摘要

背景:在社区层面及时、准确地筛查营养不良对于识别营养不良儿童至关重要。世界卫生组织(WHO)指南采用中上臂围(MUAC)或体重身高Z值(WHZ)对儿童非水肿性急性营养不良进行分类。研究设计:横断面研究。研究方法:横断面研究:研究对象为 6-60 个月大的儿童。经过必要的排除后,采用多阶段简单随机抽样法选出了 433 名参与者。采用世界卫生组织的全球急性营养不良(GAM)指南[WHZ<-2,MUAC<12.5厘米],以WHZ为标准,计算了MUAC的灵敏度(Se)、特异度(Sp)、预测值、似然比、Youden指数和接收者操作特征曲线(ROC)。结果显示在 433 名参与者中,30% 通过 WHZ 诊断为 GAM,17.6% 通过 MUAC 测量发现为营养不良。根据世界卫生组织的临界值,MUAC 的 Se、Sp、阳性预测值(PPV)、阴性预测值(NPV)、Youden 指数、阳性似然比(LR+)和阴性似然比(LR-)分别为 48%、96%、83%、81%、0.44、12 和 0.54。MUAC<12.5 厘米的 ROC 曲线显示曲线下面积为 0.86(95% 置信区间=0.83,0.90)。双变量皮尔逊相关性也表明,WHZ 和 MUAC 变量之间存在正线性关系(R2=0.302)。结论根据研究结果,48% 的儿童通过 MUAC 被正确识别,GAM 的概率为 83%(PPV=0.83)。此外,非营养不良儿童的 Sp 值为 96%,假阳性率仅为 4%。因此,由于 MUAC 易于使用且操作简单,基层工作人员可在 Anganwadi 中心(AWCs)使用 MUAC 对儿童进行及时、准确的筛查。

Diagnostic Accuracy of Mid-Upper Arm Circumference for the Detection of Acute Malnutrition Among Children Aged 6–60 Months: A Diagnostic Accuracy Study
Background: Timely and accurate screening of malnutrition at the community level is essential to identifying malnourished children. The World Health Organization (WHO) guidelines classify non-oedematous acute malnutrition among children using mid-upper arm circumference (MUAC) or weight-for-height Z-score (WHZ). Study Design: A cross-sectional study. Methods: This study was conducted among children aged 6‒60 months. After necessary exclusions, 433 participants were selected using a multi-stage simple random sampling method. Using WHO guidelines for global acute malnutrition (GAM) [WHZ<-2, MUAC<12.5 cm], the sensitivity (Se), specificity (Sp), predictive values, likelihood ratios, Youden index, and receiver operating characteristic (ROC) curve were calculated for MUAC using WHZ as the criterion. Results: Out of 433 participants, 30% were diagnosed with GAM using WHZ, while 17.6% were found malnourished using MUAC measurements. As per WHO cut-offs, the Se, Sp, positive predictive value (PPV), negative predictive value (NPV), Youden index, positive likelihood ratio (LR+), and negative likelihood ratio (LR-) of MUAC were 48%, 96%, 83%, 81%, 0.44, 12, and 0.54, respectively. The ROC curve displayed an area under the curve of 0.86 (95% confidence interval=0.83, 0.90) for MUAC<12.5 cm. Bivariate Pearson correlation also demonstrated a positive linear relationship (R2=0.302) between the WHZ and MUAC variables. Conclusion: Based on the findings, 48% of the children were correctly identified by the MUAC with an 83% probability of GAM (PPV=0.83). Moreover, there was 96% Sp in non-malnourished children, with only 4% false positives. Therefore, personnel at the grassroots level can use MUAC for timely and accurate screening of children in Anganwadi centers (AWCs) due to its ease of use and simplicity.
