High prevalence of malnutrition and nutrition impact symptoms in older patients with cancer: Results of a Brazilian multicenter study.

Background: Malnutrition in cancer is an independent factor associated with negative clinical outcomes. The objective of this study was to evaluate the prevalence of malnutrition across different age groups in patients with cancer in Brazil and to identify associations with nutrition impact symptoms (NIS).

Methods: In this observational, cross-sectional, multicenter study, the authors evaluated 4783 patients with cancer aged ≥20 years who were admitted to 45 public hospitals in Brazil. Nutritional status, nutritional risk, and NIS were evaluated using the Patient-Generated Subjective Global Assessment.

Results: More than one-fourth (25.5%) of all participants were aged ≥65 years. In patients aged ≥65 years, the prevalence of moderate/suspected and severe malnutrition was 55%, it was 45.4% in those aged 51 to 64 years, and it was 36.1% in those aged ≤50 years. Among the NIS with a higher risk of occurrence in patients aged ≥65 years were no appetite (odds ratio [OR], 1.90; 95% CI, 1.62-2.22; P < .05) and dry mouth (OR, 1.40; 95% CI, 1.1-1.67; P < .05). In patients between ages 51 and 64 years, compared with those aged ≤50 years, the NIS with a higher risk of occurrence were no appetite (OR, 1.45; 95% CI, 1.23-1.69; P < .05), dry mouth (OR, 1.22; 95% CI, 1.02-1.45; P < .05), and problems with swallowing (OR, 1.56; 95% CI, 1.25-1.96; P < .05).

Conclusions: The prevalence of malnutrition and the occurrence of NIS are high in hospitalized Brazilian patients aged ≥65 years who have cancer. The occurrence of NIS was higher in the population aged >50 years than in those aged ≤50 years. Nutritional screening and assessment should be performed immediately after hospitalization to enable early diagnosis and multidisciplinary or interdisciplinary intervention(s).
