Although Chile ranks among the highest consumers of UPFs in Latin America, studies using primary dietary data, especially among older adults, are scarce. This study aimed to describe the food intake of Chilean older adults according to the degree of food processing, and to explore the association between UPF intake and sociodemographic, economic and health factors. Methods: A cross-sectional study of 434 non-institutionalized older adults (\u226560 years) living in the Metropolitan Region of Chile was conducted. Dietary intake was assessed using interviewer-administered 24h recall, with a second assessment 8\u201315 days later in a random subsample (n = 60). Foods were classified according to the NOVA system into minimally processed foods (MPFs), culinary ingredients, processed foods (PF), or UPF. Usual energy intake was estimated using the MSM. Sociodemographic (sex, age, area), economic (income, education, health system), and health-related variables (chronic conditions, sedentary lifestyle, tobacco use) were collected through home-visit questionnaires. Anthropometric and functional measurements were taken by trained nutritionists. The association between UPF intake and studied variables was evaluated using multivariate fractional probit regression, with mean marginal effects presented. Results: Most of the participants were women (86.2%), aged 70\u201379 years (47.9%), and residents of urban areas (76.3%). Most of their calories came from MPF (45.7%), followed by PF (25.5%) and UPF (16.6%). Higher UPF intake was associated with living in an urban area (+3.8%; 95% CI 1.2\u20136.3%), higher education (+3.5%; 95% CI 1.1\u20136.0%), and being affiliated with the private health system (+9.1%; 95% CI 4.1\u201314.0%). Conclusions: In this community-based sample of Chilean older adults, UPF intake was associated with socioeconomic factors but not health status.<\/jats:p>","DOI":"10.3390\/nu18121899","type":"journal-article","created":{"date-parts":[[2026,6,12]],"date-time":"2026-06-12T06:53:10Z","timestamp":1781247190000},"page":"1899","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Sociodemographic, Economic, and Health Factors Associated with Ultra-Processed Food Intake Among Older Adults in Chile"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4317-4601","authenticated-orcid":false,"given":"Daiana","family":"Quintiliano-Scarpelli","sequence":"first","affiliation":[{"name":"Nutrition and Dietetics Program, Faculty of Medicine, Cl\u00ednica Alemana\u2013Universidad del Desarrollo, Avenida La Plaza 680, Las Condes, Santiago 7610658, Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2577-880X","authenticated-orcid":false,"given":"Leticia de Albuquerque","family":"Ara\u00fajo","sequence":"additional","affiliation":[{"name":"Nutrition and Dietetics School, Faculty of Health Sciences, Catholic University of Maule, Curic\u00f3 3340000, Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3643-302X","authenticated-orcid":false,"given":"Camila","family":"Zancheta Ricardo","sequence":"additional","affiliation":[{"name":"Center of Research in Food Environment and Prevention of Obesity and Non-Communicable Diseases (CIAPEC), Institute of Nutrition and Food Technology (INTA), University of Chile, Santiago 7830490, Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,6,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"21","DOI":"10.1111\/obr.12107","article-title":"Ultra-processed products are becoming dominant in the global food system","volume":"14","author":"Monteiro","year":"2013","journal-title":"Obes.
