  "abstract": "Background: Overweight and obesity are important public-health concerns among young adults. University students experience changes in dietary, physical-activity, sleep, and other health behaviors, but evidence from Saudi university populations remains heterogeneous.\n\nObjective: To explore associations between BMI and selected dietary, physical-activity, sleep, and sociodemographic characteristics among university students.\n\nMethods: This cross-sectional study analyzed electronic questionnaire responses collected from January to April 2025 on a sample of 196 students. Weight and height were self-reported and BMI was recalculated as weight (kg)/height ² (m ² ). BMI was categorized as underweight (&lt;18.5), normal (18.5 to &lt;24.9), overweight (25 to &lt;30), or obesity (≥30 kg/m ² ). Associations were examined using contingency-table analyses and limited exploratory multivariable linear and logistic regression models.\n\nResults: Among 196 analyzed students, 17 (8.7%) were underweight, 106 (54.1%) had normal BMI, 38 (19.4%) were overweight, and 35 (17.9%) had obesity; thus, 73 (37.2%) had overweight or obesity. Associations of BMI category with lifestyle were not statistically significant. Electronic-device use before bed showed a sparse-cell association ( χ ² =23.438, df = 9, Monte Carlo p = 0.010) that should be considered exploratory. In adjusted linear regression, male sex ( β = 5.26 kg/m ² , 95% CI 2.36–8.16, p &lt; 0.001), and students aged &gt;23 years had higher BMI ( β = 2.86, 95% CI 0.44–5.29, p = 0.021). In adjusted logistic regression, male sex (OR = 2.71, 95% CI 1.19–6.19, p = 0.018) and age &gt;23 years (OR = 3.15, 95% CI 1.17–8.43, p = 0.023) were associated with overweight/obesity.\n\nConclusion: Overweight and obesity were common. Gender and age showed associations with BMI status, whereas evidence for independent associations of the selected lifestyle measures was limited and imprecise. The cross-sectional design and self-reported measurements preclude causal inference",
