Rationale: This cross-sectional observational study assessed dietary intake in adults aged over 65 years with Disease-Related Malnutrition (DRM), with specific differentiation of oncology patients. 

Methods: Anthropometric data and two-day dietary survey-based macronutrient intake were analysed in 264 ambulatory patients diagnosed with DRM. Participants were referred to the Clinical Nutrition outpatient clinic and were classified as having oncologic disease (n=177, 67.6%) or other conditions.

Results: The body mass index (BMI) of the total population was 22.35(3.51) kg/m2, with significant (p<0.01) differences between oncologic (22.9(3.48) kg/m2) and others (21.3(3.35) kg/m2; p<0.01). Despite this, relative (over total weight) energetic consumption of the oncologic patients was significantly lower (25.59(7.95) Kcal/Kg) than that observed in the other DRM patients (29.38(10.45) Kcal/Kg). Among oncologic patients, 14.1% presented protein intake <0.8 g/kg and 39.5% between 0.8-1.2 g/kg, while only 20.3% exceeded 1.5 g/kg. In contrast, non-oncologic patients showed lower prevalence of <0.8 g/kg (9.2%) and higher proportions in the 1.2-1.5 g/kg (31%) and >1.5 g/kg (27.6%) ranges. The significantly lower relative protein intake observed in oncologic patients compared with those with other diseases (1.17(0,39) vs. 1.34(0.49) g/kg; p<0.01) was accompanied by a poorer adequacy to both energy requirements (83.46(23.59)% vs. 90.77(28.29)%; p<0.01) and protein requirements (77.92(25.93)% vs. 89.09(33.11)%; p=0.03). 

Conclusion: Protein intake profiles of the studied population of patients with DRM (>65 years old) showed significant differences in total and relative (per weight) values, with poorer protein intake in oncology patients. These results could help in preventing unbalanced dietary patterns in DRM patients, especially when related to oncologic diseases.
