Mid-upper-arm circumference (MUAC) is considered an alternative screening method for obesity. The aims of this investigation were to examine the ability of MUAC to correctly identify children with elevated body mass index (BMI) and to determine the best MUAC cutoff point for identification of children with high BMI.
Anthropometric measurements (height, weight, and MUAC) from a cross-sectional sample of 7,921 Pakistani children aged 5-14 years were analyzed. Pearson correlation coefficients between MUAC and other anthropometric measurements were calculated. Receiver operating characteristic curve analysis was used to determine the optimal MUAC cutoff point for identifying children with high BMI.
Among 7,921 children, the mean (±standard deviation) age, BMI, and MUAC were 10.00 (±2.86 years), 16.16 (±2.66 kg/m), and 17.73 (±2.59 cm), respectively. The MUAC had a strong positive correlation with BMI. The optimal MUAC cutoff points indicating elevated BMI in boys ranged from 16.76 to 22.73, while the corresponding values in girls ranged from 16.38 to 20.57.
MUAC may be used as a simple indicator of overweight/obesity in children, with reasonable accuracy in clinical settings.
上臂中部周长（MUAC）被认为是一种用于筛查肥胖的替代方法。本研究的目的是检验MUAC正确识别体重指数（BMI）升高儿童的能力，并确定用于识别高BMI儿童的最佳MUAC切点。
对来自7921名5至14岁巴基斯坦儿童的横断面样本进行人体测量（身高、体重和MUAC）分析。计算MUAC与其他人体测量指标之间的Pearson相关系数。采用受试者工作特征曲线分析来确定识别高BMI儿童的最佳MUAC切点。
在7921名儿童中，平均（±标准差）年龄、BMI和MUAC分别为10.00（±2.86岁）、16.16（±2.66kg/m²）和17.73（±2.59cm）。MUAC与BMI呈强正相关。表明男孩BMI升高的最佳MUAC切点范围为16.76至22.73，而女孩的相应值范围为16.38至20.57。
MUAC可作为儿童超重/肥胖的一个简单指标，在临床环境中具有合理的准确性。
