Although emotion-regulation strategies are known to influence eating behavior, evidence on their role in shaping overall diet quality remains scarce, particularly in Central and Eastern European populations. Young adulthood (18\u201330\u202fyears) represents a critical developmental stage in which both mental health vulnerabilities and long-term dietary patterns consolidate, yet no prior study has examined how discrete cognitive emotion-regulation strategies relate to both global diet quality and specific eating behaviors in Czech young adults.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      In the Czech Republic, we conducted a cross-sectional survey of 1,027 young adults (507 men, 520 women; mean age\u202f=\u202f24.6, SD\u202f=\u202f3.3\u202fyears) recruited via quota-based convenience sampling matched to the 2021 census on age (18\u201330\u202fyears), sex, education, and region. Data were collected in three 60-min online sessions. Participants completed validated Czech measures of depression (BDI), anxiety (BAI), psychological distress (SCL-90), burnout (Shirom-Melamed Burnout Measure), and nine CERQ subscales\u2014all demonstrating\n                      <jats:italic>\u03b1<\/jats:italic>\n                      \u202f\u2265\u202f0.89 in prior validations and\n                      <jats:italic>\u03b1<\/jats:italic>\n                      \u202f\u2265\u202f0.79 in our pilot (\n                      <jats:italic>N<\/jats:italic>\n                      \u202f=\u202f50). Diet quality was assessed using a 30-item Czech FFQ (pilot \u03b1\u202f=\u202f0.81), from which Diet Quality Index International (DQI-I) scores were computed. Eating behaviors were measured with the 31-item Czech Adult Eating Behavior Questionnaire (AEBQ; \u03b1_total\u202f=\u202f0.79). We used stepwise multiple regression with all variance inflation factors &amp;lt; 2.0 to identify psychological variables associated with DQI-I and with \u201cfood-approach\u201d versus \u201cfood-avoidance\u201d behaviors, minimizing overfitting.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      In exploratory stepwise regression models (all variance inflation factors &amp;lt; 2.0), the DQI-I model explained a small proportion of variance (Adj R\n                      <jats:sup>2<\/jats:sup>\n                      \u202f=\u202f0.024; f\n                      <jats:sup>2<\/jats:sup>\n                      \u202f=\u202f0.025). Within this model, higher rumination was positively associated with diet quality (B\u202f=\u202f0.34,\n                      <jats:italic>p<\/jats:italic>\n                      \u202f&amp;lt;\u202f0.001), while depressive symptoms were inversely associated with diet quality (B\u202f=\u202f\u22120.09,\n                      <jats:italic>p<\/jats:italic>\n                      \u202f=\u202f0.001). The AEBQ model accounted for a modest but meaningful share of variance (Adj R\n                      <jats:sup>2<\/jats:sup>\n                      \u202f=\u202f0.155; f\n                      <jats:sup>2<\/jats:sup>\n                      \u202f=\u202f0.183). In this model, anxiety, catastrophizing, and \u201cfocus on the positive\u201d were positively associated with food-approach behaviors (all\n                      <jats:italic>p<\/jats:italic>\n                      \u202f&amp;lt;\u202f0.001), whereas positive reappraisal and acceptance negatively associated with dysregulated eating (\n                      <jats:italic>p<\/jats:italic>\n                      \u202f&amp;lt;\u202f0.01).

These findings reveal complex and partly counterintuitive associations\u2014for example, rumination was linked to healthier diet quality, while some ostensibly adaptive strategies coincided with more dysregulated eating. These results should be interpreted as exploratory and hypothesis-generating, underscoring the potential relevance of cognitive-emotional mechanisms for future nutritional psychiatry interventions. Integrating approaches that address maladaptive strategies such as catastrophizing with dietary guidance may represent a promising direction for prevention and health-promotion efforts but requires confirmation in longitudinal and experimental studies.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3389\/fnut.2025.1598260","type":"journal-article","created":{"date-parts":[[2025,11,3]],"date-time":"2025-11-03T14:36:42Z","timestamp":1762180602000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":3,"title":["Exploring the relationship between dietary quality, eating behavior, and mental health among young adults"],"prefix":"10.3389","volume":"12","author":[{"given":"Michaela","family":"Poslt K\u00f6nigov\u00e1","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Martina","family":"Sebalo V\u0148ukov\u00e1","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ivan","family":"Sebalo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Veronika","family":"Koleni\u010dov\u00e1","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lucie","family":"Urbanov\u00e1","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Petra","family":"\u0158eho\u0159kov\u00e1","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Martin","family":"Anders","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2025,11,3]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","first-page":"1213","DOI":"10.1016\/S0140-6736(05)79168-6","article-title":"Fish consumption and major depression","volume":"351","author":"Hibbeln","year":"1998","journal-title":"Lancet"},{"key":"ref2","doi-asserted-by":"publisher","first-page":"1","DOI":"10.1097\/YCO.0000000000000117","article-title":"The gut microbiome and diet in psychiatry focus on depression","volume":"28","author":"Dash","year":"2015","journal-title":"Curr Opin Psychiatry"},{"key":"ref3","first-page":"39","volume-title":"The association between dietary patterns and mental health in early adolescence","author":"Oddy","year":"2009"},{"key":"ref4","doi-asserted-by":"publisher","first-page":"957","DOI":"10.3390\/nu10080957","article-title":"Relationship between diet and mental health in a young adult Appalachian college population","volume":"10","author":"Wattick","year":"2018","journal-title":"Nutrients"},{"key":"ref5","doi-asserted-by":"publisher","first-page":"568937","DOI":"10.3389\/fnins.2020.568937","article-title":"Editorial: nutrients, neurotransmitters and brain energetics","volume":"14","author":"Ximenes-da-Silva","year":"2020","journal-title":"Nutr Neurotrans Brain Energ"},{"key":"ref6","doi-asserted-by":"publisher","first-page":"131","DOI":"10.1080\/23794925.2021.1875342","article-title":"Nutrition provides the essential foundation for optimizing mental health","volume":"6","author":"Rucklidge","year":"2021","journal-title":"Evid-Based Pract Child Adolesc Mental Health"},{"key":"ref7","doi-asserted-by":"publisher","first-page":"88","DOI":"10.21101\/cejph.a6781","article-title":"Regional dietary shifts among Czech young adults: a focus on convenience foods","volume":"30","author":"Kraj\u00ed\u010dek","year":"2022","journal-title":"Cent Eur J Public Health"},{"key":"ref8","first-page":"234","article-title":"From home cooking to fast food: dietary transitions in Czech university students","volume":"14","author":"Novotn\u00fd","year":"2021","journal-title":"Nutr Diet Rev"},{"key":"ref9","doi-asserted-by":"publisher","first-page":"101384","DOI":"10.1016\/j.eatbeh.2020.101384","article-title":"Catastrophizing and stress-induced overeating: an experimental study","volume":"37","author":"S\u00fctterlin","year":"2020","journal-title":"Eat Behav"},{"key":"ref10","doi-asserted-by":"publisher","first-page":"104383","DOI":"10.1016\/j.appet.2019.104383","article-title":"Rumination mediates the relationship between depressive symptoms and emotional eating","volume":"142","author":"Svaldi","year":"2019","journal-title":"Appetite"},{"key":"ref11","doi-asserted-by":"publisher","first-page":"1311","DOI":"10.1016\/S0191-8869(00)00113-6","article-title":"Negative life events, cognitive emotion regulation and emotional problems","volume":"30","author":"Garnefski","year":"2001","journal-title":"Pers Individ Differ"},{"key":"ref12","volume-title":"Population census 2021: Age, sex, education, and regional distributions.
