Abstract
Background: Considering sex-specific factors has become an increasingly recognized area for research and practice. In the field of clinical nutrition, there is insufficient evidence regarding differences in clinical presentation, treatment response, and side effects of nutritional therapy among female and male patients.
Methods: This secondary analysis investigated differences among female and male patients at risk for malnutrition regarding initial presentation, clinical outcomes, and treatment response in patients included in the Effect of Early NutritionalSupporton Frailty, Functional Outcomes, and Recovery of Malnourished Medical Inpatients Trial (EFFORT), a randomized controlled trial comparing individualized nutritional support to usual care.
Results: Of 2,028 patients included in the trial 964 were female and 1,064 were male. The nutritional history and clinical presentation of female patients was different: they consumed less food and had a greater loss of appetite than the male population. Male patients had higher risk for mortality at 180 days (27% compared to 19%, adjusted HR 1.35 [95%CI 1.12, 1.63]) and further adverse clinical outcomes. However, there was no difference in the effect of nutritional support on mortality among female and male patients (HR 0.76 [95%CI 0.45, 1.27] compared to 0.81 [95%CI 0.54, 1.21]; p for interaction =0.939).
Conclusion: Results of this multicenter randomized trial suggest that multimorbid female inpatients, have a different clinical presentation and are more prone to loss of appetite and reduced daily dietary intake compared to male inpatients. Importantly, the favorable response to nutritional interventions was similar in both sexes.
期刊介绍:
American Journal of Clinical Nutrition is recognized as the most highly rated peer-reviewed, primary research journal in nutrition and dietetics.It focuses on publishing the latest research on various topics in nutrition, including but not limited to obesity, vitamins and minerals, nutrition and disease, and energy metabolism.
Purpose:
The purpose of AJCN is to:
Publish original research studies relevant to human and clinical nutrition.
Consider well-controlled clinical studies describing scientific mechanisms, efficacy, and safety of dietary interventions in the context of disease prevention or health benefits.
Encourage public health and epidemiologic studies relevant to human nutrition.
Promote innovative investigations of nutritional questions employing epigenetic, genomic, proteomic, and metabolomic approaches.
Include solicited editorials, book reviews, solicited or unsolicited review articles, invited controversy position papers, and letters to the Editor related to prior AJCN articles.
Peer Review Process:
All submitted material with scientific content undergoes peer review by the Editors or their designees before acceptance for publication.
