目的 探讨主观全面营养评估工具(SGNA)评估结果与人体测量指标的相关性，以及其对住院神经损伤患儿进行营养评估的临床有效性。方法 以2019年1月—10月住院的1 466例神经损伤患儿为研究对象，应用SGNA对其进行营养评估，使用WHO推荐的人体测量Z值评分法来验证SGNA对神经损伤患儿营养评估的有效性。结果 以SGNA评估的中、重度养不良及营养不良总体发生率分别为15.14%、3.27%、18.41%。以身高别体重Z评分(WHZ)、年龄别体重Z评分(WAZ)、年龄别身高Z评分(HAZ)及综合Z值为标准评估的营养不良发生率分别为9.69%、12.48%、10.10%和21.56%。以WAZ作为参照标准，SGNA的灵敏度、特异度、约登指数分别为86.62%、88.90%、0.76。以综合Z值评分法作为参照标准，这些分别为57.28%、92.27%、0.50。SGNA与WHZ、综合Z值之间均具有中度一致性(Kappa=0.53、0.523，P均<0.001)。SGNA评估结果与WAZ和WHZ之间相关系数为-0.52、-0.45。结论 SGNA是有别于人体测量更为全面的营养评估方法，可以作为神经损伤患儿可靠的营养评估工具。

Objective This study aimed to investigate the correlation between the Subjective Global Nutritional Assessment Tool (SGNA) and anthropometric measurements, as well as to evaluate its clinical efficacy in assessing the nutritional status of hospitalized children with neurological impairments. Methods A retrospective analysis of 1466 pediatric patients with neurological impairments admitted to the Department of Children’s Rehabilitation were conducted from January 2019 to October 2019. Nutritional status was evaluated using the SGNA, and its effectiveness was corroborated against the World Health Organization's recommended anthropometric Z-score method. Results The prevalence of moderate and severe malnutrition, as well as overall malnutrition, as determined by SGNA, were 15.14%, 3.27%, and 18.41%, respectively. In comparison, the rates identified using weight-for-height Z-score (WHZ), weight-for-age Z-score (WAZ), height-for-age Z-score (HAZ), and composite Z-score were 9.69%, 12.48%, 10.10%, and 21.56%, respectively. When using WAZ as the benchmark, the sensitivity, specificity, and Youden’s index for SGNA were 86.62%, 88.90%, and 0.76, respectively. With the composite Z-score as the reference, these values were 57.28%, 92.27%, and 0.50, respectively. A moderate level of agreement was observed between SGNA and both WHZ and the comprehensive Z-score (Kappa values of 0.53 and 0.523, both P<0.001). The SGNA assessment demonstrated significant correlations with both the WAZ and WHZ, with correlation coefficients of -0.52 and -0.45, respectively. Conclusion The SGNA emerges as a comprehensive nutritional assessment instrument that surpasses anthropometry in scope and can be reliably utilized for nutritional assessment in children with neurological impairments.
