Methods: Questionnaires distributed among 1611 subjects included questions concerning sociodemographic factors, dietary and hygiene knowledge and behaviors, and dental visits. Spearman\u2019s rank correlation and a bivariate and multivariate logistic regression analysis was conducted; odds ratios (ORs) and adjusted odds ratios (AORs) were calculated (p \u2264 0.05). Results: Respondents self-assessed their oral health knowledge; 63.1% of them considered it to be limited, and 40.7% understood the cariogenic effect of frequent snacking. Dentists and a dental team (DT) were the main source of information (55.7%). Dietary advice was recommended by 10.8% of dentists and the DT, while check-up appointments were advised by 49.2%. Parents\u2019 higher education contributed to a lower intake of cariogenic food. This effect was stronger for the mother\u2019s education. Dental appointments scheduled twice a year increased the chances of consuming healthy food (A2OR = 1.21 (1.07\u20132.11); p = 0.0028). Being informed increased the chances of toothbrushing \u2265 2 times (OR: 1.21, CI 1.10\u20131.46), using fluoridated toothpaste (OR: 1.26 CI1.05\u20131.55), and the frequency of appointments (A1OR: 1.56 CI 1.21\u20131.87; A2OR: 1.78 CI 1.54\u20131.91). Conclusions: Knowledge and oral health related behaviors, as well as the involvement of the dental team in education, are inadequate. Education and instruction in the dental office has a favorable influence on oral-health-related behaviors. It is, therefore, necessary to undertake systemic solutions so that dental practitioners are more involved. Providing oral health knowledge should be the standard of care.<\/jats:p>","DOI":"10.3390\/nu17050871","type":"journal-article","created":{"date-parts":[[2025,2,28]],"date-time":"2025-02-28T10:46:46Z","timestamp":1740739606000},"page":"871","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Dietary and Hygiene-Related Knowledge Versus Reported Behaviors of Eighteen-Year-Olds: A Nationwide Cross-Sectional Study"],"prefix":"10.3390","volume":"17","author":[{"given":"Dorota","family":"Olczak-Kowalczyk","sequence":"first","affiliation":[{"name":"Department of Paediatric Dentistry, Medical University of Warsaw, ul. \u017bwirki i Wigury 61, 02-091 Warsaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9773-7313","authenticated-orcid":false,"given":"Marcin","family":"Studnicki","sequence":"additional","affiliation":[{"name":"Department of Biometry, Warsaw University of Life Sciences, Nowoursynowska 166, 02-787 Warsaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0248-6625","authenticated-orcid":false,"given":"Anna","family":"Turska-Szybka","sequence":"additional","affiliation":[{"name":"Department of Paediatric Dentistry, Medical University of Warsaw, ul. \u017bwirki i Wigury 61, 02-091 Warsaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,2,28]]},"reference":[{"key":"ref_1","unstructured":"American Academy of Pediatric Dentistry (2024, December 14).
