Significant heterogeneity was observed across different disease subtypes, with multiple myeloma having the highest prevalence of nutritional risk (66.3%) and leukemia having the highest prevalence of malnutrition (44.9%). Female gender, diabetes, hypertension, elevated C-reactive protein, infection, and low serum albumin levels were independent risk factors associated with malnutrition. Only 15.6% of patients received nutritional support; fewer than one-third of malnourished patients received nutritional intervention, while 7.0% of well-nourished patients received nutritional support without clear indications.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>There is significant heterogeneity in the nutritional status of hospitalized patients with hematologic malignancies, and a marked mismatch exists between nutritional needs and nutritional support.
