This study aimed to assess food consumption frequency and age, gender, and socio-demographic differences in dietary patterns among schoolchildren aged 7\u201317 years in Karaganda, Kazakhstan. Methods: A cross-sectional study was conducted among schoolchildren aged 7\u201317 years attending state secondary schools in Karaganda, Kazakhstan, from September 2025 to February 2026. Food consumption frequency was assessed using a bilingual Russian\u2013Kazakh questionnaire developed by the authors based on food frequency questionnaire approaches and adapted to the Kazakhstani context; the questionnaire included 41 food items, including national meat products and traditional fermented milk drinks, and Principal Component Analysis was applied to identify dietary patterns. Results: A total of 864 schoolchildren aged 7\u201317 years were included in the study, with comparable distribution by sex and age groups. Frequent consumption of fast food, coffee, processed and canned meat products increased markedly with age, while consumption of milk, fermented dairy products, juices, fresh fish and berries was lower, especially among older adolescents. Principal Component Analysis identified three dietary patterns\u2014\u201cprocessed and fast-food\u201d, \u201ctraditional meat-based\u201d, and \u201cmixed dairy-based pattern\u201d\u2014with the processed and fast-food pattern more strongly associated with older age, non-Kazakh ethnicity, and school location in the South-East district. Conclusions: The findings indicate age-related shifts toward less balanced dietary choices among Karaganda schoolchildren, particularly among adolescents, supporting the need for targeted school- and family-based interventions to reduce fast food, sugary drink, coffee, and processed meat consumption while promoting healthier food choices.<\/jats:p>","DOI":"10.3390\/nu18172774","type":"journal-article","created":{"date-parts":[[2026,8,25]],"date-time":"2026-08-25T10:04:55Z","timestamp":1787652295000},"page":"2774","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Assessment of Food Consumption Frequency Among Schoolchildren: Cross-Sectional Study from an Urbanized Region of Central Kazakhstan"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5239-2566","authenticated-orcid":false,"given":"Svetlana","family":"Rogova","sequence":"first","affiliation":[{"name":"School of Public Health, Karaganda Medical University, Karaganda 100008, Kazakhstan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5624-9943","authenticated-orcid":false,"given":"Zhanerke","family":"Bolatova","sequence":"additional","affiliation":[{"name":"School of Residency and Professional Development, Karaganda Medical University, Karaganda 100008, Kazakhstan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4463-6874","authenticated-orcid":false,"given":"Karina","family":"Nukeshtayeva","sequence":"additional","affiliation":[{"name":"School of Public Health, Karaganda Medical University, Karaganda 100008, Kazakhstan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Olzhas","family":"Zhamantayev","sequence":"additional","affiliation":[{"name":"School of Public Health, Karaganda Medical University, Karaganda 100008, Kazakhstan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9813-2236","authenticated-orcid":false,"given":"Gaukhar","family":"Kayupova","sequence":"additional","affiliation":[{"name":"School of Public Health, Karaganda Medical University, Karaganda 100008, Kazakhstan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7447-0895","authenticated-orcid":false,"given":"Aza","family":"Galayeva","sequence":"additional","affiliation":[{"name":"School of Public Health, Karaganda Medical University, Karaganda 100008, Kazakhstan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nurzhamal","family":"Shintayeva","sequence":"additional","affiliation":[{"name":"School of Public Health, Karaganda Medical University, Karaganda 100008, Kazakhstan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0696-3516","authenticated-orcid":false,"given":"Olga","family":"Plotnikova","sequence":"additional","affiliation":[{"name":"Department of Occupational Hygiene and Occupational Pathology, Omsk State Medical University, Omsk 644099, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6298-4872","authenticated-orcid":false,"given":"Denis","family":"Turchaninov","sequence":"additional","affiliation":[{"name":"Department of Hygiene and Human Nutrition, Omsk State Medical University, Omsk 644099, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,8,25]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2011","DOI":"10.1017\/S0007114522002781","article-title":"Food and nutrient intakes and compliance with recommendations in school-aged children in Ireland: Findings from the National Children\u2019s Food Survey II (2017\u20132018) and changes since 2003\u20132004","volume":"129","author":"Kehoe","year":"2023","journal-title":"Br.
