Understanding these associations is essential for addressing iron deficiency and cardiovascular risk in this population. Methods: We conducted a cross-sectional study using data from 13,778 Qatari adults enrolled in the Qatar Biobank (men: n = 5770; women: n = 8008). Red meat intake was assessed via the Food Frequency Questionnaire and categorized as low (\u22641\/month), moderate (2\u20134\/month), and high (\u22655\/month) intake. Hematological and metabolic biomarkers were analyzed. Two-sample t-tests compared biomarker levels by gender. Multiple linear regression examined associations between red meat intake and iron profile indicators, adjusting for age, gender, supplement use, diabetes, hypercholesterolemia, and hypertension. Results: High red meat consumption was associated with increased ferritin (Coef = 134.685, p &lt; 0.001) and hemoglobin (Coef = 0.918, p = 0.017). Males showed higher hemoglobin (14.8\u201314.9 vs. 12.4\u201312.5 g\/dL, p &lt; 0.0001) and total cholesterol (5.17 \u00b1 1.10 vs. 5.02 \u00b1 1.01 mmol\/L, p = 0.0125). TIBC showed no significant gender differences across categories (p &gt; 0.15) but varied significantly within each gender across red meat consumption categories (males: p &lt; 0.0000; females: p &lt; 0.0000). Conclusions: Higher red meat intake is associated with improved iron status, particularly ferritin levels, and gender-specific effects on hemoglobin and cholesterol levels. Moderate red meat intake may support iron health while maintaining a favorable lipid profile.<\/jats:p>","DOI":"10.3390\/foods14122134","type":"journal-article","created":{"date-parts":[[2025,6,18]],"date-time":"2025-06-18T09:36:00Z","timestamp":1750239360000},"page":"2134","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Red Meat Consumption, Iron Status, and Cardiometabolic Risk in Qatari Adults: A Cross-Sectional Gender-Stratified Analysis from the QPHI-QBB Data in Qatar"],"prefix":"10.3390","volume":"14","author":[{"given":"Hanaa","family":"Mousa","sequence":"first","affiliation":[{"name":"Vice President for Health and Medical Sciences Office, QU Health, Qatar University, Doha 2713, Qatar"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nadin M.","family":"Abdel Razeq","sequence":"additional","affiliation":[{"name":"College of Nursing, QU Health, Qatar University, Doha 2713, Qatar"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-8307-787X","authenticated-orcid":false,"given":"Yasmen","family":"Khial","sequence":"additional","affiliation":[{"name":"Nutrition Sciences Department, College of Health Sciences, QU Health, Qatar University, Doha 2713, Qatar"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Reema","family":"Tayyem","sequence":"additional","affiliation":[{"name":"Nutrition Sciences Department, College of Health Sciences, QU Health, Qatar University, Doha 2713, Qatar"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,6,18]]},"reference":[{"key":"ref_1","first-page":"303","article-title":"Heme iron in meat as the main source of iron in the human diet","volume":"21","author":"Janicki","year":"2016","journal-title":"J.
