80 years (30.80 per 10 000 population). Multivariable linear regression models showed both Indigenous proportion (coefficient = 53.66, P &lt; .001) and elderly population proportion (coefficient = 5.68, P &lt; .01) as the strong predictors of comuna level excess mortality. Poverty correlated significantly with excess mortality (r = 0.23, P &lt; .001) but this association weakened after adjustment for other covariates in multivariable models. Excess mortality peaked in 2021 rather than in 2020 for most groups, with males initially experiencing higher rates during early pandemic waves. Spatial analyses revealed statistically significant clustering (Moran’s I = 0.119, P &lt; .001) with identifiable hotspots in northern Chile and parts of the south. These findings indicated persistent mortality disparities by age and Indigenous status, independent of poverty, and highlight the urgent need for equity-focused pandemic preparedness. An effective pandemic response should integrate biomedical measures, such as vaccination, with culturally grounded strategies that address structural barriers and the broader social determinants of health.</jats:p>1 - Some of the metrics are blocked by yourconsent settings
