摘要

目的：应用随机森林算法和logistic回归分析影响神经外科围手术期患者营养不良的因素。方法：对上海市8家三级甲等综合医院330例围手术期神经外科患者进行横断面调查。采用随机森林算法对可能影响营养不良的自变量的重要性进行排序，并将排名前8位的变量纳入逻辑回归模型。结果：随机森林算法确定了总蛋白水平、白蛋白前水平、红细胞压积、血红蛋白水平、CRP水平、糖化血红蛋白水平、腿围和中性粒细胞计数是影响营养状况的主要因素。Logistic回归分析显示，HBA1c水平是营养不良的危险因素（OR=1.316, 95%CI:1.066 ~ 1.624）。结论：建议加强营养支持和糖尿病管理，并对高危人群实施早期营养干预，以降低营养不良风险。

Analysis of influencing factors of malnutrition in perioperative neurosurgery patients — A cross-sectional survey

Objective

This study aimed to analyze the factors influencing malnutrition in perioperative neurosurgery patients using the random forest algorithm and logistic regression.

Methods

A cross-sectional survey was conducted among 330 perioperative neurosurgery patients from eight Class A tertiary general hospitals in Shanghai. The random forest algorithm was employed to rank the importance of independent variables potentially affecting malnutrition, and the top eight variables were subsequently included in a logistic regression model.

Results

The random forest algorithm identified total protein level, prealbumin level, hematocrit, hemoglobin level, CRP level, glycosylated hemoglobin level, leg circumference, and neutrophil count as the primary factors influencing nutritional status. Logistic regression analysis showed that HBA1c level was a risk factor for malnutritional (OR = 1.316, 95%CI:1.066–1.624, P < 0.05), while total protein level (OR = 0.869, 95%CI:0.826–0.915, P < 0.001), hematocrit volume (OR = 0.848, 95%CI: 0.740–0.972, P = 0.019), and calf circumference (OR = 0.887, 95%CI: 0.789–0.997, P = 0.045) were protective factors.

Conclusion

It is recommended to enhance nutrition support and diabetes management, along with implement early nutrition intervention for high-risk groups, to mitigate the risk of malnutrition.

期刊介绍： Clinical Nutrition ESPEN is an electronic-only journal and is an official publication of the European Society for Clinical Nutrition and Metabolism (ESPEN). Nutrition and nutritional care have gained wide clinical and scientific interest during the past decades. The increasing knowledge of metabolic disturbances and nutritional assessment in chronic and acute diseases has stimulated rapid advances in design, development and clinical application of nutritional support. The aims of ESPEN are to encourage the rapid diffusion of knowledge and its application in the field of clinical nutrition and metabolism. Published bimonthly, Clinical Nutrition ESPEN focuses on publishing articles on the relationship between nutrition and disease in the setting of basic science and clinical practice. Clinical Nutrition ESPEN is available to all members of ESPEN and to all subscribers of Clinical Nutrition.
