Background: identifying children at risk of developing childhood sarcopenic obesity often requires specialized equipment and expensive testing procedures, so cheaper and quicker methods would be advantageous, especially in field-based settings. Objective: the purpose of this study was to determine the relationships between the muscle-to-fat ratio (MFR) and relative handgrip strength, and to determine the ability of handgrip strength relative to body mass index (grip-to-BMI) to identify children who are at risk of developing sarcopenic obesity. Material and method: grip-to-BMI was measured in 4021 Macedonian children (6 to 10 yrs). Bioelectrical impedance was used to estimate body fat mass and skeletal muscle mass, from which the MFR was calculated. Results: the area under the curve (AUC) was 0.771 (95 % CI, 0.752 to 0.789, p < 0.001) in girls 6-10 years old and 0.843 (95 % CI, 0.826 to 0.859, p < 0.001) in boys 6-10 years old. Calculated using the grip-to-BMI ratio, the OR (95 % CI) for girls to be at risk of sarcopenic obesity identified by MFR was 20.182 (10.728-37.966, p < 0.001) and was 16.863 (10.782-26.371, p < 0.001) for boys. Conclusion: the grip-to-BMI ratio can be used to predict the presence of sarcopenic obesity in children, which can play a role in pediatric health interventions.
识别有发生儿童少年期肌肉减少性肥胖风险的儿童往往需要专门的设备和昂贵的检测程序，因此更便宜、更快捷的方法将是有利的，尤其是在现场环境中。目的：本研究旨在确定肌肉-脂肪比（MFR）与相对握力之间的关系，并确定相对握力与体重指数（握力-体重指数）的比值识别有发生肌肉减少性肥胖风险的儿童的能力。材料和方法：在 4021 名马其顿儿童（6 至 10 岁）中测量握力-体重指数。生物电阻抗用于估计体脂肪量和骨骼肌量，从中计算出 MFR。结果：在 6-10 岁女孩中，曲线下面积（AUC）为 0.771（95 % CI，0.752 至 0.789，p < 0.001），在 6-10 岁男孩中为 0.843（95 % CI，0.826 至 0.859，p < 0.001）。使用握力-体重指数比值计算，女孩 MFR 确定的肌肉减少性肥胖风险的比值比（OR）（95 % CI）为 20.182（10.728-37.966，p < 0.001），男孩为 16.863（10.782-26.371，p < 0.001）。结论：握力-体重指数比值可用于预测儿童肌肉减少性肥胖的发生，这在儿科健康干预中可能发挥作用。
