Abstract

Background

Children diagnosed with cancer are more susceptible to malnutrition and should receive extra consideration when it comes to nutritional evaluation. It is difficult to analyze nutritional status in children undergoing cancer therapy because there isn't a single, reliable tool. Anthropometric measurements are the most widely used objective tool for evaluating malnutrition in children; but it can be easily affected by disease and treatment, reducing its accuracy for evaluating body composition. The aim of this study was to evaluate the effectiveness of Subjective Global Nutrition Assessment (SGNA) in predicting nutritional status as compared to anthropometric measurements among children with cancer in Pakistan.

Methods

This cross-sectional study was conducted in oncology department of hospitals in Lahore, Pakistan. SGNA along with anthropometric were conducted on children aged 2–18 years receiving oncological treatment. To evaluate agreement between SGNA and anthropometric indicators in identifying malnutrition status, sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) was performed.

Results

In 135 children 68.1 % were identified as having moderate or severe malnutrition according to SGNA. SGNA demonstrated the best performance with MUAC/A, showing a sensitivity of 85.7 %, specificity of 47.2 %, PPV of 58.7 %, and NPV of 88.1 %. But the agreement between SGNA and objective measures was only fair.

Conclusion

The SGNA proved useful for assessing the nutritional status of children with cancer and was effective in monitoring the prevalence of malnutrition when compared to objective nutritional evaluation methods.

主观整体营养评估（SGNA）在预测癌症儿童营养状况中的表现：一项横断面研究

被诊断患有癌症的儿童更容易营养不良，在营养评估方面应该得到额外的考虑。很难分析接受癌症治疗的儿童的营养状况，因为没有一个单一的、可靠的工具。人体测量是评估儿童营养不良最广泛使用的客观工具；但它很容易受到疾病和治疗的影响，从而降低了其评估身体成分的准确性。本研究的目的是评估主观全球营养评估（SGNA）在预测巴基斯坦癌症儿童营养状况方面的有效性，并将其与人体测量测量相比较。方法横断面研究在巴基斯坦拉合尔医院肿瘤科进行。对接受肿瘤治疗的2-18岁儿童进行SGNA和人体测量。为了评估SGNA和人体测量指标在识别营养不良状况方面的一致性，对敏感性、特异性、阳性预测值（PPV）和阴性预测值（NPV）进行了评估。结果135例患儿中68.1 %根据SGNA诊断为中度或重度营养不良。SGNA在MUAC/A中表现最好，敏感性为85.7 %，特异性为47.2 %，PPV为58.7 %，NPV为88.1 %。但SGNA与客观措施之间的协议是公平的。结论与客观营养评价方法相比，SGNA可用于评估癌症儿童的营养状况，并能有效监测营养不良的发生率。
