Objectives: We investigated the nutritional status and clinical outcomes of patients with cancer based on their energy intake after nutritional recommendations.
Methods: This study was a retrospective study. Body weight, nutritional status, dietary intake, and clinical outcomes were collected from medical records. We assessed the data according to energy intake: <50% of the recommended intake was insufficient energy intake (IEI group), 50% to 79% was moderate energy intake (MEI group), and ≥80% was adequate energy intake (AEI group).
Results: A total of 111 patients with cancer were enrolled in the present study. After nutritional recommendation, the number of subjects in the IEI and MEI groups were significantly decreased as patients shifted to the after-AEI group (P < 0.01). A significantly high proportion of patients had lower malnutrition universal screening tool and patient-generated subjective global assessment scores in the after-AEI group (P < 0.01). Subjects in the after-MEI and after-AEI groups showed slight gains in body weight (P = 0.07) and positively correlated with the energy (β = 0.05; P = 0.07) and protein intake (β = 0.04; P = 0.01). Significantly low proportions of patients with cancer died during hospitalization in the after-MEI and after-AEI groups, but significantly high proportions of patients with cancer in the after-MEI and after-AEI groups reached their ideal body weight (P = 0.03) compared with that in the after-IEI group.
Conclusions: Patients with cancer who comply with a moderate energy intake recommendation (50%-79%) within at least 28 d may limit body weight decrease and improve nutritional status and clinical outcomes.
