Childhood obesity is one of the most serious public health problems. The prevalence of obesity among children is increasing and may negatively affect their immediate health, but it can also lead to obesity in adulthood. The aim of the study was to compare BMI cut-off points by examining three main international references: the World Health Organization (WHO), the International Task Force Obesity (IOTF) and the US Center for Disease Control and Prevention (CDC). Ultimately, the study group consisted of 18,144 children and adolescents aged 6.5-17.5 years. Body mass was measured on medical scales with an accuracy of ± 100 g and height measurement was taken using a height meter with an accuracy of ± 0.1 cm three times. Underweight, overweight and obesity were calculated according to WHO, IOTF and CDC BMI international references. There were differences in the incidence of underweight between the classifications: 16.8% according to IATF, 5.3% according to WHO and 9.9% according to CDC. There were also differences in the incidence of overweight and obesity between the classifications: 13% according to IOTF, 19.7% according to WHO and 14.1% according to CDC. In the CDC and WHO studies, a significantly higher prevalence of childhood obesity (4.0% and 4.7%, respectively) was observed compared with IOTF (2.1%). The prevalence of overweight and obesity in this study was higher among boys compared to girls. However, estimates of prevalence of overweight and obesity differ in methods and reference cut-off points. Higher prevalence was obtained in IOTF classification, followed by the WHO and CDC classification.
儿童肥胖是最严重的公共卫生问题之一。儿童肥胖的患病率正在增加，可能会对他们的即时健康产生负面影响，但也可能导致成年后肥胖。本研究的目的是通过比较三个主要的国际参考标准（世界卫生组织[WHO]、国际肥胖工作组[IOTF]和美国疾病控制与预防中心[CDC]）来比较 BMI 切点。最终，研究组由 18144 名 6.5-17.5 岁的儿童和青少年组成。体重在医疗秤上测量，精度为±100g，身高使用精度为±0.1cm 的身高计测量三次。根据 WHO、IOTF 和 CDC BMI 国际参考标准计算体重不足、超重和肥胖。根据 IATF、WHO 和 CDC 的分类，体重不足的发生率存在差异：IATF 为 16.8%，WHO 为 5.3%，CDC 为 9.9%。根据分类，超重和肥胖的发生率也存在差异：IOTF 为 13%，WHO 为 19.7%，CDC 为 14.1%。在 CDC 和 WHO 的研究中，与 IOTF（2.1%）相比，儿童肥胖的患病率（分别为 4.0%和 4.7%）显著更高。与女孩相比，男孩超重和肥胖的患病率更高。然而，超重和肥胖的患病率估计在方法和参考切点上存在差异。IOTF 分类的患病率较高，其次是 WHO 和 CDC 分类。
