BACKGROUND & AIMS: This study aimed to examine the anthropometric measurements of adolescents between the ages of 10 and 13, and to determine the BMI-for-age-based neck circumference (NC) and BMI-for-age-based mid-upper-arm circumference (MUAC) cut-off points for this age group.
This methodological study was conducted with 626 students of early adolescent age in Kırklareli in Turkey. The cut-off values of BMI-for-age-based NC and MUAC were determined by ROC analysis from severe thinness to obesity. The most suitable AUC value was evaluated according to LR(+) and LR(-) and Sensitivity and Specificity were shown.
The frequency of severe thinness, thinness, overweight, obese among adolescents was 8.0%, 8.9%, 11.7%, and 16.3%, respectively. WHpR of 14.4% of the adolescents was ≥0.90 in boys and ≥0.85 in girls. According to WHtR, 23.8% had a value of <0.40 and, 17.8% had a value of ≥0.50. BMI-for-age-based NC cut-off points were severe thinness, thinness, overweight, obesity 25.50, 26.50, 29.50, 30.50 cm in girls, respectively; 26.50, 27.50, 30.50, 31.50 cm in boys, respectively. BMI-for-age-based MUAC cut-off points were severe thinness, thinness, overweight, obesity 19.50, 20.50, 24.50, 25.50 cm in girls, respectively; 19.50, 20.50, 25.50, 26.50 cm in boys, respectively.
Double burden of malnutrition was identified in early adolescents. The cutoff points for NC and MUAC found in this study showed good specificity to identify double burden of malnutrition in early adolescents and can be used as a reference in especially in cases of insufficient resources or isolated environments.
本研究旨在研究 10 至 13 岁青少年的人体测量指标，并确定该年龄段基于 BMI 的颈围（NC）和 BMI 对应的上臂中部周长（MUAC）的截断值。
本方法学研究在土耳其基尔克拉雷利对 626 名青少年进行。通过从严重消瘦到肥胖的 ROC 分析，确定了基于 BMI 的 NC 和 MUAC 的截断值。根据 LR(+)和 LR(-)评估最合适的 AUC 值，并显示敏感性和特异性。
青少年中严重消瘦、消瘦、超重和肥胖的发生率分别为 8.0%、8.9%、11.7%和 16.3%。男孩的 WHpR 为 14.4%，≥0.90；女孩的 WHpR 为 14.4%，≥0.85。根据 WHtR，23.8%的青少年的数值<0.40，17.8%的青少年的数值≥0.50。基于 BMI 的 NC 截断点分别为女孩严重消瘦、消瘦、超重、肥胖为 25.50、26.50、29.50、30.50 cm；男孩分别为 26.50、27.50、30.50、31.50 cm。基于 BMI 的 MUAC 截断点分别为女孩严重消瘦、消瘦、超重、肥胖为 19.50、20.50、24.50、25.50 cm；男孩分别为 19.50、20.50、25.50、26.50 cm。
在青少年中发现了双重营养不良负担。本研究中发现的 NC 和 MUAC 的截断值对识别青少年的双重营养不良具有良好的特异性，可在资源不足或孤立环境中作为参考。
