BACKGROUND/AIMS: We aimed to perform the validity and reliability analysis of the Turkish version of the Pediatric Nutritional Risk Score (PNRS).
The study group consisted of 149 patients aged between 1 month and 18 years who were admitted to the hospital for at least 48 h. The patients' age, gender, anthropometric measurements, length of stay, admission diagnosis, daily body weights, food consumption, and pain status were recorded. Backward and forward translations into Turkish were done. PNRS was performed by two different physicians. The consistency of the PNRS results was evaluated to determine the validity of PNRS. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were calculated.
Of all patients, 69 (46.3%) were female and 80 (53.7%) were male. The mean length of the stay was 7.3±4.0 days. The mean age of the patients was 51.9±63.6 months. The Kappa coefficient between the two physicians was 0.66. Weight loss was observed in 65.2% of the patients in the high-risk group and 25.4% in the low-risk group. The hospital malnutrition rate was 31.5%. A higher risk was identified in those with <50% food intake and more severe disease. The specificity, sensitivity, NPV, and PPV of PNRS were 82.1%, 77.8%, 92.0%, and 58.3%, respectively.
A good consistency suggests that the Turkish validation was achieved successfully. The power of PNRS to discriminate the patients with moderate-low risk of developing malnutrition is higher than the patients with high risk. PNRS is considered a valid and reliable tool to establish the risk of malnutrition in the hospitalized patients.
背景/目的：我们旨在对土耳其版儿科营养风险评分（PNRS）进行有效性和可靠性分析。
研究组由 149 名年龄在 1 个月至 18 岁之间、住院时间至少 48 小时的患者组成。记录患者的年龄、性别、人体测量学指标、住院时间、入院诊断、每日体重、食物摄入量和疼痛状况。将其翻译成土耳其语并进行了前后翻译。由两名不同的医生进行 PNRS 评估。评估 PNRS 结果的一致性以确定其有效性。计算了灵敏度、特异性、阳性预测值（PPV）和阴性预测值（NPV）。
所有患者中，69 名（46.3%）为女性，80 名（53.7%）为男性。平均住院时间为 7.3±4.0 天。患者的平均年龄为 51.9±63.6 个月。两名医生之间的 Kappa 系数为 0.66。高风险组中有 65.2%的患者出现体重减轻，低风险组中有 25.4%的患者出现体重减轻。医院营养不良率为 31.5%。摄入<50%食物和病情更严重的患者风险更高。PNRS 的特异性、灵敏度、NPV 和 PPV 分别为 82.1%、77.8%、92.0%和 58.3%。
良好的一致性表明土耳其验证成功。PNRS 区分中低营养不良风险患者的能力高于高风险患者。PNRS 被认为是一种有效且可靠的工具，可用于确定住院患者的营养不良风险。
