We evaluated the relationship between UPF consumption, assessed with the Turkish version of the short Screening Questionnaire of Highly Processed Food Consumption (sQ-HPF), and HbA1c and poor glycemic control in adults with T2DM. Methods: In this single-centre, cross-sectional observational study, 425 adults aged 18\u201365 years with T2DM of at least 6 months\u2019 duration were consecutively recruited at a tertiary general internal medicine outpatient clinic. UPF consumption was assessed with the Turkish sQ-HPF (range 0\u201311; scores \u2265 6 = high UPF consumption). HbA1c was the primary outcome (continuous and dichotomized at 7.0%). Multiple linear and binary logistic regression analyses were performed with hierarchical adjustment for age, sex, body mass index (BMI), diabetes duration, and insulin-based treatment. Results: Total UPF score was positively correlated with HbA1c (r = 0.423, p &lt; 0.001). In the fully adjusted linear model, each one-point increase in total UPF score was associated with a 0.418% higher HbA1c (95% CI: 0.333\u20130.503; \u03b2 = 0.413; p &lt; 0.001), explaining 28.9% of HbA1c variance. In the fully adjusted logistic model, each one-point increase in total UPF score was associated with 25.0% higher odds of poor glycemic control (OR = 1.250, 95% CI: 1.110\u20131.408, p &lt; 0.001). Insulin-based treatment and male sex were also independent predictors. UPF score was not significantly associated with lipid parameters or C-reactive protein. Conclusions: Higher UPF consumption, captured by a brief validated screener, was independently associated with poorer glycemic control in Turkish adults with T2DM. Brief UPF screening may help identify patients who would benefit from targeted nutritional intervention.<\/jats:p>","DOI":"10.3390\/nu18121951","type":"journal-article","created":{"date-parts":[[2026,6,17]],"date-time":"2026-06-17T08:22:56Z","timestamp":1781684576000},"page":"1951","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Ultra-Processed Food Consumption Is Independently Associated with Higher HbA1c and Poor Glycemic Control in Adults with Type 2 Diabetes"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3664-6383","authenticated-orcid":false,"given":"Nezihe","family":"Otay Lule","sequence":"first","affiliation":[{"name":"Department of Nutrition and Dietetics, Faculty of Health Sciences, Gaziantep University, 27310 Gaziantep, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-7541-202X","authenticated-orcid":false,"given":"Serpil","family":"\u015eahin","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Faculty of Medicine, Gaziantep University, 27310 Gaziantep, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3582-9663","authenticated-orcid":false,"given":"Kemal Ozan","family":"Lule","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Faculty of Medicine, Gaziantep University, 27310 Gaziantep, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7858-5123","authenticated-orcid":false,"given":"Hamit","family":"Yildiz","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Faculty of Medicine, Gaziantep University, 27310 Gaziantep, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,6,17]]},"reference":[{"key":"ref_1","unstructured":"Magliano, D.J., Boyko, E.J., and IDF Diabetes Atlas 11th Edition Scientific Committee (2025).
